An inventory of angiosperm flora of Satchari National Park, located in Habiganj district, is prepared on the basis of collected materials and observation made from November 2008 to December 2009. From the study site, 245 angiosperm species including cultivated and planted in 183 genera under 72 families are documented. Of 245 species recorded here, 86 species are represented by herbs, 46 by shrubs, 73 by trees, 37 by climbers and 3 by epiphytes. The survey has also confirmed the occurrence of seven threatened angiosperm species, one tree fern and one gynosperm in the Park area. For each species scientific name, local name (wherever available), family, habit and habitat are provided with citation of specimens.

The methanol extract of Corypha taliera fruits as well as its n-hexane, carbon tetrachloride, dichloromethane and aqueous soluble fractions were subjected to screening for antioxidant, antimicrobial and cytotoxic activities. The methanolic crude extract exhibited the highest antioxidant activity (IC(50) 19.33 mu g/ml as compared to 9.5 mu g/ml for the standard agent, BHT). The crude methanol extract and its carbon tetrachloride, dichloromethane and aqueous soluble fractions showed mild to moderate inhibition of microbial growth against some of the tested organisms. All the extractives exhibited strong cytotoxic properties, among which the methanol extract revealed the strongest cytotixicity (LC(50) = 0.43 mu g/ml).

... During an investigation on the voucher specimens of Lauraceae housed in local herbaria of Bangladesh, two specimens of this family that were previously collected from the Cox's Bazar and Rangamati districts and preserved in the Bangladesh National Herbarium (DACB) and Bangladesh Forest Research Institute Herbarium (BFRIH), respectively, and two other specimens that were collected from the Lithitila forest area of Juri, Moulvibazar, during the floristic surveys carried out in the northeast region of Bangladesh in 2022-2023, seemed to be distinct from all of the 66 species under 14 genera of this family reported so far from Bangladesh (Das and Alam, 2001;Ara et al., 2007;Arefin et al., 2011;Ara and Khan, 2015;Basak and Alam, 2015;Rahim, 2019;Rahman et al., 2024). These specimens did not match with the voucher specimens or the taxonomic description or key characters of any species of Lauraceae known or reported so far from Bangladesh. ...

... The free radical scavenging activity of the plant extractives was determined on thestable radical produced by 1,1diphenyl-2-picrylhydrazyl (DPPH) [19,20] . A. dichotoma significantly scavenged the free radicals generated by DPPH to demonstrate its antioxidant activity [21] . ...

... Therefore this species has been reported here as a rediscovery for Bangladesh. Though rediscovery is not a routine taxonomic work, occasionally taxonomists had have to rediscover the previously published taxa that could not be located since many years to confirm their present occurrence and exact distribution (Ardiyani et al., 2011;Uddin et al., 2011;Yeo et al., 2012). These specimens are presently deposited at Jahangirnagar University Herbarium (JUH). ...
