Chemical Compositions of Achillea sivasica: Different Plant Part Volatiles, Enantiomers and Fatty Acids

Abstract

In the present work, Microsteam distillation -Solid phase microextraction (MSD-SPME) and hydrodistillation (HD) techniques were applied to obtain volatiles from Achillea sivasica, an endemic species from Turkey. GC-FID and GC/MS analysis revealed that 1,8-cineole (22.1%) and -pinene (9.3%) were the main constituents of the hydrodistilled flower volatiles. (Z)--Farnesene (23.9%), decanoic acid (10.1%), eudesmol (8.0%), tricosane (7.3%) and hexadecanoic acid (7.2%) were the main volatiles obtained from flowers by MSD-SPME. The leaf volatiles obtained by HD contained camphor (9.0%), -pinene (6.9%), 1,8-cineole (6.7%), -pinene (6.7%) and-bisabolol (6.6%) as the main constituents while the leaf volatiles obtained by MSD-SPME technique were rich in (E)-geranyl acetone (10

Evaluation of Phytochemical Compositions and Biological Properties of Achillea gypsicola at Different Phenological Stages

“…Previous researches indicated that volatile oils extracted from some Achillea species were represented by the high content of monoterpene oxygenated . The percentages of sesquiterpene oxygenated ranged from 0.33 to 0.79 %, sesquiterpene hydrocarbons were represented by 0.24 to 4.81 %.…”

“…When all periods were compared, the accumulation of menthone and menthol were highest in the samples harvested at 8 pm (22.78 % and 20.55 %, respectively). Many studies conducted previously in medicinal plants have shown that factors such as, genetics, environmental conditions, postharvest treatments, harvesting times and phenological stages are effective in the change of volatile oil composition …”

“…It was revealed that essential components of volatile oils of this genus are phytochemicals such as borneol, chamazulene, 1,8‐cineole, santolina alcohol, ascaridole, iso‐ascaridole, p ‐cymene, chrysanthenone, trans ‐carveol, neoiso‐dihydrocarveol acetate and filifolone with a significant variation of these components among Achillea species in previous researches . This variation in bioactive components changes depending on genetics and environmental factors, harvesting times and phenological stages . For example, while accumulation of piperitone, thymol and carvacrol increased at 100 % flowering stage, accumulation of 1,8‐cineole and germacrene D decreased in the stage in A. aucheri …”

Volatiles and fatty acid analyzes of Tripleurospermum decipiens (Fisch & C. A. Mey) Bornm and investigation of the extracts for antimicrobial and enzyme inhibitory activities

“…The extraction of fatty acids from T. decipiens has been carried out using the "Fatty Acid Extraction" Kit. Methyl esters of the fatty acids were obtained with Boron trifluoride-methanol solution and analyzed by GC-FID/MS (28). In vitro AChE and -amylase enzyme inhibitions of the extracts were determined by spectrophotometric method with Ellman's and KI/I2 reagents, respectively.…”

Morphology, anatomy, palynology and conservation status of Achillea ketenoglui H. Duman

“…Studies were carried out on Achillea taxa by both local and foreign workers on different aspects, mostly on chemical components and their importance for anticancer, antimicrobial etc. (Tabanca et al 2016, Haliloğlu et al 2017, Demirci et al 2018, Özek et al 2018. Studies on morphology, anatomy and palynology of A. ketenoglui H. Duman are still limited (Arabacı 2006, Akyalçın et al 2009, 2011, 2014, Grytsyk 2016, Dauti et al 2017).…”
