The rhizome of Polygonatum robustum Nakai (Liliaceae) has been used as a crude drug for the purpose of tonic and thirst cure in Korea. The dried rhizomes were extracted with hot ether, then the residue was extracted with hot alcohol. 1) The three kinds of chemical constituents, substance, I, II and III were isolated by silicagel column chromatography from ether and alcohol extracts of the rhizomes. Substance I was confirmed as ${\beta}-sitosterol$, $C_{29}H_{50}O$ by mass and IR spectroscopy. Substance II was identified as stigmasterol by GLC. 2) Substance III was obtained by crystallization from the column chromatography of alcohol fraction. It was suggested as diosgenin based on chemical and spectral discussions. 3) The concentration of blood sugar was significantly decreased in the group administered the ether extract with 20% dextrose and adrenaline in comparison to that of 20% dextrose and adrenaline along.

Free and esterified sterols in neutral lipid fractionated from the free lipid of Korean white ginseng (Panax ginseng C.A. Meyer) were analyzed by TLC and GLC to investigate the contents and composition ratios. Content of each sterol was as follows: ${\beta}$-sitosterol was about 51.60 mg%, stigmasterol, 8.93mg% and campesterol, 2.17mg%. Fine root tended to have slightly higher contents of sterols than main root. Linoleic and palmitic acid as the major fatty acids in esterified sterols occupied 70% of the total composition.

The influence of extraction time on the fatty acid profile and the contents of calcium and magnesium in pig's shank were examined. The 9 kinds of fatty acid were identified in water extracts from pig's shank by GLC. The profiles of fatty acids from different extraction were similer to each other,. The content of linolenic acid was increased after two-hours extraction however the amounts of MUFA, PUFA and p/s ratio were decreased by the longer extraction time. The amount of calcium was 124.7mg% in raw materials but water extracts and bone powder samples showed higher values. in case of magnesium it was 138.4mg% in raw materials, but the extracts showed lower amount and bone powder exhibited higher values.

Attempts were made to investigate sterol components of Calvatia saccatum (Vahl.) Fr. which grows wildly in Korea. Its carpophores were collected in Gyeong Gi Province and extracted with chloroform and methanol. Two compounds were isolated from the extract and one of these compounds was identified as ergosterol by TLC, GLC and chemical tests.

제주산 밀감 juice의 향기성분을 질소 gas로 추출하여 gas liquid chromatography로 동정하였고 각 성분의 extraction coefficient를 사용하여 함량을 구하였다. 50여개의 peak중 26성분을 동정하였다. 향기성분중 ethanol이 140ppm이며 limonene이 120ppm으로 이 두 성분이 가장 중요한 성분으로 밝혀졌다.

포도주 발효에 사용되는 호모균주 12종을 Murphy배지에 배양하여 중간크기의 지방산(MCFA)의 생성을 분석하였고 발효조건에 따라 그 생성량을 관찰하였다. 특히 발효력이 강한 Saccharomyces cerevisiae에 속하는 균주들은 발효초기에 decanoic acid를 약 21-26mg/1 생성하였고 발효 후기에는 약 5-10mg/1로 감소하였다. 발효조건에서 볼 때 MCFA의 생성은 온도가 높을수록 감소하였고 당함량이 클수록 증가하였으며 또한 탄산가스의 존재 하에서도 증가하였다.

Attempts were made to investigate sterol components of Schizophyllum commune Fr. which is one of medicinal fungi and grows wildly in Korea. Its carpophores were collected in Mountain Gwanak and extracted with chloroform and methanol. A sterol was isolated and identified as ergosterol by TLC, GLC and chemical tests.
