川藏香茶菜丁素和己素的结构确定

THE STRUCTURES ELUCIDATION OF ISODOPHARICIN D AND F

从川藏香茶菜中分离得到２个新化合物，经光谱解析和化学转换反应，确定川藏香茶菜丁素为３α，１１β，１３αｔｒｉｈｙｄｒｏｘｙｅｎｔｋａｕｒ１６ｅｎ１５ｏｎｅ（１），川藏香茶菜己素为１１β，１３α，１５αｔｒｉｈｙｄｒｏｘｙｅｎｔｋａｕｒ１６ｅｎ３αβＤｇｌｕｃｏｓｉｄｅ（２）。

Two new compounds were isolated from Isodon pharicus (Prain) Murata. Their structures were determined to be 3α,11β,13αtrihydroxyentkaur16en15one (1),named isodopharicin D, and 11β,13α,15αtrihydroxyentkaur16en3αβDglucoside (2), named isodopharicin F by chemical and spectral evidence.
