An Annotated Checklist of the Angiospermic Flora of Rajkandi Reserve Forest of Moulvibazar, Bangladesh
Bangladesh J. Plant Taxon. 25(2): 187-207, 2018 (December) © 2018 Bangladesh Association of Plant Taxonomists AN ANNOTATED CHECKLIST OF THE ANGIOSPERMIC FLORA OF RAJKANDI RESERVE FOREST OF MOULVIBAZAR, BANGLADESH 1 2 A.K.M. KAMRUL HAQUE , SALEH AHAMMAD KHAN, SARDER NASIR UDDIN AND SHAYLA SHARMIN SHETU Department of Botany, Jahangirnagar University, Savar, Dhaka 1342, Bangladesh Keywords: Checklist; Angiosperms; Rajkandi Reserve Forest; Moulvibazar. Abstract This study was carried out to provide the baseline data on the composition and distribution of the angiosperms and to assess their current status in Rajkandi Reserve Forest of Moulvibazar, Bangladesh. The study reports a total of 549 angiosperm species belonging to 123 families, 98 (79.67%) of which consisting of 418 species under 316 genera belong to Magnoliopsida (dicotyledons), and the remaining 25 (20.33%) comprising 132 species of 96 genera to Liliopsida (monocotyledons). Rubiaceae with 30 species is recognized as the largest family in Magnoliopsida followed by Euphorbiaceae with 24 and Fabaceae with 22 species; whereas, in Lilliopsida Poaceae with 32 species is found to be the largest family followed by Cyperaceae and Araceae with 17 and 15 species, respectively. Ficus is found to be the largest genus with 12 species followed by Ipomoea, Cyperus and Dioscorea with five species each. Rajkandi Reserve Forest is dominated by the herbs (284 species) followed by trees (130 species), shrubs (125 species), and lianas (10 species). Woodlands are found to be the most common habitat of angiosperms. A total of 387 species growing in this area are found to be economically useful. 25 species listed in Red Data Book of Bangladesh under different threatened categories are found under Lower Risk (LR) category in this study area. -

The plant extracted with different organic solvents viz., aqueous, chloroform and ethanol. Antifungal activity of the leaf extract against some K e yw or ds pathogenic fungus like Aspergillus nigar, Pencillium notatum, Rhizhotonia solani and Colletotrichum falcatum. The inhibitory effect of leaf distillates was compared with the Antifungal activity standard fluconazole. Quantitative phytochemical analyses were performed using standard Fabaceae procedures. The ethanol leaf extracts of P. pulchellum showed maximum activity against Phyllodium pulchellum Aspergillus niger, followed by Colletotrichum falcatum, Penicillium notatum and Phytochemicals Rhizoctonia solani. The ethanolic extract showed higher level of phenol (88.68±2.081 mg/g), flavonoid (71.33±4.172 mg/g) tannin (30.23±3.025 mg/g) and than the other extracts which having secondary metabolites. These findings provide scientific evidence to support the traditional use of Phyllodium pulchellum and also indicate that the leaf of this species are a promising potential for the development of quantitative phytochemical and antifungal agent. -

College, Dibrugarh - 786 001 (Assam), India. E-mail: [email protected] Abstract Changes in botanical names of flowering plants are an issue which comes up from time to time. While there are valid scientific reasons for such changes, it also creates some difficulties to the floristic workers in the preparation of a new flora. Further, all the important monumental floras of the world have most of the plants included in their old names, which are now regarded as synonyms. In north east India, “Flora of Assam” is an important flora as it includes result of pioneering floristic work on Angiosperms & Gymnosperms in the region. But, in the study of this flora, the same problems of name changes appear before the new researchers. Therefore, an attempt is made here to prepare an updated account of the new names against their old counterpts of the plants included in the first two volumes of the flora, on the basis of recent standard taxonomic literatures. In this, the unresolved & controversial names are not touched & only the confirmed ones are taken into account. In the process new names of 470 (four hundred & seventy) dicotyledonous plant species included in the concerned flora are found out. Key words : Name changes, Flora of Assam, Dicotyledonus plants, floristic works. -

The experiments were performed under constant light (ca. 500 lux) and temperature (about 20 °C) conditions. The period of the leaflet was then around 5 min. Leaflets moving up and down in a magnetic field of approximately 50 mT flux density increased the period by about 10% due to a slower motion in the “up” position.

In Silico Analysis of Phytochemicals from Coffea Arabica Against
In Silico Analysis of Phytochemicals From Coffea arabica Against Haemophilus influenzae Causing Conjunctivitis ABSTRACT: Phytochemicals are secondary metabolites obtained from plants through various metabolic pathways . It has been reported that Coffea arabica plant extract is used to cure conjunctivitis. The plant extract contains different phytochemicals. Conjunctivitis is caused by Haemophilus influenzae. One of the key enzymes involved in its biochemical pathway is shikimate dehydrogenase. The molecular docking of the phytochemicals with the enzyme was studied using Biovia Discovery Studio. The strength of the interaction was evaluated based on -CDocker energy and -CDocker interaction energy. High positive values for both the parameters indicated that out of different phytochemicals ,caffeine and cholorogenic acid can effectively deactivate the shikimate dehydrogenase enzyme thereby interrupting the life cycle of Haemophilus influenza. KEY WORDS: Phytochemical, Biovia, Discovery studio, Coffea arabica,Haemophilus influenzae. 1. INTRODUCTION: The faster and developed life styles affects the health of an individual. Now a day’s lifestyles are an important factor for health. According to WHO 60% health factor directly related with way of living [1]. Millions of people follow unhealthy lifestyle like unhealthy diet, smoking, alcohol consuming, drug abuse, stress and so on. Hence, they are encountered with illness, disability and problems like joint pain, cardiovascular disease, hypertension, overweight, skin lesions, low vision and low hearing problems in early age. A little change in way of living can prevent these diseases from annexing our society [2]. Vagbhatta's Astangahrdayam gives information about how plants are used for curing disease [3].Medicinal plants are the major constituents of indigenous natural medicine, modern medicine, food supplements, bioactive principles, pharmaceutical intermediates and synthetic drugs [4].Medicinal plants are used for the preparation of drugs from Sumerian clay slab from Nagpur approximately 5000 years old.
