Preliminary assessment of free radical scavenging, thrombolytic and membrane stabilizing capabilities of organic fractions of Callistemon citrinus (Curtis.) skeels leaves
BACKGROUND Callistemon citrinus (Curtis.) (Family- Myrtaceae) is a popular evergreen shrub in Bangladesh. In the present study, the leaves of this plant have been assessed comprehensively for free radical scavenging, thrombolytic and membrane stabilizing activities. METHODS The leaves were collected, powdered and extracted with methanol. The extract was then concentrated and successively frac...
متن کاملPhysico –chemical Characteristics of Tincture from Asparagus Racemosus Willd
Various strength of alcohol were utilized for the preparation of tincture of asparagus racemosus roots by maceration for 7, 14 and 21 days. 50% (V/V) alcohol after 21 days of maceration showed maximum yield of total solid. The tinctures were evaluated by studying their different physico-chemical characteristics along with thin-Layer chromatography.
متن کاملBiological activities of Asparagus racemosus.
Cytotoxic, antioxidant, tyrosinase inhibitory, antimicrobial activities of the crude ethanol extract of dry powdered roots of Asparagus racemosus (Liliaceae) were investigated. The LC(50) to brine shrimp was 2189.49 microg/ml; the EC(50) for DPPH radical scavenging was 381.91 microg/ml; the IC(50) for tyrosinase inhibition was 7.98 mg/ml. The extract was active at 5-20 mg/ml against various pat...
متن کاملSteroidal saponins from the roots of Asparagus adscendens Roxb and Asparagus racemosus Willd
Phytochemical constituents of Asparagus adscendens and Asparagus racemosus are being reported in the present communication. Two new sarsasapogenin glycosides have been isolated, one from each of the species. Structure elucidation of 1 and 10 has been accomplished through the extensive use of 1Dand 2D-NMR experiments including H-H (DQFCOSY), H-C (HMQC, HMBC) spectroscopy along with mass spectros...
متن کاملAntioxidant and hepatoprotective action of Asparagus racemosus Willd. root extracts.
The antioxidant activities of the crude hydro-alcoholic extract (CE) and its four fractions viz. methanol (MF), ethyl acetate (EF), n-Butanol (BF), and precipitated aqueous (PAF) of A.racemosus roots tested decreased in the order of EF > MF > CE > BF > PAF when investigated by DPPH free radical scavenging assay. Under iron induced lipid peroxidation almost similar results were observed except t...
