Benzopyran derivatives from Melicope pteleifolia

Journal of Asian Natural Products Research
Phytochemical investigation of M. pteleifolia branches and leaves led to the isolation of seven benzopyran derivatives, including five new ones named melicopols A - E (2 - 6). The chemical structures were confirmed by extensive analysis of the 1D, 2D NMR, CD, and HR-QTOF mass spectra. The absolute configuration 1'S of leptol A (1) was firstly confirmed
