RESUMEN
OBJECTIVE: To investigate the alkaloids from the stem of Artabotrys hainanensis. METHOD: Compounds in plant extracts were separated by silica gel and sephadex LH-20 column chromatography. Chemical structures were elucidated by chemical and spectral analyses including UV, 1H-NMR, 13C-NMR, ESIMS and ESI-MS-MS. RESULT: Eight alkaloids were isolated and identified as spinosine (1), 3-hydroxynornuciferine (2), juzirine (3), artabotrine (4), liridine (5), assimilobine (6), isococlaurine (7), N-demethylarmepavine (8). CONCLUSION: All alkaloids were isolated from this plant for the first time and compounds 1, 3, 7 and 8 were isolated from genus Artabotrys for the first time.

OBJECTIVE: To study the constituents of the essential oil from the leaves of Dalbergia odorifera T. Chen. METHOD: The constituent were separated and identified by GS-MS. RESULT: 21 compounds from the essential oil were identifed, which account for 77.71% of total volatile oils, 21.73% of 2-methoxy-4-vinylphenol, 13.97% of n-hexadecanoic acid, 6.69% of phenol. CONCLUSION: The study provided a chemical basis as a medicinal herb.
