- Abstract
Phytochemical investigation of the aerial parts of Gymnema sylvestre led to the isolation of two known oleanane-type triterpenes, 1 and 3, five new acylated derivatives, 2, 4, and 5- 7, and a new lupane-type triterpene, 8. The structures and relative configurations of these compounds were elucidated by spectroscopic analyses, including 1D- and 2D-NMR spectroscopy and mass spectrometry, and by the comparison of their NMR data with those of related compounds.
