Abstract

Abstract:

Phytochemical investigation of the leaves of Premna microphylla Turcz led to the isolation of 13 known compounds. Based on spectroscopic and chemical evidences, their structures were identified as diosmetin (1), blumenol A (2), (3S,5R,6S,7E,9R)-5,6-epoxy-3,9-dihydroxy-7-megastigmene (3), 3β-hydroxy-5α,6α-epoxy-7-megastigmen-9-one (4), ixerol B (5), (-)-dehydrovomifoliol (6), 3S,5R-dihydroxy-6S,7-megastigmadien-9-one (7), loliotide (8), (+)-dehydrololiolide (9), (+)-medioresinol (10), 4-oxopinoresinol (11), tormentic acid (12), and indole-3-carboxylic acid (13). Compounds 2–13 described above were isolated from this genus for the first time.
