Abstract/ Executive Summary:

The study recorded the medicinal plant diversity and their uses in two selected villages of Mymensingh district using a random stratified homestead survey. A total of 2067 medicinal plants have been recorded under 95 species, 78 genera and 49 families comprising 29.27% of the total plant populations in the Bhabkhali village. The plants contained 176 of herbs, 983 of shrubs, 655 of trees and 253 of climbers. In Dori Bhabkhali village, a total of 2375 plants were listed under 77 species, 65 genera and 44 families comprising 26.63% of the total plant populations. The plants contained 176 plants of herbs, 1117 of shrubs, 822 of trees and 260 of climbers. The highest Prevalence Value (PV) found in Aphanimixis polystachya in both the villages (95% and 87%). The highest species diversity (H) was observed in Aphanamixis polystachya (0.1475) in Bhabkhali village and in Dori Bhabkhali village, the greater species diversity (H) was found in Operculina turpethum (0.1194). Plant parts such as leaf, root, stem, flower, bark, seed, fruit, tuber, kernel or even whole plants were used for medicinal purposes by the rural peoples.

Keywords: Diversity, Prevalence value, Medicinal uses

Location: Bhabkhali union of Sadar Upazila under Mymensingh district

Start Date: 00-01-2006

End Date: 00-12-2006

Program Area: Development of Host and Medicinal Plants

Non-commodity: Adoption of technology

Objectives:

1. To compare distribution, abundance and diversity of medicinal plant genetic resources in two selected villages and to provide an inventory of homestead medicinal plant species with particular emphasis on its medicinal uses.

Methodology:

The Mymensingh district lies between 24⁰15′ and 25⁰12′ north latitudes and between 90⁰13′ and 90⁰49′ east longitudes. The study was carried out in two villages of Bhabkhali union of Sadar Upazila under Mymensingh district. The villages are Bhabkhali and Dori Bhabkhali. Initially 20 days were spent to select the village and households by observing the status of medicinal plants (tree, shrub, herb and climber) and indigenous knowledge of using these species. Structured questionnaire was used to study the socio economic and biological parameters of the home garden. Then questionnaire was pre-tested (before starting the actual survey) with 100 households in order to make necessary modifications. The sample responded for the study consisted of 80 households, 40 from each village. Most of the information was obtained through interviews of household members. Identification of the existing medicinal plants was done by the help of rural people, local traditional doctors and with the help of taxonomic books. The data collected from the study area were entered in the computer to prepare a database through Microsoft Excel database programme. Then the data were quantitatively analyzed for relative frequency, relative density and abundance following Curtis and Mclntosh. The relative values for frequency and density were determined. Percent of area containing a particular species is one of the indicators of the prevalence of species of that particular species in the area. Population of species per unit area is divided by farm with the species and then multiplies with 100 to get the prevalence value (PV). The species diversity (H) was determined by using Shannon-Wiener information index.

Achievement/Findings:

The highest species diversity (H) was observed in Aphanamixis polystachya (0.1475) in Bhabkhali village and in Dori Bhabkhali village, the greater species diversity (H) was found in Operculina turpethum (0.1194). Plant parts such as leaf, root, stem, flower, bark, seed, fruit, tuber, kernel or even whole plants were used for medicinal purposes by the rural peoples.
