Abstract:

Two new withanolides, named nicandrenone methyl ether (1), 26Snicandrenone methyl ether (2), together with ten known compounds were isolated from the whole plants of Nicandra physaloides (Solanaceae). Their chemical structures were deduced on the basis of spectroscopic analysis. Ten known compounds were identified as nicandrenone (3), Nic-7 (4), nicaphysalin E (5), pinosylvin monomethyl ether (6), 2S-pinocembrin (7), (1S, 2R)-1, 2-bis (4-hydroxy-3-methoxyphenyl)-1, 3-propanediol (8), vanillin (9), indole-3-carboxylic acid (10), vanillic acid (11) and drummondol (12).

Key words: Nicandra physaloides, Nicandrenone methyl ether, 26S-nicandrenone methyl ether, Withanolides
