Abstract
From the resinous exudate of Heliotropium sinuatum eight flavonoids we re isolated: 5,7,4'-trihydroxyflavanone (naringenin) 1, 5,3',4'-trihyd roxy-7-methoxyflavanone (7-O-methyleriodictyol) 2, 3-acetoxy-5,7-dihyd roxyflavanone (pinobanksin-3-acetate) 3, 5,7-dihydroxyflavanone (pinoc embrin) 4, 5,7,3'-trihydroxy-4'-methoxyflavanone (hesperetin) 5, 5,7-d ihydroxy-3-methoxyflavone (3-O-methylgalangin) 6, 5,7,4'-trihydroxy-3- 3'-dimethoxyflavone (3-O-methylisorbamnetin) 7 and 5,4'-dihydroxy-3,7, 3'-trimethoxyflavone (pachypodol) 8. Geranyl phenolic compounds were n ot found in the resinous exudate.
