Anti-inflammatory and anthelmintic activities of Solanum khasianum Clarke.

In order to scientifically appraise some of the folkloric uses of Solanum khasianum Clarke (Solanaceae), the present study was undertaken to examine the anti-inflammatory and anthelmintic properties of the berries of ethanol extract. Anti-inflammatory activity was tested in carrageenan induced rat hind paw edema method at three dose level of 200, 300, and 400 mg kg(-1) respectively, Diclofenac sodium (100 mg kg(-1)) was used as the reference standard. The anti-inflammatory activity of the extract was compared with standard and control. The anthelmintic activity of the extract was tested on tape worm, liver fluke, thread worm, and hook worm using two different concentrations, 100 and 200 mg mL(-1) respectively. Time taken for the inhibition of motility was noted and compared with the standard drug, Piperazine citrate 15 mg mL. The plant extract significantly (p < 0.01) reduced the inflammation of the rats when compared to the control group. Also, the ethanol extract of the plant paralyzed the worms followed by death, which was comparable with that of the standard. This study supports the folk claim.

Antidiabetic activity of flower buds of Michelia champaca Linn.

OBJECTIVE: To identify the antihyperglycemic activity of various extracts, petroleum ether (60-80°), chloroform, acetone, ethanol, aqueous and crude aqueous, of the flower buds of Michelia champaca, and to identify the antidiabetic activity of active antihyperglycemic extract. MATERIALS AND METHODS: Plant extracts were tested for antihyperglycemic activity in glucose overloaded hyperglycemic rats. The effective antihyperglycemic extract was tested for its hypoglycemic activity at two-dose levels, 200 and 400 mg/kg respectively. To confirm its utility in the higher model, the effective extract of M. champaca was subjected to antidiabetic study in alloxan induced diabetic model at two dose levels, 200 and 400 mg/kg respectively. The biochemical parameters, glucose, urea, creatinine, serum cholesterol, serum triglyceride, high density lipoprotein, low density lipoprotein, hemoglobin and glycosylated hemoglobin were also assessed in the experimental animals. RESULTS: The ethanolic extract of M. champaca exhibited significant antihyperglycemic activity but did not produce hypoglycemia in fasted normal rats. Apart from this extract, the crude aqueous and petroleum ether extracts were found active only at the end of the first hour. Treatment of diabetic rats with ethanolic extract of this plant restored the elevated biochemical parameters significantly (P<0.05) (P<0.01) and the activity was found dose dependent. CONCLUSION: This study supports the traditional claim and the ethanolic extract of this plant could be added in traditional preparations for the ailment of various diabetes-associated complications.
