Objective:The present study was carried out to investigate the phytochemical constituents,in vitro antioxidant potential and anthelmintic activities of Flacourtia sepiaria Roxb leaves.Methods:The dried powdered leaves of Flacourtia sepiaria were extracted using petroleum ether,chloroform,ethyl acetate and methanol by a soxhlet extractor and preliminary phytochemical screening was performed using standard protocols.All the extract was evaluated for their potential antioxidant activities using test such as DPPH,superoxide anion radical,hydroxyl radical,nitric oxide radical scavenging abilities,ferrous chelating ability and total phenolic and flavanoid content.Anthelmintic activity of extract was screened in adult Indian earthworm model.Results:Preliminary screening revealed the presence of bioactive compounds especially phenolics,tannins and terpenoids in all extracts.The phenolic and flavanoid content was highest in methanolic extract and lowest in petroleum ether extract.The paralytic(9.4610.212)and death time(31.43±1.148)of methanolic extract was found to be significant(P<0.05)when compared with paralytic(7.33±0.206)and death lime(18.60±0.229)of standard piperazine citrate at 100 mg/mL concentration.Conclusions:The results of the present study indicate that the leaf extracts of Flacourtia sepiaria exhibited strong antioxidant activity and possess significant anthelmintic activity and thus it is a good source of antioxidant and anthelmintic constituents. 展开更多

[目的]研究NaCl胁迫对簕仔树种子发芽及幼苗生长的影响。[方法]采用不同NaCl浓度(0、50、100、150、200、250 mmol/L)处理簕仔树种子,测定种子萌发和幼苗生长有关指标。[结果]种子萌发试验表明,簕仔树种子的发芽率、发芽势、发芽指数和活力指数在浓度≤50 mmol/L的NaCl溶液处理下与对照无差异;但当NaCl浓度>50 mmol/L时,处理组与对照组间表现出显著或极显著差异;当NaCl浓度达到250 mmol/L时,处理组种子萌发的各项指标降到最低。幼苗生长试验表明,NaCl浓度≤50 mmol/L时,对幼苗的生长未表现出不利影响,而当盐胁迫浓度>50 mmol/L时,根长、根茎比、鲜重及干重等指标值急剧降低,幼苗生长被抑制。簕仔树种子萌发时盐胁迫的适宜值、临界值和极限值分别为50、150、250 mmol/L。[结论]簕仔树具有一定的耐盐性。 展开更多
