چکیده
BACKGROUND Ayurvedic text reports suggested Lannea coromandelica is used in various microbial origin disorders like dysentery, sore eyes and leprosy, genital wounds. OBJECTIVE The present study was designed to investigate the antimicrobial effect of L. coromandelica Houtt. Merrill. (Anacardiaceae) on microbes which cause female reproductive tract infection. MATERIALS AND METHODS Ethanolic and aqueous bark extract (Ext.) of L. coromandelica were screened against strains of Streptococcus pyogens, Staphylococcus aureus, and Candida albicans. Antimicrobial assay had been done with agar well diffusion method. RESULTS Ethanolic extracts [100% (16 mg), 75% (12 mg) and 50% (8 mg)] of L. coromandelica exhibited zone of inhibition (ZI) 19.21 mm, 18.45 mm, 16.41 mm and 18.12 mm, 17.35 mm, 16.35 mm against S. aureus and S. pyogens, respectively. However, only 100% and 75% ethanolic extract showed (ZI-19.18 mm, 16.29 mm) activity against C. albicans. Nevertheless, aqueous extract (100%) showed higher antifungal activity (ZI-16.97 mm). Ciprofloxacin and amphotericin B were used as a standard drugs in the present study. CONCLUSION The results demonstrated that L. coromandelica Houtt. Merrill. have antibacterial activity against S. pyogens, S. aureus and antifungal property against C. albicans. Our findings corroborate the ethnobotanical use of L. coromandelica in traditional medicine system (Ayurveda) of India.

The global burden of bacterial infections is very high and has been exacerbated by increasing resistance to multiple antibiotics. Antibiotic resistance leads to failed treatment of infections, which can ultimately lead to death. To overcome antibiotic resistance, it is necessary to identify new antibacterial agents. In this study, a total of 662 plant extracts (diverse parts) from 222 plant spe...
