Comparative Review on Phytochemical and Pharmacological Potential of Butea Monosperma

India is regarded as one of the world’s twelve mega-diversity regions, with an extraordinary variety of therapeutic plants that have been used in traditional healthcare practices for centuries (Khare, 2007; Singh & Singh, 2010). One of the most ethnobotanically, culturally, and medicinally significant plants is Butea monosperma (Lam.) Taub. (Palash, Dhak, Flame of the Forest). This medium-sized tree with an open crown belongs to the family Fabaceae and is widely distributed across India and neighboring regions (Kirtikar & Basu, 1999). Ancient Ayurvedic texts describe four varieties of Palash—Rakta, Pita, Shveta, and Nila—of which the Rakta variety is the most common and widely used in ethnopharmacology (Sharma, 2006).The Palash tree is mentioned in Vedic literature, particularly in the Brahmana texts, where it is regarded as a sacred plant used in Yajna (fire rituals) (Dash, 2001). The flowers, wood, and leaves of the tree are closely associated with various traditional and cultural practices in India. Ayurvedic practitioners also associate scientific relevance with several traditional uses of Palash, including the use of its natural floral pigments, which are considered safe, non-allergic, and skin-friendly, especially during the festival of Holi (Patel et al., 2015).

Numerous phytochemical investigations have been conducted on Butea monosperma, revealing the presence of several bioactive constituents such as glycosides, flavonoids, and saponins, which contribute to its medicinal properties.

In addition to its medicinal value, Butea monosperma also plays an important role in economic and ecological contexts. Its flowers are used as a natural colouring agent, particularly during festivals like Holi, and its leaves are commonly used to make biodegradable plates. The plant also supports lac production and serves as a source of fibre and fodder. Overall, Butea monosperma is a versatile plant with considerable therapeutic and commercial importance. However, further scientific validation through detailed experimental and clinical studies is necessary to fully establish its efficacy and safety in modern medicine (Burlia et al., 2007; Khare, 2007).

3.PHARMACOLOGICAL ACTIVITIES ON BUTEA MONOSPERMA

3.1 Antioxidant and Free Radical Scavenging Activity

Butea monosperma possesses considerable antioxidant potential. Extracts obtained from the stem bark, especially those prepared using acetone and methanol, demonstrate strong free radical scavenging ability, mainly due to their high phenolic content. The flowers, which contain bioactive compounds such as butein, also exhibit antioxidant and apoptosis-inducing properties. These findings suggest its possible role in managing oxidative stress–associated disorders. (Sehrawat & Kumar, 2012).

3.2 Antioxidant and Anticonvulsant Activities

Butea monosperma leaves are a rich source of flavonoids that demonstrate considerable antioxidant and anticonvulsant potential. Laboratory studies have shown that these extracts effectively neutralize free radicals and possess strong reducing capacity. In animal experiments, the flavonoid fraction has been found to decrease seizure severity and frequency, while also delaying the onset of seizures in chemically and electrically induced models. The protective effects increase with dosage and are likely linked to the extract’s antioxidant and neuroprotective properties. These observations highlight its possible value in managing epilepsy and other neurological conditions associated with oxidative stress. (Bala et.al., 2023)

3.3 Antimicrobial Activity

Butea monosperma leaves possess strong antimicrobial properties against various Gram-positive and Gram-negative bacteria as well as fungi. Extracts prepared with ethanol and methanol exhibit broad-spectrum, dose-dependent inhibition. This activity is largely due to bioactive compounds such as dodecane, phytol, squalene, and lup-20(29)-en-3-one. Aqueous and alcoholic extracts have also been shown to suppress the growth of multiple bacterial and fungal strains. The presence of diverse phytochemicals contributes to this antimicrobial effect. These results validate the traditional use of the leaves in combating infections. Overall, Butea monosperma leaves show significant promise as a natural antimicrobial agent (Goyal et al., 2019)

3.4 Hepatoprotective Activity

Butea monosperma bark demonstrates significant hepatoprotective effects in experimental models of liver injury induced by thioacetamide. The ethyl acetate fraction of the bark exhibits strong antioxidant activity, including superoxide radical scavenging and inhibition of lipid peroxidation. Pretreatment with the extract effectively normalized altered serum biochemical markers such as SGOT, SGPT, ALP, bilirubin, and albumin. Additionally, it restored the levels of key hepatic antioxidant enzymes, including SOD, CAT, GSH, and GR. Histopathological analyses confirmed protection of liver tissue and preservation of normal architecture. These results suggest that the hepatoprotective activity of Butea monosperma bark is primarily due to its antioxidant properties and support its traditional use in managing liver disorders. (Kaur et.al.,2017)

3.5 Antidiabetic Activity

Butea monosperma has shown notable antidiabetic potential in experimental studies. Its extracts, which are rich in flavonoids, polyphenols, and other bioactive compounds, have been reported to lower blood glucose levels, enhance insulin sensitivity, and improve antioxidant status in diabetic animal models. Additionally, the plant helps protect pancreatic β-cells and other tissues from oxidative stress–related damage, contributing to its overall antidiabetic effects. These findings indicate that Butea monosperma may serve as a valuable herbal adjunct for the prevention and management of diabetes. (Parween et al., 2021)

3.6  Antidepressant Activity

Butea monosperma has shown promising antidepressant potential in preclinical studies. Methanolic and ethanolic extracts of the plant demonstrate central nervous system–modulating effects, including mood enhancement and stress alleviation, in animal models of depression. These effects are likely attributed to the presence of flavonoids and chalcones, which may influence neurotransmitter activity. Overall, the findings indicate that Butea monosperma could be a valuable herbal option for the management of depressive disorders (Boya et al., 2025).

3.7Anti-Inflammatory exertion

 Butea monosperma flower excerpts, particularly the methanolic bit( MEBM), parade significant-inflammatory goods in experimental models. In albino rats, oral administration of MEBM at boluses of 600 and 800 mg/ kg produced cure-dependent inhibition of carrageenan- convinced paw edema and significantly reduced granuloma conformation in the cotton bullet model. The excerpt also dropped situations of serum lysosomal enzymes similar as SGOT, SGPT, and peak, along with lipid peroxidation labels. These findings indicate that Butea monosperma flowers effectively suppress both acute and habitual seditious responses( Shahavi & Desai, 2007).

3.8 Anticancer exertion

 Butea monosperma has demonstrated notable anticancer eventuality, particularly against bone cancer, in both in vitro and in vivo studies. Laboratory trials revealed that factory excerpts inhibit the proliferation of bone cancer cell lines and promote apoptosis. Beast studies further showed a significant reduction in tumour growth and volume, along with favourable modulation of biochemical labels linked to cancer progression. These anticancer goods are primarily attributed to bioactive phytochemicals similar as flavonoids, polyphenols, and other secondary metabolites, which retain antioxidant,pro-apoptotic, and cytotoxic parcels. Overall, the findings suggest that Butea monosperma could serve as a promising natural agent for bone cancer operation( Karia et.al., 2018).

3.9 Antidepressant Activity

Butea monosperma has shown promising antidepressant effects in preclinical studies. Methanolic and ethanolic extracts of the plant demonstrate central nervous system–modulating activity, including mood enhancement and reduction of stress-related behaviours in animal models of depression. These effects are likely linked to the presence of flavonoids and chalcones, which may regulate neurotransmitter function. Overall, the findings indicate that Butea monosperma could be a valuable herbal option for managing depressive disorders (Boya et al., 2025).

3.10 Anti-Hyperglycemic Activity

Butea monosperma leaves exhibit significant anti-hyperglycemic effects. Ethanolic extracts, administered at doses of 100–400 mg/kg, reduced blood glucose levels in adrenaline-induced and high-glucose–fed diabetic rabbits in a dose-dependent manner, with the 400 mg/kg dose showing the greatest effect. These actions are attributed to the presence of flavonoids, tannins, phenols, and saponins, which enhance insulin secretion, improve glucose utilization, and inhibit intestinal glucose absorption. These findings support the traditional use of Butea monosperma in the management of diabetes(Ray et al., 2017).
