Phytochemical Screening and Antinociceptive and Antidiarrheal Activities of Hydromethanol and Petroleum Benzene Extract of Barks.

. is traditionally used for treating diarrhea, wounds, cold, fever, hepatitis, dyspepsia, and heat stroke. . To investigate the qualitative phytochemical constituents of hydromethanol (HMPB) and petroleum benzene extract of barks (PBMPB) and to evaluate their antinociceptive and antidiarrheal activities. . Phytochemical constituents and antinociceptive and antidiarrheal activities were determined and evaluated by different tests such as Molisch's, Fehling's, Mayer's, Wagner's, Dragendorff's, frothing, FeCl, alkali, Pew's, and Salkowski's test, general test of glycosides, Baljet and NHOH test, formalin-induced paw licking, acetic acid-induced writhing, tail immersion, and hot plate tests, and castor oil and MgSO induced diarrheal tests. . These extracts revealed the presence of saponins, flavonoids, and triterpenoids and significantly ( < 0.05, versus control) reduced paw licking and abdominal writhing of mice. At 30 min after their administration, PBMPB revealed significant increase in latency ( < 0.05, versus control) in tail immersion test. In hot plate test, HMPB and PBMPB 200 mg/kg showed significant increase in response latency ( < 0.05, versus control) at 30 min after their administration. Moreover, both extracts significantly ( < 0.05, versus control) inhibited percentage of diarrhea in antidiarrheal models. Study results indicate that . may provide a source of plant compounds with antinociceptive and antidiarrheal activities.
