OBJECTIVE
To investigate the chemical constituents of Murraya kwangsiensis.
METHODS
Compounds were isolated by silica gel column chromatography and TLC method, respectively. Structures of compounds were elucidated by spectral (UV, IR, MS, 1HNMR and 13CNMR) analysis.
RESULTS
Five carbazole alkaloids and two other compounds were isolated and identified. Six of them are known compounds: murrayafoline A, murrayanine, koenine, isomahanine, palmitic acid and beta-sitosterol. One is a new alkaloid, named kwangsine.
CONCLUSIONS
A new alkaloid, named kwangsine, was isolated from Murraya kwangsiensis Var. Six known compounds were isolated from this plant for the first time.
