Volatile Oil Constitution and Microbicidal Activities of Essential Oils of Coriandrum sativum L.

Abstract

Objective: To detect the essential oil constituents of herb and seeds of Coriandrum sativum L. and their microbicidal activities against six bacteria and six fungi. Materials and methods: Herb and seed oils of C. sativum were extracted in a Clevenger apparatus. Components were detected by gas liquid chromatography (GLC) and the microbicidal activities were analysed by disk diffusion method. Results: Monoterpenoids and phenols were detected from herb oil but only monoterpenoids could be identified in the seed oil. Herb oil showed highest activity against Candida albicans but seed oil have significant activity against Xanthomonas campestris, C. albicans and Colletotrichum musae. Conclusion: The microbicidal activities of these essential oils may be due to the terpenoids present in them.
