한국산 백복령 중 트리터페노이드 성분의 분리 및 구조 확인에 관한 연구
문순구,민태진,Moon, Soon-Ku,Min, Tae-Jin 생화학분자생물학회 1987 한국생화학회지 Vol.20 No.2
한국산 백복령을 클로로포름으로 추출한 다음 주된 트리터페노이드 성분을 분리, 정제하여 그 구조를 확인하였다. 추출액의 잔사를 메탄올로 재결정하여 주 트리터페노이드 성분(A-성분)을 분리하여, 메틸에스테르화(A-OMe 성분)시킨후 GC 및 역상HPLC에 의하여 2개의 성분 즉 $A_1$-OMe 및 $A_2$-OMe 성분을 분리하였다. 이 2개의 성분을UV, IR, $^1H$-NMR, $^{13}C$-NMR, FAB-mass 스펙트럼 및 원소 분석에 의하여 구조를 확인한 결과 $A_1$-OMe 성분은 methyl $3{\beta}$-hydroxylanosta-7,9(11),24-trien-21-oate이었고, $A_2$-OMe 성분은 methyl dehydroeburicoate와 methyl trametenolate의 혼합물이었다. The triterpenoids in the Korean White Poria cocos(Schw.)Wolf were extracted with chloroform and the major component (A-component) was isolated to pure state by recrystallization in methanol. A-component and its methyl ester (A-OMe component) were analyzed by GC and HPLC under various conditions. A-OMe was isolated to two components ($A_1$-OMe and $A_2$-OMe) by reverse phase HPLC. The structure of $A_1$-OMe was determined as methyl $3{\beta}$-hydroxylanosta-7,9(11),24-trien-21-oate and $A_2$-OMe was presumed as mixture of methyl dehydroeburicoate and methyl trametenolate, by UV, IR, $^1H$-NMR, $^{13}C$-NMR, FAB-mass and elemental analysis.

The triterpenoids in the Korean White Poria cocos(Schw.)Wolf were extracted with chloroform and the major component (A-component) was isolated to pure state by recrystallization in methanol. A-component and its methyl ester (A-OMe component) were analyzed by GC and HPLC under various conditions. A-OMe was isolated to two components (A₁-OMe and A₂-OMe) by reverse phase HPLC. The structure of A₁-OMe was determined as methyl 3β-hydroxy lanosta-7,9(11),24-trien-21-oate, and A₂-OMe was presumed as mixture of methyl dehydroeburicoate and methyl trametenolate, by UV, IR, ^1H-NMR, ^(13)C-NMR, FAB-mass and elemental analysis.

백복령 Whit Poria Cocos(Schw.) Wolf중의 지방산 성분에 관한 연구
閔泰鎭,文順九 동국대학교 대학원 1986 大學院硏究論集-東國大學校 大學院 Vol.16 No.-
The quantitative analysis of phospholipids, sterols, proteins, free sugars and fatty acids in Korean White Poria cocos(Schw.) Wolf were performed. Dry powder of sample was extracted with chloroform : methanol(2 : 1 v/v) mixed solvent. The extract was saponified and methylated, and then analyzed by gas chromatograpy. Total 24 peaks were observed and 5 peaks i.e., C_(8:0); caprylic acid, C_(11:0); undecanoic acid, C_(12:0); lauric acid, C_(12:1); dodecenoic acid, C_(16:0); palmitic acid were identified. Major components were C_(8:0) and C_(12:1) and were determined as 6.657ug and 10.176ug pergam, respectively. Total phospholipids, sterols, proteins and free sugars were determiened 3.233mg, 0.507mg 7.644mg and 2,420mg per gram, respectively.

복령의 Carboxyl Proteinase 의 분리 정제 및 그 성질에 관한 연구 (2)
민태진,박상신,문순구 한국균학회 1986 韓國菌學會誌 Vol.14 No.2
The properties of carboxyl proteinase which was contained is Poria cocos (Schw.) Wolf were investigated by means of the purification with 0.65 ammonium sulfate saturation, DEAE-cellulose sad Sephadex G-75 gel filtration. This enzyme was found to hydrolyze only peptide bond between glutamyl-L-tyrosine of carbobenzoxy-L-glutamyl-L-tyrosine among the synthetic substrates of carbobenzoxy-L-glutamyl-L-tyrosine, hippuryl-L-phenylalanine and hippuryl-L-arginine. This enzyme was inhibited by Zn^(+2), Fe^(+2), Ca^(+2), CN^(-1), P₂O_7^(-1) ions, but stimulated by Hg^(+2) ion. Also, this enzyme was inhibited by organic compounds such as L-lysine, L-phenylalanine, hippuryl-L-phenylalaniae, diazoacetyl-DL-norleucine methyl ester (DAN) and 1.2-epoxy-3-(P-nitrophenoxy)propane(EPNP). In particular, the activity was inhibited by L-lysine till 20 minutes of preincubation time rapidly, and by DAN in the presence of Cu^(+2) ion more rapidly after 30 minutes than DAN in the absence of Cu^(+2) ion. L-Lysine was found to be a competitive inhibitor and its K_i value was determined to be 0.12 mmole by Dixon plot.

백복령 , White Poria cocos , 중의 지방산 성분에 관한 연구
민태진,박상신,문순구 한국균학회 1987 韓國菌學會誌 Vol.15 No.1
The qualitative and quantitative analysis of fatty acids in the Korean White Poria cocos(Schw.) Wolf were performed. Dry powder of sample was extracted with chloroform-methanol(2 : 1, v/v) mixed solvent. The extract was saponified and methylated, and then analyzed by gas chromatography. Total 24 peaks were observed in the gas chromatogrom and 5 peaks i.e, C_(8:0) ; caprylic acid, C_(11:0) ; undecanoic acid, C_(12:0) ; lauric acid, C_(12:1), ; dodecenoic acid and C_(16:0) ; palmitic acid were identified. Major components were C_(8:0) and C_(12:1), and were determined as 6.657㎍/g and 10.176㎍/g respectively.
