Study Findings
• Analgesic: Analgesic properties of extracts and fractions from Erythrina crista-galli (Fabaceae) leaves: The study describes the analgesic activity of extracts from Erythrina crista-galli leaves in experimental mice models.
• Antimicrobial / Isoflavonoids: Study isolated isoflavonoids coumestrol, genistein and daidzein from the acetone extract of E crista-galli leaves. The compounds showed antimicrobial activity against Bacillus brevis.
• Phomol / Antiinfllamatory: The majority of endophytes isolated from different collections of E crista-galli are species of the genus Phomopsis. Phomol, a novel antibiotic, was isolated from an endophytic fungi from the medicinal plant E crista-galli.
