Chemical Constituents from Artificially Induced Dragon's Blood of Dracaena cambodiana

Abstract:

In order to understand the chemical constituents of artificially induced dragon's blood of Dracaena cambodiana, ten compounds were isolated from the ethanol extract. On the basis of spectral data, their structures were indentified as socotrin-4'-ol (1), homoisosocotrin-4'-ol (2), (E)-3-(3,4-dihydroxybenzylidene)-7-hydroxy- chroman-4-one (3), 5-hydroxy-7-methoxy-3-(4'-hydroxybenzyl)-4-chromanone (4), 3-deoxysappa­nchalcone (5), sappanchalcone (6), 7,4'-dihydroxyflavone (7), 7,4'-dihydroxy-8-methylflavone (8), syringares­inol (9) and bis (2-ethylhexyl) phthalate (10). All compounds were isolated from artificially induced dragon's blood of Dracaena cambodiana for the first time, compound 8 was a new natural product, compounds 3-6 were isolated from dragon's blood for the first time. The compounds 7 and 8 had inhibitory activities against methicillin-resistant Staphylococcus aureus (MRSA).
