Abstract/ Executive Summary:

Background: The flowering plants have a number of uses as food, specifically as grains, sugars, vegetables, fruits, oils, nuts, and spices. In addition, plants and their products serve a number of other needs, such as dyes, fibers, timber, fuel, medicines, and ornamentals. The contribution of the angiosperms to biodiversity and habitat is so extremely important that human life is totally dependent on it. Materials and Methods: Angiosperm diversity at village Sabgram of Bogra district, Bangladesh conducted during March 2013 to July 2014. All the species were noted and time to time the areas were visited to see when they flowered. For the morphological study, different types of species were examined again and again in order to see if there was any variation or not. They were collected at flowering stages and herbarium specimens were prepared as vouchers. In this practice standard method was followed. Results: A total of 196 species belonging to 160 genera under 69 families were recorded. One hundred nineteen (119) medicinal plants have been recorded with their uses for the cure of more than 87 diseases, and some of these are skin disease, diarrhea, dysentery, fever, earache, piles, inflammations, rheumatism, dyspepsia, constipation, diabetes, kidney disease, bronchitis, ulcers, anemia, asthma, ringworm, herpes, jaundice, headache, opthalmia, cough, eye disease leprosy, menstrual disease and others. Conclusion: The present study was made an inventory of the angiosperm diversity in the study area and documentation of long-established knowledge on the medicinal uses of these plants is essential for conservation efforts for the plants resources and new drug development.

End Date: 00-07-2014

Program Area: Conservation and Biodiversity

Commodity: Plant

Objectives:

The present study was made an inventory of the angiosperm diversity and medicinal uses at the village Sabgram of Bogra, Bangladesh.

Methodology:

Study area: Sabgram village is situated at 24°51'34.7"N and 89°24'01.9"E. The village lies about for 3 Kilometers East of Bogra city. It is situated in the North-East side of Dhaka-Bogra highway road, near the Bogra bypass road-2, South of Matidali bus stand and west side of Gabtoli. The climate of Sabgram village is characterized by hot, humid summers and generally mild winters and rainfall. The summer season commerce early in the March with the cessation of the Northerly wind. The winter season (November-January) which is cool and little rainfall; summer season (June-October) which is warm and no rainfall. In terms of temperature variation it appears that average annual temperature is about 26-36. The maximum monthly temperature can reach up to 40.1 during May and minimum monthly temperature 9° C during January [8]. Methodology: Angiosperm diversity at the village of Bogra sadar, Bangladesh was carried out from March 2013 to July 2014. A total of 196 species belonging to 160 genera under 69 families were collected and identified. A survey on the determination of the location of different species was made and a list was prepared to be acquainted with the plants available in the selected area. All the species were noted and time to time the areas were visited to see when they flowered. For the morphological study, different types of species were examined again and again in order to see if there was any variation or not. They were collected at flowering stages and herbarium specimens were prepared as vouchers. In this practice standard method was followed. In this regard different types of plant species were collected from different habitats. All the collected plant specimens were kept in the Herbarium, Department of Botany, and University of Rajshahi, Bangladesh. Plant Identification: The major collected materials were identified and described up to species with the help and were consulted. For the current name and up-to-date nomenclature and were also consulted.

Achievement/Findings:

Angiosperm diversity at the village Sabgram of Bogra district, Bangladesh conducted during March 2013 to July 2014. A total of 196 species belonging to 160 genera under 69 families were recorded. Amaranthaceae, Asteraceae, Apocynaceae, Caesalpiniaceae, Convolvulaceae, Cucurbitaceae, Euphorbiaceae, Fabaceae, Moraceae, Malvaceae, Mimosaceae, Myrtaceae, Poaceae, Rutaceae and Solanaceae are the dominant families with high species diversity. A total of 119 medicinal plant species belonging to 109 genera and 50 families were collected and recorded for their use in 142 ailments. Most of the local people in the study area are poor are illiterate. In one hand, these people are out of the reach of modern medicines and on other hand, the market price of most available medicines are very expensive. As a result, these medicinal plants are used by them to cure following the diseases, especially for asthma, cough, constipation, dysentery, diarrhea, diabetes, earache, fever, headache, jaundice, menstrual disease, piles, skin diseases, vomiting, worm, wound and others. The study also suggested that the present information on medicinal use of plants by tribal people may be used for botanical and pharmacological research in future for the discovery of new sources of drugs.
