摘要

Angiogenesis is essential for the growth and metastasis of most solid malignancies. Accordingly, tumor angiogenesis is an important pharmacological target for cancer prevention and treatment. This study was conducted to study antiangiogenic activity of some tropical plants. Seven plants were extracted successively with n-hexane and methanol to prepare 18 extracts and antiangiogenic properties of the extracts were studied by rat aorta ring assay. Nine extracts showed more than 50% inhibition of the blood vessels outgrowth from the primary tissue explants. The MTT assay was used to study the cytotoxic activities of extracts with more than 50% inhibition.
