本文报导威宁短柱油茶种予油中的脂肪酸、甾醇和三萜醇的分离、结构鉴定和测定.
The study of the fatty acids contents in Camellia weiningensis Li sp.nov(Theaceae)seed oil was carried out by using two analytical methods.The unsaponifiables of this oil were separated by silica gel column chromatography into four fractions.The present paper deals with the composition of triterpene alcohols,4-methylsterols and sterols.All these fractions were analysed by TLC and GLC their major mponents were identified by melting point determination,optical rotation,GLC,TLC,IR and MS a-Spinasterol,△7-stigmastenol,β-amyrin,germanicol,ψ-taraxasterol,tirucalladienol,butyrospermol and dammaradienol were isolated and identified.△7-Avenasterol,a-amyrin,citrostadienol and cycloeucalenol were identified.Trace quantities of△5-sterols were also separated by designed TLC on silica gel and cholesterol,campesterol,stigmasterol andβ-sitosterol were identified.No evidence of nonedibles was found in this oil.
