Objectives : Plantaginis asiaticae Folium (PA) has been widely used in Korean medicine for treatment of liver disease, stomach troubles and inflammation. We investigated the effect of PA on lipid accumulation in 3T3-L1 according to extraction conditions. Methods : The MTT assay was employed to evaluate the cytotoxicity of PA extracted by different solvents (water, 50% ethanol, and 95% ethanol) on 3T3-L1 preadipocytes. Oil red O staining was used to identify intracellular lipid accumulation in 3T3-L1. 3T3-L1 adipocytes were treated with PA at concentration ranging in 0.1, 0.2 and 0.4 ㎎/㎖. PA was extracted by different extraction conditions such as extraction solvents, extraction time, and extraction temperature. In addition, UPLC analysis was used for determination of candidates of active ingredients in PA. Results : 3T3-L1 preadipocytes were treated with PA extracted by different solvents (water, 50% ethanol, and 95% ethanol) and there was no cytotoxicity. Oil red O staining was employed to identify the effect of PA on lipid accumulation in 3T3-L1. In the present study, PA water extraction at 70℃ for 6 hours decreased greatly in lipid accumulation. The range of concentrations was 0.1, 0.2 and 0.4 ㎎/㎖. Concentration at 0.2 ㎎/㎖ was the most effective one among them. Candidates of active ingredients in PA were shown plantamajoside and acteoside through UPLC. Conclusions : These results suggest that the effect of PA water extraction at 70℃ on lipid accumulation in 3T3-L1 is superior to other extraction conditions. We suppose that plantamajoside and acteoside may be candidates of active ingredients in PA.

Objectives : Butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) were well known as anti-oxidant, but they were limited to use because of toxicity. So, many studies are being done to develope natural anti-oxidant. Total phenolic and flavonoid contents along with total antioxidant capacity of the ethanolic extract of Plantaginis Herba (PH) were evaluated to explore the reliable and potential sources of novel natural antioxidants. Methods : Total polyphenol contents and total flavonoid contents in PH ethanol extract were determined by colorimetric method. And DPPH(1.1-diphenyl-2-picrylhydrazyl), ABTS(2'-azino-bis (3-ethylbenzothiazoline-6-Surfonicacid)) free radical scavenging capacity and reducing power inhibition activities of PH ethanol extract were measured at 100, 500, 1000, 5000 ㎍/㎖ concentrations by spectrometric assay. Results : The total polyphenol contents and total flavonoid contents of the extract were 161.99 ㎎/g, 144.05 ㎎/g, respectively. Also, DPPH, ABTS free radical scavenging capacity and reducing power of PH ethanol extract in treated concentrations (100, 500, 1000, 5000 ㎍/㎖) increased dose dependently. In particular, DPPH free radical scavenging capacity of PH ethanol extract from 500 ㎍/㎖ was significantly increased compared to positive control (BHA). ABTS free radical scavenging capacity of PH ethanol extract from 1000 ㎍/㎖ was significantly higher than BHA. Also, reducing power showed that PH ethanol extract from 500 ㎍/㎖ was significantly increased compared to BHA. Conclusions : These results suggest that PH ethanol extract has effects to scavenge free radicals, thus PH has potential and applicable benefits for development of materials and products to have anti-oxidation functions.

Objective : Plantago asiatica L. has been used for many years in Korea, China, and Japan for the treatment of many diseases such as anti-inflammatory, anti-asthma and diuretic. But the anti-obesity effect of Plantaginis asiaticae Folium has not been studied yet. Thus, this study aimed to demonstrate the anti-obesity efficacy of Plantaginis asiaticae Folium water extract (PAF) in high fat diet-induced obesity animal model. Method : Male, five-weeks old C57BL/6 mice were divided into 5 groups; ND (normal diet + 0.9% saline), HFD (highfat diet + 0.9% saline), PC (high-fat diet + Garcinia cambogia 500 ㎎/㎏), PAF 100, 300 (high-fat diet + PAF 100, 300 ㎎/㎏. Treatments were performed daily for 6 weeks per os. We evaluated the changes of body weight, white adipose tissues weight, hepatic and fecal lipids level, pancreatic lipase activity and lipid profiles in plasma. Result : Body weights, adipose tissue weights and FER were significantly lower in mice fed the high-fat diet with PAF treatment than in mice fed the high-fat diet alone. In plasma, TG, TC, LDL-C, ATS and ALT levels significantly decreased in PAF groups compared with HFD group. Also, hepatic triglyceride (TG) levels decreased and fecal TG increased in PAF groups compared to HFD group. In addition, the activity of pancreatic lipase was decreased in the PAF groups compared to that of HFD group. Conclusion: These results suggest PAF extract is effective in preventing and improvement obesity, so it might be a potential and safe material for anti-obesity agent of weight control or functional supplements.

차전초 잎의 물 추출물이 고지방식이로 비만이 유도된 C57BL/6 생쥐에서 지질대사 단백질 발현에 미치는 영향

Objective : Previous studies showed that water extract of Plantago asiatica (Plantaginis asiaticae Folium, PAF) significantly controlled in body weights, adipose tissue weights and blood lipid profiles in obese C57BL/6 mice. To investigate the mechanism of anti-obesity action of PAF, expressions of obesity-related proteins were identified such as p-AMPK and p-ACC in hypothalamus, UCP-1 in brown adipose tissue, p-AMPK, p-ACC, SREBP-1c, PPARγ, HMGCR and CPT-1 in liver. Method : Five-weeks old male C57BL/6 mice were divided into 5 groups; ND (normal diet + 0.9% saline), HFD (high-fat diet + 0.9% saline), PC (high-fat diet+Garcinia cambogia 500 ㎎/㎏), PAF 100 and 300 (high-fat diet + PAF 100 or 300 ㎎/㎏). PAF was treated orally for 6 weeks. The protein expression of AMPK, p-AMPK, ACC, p-ACC, PPARγ, SREBP-1c, HMGCR, CPT-1 and UCP-1 were identified by expression levels of proteins through western blot analysis. Result : The results showed that protein expressions on hypothalamic p-AMPK and p-ACC did not differ between the HFD and PAF groups. In addition, PAF did not affect the increase of UCP-1 in brown adipose tissue. The protein expression levels of hepatic p-AMPK, p-ACC and CPT-1 increased in PAF groups compared to HFD group. And those of PPARγ, SREBP-1c and HMG-CoA decreased in PAF groups compared to HFD group. Conclusion : These results suggest that the PAF administration induce weight loss via inhibition of lipid metabolism-related protein expressions in hepatic tissues. Therefore, PAF could be used as a potent material of anti-obesity products for prevention and treatment of obesity.
