Phytochemical compounds from leaves and bark of Beilschmiedia Kunstleri gamble

The phytochemical studies on one species of Lauraceae family; Beilschmiedia kunstleri Gamble have been performed. The phytochemical study involves extraction using Soxhlet extractor, isolation by using various chromatographic methods such as column chromatography, thin layer chromatography and higher performance liquid chromatography and the structural elucidation of the isolated compounds was established on the basis of extensive spectroscopic studies including UV, IR, CD, OR, 1D-NMR (1HNMR, 13C-NMR), 2D-NMR (1H-1H COSY, NOESY, HMQC/HSQC and HMBC) and MS. Seven compounds which consist of six alkaloids, in which four aporphines, one benzylisoquinoline and one morphinandienone, and one neolignan were isolated from the leaves of Beilschmiedia kunstleri Gamble, whereas the bark yielded nine compounds which consist of seven alkaloids, one neolignan and one dienamide.
