To authenticate Ayurvedic medicinal plants Ativisha (Aconitum heterophyllum) and Musta (Cyperus rotundus) at the raw drug source and in prepared herbal products, nrDNA ITS sequence based SCAR markers were designed and validated spp.-specific SCAR primers gave amplicon of 415 bp and 134 bp, respectively, in authentic species. The SCAR primers (Cyr-FP and Cyr-RP) could identify tissue sample containing 750 μg to 4.76 mg/100 mg of Musta in complex mixtures of DNA extracted from commercial herbal drugs. Ativisha could not be identified through SCAR markers suggesting that authentic species may not been used to prepare herbal drugs despite its being labelled as one of the ingredients in formulations. Analysis of individual tubers of Ativisha and Musta assures the presence of admixtures in raw drug trade of Ativisha, indicates the need to monitor the basic raw material supply and concludes, supplying plant materials through cultivation to manufacturing industries can minimize the risks of adulteration. © 2013 Elsevier Ltd.

Ethnobotany Research and Applications | Year: 2013
Herbs used by traditional healers for malaria management were documented in the Tumkur district of Karnataka, India. In total, 31 species of plants in 20 families were used. Thirty percent of the herbal remedies contained species in only three plant families: Fabaceae, Piperaceae, and Zingiberaceae. Leaves were the most commonly used plant part (29%). Eight plant species used in the study area were documented for the first time for their use in the treatment of malaria. Ethnomedical and antiplasmodial activity of documented species was assessed by comparison with published literature.
