“…The MIC value of 100-200 μg/mL is generally acceptable for plant materials [200]. Although the extracts of the parts of the genus Senna could not reach such MIC values, when the bioactive compounds are isolated from the extracts, MIC values decrease, and the antimicrobial properties increase [201]. Some of these bioactive components include stigmasterol, beta-sitosterol, kaempferol, luteolin, santal, alatonal, aloe-emodin, alquinone, chrysophanol, emodin, physcion, rhein, alarone, benzoquinone, coumarin, ellagitannin, naphthalene, phenolic acid, purine, xanthone, and cassine [202].…”
