Abstract

Clerodendrum is a member of Lamiaceae family; mostly they are perennial shrubs and in Indian Ayurvedic system they are used in many of the herbal preparations. Species of Clerodendrum are distributed in tropical regions of Asia including India, Myanmar, Bangladesh, Malayasia, Indonesia, Thailand, Bhutan, Nepal and also in temperate Tibet. Moreover, the medicinal properties of the species are attributed to their phytochemical constituents that are believed to cure varied ailments. Although, ethnobotanically, they have diverse medicinal properties but there is no sufficient information illustrating the comprehensive genetic variation among the different medicinal species of Clerodendrum. Hence, an initiative was undertaken to discriminate the genetic variations among 11 important species of Clerodendrum through DNA barcoding techniques. The DNA barcode analysis by means of matK, Rps16 and TrnL-F clearly reflected that two subfamily Symphorematoideae and Nepetoideae very close to Ajugoideae which validates the traditional classification of Cronquist.
