Plants have provided mankind with herbal remedies for many diseases for many centuries and eventody. In India, herbal medicines have been the basis of treatment and cure for various diseases in traditional methods practiced such as Ayurveda, Unani and Sidha. Syzygium cumini Linn. (Myrtaceae) commonly known as jambul tree (English), having promising theraputic values with its various phytoconstituents. Preliminary Phytochemical investigation was carried out on the methanolic extract of Syzygium cumini Linn. Bark. It indices presence of Carbohydrates, Amino acids, Tannins, Saponins, phytosterols, Terpenoids, phenols and flavonoids. We are also quantitatively estimated total phenolic content, tannins and favaniods by using spectrophotometer. The total phenolic content was 580.23 ± 3.03 mg/g, tannin content was 534 ± 4.03 mg/ g while the flavonoid content was 315.42 ± 4.52 mg/g. The methanolic and aqueous extracts of bark were screened for antioxidant activity using Nitric oxide scavenging activity method, which showed significant persentage of inhibition in dose dependent manner. As antioxidant therapy is found to be useful in complicated disease status related with...

The present research work has been carried out for an optimized formulation of co-processed directly compressible vehicles in the preparation of the Acetaminophen mouth fast dissolving tablets (MFDTs). Acetaminophen was chosen due to its poor compression properties. Di-calcium Phosphate(DCP) was incorporated in the neutralized aqueous starch dispersion to prepare co-processed excipient. Co-processed direct compressible DCP and Starch used as co-processed excipient were taken in good formulation ratio such as (25:75) and Cross Povidone used as superdisintegrant. The effects of other superdisintegrants were studied in the best formulation F5. Formulation F5 was found to be optimum compressibility characteristics hardness 3.62±0.40 to 4.68±0.31 kg/cm2 with fast disintegration (10 sec) compare to other formulations...

The effect of aqueous seeds extract of Trigonella foenum graecumLinn was studied on Lactate dehydrogenase (LDH) activity of blood, liver and pancreas in normal and alloxan- induced diabetic mice. Our study showed that aqueous seeds extract, Oral administration of 50 mg/animal (0.5 ml of extract) in alternative days up to 7 days (1st, 3rd, 5th & 7th day). In alloxan induced diabetic mice, there was a significant increase in LDH activity of all the three tissues. The enzyme Lactate dehydrogenase showed significant decrease in the diabetic group treated with aqueous extract of tested plant when compared with the diabetic group. It is clear from the current data in this study that ginseng aqueous extract was the most efficient of the tested...

The objective of the project work was to study the effect of Hypoglycemic and Hypolipidemic activity of 2- hydroxychalcone on high fructose diet induced insulin resistance in male Wister Albino rats. Rats were rendered insulin resistant by feeding 66% (w/w) fructose and 1.1% (v/w) coconut oil mixed with normal pellet diet (NPD) for 3 weeks. Insulin resistance high fructose diabetic rats receiving hydroxychalcone intraperitoneally (i.p.) at the dose of 25mg/kg body weight daily for 7 consecutive days. At the end of the study blood glucose, serum insulin, glycosylated haemoglobin was estimated. The tissue was used for the assay of enzyme activity of Hexokinase, Glycogen, Glu-6-phosphatase and fru-1, 6 bis phosphatase were also estimated. Fructose diet with 2-hydroxychalcone significantly reduced the blood glucose, insulin, glu-6-phosphatase, fru-1, 6 bis phosphatase and significantly increase the hexokinase and glycogen activity. The flavonoid present in the cinnamon 2-hydroxychalcone were found to exhibit a significant Hypoglycemic activity in fructose fed insulin resistant...

Many cytological characteristics were studied in two species of Genus Delonix i.e., D. regia and D. elata . Delonix regia possessed 2n = 28 chromosome number. Both univalent as well as bivalents occurred invariably in this plant species, the former type being predominant over latter type. The chiasma frequency per PMc varied from 8-12 with average being 15.82. The chiasma frequency per chromosome averaged 0.56. The meiosis as well as meiotic indices was quite normal. Whereas Delonix elata is concerned for the above said chromosomal characteristics, it differed minutely in the frequency of chromosomal associations and chiasma frequency (per PMc and per chromosome). It does not show any change in comparison to D. regia in chromosome number, chromosomal distribution at AI and meiotic index. However rod bivalent occurred more frequently than ring type unlike D....
