The aqueous and alcoholic leaf extracts of Annona squamosa, Azadirachta indica and Calotropis procera were tested against the cattle ticks. The fresh and leaf powder extracts were tested individually and also in combinations under in vitro conditions. The extracts of A. indica showed maximum mortality rate of ticks followed by A. squamosa and C. procera when tested individually. In combination, the hot water extracts of leaf powder showed 100% mortality whereas ethanol and methanol extracts showed 83% and 80% of mortality respectively. Based on the above experimental results, it is confirmed that the selected plant materials possess more acaricidal activity against cattle ticks. Extracts in combination are more effective than single drug used. Since the herbal drugs are cost effective and easy to process, it can be used as an alternative medicine to control cattle...

Zanthoxylum rhetsa DC. shoot is highly priced and one of the most preferred folk vegetable among the Indigenous people of Arunachal Pradesh, India. It is also used as folk medicinal purpose among the Adi tribe of the state. The methanol extract of shoot were evaluated for total phenolic content (Folin-Ciocalteu’s method), total flavonoid content (colorimetric method) and antioxidant potential ((DPPH & ABTS). Folk use, various mode of cooking, demand as vegetable in the local market is also discussed in this paper. The methanol extract contains considerable phenolic (117.95±3.22 mg GAE/g) and flavonoid (120.14±2.31 µMRE/g) with no much significant correlation between the total content of phenolic and flavonoid and antioxidant potential was found as IC50 value of 271±3.5µg/ml were recorded in ABTS assay and IC50 value of 306± 4.21µg/ml was found in DPPH...

Phytochemical, HPTLC and Heavy metal analysis of Leaf of Leonotis nepetaefolia was done. Qualitative phytochemical screening of Leaf was done using different solvents which showed the presence of various vital secondary metabolites. Neutraceutical studies revealed the presence of carbohydrates, proteins and aminoacids. HPTLC studies confirmed the presence of flavonoids, diterpene, phenolic class of compounds. Heavy metal analysis showed the presence of Lead, Cadmium, Chromium and copper in all the samples...

The present study is carried out with the methanolic extract of leaves of Millettia pachycarpa benth. Traditional use of it inspired us to investigate the blood corpuscular protective power of this plant as it used as blood tonic in Chinese traditional medicine. By the phytochemical screening we have both flavonoids and steroids. There’s also alkaloids are found which have extensive physiologic action embodying analgesic activity. This investigation is made following the most simple, reliable and less time consuming method. As the human red blood corpuscular membrane is similar to lysosomal membranes that influence inflammatory process. Result obtained using methanolic extract of M. pachycarpa have better acceptance as it shows good response in inhibiting hemolysis (34.30%) at highest concentration and these investigation surely stimulate further screening and isolation...

An attempt was made to formulate and evaluate the 18-β-glycyrrhetic acid (GA) transdermal drug delivery system. Preformulation studies on the drug 18-β-glycyrrhetic acid were done which included description, solubility and compatibility studies. Solvent casting technique was used to prepare the transdermal patches. Four formulations were made with 400mg of 18-β-glycyrrhetic acid and by using polymers Hydoxypropyl methylcellulose (HPMC) and Ethyl cellulose (EC) with different concentration of menthol (2%, 5%) as penetration enhancer. Interaction of drug and polymer was confirmed by FTIR studies. Transdermal patches were evaluated for the weight, thickness, percentage moisture uptake, folding endurance, water vapor transmission rate, in-vitro release and in-vivo release studies. This was done for four formulations F1, F2, F3, and F4. The F1 formulation showed a good release profile due to increase in concentration of penetration enhancer. The accelerated short term stability study indicated that the optimized formulation F1 has very good stability at 4 o / 40 o / 60 o for a period of 3...
