Background: Curculigo recurvata(C. recurvata) is an enthnomedicinally important herb reported to have significant medicinal values. The present study aimed to explore the in vivo and in silico anti-nociceptive and anti-diarrheal effects of a C. recurvate rhizome methanol extract(Me-RCR).Methods: The analgesic effects of Me-RCR were assessed using acetic acid-induced writhing and the formalin-induced flicking test. The drugs were administered intraperitoneally(IP) at doses of 200 and 400 mg/kg body weight(bw). Anti-diarrheal activity was evaluated by assessing intestinal motility, hypersecretion, and fecal score in mice at oral doses of 200 and 400 mg/kg·bw. Computer facilitated analyses for anti-nociceptive and anti-diarrheal activities of three isolated compounds from C. recurvata were undertaken to identify the best-fit ***: The Me-RCR showed significant(P <.05) peripheral anti-nociception at the highest dose. The extract inhibited both early and late phases of nociception in the formalin-induced writhing test. In the castor oil-induced diarrhoea model, the extract significantly(P <.05) prolonged the onset time of diarrhoea, inhibited percentage of diarrhoea, and decreased both the volume and weight of intestinal contents. Rates of intestinal fluid accumulation inhibition were(33.61 ± 1.00)% and(46.44 ± 0.89)% at Me-RCR doses of 200 and 400 mg/kg·bw, respectively. Moreover, a significant(P <.05) reduction in gastrointestinal motility was observed. An absorption, distribution, metabolism, excretion and/or toxicity(ADME/T) test showed that the selected compounds yielded promising results, satisfying Lipinski's rule of five for predicting drug-like potential. Notably, of the three phytoconstituents curculigine and isocurculigine possessed the highest affinity for the COX-1 and COX-2. Isocurculigine was also identified as the most effective anti-diarrheal compound in the computer-facilitated ***: An extract of the plant C. recurvata

Objective:To examine hypoglycemic and antibacterial activity against some Gram-positive and Gram-negative bacteria of organic extracts of four Bangladeshi ***:An in vivo hypoglycemic effect on mice model was used to check the hypoglycemic effect of four Bangladeshi herbal organic extracts viz.,roots of Curculigo recurvata ***(Satipata)(***),leaf of Amorphophallus bulbifer Roxb.(Olkachu)(***),whole plant of Thunbergia grandiflora Roxb.(Nillata)(***)and leaf of Steudnera colocasiifolia ***(Yunnan)(***)using glibenclamide as a positive control and water as a negative *** were also tested for antibacterial activity on three Grampositive and four Gram-negative bacteria by disk diffusion ***,*** and *** were extracted with methanol and *** was extracted with ***:Among all the plant extract,only ethanol extract of *** leaves at 800 mg/kg dose significantly(P<0.01)reduced fasting glucose level in normal mice as compared to standard drug glibenclamide(5 mg/kg).Ethanol extract of *** leaves at 800 mg/kg dose decreased 20.28%of blood glucose level after 2 h of administration in normal mice,where glibenclamide decreased 39.63%.Methanol extract of *** didn’t show any zone of inhibition against the tested bacteria,but other three extracts showed a wide range of zone of ***,none of the extract showed antibacterial activity against all the tested *** extract of *** showed maximum zone of inhibition against Bacillus cereus[(10.50±0.50)mm],Salmonella typhi[(16.20±1.26)mm],Escherichia coli[(13.00±1.00)mm]and ethanol extract of *** showed maximum zone of inhibition against Staphylococcus aureus[(11.20±1.26)mm],Bacillus subtilis[(12.00±0.50)mm],Salmonella paratyphi[(10.80±0.29)mm].Only methanol extract of *** showed(8.50±0.50)mm and(7.20±0.76)mm zone of inhibition against P

Objective:To estimate the antidepressant,anxiolytic and antinociceptive activities of ethanol extract of Steudnera colocasiifolia ***(***)***:Swiss albino mice treated with 1%Tween solution,standard drugs and ethanol extract of ***,respectively,were subjected to the neurological and antinociceptive *** tail suspension test and forced swimming test were used for testing antidepressant activity,where the parameter is the measurement of immobility *** activity was evaluated by hole board ***-nociceptive potential of the extract was also screened for centrally acting analgesic activity by using formalin induced licking response model and acetic acid induced writhing test was used for testing peripheral analgesic ***:Ethanol extract of *** significantly decreased the period of immobility in both tested models(tail suspension and forced swimming models)of antidepressant *** the hole board model,there was a dose dependant(at 100 and 200 mg/kg)and a significant increase in the number of head dipping by comparing with control(1%Tween solution)(P<0.05 and P<0.001).In formalin induced licking model,a significant inhibition of pain compared to standard diclofenac sodium was observed(P<0.05 and P<0.001).In acetic acid induced test,there was a significant reduction of writhing response and pain in mice treated with leaves extract of *** at 200 mg/kg body weight(P<0.05 and P<0.001).Conclusions:The results proofed the prospective antidepressant,anxiolytic and antinociceptive activities of ethanol extract of *** leaves.
