The study is aimed at development of Physicochemical parameters and to investigate the active principle present in Pavonia zeylanica Cav. (Malvaceae) commonly known as Ceylon Swamp Mallow and in Kannada it is called as Topala, Balarakshasi, and Antutogari. The Ceylon Swamp Mallow is a profusely branched, bristly, large herb, growing up to 1-1.5 m tall. The Plant extract is used for vomiting, vermifuge, oliguraia, tumours and fever. Therefore, from extensive literature survey it was revealed that no reports were available on chemoprofile of Pavonia zeylanica to check the identity and purity of the drug. The present work embodies the investigations carried out to establish methods for quality control of drugs as per WHO guidelines: physico-chemical parameters like Loss on Drying, Extractive values, Foaming index, Ash values and to investigate the phytochemical present in the extracts in the preliminary level were also carried out for the quality control of the drug. Thus it was thought worthwhile to explore this plant on the basis of its standardization parameters. The study will provide referential information for the correct identification of the crude-drug.
