Traditional Coconut Farming in the Rural Landscape of Meghna Floodplain in Bangladesh
Miah, Md. Danesh,Islam, Mohammed Ohidul,Hossain, Md. Aktark,Shin, Man Yong Korean Society of Forest Science 2005 한국산림과학회지 Vol.94 No.5
An exploratory survey was performed to assess the present status of distribution and production of coconut palm (Cocos nucifera Linn.) in the rural landscape of Meghna floodplain of Bangladesh. A multistage simple random sampling technique was adopted to identify the study area and respondents. A total of 50 households were selected randomly for the study. Traditional knowledge on cultivation, management, and production of coconut palm was emphasized. Marketing of coconut palm products and income derived from coconut palm cultivation was taken into consideration. Perceptions of farmers, traders and professionals were described in due context of opportunities and constraints of coconut palm cultivation. Coconut palm cultivation was found to play an important role in household economy in rural Bangladesh sharing considerable contribution to the total income. About 10% of their total annual income was reported to come from coconut husbandry. Highest number of the coconut palms, 24%, was found to grow in the homestead compounds and in the pond banks. About one-third lands of the households were found to be covered by the coconut palms. Maximum, 19%, coconut palms were found in the 16-20 years age-class. Production of coconut was found highest at the age-class 11-15 years. The study found some important opportunities and constraints of coconut farming in rural Meghna floodplain area of Bangladesh. The results of this study would be useful for the rural development practitioners in Bangladesh.

Bioactivities of leaf and root extract of Ceriscoids turgida (Roxb.)
Md. Nazmul Hasan Zilani,Nazneen Ahmeda Sultana,Monjurul Kader Bakshi,Israt Jahan Shampa,Samia Jaman Sumi,Ohidul Islam 경희대학교 융합한의과학연구소 2018 Oriental Pharmacy and Experimental Medicine Vol.18 No.2
In traditional medicine leaf and root of Ceriscoides turgida (Roxb.) are commonly used to treat indigestion in child, leucorrhoea, dog bite, snake bite, scorpion string, epilepsy, stomachache and a number of ailments. The present study was carried out to investigate antioxidant, analgesic, antibacterial and cytotoxic activities of methanol extract of leaves and roots of C. turgida. Total flavonoids content was spectrophotometrically determined using aluminum chloride colorimetric assay while total phenolic and tannin content by Folin Chiocalteu’s reagent. Antioxidant activity was determined by DPPH free radical scavenging and reducing power assay. Analgesic activity was assessed by acetic acid induced writhing method. Antibacterial activity was evaluated by disc diffusion assay while brine shrimp lethality bioassay was carried out to verify the cytotoxic potential. Root extract contains greater amount of total phenolic (79.99 mg GAE/g dry extract) and flavonids content (35.27 mg QE/g dry extract) in comparison to leaf extract (30.75 mg GAE/g and 25.93 mg QE/g dry extract respectively). Root extracts showed DPPH scavenging (157.45 μg/mL) that was comparable to standard ascorbic acid (14.15 μg/mL). Reducing power of root extract was prominent than leaf extract in comparison to ascorbic acid. Both extract showed significant (P < 0.01) analgesic activity. In disc diffusion assay leaf extract showed greater antibacterial activity than root extract. Furthermore, extracts showed moderate cytotoxic effect. The present study demonstrates that methanol extract of C. turgida leaf and root has significant antioxidant and analgesic effect. The extracts also showed moderate antibacterial and cytotoxic activities.
