• Bauhinia racemosa
• Aerial parts
• Antimicrobial activity
• Antioxidant activity
• Chemical content

Methanol 70% extract of Bauhinia racemosa aerial parts was tested for antimicrobial activity against different bacterial and fungal strains and for antioxidant activity and also total content of polyphenols with phytochemical analysis of the extract was determined. The results have showed that the extract has a significant antimicrobial activity, it inhibited the growth of Bacillus subtilis and also it was highly active against Candida albicans suggesting that it can be used in the treatment of fungal infections. The extract has a good antioxidant activity, it has shown high values of the trolox equivalent antioxidant capacity and polyphenol content while it has shown a lower value of oxygen radical absorbance capacity. Phytochemical analysis has shown that it has interesting phytochemical bioconstituents, include flavonoids, tannins and others, and the deep phytochemical study results in the isolation of methyl gallate, gallic, kaempferol, quercetin, querection 3-O-alpha-rhamnoside, kaempferol 3-O-beta-glucoside, myricetin-3-O-beta-glucoside, querection-3-O-rutinoside (Rutin). All compounds were identified by different spectroscopic analyses (UV, H-1-NMR, C-13-NMR) and Mass Spectrometry (MS).
