Abstract
A method for compound identification based on mass fragmentation patterns was developed to distinguish known oligostilbenes directly in crude plant extracts. Eleven pure oligostilbenes were used as standard compounds, and a pilot database of MS data was established. Seven extracts from Dipterocarpaceous plants; three from Neobalanocarpus heimii, three from Dryobalanops spp. and one from Dipterocarpus semivestitus were used as test materials. Eleven compounds were positively identified in the heartwood extract, nine in the bark, and six in the leaves of Neobalanocarpus heimii, one compound each in Dryobalanops lanceolata, D. rappa and D. aromatica, as well as two in Dipterocarpus semivestitus extract. Identification of all compounds were performed within a short analysis time.
