CHEMICAL CONSTITUENTS OF THE STEM IN DALBERGIA SISSOO
The chemical constituents of ethyl acetate extracts from heartwood and sapwood of different ages of Dalbergia sissoowere studied by gas chromatography-mass spectrometry. The results showed that the chemical composition of wood heartwood and sapwood is significantly different. Inthe vertical direction, the type of the ethyl acetate extract from Dalbergia sissootends to decrease from the base to the upper portion; in the horizontal direction, the type of extract gradually decreases from the center to the periphery. And it showed an increasing trend with the age of the trees. The experiment also revealed that there were significant differences in chemical components between heartwood and sapwood. We speculated that the main chemical component trismethoxyresveratrol of heartwood extract may be related to the formation of heartwood, and the specific correlation needs to be further verified.
