Re-extraction * It is a small shrub which grows up to 3 feet. * Oblong shaped pods or fruit cases. * Flowers are yellowish in color and asymmetric. * Leaves are obovate, smooth, opposite and rounded in shape. Collection of plant leaves and make the powder form Revealed the presence of four chemical constituents: Crude organic extract from Cassia italica leaves Dr. Mohammed Sohail Akhtar Assistant Dean (Research). 1- Four structures of Cassia italica leaves have been identified under the microscope: Paracytic stomata. Bent trichomes. Pitted vessel. Groups of fibers with calcium oxalate. 2- Preliminary phytochemical screening indicated the presence of: Alkaloids. Anthraquinone glycosides. Flavonoids. Phenols. School of Pharmacy College of Pharmacy and Nursing Graduation project B-pharm 2014-2015 PHCY382 Pharmacognostic evaluation and cytotoxic activity of Cassia italica leaves grown in Oman. So, Middle polar and polar extracts are more active against the brine shrimp larvae. Flavonoids - Amount of crude extracts obtained from Cassia italica leaves after 72 hours of the maceration in ethanol was 7.45 g. - The amount of fractionated extracts is listed in the table below. Different qualitative tests have been done to detect the presence of different plant secondary metabolites in Ethanolic extract of Cassia italica leaves. 125mcg/ml MORPHOLOGY Preliminary phytochemical screening Thank you Brine Shrimp Test Microscopy of leaves powder 1- Alkaloids. 2- Anthraquinone glycosides. 3- Flavonoids. 4- Phenols. 5- Saponins. 6- Tannins. 10mg/ml - Cassia italica is a wild distributed plant in tropical regions of the world, deserts and semi deserts. - In Oman, it could be found in many regions (Dhofar, Muscat, Al-Sharqiya and Al-Dakhliya) - Locally known as (Holoul) Dr. Shyam Sundar Acting Associate Dean & Assistant Dean. - Crude extract was re-dissolved in (ethanol:distilled water 1:1 mixture). - Re-extracted with Petroleum ether (50ml x 2) and chloroform (50ml x 2) By Separating funnel. - Solvents were removed using rotary evaporator. - Petroleum ether, Chloroform and Hydro-Alcoholic extracts. 1.
