Soxhlet apparatus

Leaves of Xylosma longifolium, Hyptis suaveolens and Oreocnide integrifolia collected from the Imphal East District, Manipur were analysed for phytochemical constituents. Leave extracts were prepared with methanol by Soxhlet apparatus. Alkaloid, phenol, flavonoid, tannin, terpenoid, steroid, saponin and glycosides were detected in the three samples. Glycosides was absent in Xylosma longifolium and terpinoid in Oreocnide integrifolia. Steroid and saponin were also not found in Hyptis suaveolens. Total phenol, flavonoid and tannin contents were determined by Folin-Ciocalteu, Aluminium chloride and Folin-Denis method respectively. The total phenol contents in terms of gallic acid equivalent were 57.38±2.563 mg/g, 65.00±0.475 mg/g and 50.87±0.035  mg/g of dry wt;  total flavonoid contents in terms of quercetin equivalent were 36.70±0.676  mg/g,  49.24±0.521 mg/g and  32.78±1.753mg/g of dry wt.  and total tannin contents in terms of tannic acid equivalent  were  31.08±1.300 mg/g, 41.14±0.850 mg/g and 30.95±0.759 mg/g of dry wt. in the methanolicS leave extract of X.longifolium,  O.integrifolia and H.suaveolens  respectively .The order of total phenol , flavonoid and tennin contents of the samples were Oriocnide integrefolia> Xylosma longifolium >Hyptis suaveolens. It shows that Oriocnide integrefolia has the highest medicinal value than the two studied plants.  The present study evidence that these plants are of therapeutic potential as a good number of bioactive chemical compounds have been confirmed.

  Clerodendron serratum spreng is very much effective in preventing Dalton’s Ascetic Lymphoma cell in mice which was confirmed by evaluating the hematological parameters. Peritoneal cell count, solid tumors volume, body weight and histopathological studies. This holds great promise for future research in human beings. The anticancer properties of Clerodendron serratum spreng will provide useful information in the possible application in cancer prevention and cancer therapy. The treatment with ethanolic and aqueous extracts of Clerodendron serratum spreng significantly altered all the parameters, near to normal. Maximum alteration of parameters occurred in the group treated with the aqueous extract at the dose of 300 mg/kg/day.
