On the Seed Oils from Aphananthe aspera, Viburnum awabuki, Actinostemma lobatum, Coreopsis tinctoriaand Taraxacum albidum

Abstract

The characteristics of seed oils from A. aspera, V, awabuki, A. lobatum, C. tinctoriaand T. albidum were investigated. Each oil was obtained by extraction from the dried seeds with ether, , followed by treating with n-hexane. The characteristics of seed oils (Table-1) and fatty acid compositions by GLC (Table-2) were investigated. In order to examine the glyceride compositions in seed oils, the purified triglycerides obtained by TLC were hydrolyzed into, β-monoglyceride by the action of pancreatic lipase. The β-monoglyceride separated by TLC was esterified into methyl ester with 0.2 N-sodium methoxide solu. to examine the composition of fatty acids in 2-position of triglyceride by GLC (Table-2). Triglcyeride compositions in seed oils were also calculated (Table-3)
