Isolation and structure determination of compounds from ethyl acetate extract of Chukrasia tabularis
Tạp chí Khoa học(2022)
摘要
From an ethyl acetate extract of the barks of Chukrasia tabularis, three compounds including one limonoid (tabularisin A), one flavonoid (quercetin), and one coumarin (scopoletin) were isolated by chromatographic methods. Their structures were comfirmed by analysis of spectroscopic data (ESI-MS, 1H-NMR, 13C-NMR, DEPT, HMBC, HSQC và COSY) and by comparison with the literature reports.
