Chemical Composition and Antimicrobial Activity of Essential Oil From the Flower and Leaf of Caltha palustris L.

The essential oils from flower and leaf of Caltha palustris L. were obtained by hydrodistillation with Clevenger-type apparatus and analyzed by GC-FID and GC-MS. Fifty-two compounds in the oil resulted from flower of C. palustris, representing 95.34% and thirty-six compounds in the oil obtained from leaf of C. palustris, representing 82.4%, were identified. The main components of the volatile oil of the flower part are octadecanol (25.40%), phytol (18.56%), octanol (9.01%) and neophytadien (3.65%) which are alcohols (36.30%) and terpenoids (22.62%) type compounds. It was found that the volatile oil of the leaf part consisted predominantly of hydrocarbons (30.89%) and terpenoid (14.59%) compounds such as heptadecane (10.05%), phytol (8.94%), octadecanol (6.3%), heneicosane (3.03%) and (E)-β- farnesane (1.34%) were major constituents. The antimicrobial activities of the essential oils obtained from flower and leaf parts of C. palustris plant were investigated against 8 Gram positive and Gram-negative bacteria and fungi. It has been determined that essential oils have antimycotic activity against Candida albicans and Saccharomyces cerevisiae (8-14 mm), respectively
