Formulation, Optimization and Evaluation of Moringa Oleifera Leaf Extract Loaded Microemulsion for Enhanced Anti-Diabetic Efficacy

Abstract

Moringa oleifera (M. oleifera), the “miracle tree”, thrives globally in almost all tropical and subtropical regions, but it is believed to be native to Afghanistan, Bangladesh, India, and Pakistan. The Moringa family comprises 13 species (M. oleifera, M. arborea, M. rivae, M. ruspoliana, M. drouhardii, M. hildebrandtii, M. concanensis, M. borziana, M. longituba, M. pygmaea, M. ovalifolia, M. peregrina, M. stenopetala), of which M. oleifera has become well known for its use in nutrition, biogas production, fertilizer, etc. Moringa has the unique property of tolerating drought. Studies have shown that M. oleifera is among the cheapest and most reliable alternatives for good nutrition. Nearly all parts of the tree are used for their essential nutrients. M. oleifera leaves have a high content of beta-carotene, minerals, calcium, and potassium. Dried leaves have an oleic acid content of about 70%, which makes them suitable for making moisturizers. The powdered leaves are used to make many beverages, of which “Zija” is the most popular in India. The bark of the tree is considered very useful in the treatment of different disorders such as ulcers, toothache, and hypertension. Roots, however, are found to have a role in the treatment of toothache, helminthiasis, and paralysis. The flowers are used to treat ulcers, enlarged spleen, and to produce aphrodisiac substances. The tree is believed to have incredible properties in treating malnutrition in infants and lactating mothers .The present review aims to sum up the updated insight regarding the pharmacological activities, worldwide research analysis, toxicological, phytochemical, and ethno medicinal properties of M. oleifera.
