Chemical analysis and in vitro antioxidant and anticholinesterase activities of essential oils and extracts from different parts of Erica manipuliflora

Abstract

This study reports the chemical composition of essential oils and in vitro antioxidant and anticholinesterase activities of essential oils, hexane, ethyl acetate, methanol, and butanol extracts of aerial, flower and leaves parts of Erica manipuliflora. GC and GC/MS analyses were used for identification of essential oils. Totals of 47 compounds were detected in the essential oils of aerial, flower and leaves parts accounting for 99.99%, 99.88% and 99.97%, respectively. The major components of the aerial, flower and leaves parts of essential oils were Germacren D (14.76%, 15.55% and 13.58%), tau-cadinol (7.53%, 4.11% and 8.96%), caryophyllene oxide (3.92%, 5.17% and 8.55%), βcaryophyllene (7.24%, 5.97% and 7.73%), and α-terpineol (6.85%, 6.14% and 4.18%), respectively. The essential oils of aerial (34.49%) and leaves (37.01%) parts consisted of mainly sesquiterpene hydrocarbons whereas essential oil of flower part (42.58%) included monoterpenoids. The essential oils and extracts were screened for their antioxidant and anticholinesterase activities. The results of activities showed that extracts possessed the highest antioxidant activity while essential oils had the highest anticholinesterase activity. This finding supposes that E. manipuliflora may be considered as valuable natural source with antioxidant and anticholinesterase properties for food, cosmetic and pharmaceutical industries.

In-Vitro Antibacterial Activity and Chemical Composition of Syrian Erica Manipuliflora Essential Oil

“…The other main distinct components in EO of E. manipuliflora collected in full flowering period were Transcaryophellene, Verbenol, β-bisabolene, which represented 7.61, 2.19, 2.15%, respectively, and were absent in the EO of E. manipuliflora collected before flowering period. The percent of verbenol was higher than that recorded by Kuş et al 36 , who found that the verbenol represents 1.17% in the EO extracted from E. manipuliflora flower part.…”

“…The major compound was Germacrene-D, which represented 35.02 and 16.90% in the EOs extracted from aerial parts of this plant in the two growth periods (before flowering and full flowering, respectively). These values were higher than that recorded by Kuş et al 36 (14.76 and 15.55%, in aerial parts and flower part, respectively); followed by tau-cadinol (26.36 and 11.89% respectively in the two growth periods mentioned above). These values were higher than that recorded by Kuş et al 36 which were 7.53 and 4.11% in the aerial parts and flower part, respectively.…”

“…The EO of Erica multipliflora collected before flowering period contained high amounts of Trans-pinocarveol, α-terpineol, βpinene (9.25, 5.59 and 3.65%, respectively). However, Trans-pinocarveol and α-terpineol were higher than that recorded by Kuş et al 36 (5.78 and 6.85%, respectively).…”

“…The EO extracted from plant collected before flowering period characterized by containing β-caryophellene (14.78%); while this component was absent in the EO extracted from the plant collected in the full flowering period. Besides, the percent of β-caryophellene were higher than that recorded in other research, which were 7.24 and 5.97%, in aerial parts and flower part, respectively (Kuş et al 36 ).…”

“…Medicinal and aromatic plants have been used for a variety of purposes worldwide since ancient times [1,2,3]. Nowadays, essential oils are primarily used in cosmetic, pharmaceutical and food industries [4,5,6]. For this reason, plants that can produce essential oils have a strong position as economic products worldwide so the market of essential oils is growing in time [7].…”
