The herbal preparation of the leaves of Solanum pubescens Pers (Solanaceae) is used in traditional medicine for the treatment of Epilepsy and febrile convulsions. A pilot study has confirmed the potency of the leaf of Solanum pubescens in the control of seizure in mice. The current study was aimed to identify the active phytochemical responsible for the activity. Results indicated that methanolic extract of Solanum pubescens at 300 mg/kg exhibited a significant P<0.05 delay in the latency of myoclonic spasms and tonic-clonic phase of seizure induced by PTZ, and also decreased the latency and increased the duration of phenobarbitone induced sleeping time. While the phytochemical studies showed the presence of alkaloids, resins, glycosides, carbohydrates, reducing sugar, fats and oils, flavonoids and terpenoids. The results suggested that the extract possessed anticonvulsant activity and central depressant effects which may be attributable to the...

An UV spectrophotometric method for the quantitative determination of Temozolomide (TMZ) in bulk and capsule was developed in present work. The parameters linearity, precision, accuracy, limit of detection and limit of quantitation were studied according to International Conference on Harmonization guidelines. UV spectroscopic determination was carried out at an absorption maximum of 328 nm using 0.1N Hydrochloric acid as solvent. In the UV spectroscopic method linearity over the concentration range of TMZ was found to be 2-18 µg/ml with a correlation coefficient 0.999. The limit of detection and limit of quantification were found to be 0.5271 and 1.6454 mg/ml respectively. Results of the analysis were validated statistically and by recovery studies. The proposed method is simple, rapid, precise, accurate and reliable and can be used for the routine quantitative analysis of TMZ in bulk and pharmaceutical...

Plants of medicinal importance though are quite well known among the Ayurvedic practitioners since years, yet many of them have not been standardized, validated and documented completely. Among such medicinally valuable plants, Salacia holds a place as an effective antidiabetic herb and many species of this plant are in use as anti-diabetics. The present study reports the phytochemical analysis of one of its species Salacia oblonga (SO) (roots and stems), belonging to the family Celastraceae (bittersweet), through various biochemical and chromatographic methods. TLC and HPTLC analysis of six different extracts of SO revealed numerous bands, indicating the presence of diverse groups of phytocompounds, many of them are assumed to contribute significantly to its antioxidant activity as well as, other biological activities. This type of analysis can help in fingerprint profiling of the plant and its various species. The identification and characterization of the phytocompounds can further help in finding out molecular targets/mechanism of action of the constituents of this herb that are responsible for its biological...

With the blend of Methocel K15, a synthetic polymer and xanthan gum, a natural polymer (3:1) was used in the formulation of matrix tablets to find out the effect of natural polymer in the sustained release dosage form. Direct compression process was applied for the preparation of Ketotifen fumarate tablets. The dissolution profiles were carried out by USP apparatus 2 (paddle) at 50 rpm in 500 ml 0.1 N HCl and distilled water. For interpreting the results a one way analysis of variance (ANOVA) was exploited. Statistically significant differences were found among the drug release profile from different matrices. At a higher polymeric content (60% of the total tablet weight), drug release from the combination of Methocel K15M and xanthan gum (3:1) was slower. On the contrary, at a lower polymeric level (30% of the total tablet weight); the rate of drug release was prominent. The best-fit release kinetics was accomplished with the Higuchi model followed by the zero-order plot, Korsmeyer and Hixson Crowell equations. One formulation showed drug...

The concerned study reveals the first time experimental investigation of Hypoglycemic and antihyperglycemic effect of seed extract of Acacia tortilis plant was in normoglycaemic and Alloxan-induced (135 mg/Kg body weight intraperitoneally) diabetic rats. The seed extract at the dose of 100 and 200 mg/kg body weight was administered orally once a day for 13 days and at the end of the experimentation Oral Glucose Tolerance Test (OGTT) and blood glucose estimation was done in all groups. The extract significantly lowered the blood glucose levels to an extent comparable to that produced by standard Oral hypoglycemic drug (Gliclazide 22 mg/Kg body weight) in both normal and diabetic rats. The results suggest that seed extract of Acacia tortilis possess significant antidiabetic activity. The extract seems promising for the development of a phytomedicine for diabetes mellitus in future...
