Lignans from the Seeds of<i>Hernandia sonora</i>

Abstract

The seeds of HERNANDIA SONORA L. (Hernandiaceae) yielded eight lignans. Five of them have already been described from other species of the HERNANDIA genus, namely podophyllotoxin ( 1), picropodophyllin ( 2), deoxypodophyllotoxin ( 3), hernandin ( 4), and podophyllotoxin acetate ( 5). 5-Methoxypodophyllotoxin ( 6), 5-methoxypodophyllotoxin acetate ( 7), and a dibenzylbutyrolactone ( 8) are new. Their structures are presented in this publication.
