Background: Lagerstroemia speciosa (L.) Pers is one of the most valuable plants due to its ornamental and pharmacological relevance. It is known for its anti-diabetic activity with proved potent blood sugar-lowering activity. The anti-diabetic activity is due to presence of its biologically active component corosolic acid. Moreover, L. speciosa and its novel purified compounds are also well-known for its several biological activities with beneficial health benefit on the human being. Objectives: This review provides a summary of pharmacokinetics, toxicity, and pharmacological properties of L. speciosa and its purified phytochemicals which may help researchers for building up new researches in near future. Methods: The current article is prepared by collecting through various online and offline databases. Preliminary source of study and data collection for outlining the review was research articles and reviews that have been already published by many reputed publishers, including Springer, Elsevier, Taylor & Francis imprints, BMC, Willy, The Norwegian Academy of Science and Letters, Environmental health prospective (EHP), and PLOS One. Result: The available studies results suggested that the L. speciosa and its phytochemicals showed antidiabetic, anticancer, anti-inflammatory, antimicrobial, antioxidant, antiviral, anti-obesity, and cardio-protective activities. Pharmacokinetic stud-ies suggested the low bioavailability of its purified compounds. However, nano-encapsulation can improve the bioavaila-bility related issue and effectively potentiate the medicinal properties of its constituents. Conclusion: Considering the worthy pharmacological properties, L. speciosa is considered as a potent source of several novel drugs. Though, still preclinical and clinical studies are needed to reveal the targets, molecular mechanisms, bioavail-ability, and toxicity of its constituents.

Lagerstroemia speciosa (L.) Pers (Hindi - Jarul, Taglog - Banaba) a member of Lythraceae family is found all over India, specially in Bengal, Assam and Deccan Peninsula. The leaves of L. speciosa is widely used for lowering blood sugar levels in Philippines, Japan and Taiwan. Pharmacognostical investigation of leaves of L. speciosa was done by evaluating its morphological, microscopical studies, Physicochemical and phytochemical parameters. Rasa Nirdharana was done. Microscopical study revealed presence of epidermal cells contained clusters of rosette aggregate calcium oxalate crystals and few cells were mucilaginous. Lower epidermis showed the presence of anomocytic stomata. Physical constants of leaf powder showed, loss on drying - 3.8%, total ash - 6.7%, acid insoluble ash - 1.039%, water soluble extractive value - 8.88%, alcohol soluble extractive value - 4.49% and pH - 5.75. Preliminary phytochemical study revealed the presence of alkaloids, flavonoids, saponins, triterpenes, tannins, proteins and iron. Rasa Nirdharana confirmed the leaves are Kashaya in Rasa. The Pharmacognostical study was useful for authentication of leaves of Lagerstoemia speciosa.

Phytochemical Studies

The aim of this study was to know the hypoglycaemic and hypolipidaemic activities of water extract of bungur (Lagerstroemia speciosa [L.] Pers.) leaves in alloxan-induced diabetic rat. Phytochemical studies was conducted to determinate the tannin-contents of the water extract (WE). Male Wistar rats (150- 180 9 BW) were used in this study. The rats were divided into six groups: nonnal control; diabetic control; glibenclamide; WE 0.1 g/200 9 BW; WE 0.2 g/200 9 BW; and WE 0.5 g/200 9 BW. Dried leaves of bungur extracted with boiling water (50 g/L) for 30 minutes. The extract administered orally. Fasting blood glucose, triglyceride, and total cholesterol were determined at 0, 2, 4, 6 hours after treatment. Total phenol, ellagitannin, gallotannin, and condensed-tannin were determined from the WE. The results showed that WE exhibited hypoglycaemic activity at doses 0.2 g/200 9 BW and 0.5 g/200 9 BW. The last dose showed similar hypoglycaemic activity compared with glibenclamide. All doses showed the hypolipidaemic activity higher than glibenclamide. Phytochemical studies showed that the WE containing total phenol 0.025%; ellagitannin 0.011%; gallotannin 0.0199%; and condensed-tannin 0.0167%.

Abstract L. speciosa is a medium-size to large deciduous tree distributed throughout India, Myanmar, Sri Lanka and Bangladesh, except for dry areas. The rate of growth is moderate and the trees grow best on deep, rich, well-drained alluvial loam, with sufficient moisture. The timber is used for buildings, ships, boats, dug-out canoes, bridges, water tanks, railway wagons, bus bodies, turnery, cooperage and many other purposes. L. speciosa is suitable for afforestation of sites prone to dampness and waterlogging, and can be grown successfully from seed, seedlings and stump plants. It is used in farming systems, as it is particularly suited to paddy rice agroforestry. L. speciosa is one of the most beautiful ornamental trees when in flower and is widely planted in India in gardens, parks, homesteads and avenues.
