摘要

再從事台灣紅豆杉心材成分單離及分析之結果，除了得到數種已發現之化合物長鏈烷、長鏈酯、β-sitosterol; taxusin; taxa-4(20), 11-diene-5α,9α,10β-diacetate; taxa-4(20), 11-diene-2α,5α,7β,10β-tetrol-5α,7β,10β-triacetate-2α-α- methylbutyrate; secoisolariciresinol及isotaxiresinol; 1-dehydroxybaccatin IV, (+)-dihydroquercetin，另外得到四種在台灣紅豆杉中未被發現之化合物，即d-sesamin; 4-hydroxy-sesamin; cis-terpin; 1,4-p-menthanediol，此化合物是第一次於天然物中分離出之化合物。
