Reduction Of Pain

Ampelocissus barbata (Wall.) Planch. is a native medicinal herb in Bangladesh. The present study was aimed at exploring the phytochemical compositions and analgesic potential of the plant in vivo. The methanol extract of A. barbata along with its different fractions were subjected to phytochemical evaluation through established chemical tests for ascertaining the available pool of secondary metabolites within the plant. Eventually, the presence of at least eleven classes of phytoconstituents viz. alkaloids, flavonoids, phenolics, glycosides, saponins, starch, phytosterols, coumarins, tanins, resins and quinones were demonstrated. Among the four partitonates, ethyl acetate soluble fraction of A. barbata illustrated the maximum types of secondary metabolites qualitatively. The ability of the crude methanol extract (MEAB) and its ethyl acetate soluble fraction (EAAB) to suppress nociception both centrally and peripherally were investigated in Swiss albino mice by tail immersion method and acetic acid-induced writhing method, respectively. At the 90th minute of the tail immersion study, both MEAB and EAAB administered at the doses of 250 and 500 mg/kg body weight (MEAB1, MEAB2, EAAB1, EAAB2) exhibited 240.41%, 285.34%, 302.83% and 339.60% elongation of pain response, respectively, in comparison to the standard, pentazocine which effectuated 421.36% elongation at the same mark. Moreover, the test samples at the same doses as before exhibited reduction of pain sensation by 66.81%, 74.08%, 76.81%, and 83.52%, respectively, in the acetic acid-induced writhing response in mice. Both the central and peripheral analgesic potentials of EAAB were discernibly higher than those of MEAB at both doses. The findings of the study represents the pharmacological potential of this species in appropriate animal model for the first time and provides valid foundation to warrant future scientific endeavors into the plant.

Abstract Background Begonia barbata Wall is an important medicinal plant in Bangladesh used to treat several human diseases. The intention of the existing work was to determine in vitro and in vivo pharmacological properties of petroleum-ether, dichloromethane, and ethyl acetate soluble fractions of methanol extract of B. barbata whole plant (MEBB). The total phenolic content (TPC) was determined by Folin-Ciocalteu test while antioxidant activity assay was performed by DPPH radical quenching process. Tail immersion and acetic acid-induced writhing methods were utilized to evaluate analgesic effect in albino mice. To evaluate the hypoglycemic potential, glucose tolerance test is used. Castor oil-induced diarrhea method is utilized to figure out the anti-diarrheal action in mice. Thiopental-sodium-induced sleeping time test was exploited for the appraisal of CNS antidepressant action. Results Antioxidant activities of the test materials followed the order: dichloromethane fraction (DCMF) > ethyl acetate fraction (EAF) > petroleum-ether fraction (PEF). The EAF yielded maximum amount of phenolic compounds (12.47 mg of GAE/g of sample). The DMF was most effective in terms of thrombolytic activity while the EAF protected the membrane integrity of erythrocyte by 63.47% inhibition of hemolysis induced by heat. Among all fractions, the PEF (400 mg/kg body weight) demonstrated highest analgesic activity in both tail immersion test (maximum elongations as 262.053%) and acetic acid-induced writhing method (66.02% writhing inhibition). During anti-diarrheal test, the plant samples significantly diminished the frequency of diarrheal episodes in mice. Similarly, the plant samples decreased the sleeping duration induced by thiopental sodium. Conclusion The above outcome exposed that B. barbata possesses significant pharmacological potential, which validates its use in Bangladesh folk medicinal practices.

Crude Methanol Extract

Boehmeria glomerulifera Miq. is an indigenous plant of Bangladesh. Traditional healers use this plant to treat various diseases. The crude methanol extract of whole plant of B. glomerulifera and its Kupchan fractions were screened for in vitro membrane stabilizing and only the crude extract at doses of 200- and 400- mg/kg body weight were screened for analgesic activity in mice model in order to establish the medicinal values of this plant. The membrane stabilizing activity of the extractives was evaluated by the ability of test materials to inhibit hypotonic solution- and heat-induced haemolysis of human erythrocytes. Moreover, the analgesic activity of methanol extract was evaluated by acetic acid induced writhing method and tail immersion method in mice. In hypotonic solution- and heat-induced conditions, the crude methanol extract showed inhibition of haemolysis by 64.80±0.34% and 21.63±0.76%, respectively as compared to 77.74±0.67% and 40.41±0.69% demonstrated by the standard, acetyl salicylic acid. On the other hand, the analgesic activity was determined for its peripheral and central pharmacological responses using acetic acid-induced writhing test and tail immersion method at doses of 200- and 400- mg/kg body weight. The extract reduced the acetic acid-induced writhings significantly (p < 0.05) in a dose dependent manner with the highest activity observed at 400 mg/kg (46.0%) body weight when compared to that of Diclofenac sodium (64.0%), as the standard drug. A significant increase (p < 0.01) of latency period was also found in tail immersion method. Therefore, the present study established that the methanol extract of B. glomerulifera possesses moderate membrane stabilizing and significant analgesic activities.Bangladesh Pharmaceutical Journal 19(2): 185-189, 2016

In the present study, we investigated the antinociceptive effects of the plant Vigna unguiculata spp dekindtiana using chemical and thermal tests in mice. The peripheral and the central analgesic activities of the methanol extract and its fractions were investigated in-vivo in albino mice using acetic acid induced-writhing test and hot plate models respectively. The result of the central analgesic effect showed that the methanol extract (VUME) at 400 mg/kg produced a significant (p<0.05) delay in reaction time in mice on hot plate compared to the control. Various fractions of the extract showed more potency compared to the crude extract. In acetic writhing model, the extract and the fractions demonstrated dose dependent reduction in writhing reaction induced by acetic acid in mice. The reduction was significant when compared to control which was suggestive of the analgesic effect of the plant. It was also seen that the extract and fractions showed an improved analgesic effect compared to diclofenac used as positive control in this model. Yohimbine (alpha adrenergic receptor antagonist) and cyproheptadine (serotonergic receptor antagonist) reversed the antinociceptic effect of the fractions in the hot plate model demonstrating the possibility of adrenergic and serotonergic involvement in eliciting the analgesic effect. Naloxone on the other hand, caused a reversal only in the butanol fraction meaning that this fraction may contain active principles that may mediate their analgesic effect through the opioid mechanism. In the writhing test, yohimbine abolished the analgesic effect of both hexane and butanol fractions. This may therefore, suggest that the analgesic effect of these fractions may be mediated through adrenergic pathway. In conclusion, the plant V. unguiculata subspecies dekindtiana possesses active principles with potential analgesic activity, establishing the folkloric use of the plant in managing pain.

Background: Polyalthia simiarum (Hook. F. &Thomson) exhibits different effects in human body. Objective: As a part of ongoing research on medicinal plants of Bangladesh, the present study is focused to investigate the analgesic and anti-inflammatory activities of stem bark of Polyalthia simiarum (Annonaceae). Methodology: The ethyl acetate (EA) and petroleum ether (PE) extracts were subjected to qualitative chemical investigation for the identification of different phytoconstituents. The analgesic activity was determined for its central and peripheral pharmacological actions using tail immersion method and acetic acid-induced writhing test. The anti-inflammatory activity was evaluated by carrageenan induced paw edema in rats. Analgesic and anti-inflammatory data were evaluated statistically analysed by Dunnett’s-T test. Result: Both extracts at the dose of 50- and 100 mg/kg b.w., produced significant increase in pain threshold in tail immersion method whereas significantly reduced the writhing caused by acetic acid in a dose dependent manner. The EA and PE extracts showed anti-inflammatory activities at 50- and 100 mg/kg body weight. Among all the extracts, the EA extract showed a dose dependent and comparable analgesic activity in all the tested methods and also reduced the paw edema considerably (27.5% and 39.1% inhibition after 4h), in dose dependent manner when compared to carrageenan induced control rat. Conclusion: Therefore, the EA and PE extracts of Polyalthia simiarum were capable to exhibit moderate analgesic and anti-inflammatory activities. This is the first report of analgesic and anti-inflammatory potential of Polyalthia simiarum and can be further investigated to isolate the active compounds responsible for the biological activities.
