SUMMARY

The plants are a great source for the discovery of new products of medicinal value for the development of drugs. Several chemical products derived from plants are important drugs that are currently used in one or more countries of the world. In this study, we performed a GC-MS analysis on a fraction of the hexane extract from the leaves of Cissus incisa, an endemic plant from Mexico and the southern of The United States. Until the best of our knowledge there are not reports about the phytochemical composition of this plant. As a result of the analysis, five sterols were identified. The stigmastan-3, 5-diene was the most predominant with 74% of the abundance. It has been found that these different active phytochemicals possess a wide range of biological activities.
