Botanical Description

Mimusops elengi is a small to medium-sized evergreen tree, typically reaching heights of 9 to 15 metres, though mature specimens in favourable conditions may attain 20 metres. The tree possesses a dense, rounded crown and a straight, cylindrical bole with rough, dark greyish-brown bark that is deeply fissured and cracked. It is a slow-growing, long-lived species, often planted as an ornamental and shade tree in gardens, temples, and along avenues.

Key Identification Features:

The leaves are simple, alternate, and spirally arranged, measuring 5 to 14 centimetres in length and 2.5 to 6 centimetres in width. They are elliptic to oblong-lanceolate, glossy dark green above and paler beneath, with a distinctly wavy or undulate margin and an acuminate apex. The petiole is 1 to 2.5 centimetres long, often with small stipules at the base. New leaves emerge coppery-red before maturing to deep green.

The flowers are small, solitary or in axillary clusters, creamy-white to pale yellow, and highly fragrant, especially at night. Each flower is about 1.5 centimetres across, with 8 petals arranged in two whorls and 8 sepals in two whorls. The fragrance of Bakul flowers is legendary in Indian poetry and culture, associated with romance, devotion, and the monsoon season.

The fruit is a berry, ovoid to ellipsoid, 2 to 3 centimetres long, initially green and turning yellow-orange to red when mature. Each fruit contains a single, large, ovoid seed surrounded by a thin layer of edible but astringent pulp. The seed has a hard, brown, shiny testa and a distinctive scar on one side.

Distribution: Mimusops elengi is native to the Indian subcontinent, including India, Sri Lanka, Bangladesh, Myanmar, and the Andaman and Nicobar Islands. It is widely cultivated throughout tropical Asia, including Thailand, Malaysia, Indonesia, and Vietnam, as well as in parts of Africa and Australia, both as an ornamental and for its medicinal value. It grows from sea level to an altitude of 1,500 metres.

Conservation Status: The species is not listed as threatened. It is widely cultivated and naturalised across its native range, with stable wild populations.

Etymology

The generic name Mimusops is derived from the Greek "mimos" meaning "mimic" or "imitator," and "ops" meaning "face" or "appearance," likely referring to the superficial resemblance of the flowers to those of other genera. The specific epithet elengi is derived from the Sanskrit name "Bakula" or its vernacular derivatives, which have been used for millennia. The name Bakul itself is of ancient Indian origin, appearing in Vedic and classical Sanskrit literature.

6. Mechanisms of Action

6.1 Anti-inflammatory Activity: Cytokine Suppression and COX Inhibition

The anti-inflammatory activity of Mimusops elengi is mediated through multiple pathways. Triterpenoids such as lupeol, betulinic acid, and taraxerol inhibit the production of pro-inflammatory cytokines including TNF-α, IL-1β, and IL-6. These compounds also suppress the expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS), reducing the production of prostaglandins and nitric oxide. The saponins in the bark extract have been shown to stabilise lysosomal membranes, preventing the release of pro-inflammatory enzymes and reducing tissue damage in animal models of acute inflammation.

6.2 Antimicrobial Activity: Membrane Disruption and Enzyme Inhibition

The antimicrobial action of the plant is attributed to its triterpenoid saponins and phenolic compounds. Saponins disrupt the lipid bilayer of microbial cell membranes, causing leakage of intracellular contents and cell death. Phenolic compounds such as gallic acid and quercetin inhibit essential bacterial enzymes, including DNA gyrase and dihydrofolate reductase, and generate oxidative stress within the microbial cell. The combination of these mechanisms results in broad-spectrum antibacterial and antifungal activity, as confirmed by in vitro studies against multiple pathogenic strains.

6.3 Cardioprotective Activity: Antioxidant and Anti-apoptotic Effects

The cardioprotective effect of the bark extract has been demonstrated in isoproterenol-induced myocardial infarction models. The mechanism involves reduction of oxidative stress through upregulation of endogenous antioxidant enzymes such as superoxide dismutase (SOD), catalase, and glutathione peroxidase. The extract also inhibits lipid peroxidation and reduces the leakage of cardiac marker enzymes. Furthermore, the extract modulates apoptotic pathways, decreasing the expression of pro-apoptotic proteins (Bax) and increasing the expression of anti-apoptotic proteins (Bcl-2), thereby preserving myocardial tissue integrity and function.

6.4 Antidiabetic Activity: Enzyme Inhibition and Glucose Uptake

The hypoglycaemic activity of Mimusops elengi is mediated through several mechanisms. The leaf and bark extracts inhibit α-amylase and α-glucosidase, key enzymes in carbohydrate digestion, thereby reducing postprandial glucose absorption. The extracts also enhance glucose uptake by peripheral tissues, possibly through increased insulin sensitivity. In animal models of streptozotocin-induced diabetes, treatment with the extract significantly reduced blood glucose levels, improved insulin levels, and normalised lipid profiles, suggesting both pancreatic and extra-pancreatic mechanisms of action.

6.5 Hepatoprotective Activity: Antioxidant and Anti-inflammatory Synergy

The hepatoprotective action of the bark and leaf extracts is primarily attributed to their antioxidant and anti-inflammatory properties. In animal models of carbon tetrachloride (CCl4) and paracetamol-induced hepatotoxicity, pretreatment with the extract significantly reduced levels of serum transaminases (ALT, AST), alkaline phosphatase, and bilirubin. The mechanism involves scavenging of free radicals, restoration of hepatic glutathione levels, and inhibition of lipid peroxidation in the liver. The anti-inflammatory compounds in the extract further reduce cytokine-mediated hepatic damage, resulting in overall preservation of liver architecture and function.

6.6 Wound Healing Activity: Collagen Synthesis and Angiogenesis

The wound healing property of the plant is attributed to its ability to promote collagen synthesis, epithelialisation, and angiogenesis. The bark and leaf extracts stimulate fibroblast proliferation and increase the deposition of hydroxyproline, a marker of collagen production. The extracts also promote the formation of new blood vessels, improving blood supply to the wound site and accelerating tissue regeneration. The antimicrobial properties of the extract prevent wound infection, further facilitating the healing process. In animal models, wounds treated with Mimusops elengi extracts showed faster contraction, reduced scar formation, and improved tensile strength compared to controls.
