ABSTRACT
An ethnobotanical survey was carried out to collect the first-hand information on medicinal plants used by the inhabited and traditionally rich tribal communities (Chenchus, Yanadis and Nakkalas) in Chittoor district of Andhra Pradesh (AP) for the treatment of muscular pain and inflammation. The information was gathered by an integrated approach of botanical collections, group discussions and questionnaire. The survey revealed thirty forty (34) ethno-medicinal plants belonging to twenty one (21) angiospermic families specifically used for the preparation of medicinal remedies. The tribal claims on the medicinal plants are listed with Latin name, family, local name, part used, method of preparation, dose and its use in pain and inflammation conditions. The habit of frequently used plant were recorded includes tree species (44 %) followed by herbs (35 %) climbers (12 %), under shrubs (6 %) and shrub (3%). Most frequently utilized plant parts were leaves, followed by root, latex, whole plant, bark, fruits, rhizome and seeds. In this particular study the most dominant family was found to be Euphorbiaceae. The result clearly indicates that people living around Chittoor forest area hold valuable traditional knowledge of the use of medicinal plants for their primary health care need related to muscular injury and inflammation. These plant resources are important component in their local livelihood and to control overexploitation of these resources sustainable management approach and proper conservation strategy for the area is also highly recommended by bringing the involvement of local communities and forest department. More in-depth investigations on these claims through phytochemical and pharmacological parameters are required to explore their activities to deal with the conditions of pain and inflammation.
ABSTRACT
Background & objectives: Chittoor virus (CHITV) belongs to genus Orthobunyavirus, family Bunyaviridae. It has been isolated from various species of mosquitoes and pig from different parts of India. Five isolates of CHITV were characterized at the molecular level and compared with other Batai viruses (BATV) to find out any kind of reassortment in their genome. Methods: Complete nucelocapsid (S), glycoprotein (M) and partial RNA polymerase (L) segments of CHITV were amplified and sequenced. These sequences were compared with those of Batai viruses, isolated from different geographical locations in Asia, Africa and Europe. Results: Phylogenetic analysis revealed CHITV as a variant of BATV. High level of conservation was seen among the CHITV isolates studied. The CHITV sequences showed clustering in one lineage with the sequences from Japan and Malaysia, however, BATV sequences from Europe and Africa formed a separate phylogenetic lineage. Interpretation & conclusions: The study indicates the presence of a single genotype of CHITV circulating in India, despite the involvement of different hosts in the natural cycle by this virus. Analysis of the sequences of the S, M and L segments of genome indicated that the virus has not undergone any reassortment. This virus has not caused any epidemic involving humans, however, replication of the virus in different mosquito and vertebrate hosts species suggests that it is a cause of concern.
