Abstract
Heterostemma piperifolium is one of two species from the family Asclepiadaceae in Malaysia which can be found around Ipoh Limestone and Gunung Baling Kedah similarly it can be found around Taiping Hill and in the Batang Padang Valley areas. This work constitutes the first study of the alkaloids of Heterostemma piperifolium. In previous investigations on the stems of Heterostemma brownii new purinium and pyrimidine alkaloids were isolated. A phytochemical study of the stem of Heterostemma piperifolium has yielded three purinium alkaloids from the aqueous extract identified as 6-methoxy-7 9-dimethyl-2-dimethylarninopurinium chloride 1 6-methoxy-7 9-dimethyl-2-methylaminopurinium chloride 2 and 2-arnino-6-methoxy-7 9-dimethylpurinium chloride 3 on the basis of spectroscopic evidence.
