Abstract

The study was conducted to assess the phytochemical components and properties of herbal plant extracts, such as (a) sabungai (Gynura nepalensis DC), (b) pandan (Pandanus odoratissimus L.) and (c) tsaang-gubat (Carmona retusa (Vahl.) Masam.), as potential angiogenesis inhibitors using the Chick Chorioallantoic Membrane (CAM) assay. Phytochemical analysis showed that the three extracts were found to have alkaloids, tannins and flavonoids. Only pandan extract was assessed to contain anthraquinones and steroids. The treatments were individually compared to the positive control and negative control of the study. Statistical analysis showed significant difference on the mean number of branching points of eggs treated sabungai extract, pandan extract and tsaang-gubat as compared to negative control of the study. Sabungai extract was found significantly different to the positive control. On the other hand, no significant difference is seen in the mean number of the branching points of the eggs treated with pandan and tsaang-gubat extracts when individually compared to the positive control. Using the formula for CAM Vascularity that determines the inhibition properties of the extracts, it was found out that tsaang-gubat gained the highest inhibition of vascularity followed by pandan, then sabungai.
