| Abstract | Lasianthera africana is a dark green leafy vegetable commonly consumed as food and used for treatment of several human ailments in Nigeria most especially south-east. This study investigated the phenolic composition and effects of methanol extract from L. africana leaves on enzymes linked to type-2 diabetes (α-amylase and α-glucosidase) and hypertension [angiotensin-1-converting enzymes (ACE)] as well as Fe$^{2+}$-induced lipid peroxidation in rat’s pancreas and kidney homogenates were evaluated. Phenolic contents and constituents were also determined using colorimetric methods and high performance liquid chromatography-diode array detector (HPLC-DAD) respectively. Our findings revealed that the extract inhibited α-amylase, α-glucosidase and ACE activities with IC$_{50}$ values of 0.192 and 0.21 mg/mL, and 57.06 μg/mL respectively. The extract also inhibited Fe$^{2+}$-induced lipid peroxidation in rats’ pancreas and kidney homogenates. Our findings revealed that the extract is rich in phenolic acids such as caffeic acid (59.97 mg/g), chlorogenic acid (58.23 mg/g) and ellagic acid (31.16 mg/g) as well as flavonoids such as quercetin (42.98 mg/g). These results give a clue to the potential use of L. africana leaves as an alternative agent for the control of glucose absorption and lowering of blood pressure in diabetic patients with hypertension. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
