Abstract:

Consumers rely on medical plants for their health benefits. Jackfruit leaves and Indian jujube leaves are commonly used in traditional remedies to address conditions such as ulcers and gout. This study was carried out to determine the phytochemical composition of Artocarpus heterophyllus and Ziziphus mauritiana leaves by conducting alkaloid and coumarin tests, pigments analysis, and phenolic compound profiling. Antioxidant activity was assessed using DPPH radical scavenging assay on extracts prepared with 50% and 100% ethanol as solvents. The colour (L* value) of each leaf showed significant v

Abstract:

Background: SARS COVID - 19, an infectious disease that is declared as pandemic by WHO and emerging again with newer strains. Heart failure is another deadly disease condition to which geriatric population is more susceptible. Few phytochemicals present in tamarind leaves like apigenin and epicatechin were reported to inhibit the SARS - COV - 2 enzyme named PDB ID : 6 LU7. Ethanolic extract of tamarind leaves was also proposed to reduce the prolongation of QT and RR intervals of ECG in Wistar rats along with lowering the serum enzymes' levels like LDH and CPK indicating cardiac protection in d
