Abstract
Bioactivity guided chemical investigation on active anti-diabetic constituents of the fruits of Cycas pectinata Griff. (FCP) characterized EAFr-5 as the most potent sub fraction which significantly reduced the blood glucose level to normal in STZ induced diabetic rats. It was shown to contain the biflavonoids amentoflavone (1) and 2,3-dihydroamentoflavone (2) which exhibited significantly high inhibitory potency against α-glucosidase (IC50 8.09 ± 0.023 and 9.77 ± 0.032 μM, respectively) and α-amylase (IC50 73.6 ± 0.48 and 39.69 ± 0.39 μM, respectively). This is the first report of bioactivity guided isolation of anti-diabetic constituents from the traditionally used fruits of Cycas pectinata Griff.

Abstract
To rationalize scientifically the traditional claim on use of Wedelia biflora (Linn.) D. C. for the treatment of wounds and infections, the present study was designed to evaluate the antimicrobial and wound healing activity of ethanol extract of leaves of W. biflora. In in vitro assays the test extract was subjected to antimicrobial activity by agar well-diffusion method and minimum inhibitory concentration method in different microbial strains. Wound healing activity of the test extract was studied by excision wound model and incision wound model in Wistar albino rats. In excision wound model, 97.90% wound healing was recorded in 10% w/w extract treated group on 16(th) days of postsurgery, whereas only 58.50% was observed in control group. In incision model, higher breaking strength, high hydroxyl proline content and histopathological study in extract treated groups revealed higher collagen redeposition than the control group. The agar well-diffusion evaluation and minimum inhibitory concentration established antimicrobial efficacy of ethanol extracts of W. biflora. These observations established the traditional claim and therapeutic activity of W. biflora and it could be a potent wound healing candidate for use in future.

Abstract
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.
