The petroleum (Pet.E), methanol (MeOH) and chloroform (CHCl3) extracts of Rauvolfia canescens (whole plant), Desmodium heterocarpon (whole plant) and Vitex negundo (leaf CHCl3 MeOH and root Pet. E.) have been thoroughly screened through residual film assay against T. castaneum adults and the repellent activity tests were also carried out on the same to find biological activities. The residual film assay offered promising results with remarkable activity against the adult beetles of T. castaneum. A perusal of the data achieved in this experiment clearly showed the presence of insecticidal properties in Rauvolfia canescens (whole plant), Desmodium heterocarpon (whole plant) and Vitex negundo extracts as well as traces of repellent potential. For repellency D. heterocarpon (whole plant /Pet. Ether) extract and V. negundo (leaf /Pet. Ether) extract were weakly active (P <0.05) and R. canescens (whole plant /Pet. Ether) extract and V. negundo (root /Pet. Ether) extract were mildly active (P<0.01); while the rest showed no repellent activity against the adults beetles of T. castaneum. Comprehensive phyto-chemical analyses of the test...

The World Health Organization survey indicated that about 70-80% of the world’s populations rely on non-conventional medicine, mainly of herbal sources, in their primary healthcare. Among them parasitic plants are well known, 20 different species are belonging to the genus Dendrophthoe falcate (Loranthaceae) found all over the world, seven of which are found in India. The hemiparasite, Dendrophthoe falcata (L.f.) is one of the seven species present in India. It is used in the treatment of ulcer, asthma, pulmonary TB, wound healing, menstrual disorder, also used as an aphrodisiac. The water extract of Dendropthoe falcata showed satisfactory antimicrobial activity against gram-positive strains Staphylococcus aureus, Bacillus subtilis and gram-negative strains Escherichia coli; while methanolic extract of Dendropthoe falcata shows satisfactory antioxidant...

Spirulina platensis is a blue-green alga that widely used as a food supplement over worldwide. Two models were used to study the effects of Spirulina platensis on nociception which was induced by acetic acid (Writhing test), formalin (Paw licking test). Spirulina platensis was administered in the dose range of 200 and 400 mg/kg orally 1 h before pain induction. Spirulina platensis contains β-carotene and biliproteins (phycocyanin and biliphycocyanin). Oral administration of Spirulina platensis revealed dose-dependent antinociceptive effect in all the models for antinociception, and it blocked both the neurogenic and inflammatory pain, and the nociceptive activity was comparable with the reference drug. The results indicate that 400 mg/kg dose of Spirulina platensis showed significant antinociceptive activity. The activity can be related with the significant biliprotein such as phycocyanin and biliphycocyanin that have potent antioxidant...

In the present study we screened four medicinal plants for the α-amylase inhibitory activity of each extracts phytochemicals, and it was determined based on the colorimetric assay using acarbose as a reference compound. The aqueous and ethanol extracts of the medicinal plants viz. Enicostemma littorale, Achyranthes aspera, Abutilon indicium, and Tridax procumbens were shown moderate α-amylase inhibitory activity against a reference, an account of that Achyranthes aspera shows potent activity towards remaining. Not only leaves but also the whole plant is used for comparative in-vitro study of inhibition of α- amylase...

The quality control assessment of herbal formulations is of great significance to justify their acceptability in the modern system of medicine though the drug may be therapeutically potent. Ayurvedic formulations prepared by several manufacturers are guaranteed to carry out the quality control test as per the standards mentioned in the Ayurvedic Formulary of India. Though the standards have been followed, still the variability in their results has been observed when compared between the same formulations. Vyoshadivati is one such polyherbal formulation consisted of 13 drugs and treated for ailments viz. Pinasa (coryza), Pratishaya (Rhinitis), Swarabheda (Hoarseness of voice), etc. An attempt is made here to compare Vyoshadivati prepared by GMP certified pharmacies with In house preparation. Results revealed that all the samples differ in their organoleptic, pH, and physicochemical properties. Thin Layer Chromato-graphic study showed sample B, D and E have an almost similar number of bands at the wavelength of 255 nm and 365 nm. Major difference was seen in disintegration time and hardness of sample A, i.e....
