Chemical Constituents of Chinese Agarwood Induced by Artificial Holing

Abstract:

In order to understand the chemical constituents of Chinese agarwood induced by artificial holing, eight compounds were isolated from its ethyl acetate extract. On the basis of spectral data, they were identified as 5-hydroxy-7,4'-dimethoxyflavone (1), benzenepropanoic acid, 3-hydroxy-4-methoxy-methyl ester (2), zingerone (3), p-methoxy phenylpropionic acid (4), n-dotriacontanol (5), (20R)-24-ethylcholest-4-en-3-one (6), ergosta- 4,6,8(14),22-tetraene-3-one (7), stigmasterol (8). Compounds 1, 2, and 4-8 were isolated from agarwood for the first time. Compound 3 had inhibitory activities against to Staphylococcus aureus and Ralstonia solanacearum, while compound 7 only to R. solanacearum.
