3종(種)의 가지과(科) 식물중(植物中)의 sterol조성(組成)을 TLC, GLC 및 GLC-MS에 의(依)해서 분석(分析)하여 4-desmethylsterol fraction에서 7종(種), 4-monomethylsterol fraction에서 9종(種), 그리고 4.4-dimethylsterol fraction에서는 8종(種) 모두 24종(種) sterol을 동정(同定)하였고, 이들 sterol들이 식물체내(植物體內)에서 어떤 생합성경로(生合成經路)를 거치는가를 검토(檢討)하였다.
Sterol compositions of three solanaceous plant seed oils i.e., tobacco(Nicotiana tabacum L.), datura (Datura stramonium L.) and Chinese lycium (Lycium chinense Mill.) were analyzed by thin layer chromatography, gas liquid chromatography and gas liquid chromatography-mass spectrometry. Cholesterol, cholest-7-enol, campesterol, 24-methylenecholesterol, stigmasterol, sitosterol, and 28-isofucosterot were identified in 4-des-methylsterol fraction. 31-Norlanost-8-enol, $4{alpha}$-methylcholest-8-enol, lophenol, 31-norlanosterol, obtusifoliol, 31-norcycloartenol, cyloeucalenol, gramisterol (24-methylenelophenol), and citrostadienol in 4-monomethylsterol fraction, and lanost-8-enol, cycloartanol, lanosterol, ${eta}$-amyrin, 24-methylenelanost-8-enol, cycloartenol, lupeol and 24-methylenecycloartanol in 4,4-dimethylsterol fraction were identified respectively.
