In the present study, Achillea atrata L. and A. millefolium L. were compared for the first time with regard to their phenolic compound profile and antioxidant activity by applying the 2,2-diphenyl-picryl hydrazyl radical assay. For this purpose, aerial plant parts were consecutively extracted with solvents of increasing polarity (dichloromethane, n-butanol, ethyl acetate), revealing that the A. atrata ethyl acetate fraction showed the highest antioxidant activity with an IC50 value of 12.2 ± 0.29 µg/mL compared to 17.0 ± 0.26 µg/mL for A. millefolium. Both species revealed the presence of luteolin, apigenin, centaureidin, and nevadensin exclusively in this most polar fraction, which are known as effective 2,2-diphenyl-picryl hydrazyl radical scavengers. The antioxidant capacity of the aforementioned fractions strikingly correlated with their total phenolic contents, which was highest in the ethyl acetate fraction of A. atrata. Characterization of the metabolite profiles of both Achillea species showed only marginal differences in the presence of key compounds, whereas the concentrations of individual compounds appeared to be species-specific. Our results suggest that A. atrata, based on its compound pattern and bioactivity characteristics, has similar qualities for phytotherapy as A. millefolium. 相似文献

The herbal parts of Arischrada korolkowii (Regel et Schmalh.) Pobed. (Lamiaceae) growing in Uzbekistan were hydrodistillated to yield 1.1% of essential oil. The essential oil was analyzed by GC/MS. Eighty eight compounds were characterized representing 98% of the essential oil with 1,8-cineole (29.3%), camphor (9.8%), -caryophyllene (8.5%), bornyl acetate (7.7%), caryophyllene oxide (7.2%), and borneol (5.6%) as the main constituents. 相似文献

The production and the composition of the compounds (mono-, sesquiterpenes and acetylenic thiophenes) obtained by the steam distillation of Tagetes patula L. have been investigated. The volatile oil was produced by steam distillation. GC was carried out on three types of stationary phase using flame ionization and mass selective detection. Percentage data were calculated by the area normalization method with very good repeatability (RSD below 5%). Oils from flower-heads were rich in β-caryophyllene (53.5%) and the leaves contained terpinolene in high concentration (21.1%). The main volatile component of the hairy roots and intact roots was 5-(3-buten-1-ynyl)-2,2'-bithienyl (BBT) yielding 28.5% and 44.0% in the oils. Three new minor constituents were identified as α-gurjunene, β-caryophyllene and (E)-β-farnesene. A flash chromatographic method was developed for the isolation of thiophenes from a solvent extract of intact roots. The collected fractions were screened by TLC and analyzed by GC-MS. Three thiophene fractions were obtained containing BBT, 5-(4-acetoxy-1-butynyl)-2,2'-bithienyl (BBTOAc) and 5-(4-hydroxy-1-butynyl)-2,2'-bithienyl (BBTOH). 相似文献
