무모쥐의 피부에 도포한 애엽 추출물과 positive 비교군인아스코르브산이 피부 조직에 미치는 항산화효과를 조사하였다. 활성산소인 과산화수소의 생성량은 애엽 추출물과 아스코르브산 2%와 5% 도포군에서 유의적으로 감소하였다. 히드록시 라디칼의 생성량은 애엽 추출물 2%와 5% 도포군에서만 유의적인 감소효과가 있었다. 산화적 스트레스의 지표인 산화 단백질의 함량은 모든 애엽 추출물 도포군에서 대조군에 비해 유의적으로 감소(14.6%~18.5%)하였으나, 아스코르브산의 경우는 2% 도포군에서만 저해효과가 인지되었다. 과산화지질 생성량은 대조군에 비해 애엽 추출물과 아스코르브산 도포그룹 모두에서 크게 감소하였다. 항산화효소인 카탈라아제의 활성은 애엽 추출물과 아스코르브산 모든 그룹에서 첨가 농도가 증가함에 따라 크게 증가하였으며, 글루타치온 퍼옥시다아제의 활성은 애엽 추출물 도포군은 2%와 5%에서, 아스코르브산의 경우는 모든 그룹에서 유의적인 활성 증가를 보였다. 이상의 결과는 피부 노화 억제기능성 화장품 소재로서 애엽 추출물의 활용 가능성을 제시한다. This study investigated the antioxidative effect of mugwort (Artemisia vulgaris L.) extracts in hairless mouse skin from oxidative stress induced by UV-irradiation. After topical application on hairless mouse back with basic skin lotion group (control), ascorbic acid group (AA-0.5%, AA-1.0%, AA-2.0%, and AA-5.0%), and mugwort extract group (ME-0.5%, ME-1.0%, ME-2.0%, and ME-5.0%), the animals were irradiated to increasing doses of UVB (60 mJ~100 mJ) for 4 weeks. Hydrogen peroxide of hairless mouse skin homogenate significantly decreased in 2% (p<0.05) and 5% (p<0.05) of ME and AA groups. Hydroxyl radicals were decreased significantly in both of 2% and 5% ME groups as compared to AA groups (p<0.05). Oxidative stress levels deduced by oxidized protein contents were greatly decreased (14.6~18.5%) in all ME treatment groups, while only at 2% of AA treatment group. Lipid peroxide contents were greatly inhibited in all ME and AA treatment groups (p<0.01). Application of ME significantly increased catalase activity, over 25% in all mugwort and AA groups. Glutathione peroxidase activities were increased up to 20.5%~32.8% in 2.0% and 5% ME groups, whereas it increased in all AA groups. These results suggested that mugwort extract was more effective than that of ascorbic acid in protecting hairless mouse skin from photo-irradiation, and can be used as an potential anti-aging cosmetic ingredients.

박시향(Si-Hyang Park),홍유미(Yumi Hong),최영준(Yeung Joon Choi),최진호(Jin-Ho Choi),김병관(Byung-Kwan Kim) 한국식품영양과학회 2008 한국식품영양과학회지 Vol.37 No.9

무모쥐의 등에 애엽 추출물과 아스코르브산 함유 스킨로션을 도포하고 자외선을 조사하여 애엽 추출물과 아스코르브산의 주름 개선 효과를 알아보았다. 애엽 추출물 도포군의 피부조직 두께는 대조군에 비해 12.5~21.4%의 유의적인 감소 효과를 보였다. 표면 거칠기 측정기에 의한 피부 주름의 형성 정도를 측정하는 지표인 Ra값은 ME-1.0, ME-2.0과 ME-5.0 도포군에서 23.7~31.1%로 유의적으로 감소하였고 (p<0.01), Rq치는 ME-1.0, ME-2.0와 ME-5.0에서 11.2~21.2%, Rz의 측정치에서는 ME-1.0(19.8%), ME-2.0(22.1%), ME-5.0(24.5%) 그룹에서 대조군에 비해 크게 감소하였다. Rt치는 ME-1.0, ME-2.0와 ME-5.0 그룹에서 농도 증가에 따라 14.2%에서 22.7%의 유의적인 감소효과가 있었다. 아스코르브산 도포그룹은 애엽과 비슷한 감소효과를 보여주었지만, 애엽의 주름 개선효과에는 미치지 못하였다. MMP-1 활성은 애엽 메탄올 추출물 그룹에서 19.3%~22.6%까지 감소하였고, 콜라겐의 생성은 ME-2.0과 ME-5.0그룹에서 10% 정도의 유의적인 증가 효과가 있었다. 이처럼 애엽 메탄올 추출물은 피부의 광손상에 대한 피부 보호 및 피부의 주름 개선효과가 탁월하고, 또한 강력한 항산화제인 아스코르브산보다 그 효과가 우수하여 피부노화 현상과 주름 개선을 위한 기능성 화장품 소재로 이용가치가 있을 것으로 여겨진다. This study was to investigate antiwrinkle effect of mugwort (Artemisia vulgaris) methanol extract in hairless mouse skin induced by UVB-irradiation. Hairless mouse were topically treated with the basic lotion alone (control), ascorbic acid (AA-0.5%, AA-1.0%, AA-2.0%, and AA-5.0%) and mugwort extract (ME-0.5%, ME-1.0%, ME-2.0%, and ME-5.0%) dissolved in a basic lotion. After topical treatment of 30 minutes, the animals were irradiated with increasing doses of UVB radiation (60~100 mJ/㎠) for 4 weeks. In our experimental condition, skin thickness of hairless mouse was significantly decreased (12.5~21.4%) in all ME groups compared with control group. Ra value, that is surface roughness parameter induced by skin wrinkling, was significantly decreased (23.7~31.1%) in ME-1.0%, 2.0% and 5.0% group compared with control group. Furthermore, Rq, Rz and Rt value were significantly decreased to 11.2~21.2%, 19.8%~24.5%, and 14.2%~22.7%, respectively. Wrinkle formation of ascorbic acid treatment group as reference group was inhibited, but its effect was less than ME treatment. Matrix metalloproteinase-1 activity was significantly inhibited (19.7~22.6%) compared with control group and collagen content was significantly increased (about 10%) when compared with control group. These results indicate that ME could protect skin aging and wrinkle formation in hairless mouse from photo-irradiation.

박시향(Si-Hyang Park),문성실(Sung-Sil Moon),Cheng-Liang Xie,정세영(Se-Young Choung),최영준(Yeung-Joon Choi) 한국식품영양과학회 2014 한국식품영양과학회지 Vol.43 No.8

본 연구는 굴 가수분해물이 아세트아미노펜에 의한 간독성의 무독화 효과를 HepG-2 세포를 사용하여 조사하였다. 굴 가수분해물은 굴 단백질의 가교연결을 위해 TGase로 전처리하거나(TGPN) 혹은 하지 않고(PN), 1% Protamex와 1% Neutrase 단백질 분해효소로 2단 가수분해하였다. 두 종류의 굴 가수분해물은 아세트아미노펜으로 간 손상을 유도한 세포에 각각 처리하여 세포 생존율을 측정하였으며, 세포 배양 시 배양액으로 유출된 GOT와 GPT 활성을 측정하였다. TGPN 가수분해물의 경우 아세트아미노펜만을 처리한 negative 대조군(60.7±3.2%)에 비하여 100 μg/mL와 200 μg/mL의 농도에서 각각 136.2±1.4%와 179.6±3.8%의 높은 세포 생존율을 보였다. PN 가수분해물은 100 μg/mL와 200 μg/mL의 농도에서 각각 107.9±8.8%와 130.6±7.6%의 세포 생존율을 보였다. GOT 활성은 negative 대조군의 경우에 38.3±0.2 Karmen/mL이었으며, TGPN(200μg/mL)과 PN(200 μg/mL)에서는 19.9±0.5와 22.0±2.4 Karmen/mL로 농도에 따라 유의적인 활성 감소를 확인할 수 있었다. 그리고 GPT 활성도 GOT와 같은 경향의 활성을 나타내었다. 이 같은 결과에 미루어 굴 유래 가수분해물의 간 보호 건강 기능 식품 혹은 약물 개발의 가능성을 확인하였으며 앞으로 가수분해 펩티드 중의 유효성분에 대한 구조동정과 작용 기전에 관한 연구가 필요할 것으로 보인다. This study investigated the detoxification effects of enzymatic hydrolysate from oyster on acetaminophen-induced toxicity using HepG-2 cells. Oyster hydrolysate was made with 1% Protamex and 1% Neutrase after treatment with transglutaminase (TGPN) or without (PN). Two types of oyster hydrolysate were added to human-derived HepG-2 hepatocytes damaged by acetaminophen, after which the survival rate of HepG-2 cell was measured. In addition, glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) activities in the culture media were evaluated. The survival rates of HepG-2 cells were 136.2±1.4% at 100 μg/mL of TGPN and 179.6±3.8% at 200 μg/mL of TGPN. These cell survival rates were higher compared to that of the negative control group (60.7±3.2%) treated only with acetaminophen. GOT activity was 38.3±0.2 Karmen/mL in the negative control group, whereas it was 19.9±0.5 for TGPN (200 μg/mL) and 22.0±2.4 Karmen/mL for PN (200 μg/mL). GOT and GTP activities were shown to be dependent on TGPN concentration, and significant reduction in activities could be conformed. The detoxification efficacy of TGPN was higher compared to that of PN. These results suggest that oyster hydrolysate has potential as a healthy food or pro-drug for liver protection.

박시향(Si?Hyang Park),조득문(Duck?Moon Cho),최경림(Gyeonglim Choi),최영준(Yeung Joon Choi),최진호(Jin?Ho Choi) 한국식품영양과학회 2007 한국식품영양과학회지 Vol.36 No.12

애엽 추출물에 대한 ICR 마우스의 피부 조직에 대한 항산화작용 및 산화적 스트레스에 미치는 영향을 조사하였다. 애엽 추출물(mugwort extract: ME)을 섭취한 식이군의 경우, 추출물의 농도에 따라 피부조직의 단백질 함량이 대조군에 비해 3.1%~11.1% 증가하였다. 활성산소 중 히드록시 라디칼 함량은 애엽 추출물 식이군에서 10.4%~17.4%의 유의적인 감소 효과가 인정되었으며, 그리고 산화적 스트레스로써 산화단백질의 함량도 애엽 추출물 식이군(ME-100, ME-200)이 대조군에 비해 각각 15.2%와 17.1%의 유의적인 감소를 보였다(p<0.05). 과산화지질함량은 애엽 추출물의 농도증가에 따라 감소되는 경향을 보여주었으나, 통계적인 유의성은 없었다. 수퍼옥시드 디스무타아제 활성은 ME-100 군과 ME-200 군에서 각각 15.0%와 23.3%의 유의적인 증가가 있었고, 또한 애엽 추출물의 농도가 증가할수록 카탈라아제 활성도 증가하는 것으로 나타났다. 애엽 추출물의 섭취가 피부의 활성산소를 제거하고 산화적 스트레스를 억제하며, 항산화효소의 활성을 증가시켜 피부의 노화현상을 억제시키는 효과가 있음을 확인할 수 있었다. 강력한 항산화제인 아스코르브산과 비교하여도 손색이 없는 높은 활성을 보였다. 이와 같은 결과는 피부 건강기능 식품과 음료 소재로서 애엽의 이용 가능성을 제시한다. The feeding effects of mugwort (Artemisia vulgaris L.) extracts (ME) on the anti-oxidative actions of ICR mouse skin was investigated. To study the antioxidative effects of ME on ICR mouse skin, female ICR mice were grouped into basic diet group (control), ascorbic acid diet group (AA-2.5, AA-5.0, AA-10.0 and AA-20.0 ㎎/㎏ BW/day) as a positive control and experimental diet group (mugwort extract; ME-25, ME-50, ME-100, and ME-200 ㎎/㎏ BW/day) and fed for 10 weeks. Protein contents in ME-50, ME-100, and ME-200 feeding group were increased (3.1%~11.1%) and hydroxyl radical contents were significantly decreased (10.4%~17.4%) compared to control group. Oxidative stress signals and oxidized protein contents were significantly reduced to the range of 15.3 to 17.1% in ME-100 and ME-200 groups. Also, superoxide dismutase (SOD) activity was significantly increased to the range of 15.0% to 23.3% in ME-100 and ME-200 groups. Catalase activities were significantly increased (14.0%~36.9%) in all groups in a dose-dependent pattern. Antioxidative ability of ME showed similarity to that of ascorbic acid.

이수선(Su-Seon Lee),박시향(Si-Hyang Park),김현아(Hyeun-A Kim),최영준(Yeung-Joon Choi) 한국식품영양과학회 2016 한국식품영양과학회지 Vol.45 No.4

굴 가수분해물의 이취 제거를 위한 가수분해 및 발효의 최적 조건과 이의 항산화 효과를 검토하였다. 이취 제거를 위한 굴 가수분해물의 최적 추출 조건은 Neutrase를 이용하여 E/S 3.3%, 50°C, 8.3시간이었으며, 발효 공정은 24°C에서 glucose 0.5%와 Saccharomyces cerevisiae를 5% 접종하였다. 굴 가수분해 발효물의 구성 아미노산은 25.7%에 해당 하였으며, Glu, Asp, Lys, Leu, Arg, Gly 및 Ala이 전체의 61.2%를 차지하였다. 유리 아미노산 조성의 경우 Leu, Ala, Phe, Val 및 Tau의 순으로 높게 나타났다. 또한 무기질 함량은 Na, P, K, Zn, Fe이 높게 나타났으며, 정상 간세포주인 Chang cell에 대한 독성은 나타나지 않았다. 이상의 결과로 미루어 S. cerevisiae에 의해 수산물의 이미취를 masking 할 수 있으나, 기능성 원료로 사용하기 위해 최종 제품의 카드뮴 함량을 저감시킬 대책이 필요하다. This study was carried out to investigate the optimal processing conditions for odor removal and maximal antioxidant effects of oyster (Crassostrea gigas) hydrolysate. The optimal hydrolysis conditions were 3.3% neutrase as the protease, 50°C as the hydrolysis temperature, and 8.3 h as the hydrolysis time. Fish odor of enzymatic oyster hydrolysate was greatly reduced during Saccharomyces cerevisiae fermentation at 24°C with 0.5% glucose. The protein content of the fermentation product from oyster hydrolysate powder was 25.7%, which contained the major amino acids Glu, Asp, Lys, Arg, Gly, and Ala, whereas Leu, Ala, Phe, Val, and Tau were abundant free amino acids. The important minor minerals were Zn and Fe. Toxicity against Chang cells was not observed in the fermentation product from the oyster hydrolysate up to 200 μg/mL. The results suggest that fermentation with S. cerevisiae could reduce the fish odor of enzymatic oyster hydrolysate. The hydrolysate has potential application as a food ingredients and nutraceutical.

In this study, we evaluated the anti-oxidative, anti-wrinkle and whitening effect of Duchesnea indica (Andr.) Focke extract. Duchesnea indica (Andr.) Focke was extracted by two different solvents which were n-hexane and ethyl acetate. The anti-oxidant activity was measured by free radical scavenging activity using DPPH (1,1-diphenyl-2-picrylhydrazyl radical). And the inhibitory activities of tyrosinase for whitening effect and collagenase for anti-wrinkle were investigated. For anti-oxidant activity and whitening activity, ethyl acetate fraction of Duchesnea indica (Andr.) Focke extract showed more significant activity than n-hexane fraction of Duchesnea indica (Andr.) Focke extract. For anti-wrinkle activity, ethyl acetate fraction of Duchesnea indica (Andr.) Focke extract exhibited strong inhibition effects compared with reference. Therefore, Duchesnea indica (Andr.) Focke extract may be useful as a new antioxidant and anti-aging agent.

김현아(Hyeon-Ah Kim),박시향(Si-Hyang Park),이수선(Su-Seon Lee),최영준(Yeung Joon Choi) 한국식품영양과학회 2015 한국식품영양과학회지 Vol.44 No.11

해양생물 유래 피부건강 기능성의 소재를 발굴할 목적으로 굴 단백질을 Protamex와 Neutrase로 가수분해 한 후 생성된 굴 가수분해물 펩타이드의 주름 개선 효과를 조사하였다. 굴 가수분해물은 약 7.9%의 유리아미노산을 포함하며 urea, taurine, alanine, glycine 등의 아미노산의 함량이 높았다. 굴 가수분해물은 collagenase 저해 활성을 가지고 있었고, 피부세포인 CCD986sk에 대한 독성은 없었다. 분획물의 수율은 1,000 Da 미만이 40%였으며, 5,000 Da 미만이 60.4%를 차지하였다. 1,000~3,000 Da인 분획물이 항산화 활성, procollagen의 생성능 및 MMP-1 효소 저해 활성이 가장 높았다. 굴 가수분해물과 5,000 Da 미만의 분획물은 주름 개선을 위한 피부건강 기능성 소재로서 화장품 등의 제품에 응용 가능함을 확인하였다. We investigated the anti-wrinkle efficacy of hydrolysate from oyster protein by Protamex and Neutrase for the purpose of finding materials to assist skin health originating from marine organisms. There were about 7.9% free amino acids in the oyster hydrolysate, and contents of urea, taurine, alanine, and glycine were high. Oyster hydrolysate also showed collagenase inhibitory activity and was not toxic to CCD986sk human fibroblast cells. Yield of the fractions according to the molecular weight of oyster hydrolysate was 40% for less than 1,000 Da and 60.4% for less than 5,000 Da, respectively. Antioxidative effect, procollagen production, and matrix metalloproteinase-1 inhibitory activity were highest in 1,000∼3,000 Da fractions. We observed that oyster hydrolysate and its less than 5,000 Da fraction are potential functional compounds for skin health and for improving wrinkles.

굴 가수분해물이 SD-Rat의 혈청과 간 균질물에 미치는 항산화 효과

허성익(Sung-Ik Hur),박시향(Si-Hyang Park),이수선(Su-Seon Lee),정세영(Se Young Choung),최영준(Yeung Joon Choi) 한국식품영양과학회 2013 한국식품영양과학회지 Vol.42 No.12

This study is conducted to investigate the antioxidative effect of oyster hydrolysates in the serum and liver of SD-rats through the determination of lipid content, production of free radicals and antioxidant enzyme activities. Two different hydrolysates, Protamex-treated and Neutrase-treated hydrolysate with the cross-linking of protein by transglutaminase (TGPN group) and without (PN group), were fed for 6 weeks. TGPN hydrolysate in serum and liver significantly decreased the total cholesterol in the range of 26.1% to 28.9%, and triglyceride in the liver of up to 6.3%. Superoxide radical in the serum and lipid peroxide radical in the liver were significantly decreased in SD-rats fed 200 mg TGPN hydrolysate. Superoxide dismutase activity was significantly decreased in the liver of SD-rats. These results indicate that TGPN hydrolysate could scavenge the superoxide and hydroxyl radicals, and reduce the superoxide dismutase and catalase activities. The TGPN is also protected the oxidation of protein by the free radicals.

This study was performed to assess the antioxidative properties of lipid from aquacultured mackerel Scomber japonicus fed with a diet fortified with conjugated linoleic acid (CLA) and ascidian Halocynthia roretzi tunic extracts by radical scavenging assay. The fish were separated into squid oil (Control) and 2.5% CLA (CA25) groups during the 8-week feeding period. The reducing power of each sample showed high levels of activity compared with α-tocopherol and butylated-hydroxyanisol (BHA) at 0.2-1.0 mg/mL of lipid. Inhibition of linoleic acid oxidation in samples from Control and CA25 groups showed similar activity after 2 days of incubation at 40℃. The 2,2-diphenyl-1-picrylhydrazyl (DPPH), superoxide, and hydroxyl radical scavenging activities of CLA and carotenoid-deposited sample (CA25) were higher than those of the Control group. The results indicated that the lipid extracted from the viscera of mackerel showed slightly higher antioxidant activities than that from the muscle.
