ABSTRACT
The dichloromethane extract of the air-dried leaves of Ardisia cf. elliptica (subgenus Tinus) afforded a mixture of bauerenol (1a), α-amyrin (1b) and β-amyrin (1c). Their structures were identified by NMR spectroscopy. Mixtures of the triterpenes (1a-1c) at ratios of 2 : 2 : 1, 2 : 2 : 3 and 1 : 1 : 1 were tested for their angio-suppressive effects on duck chorioallantoic membrane (CAM). All three ratios were found to be effective in restricting inter-capillary length, while 1a-1c (2 : 2 : 1) was most effective in reducing branch point density with 100% CAM viability and embryo survivability, suggesting a high impact angio-suppressive potential of 1a-1c (2 : 2 : 1).
