Investigation of Recovery of Volatiles of Bidens tripartita L. Using Solid-Phase Extraction Trap in Supercritical Fluid Extraction

Abstract

Recovery of Bidens tripartita L. volatiles using supercritical CO 2 extraction with solid-phase trap was performed in this study. Three aspects were under investigation: the impact of solvent (heptane, methanol or acetonitrile) applied to rinse the analytes from the trap; the impact of the amount of plant material used for extraction; the release of volatiles from plant matrix using multiple extraction. α-Pinene, p-cymene, β-ocimene, and β-elemene were predominant in all extracts prepared in different ways. β-ocimene was the major compound (40-46%) in all extracts regardless of the solvent used. No significant difference in amount of α-pinene was observed when different trap desorption solvents were used, while heptane desorbed significantly higher amounts (12-31%) of other compounds. The volatile composition showed both qualitative and quantitative differences when different amounts of sample material were used. The extraction extent of the main compounds varied between first and repeated extractions.

Influence of Modifiers, Extractants, and Trappers on Lipid Composition with Liquids in Standard State Extraction, Supercritical Fluid Extraction and Trapping by Supercritical Fluid Extraction, Part II

“…Solid-phase trapping is extensively used for polychlorinated polyaromatic hydrocarbons [43] and petroleum hydrocarbons [44]. Studies of solid-phase extraction, trapping of volatile oils have also been published [45]; however, to my knowledge, there is no description of the use of solid-phase trapping in SFE of lipids, including FFAs and the results. It would be interesting to investigate the influence on the composition of FFAs by trapping material in SFE solid-phase trapping.…”

Accumulation of fluorides by plants of Bidens tripartita L. species on the territories with endemic fluorine deficit

“…Попередні наші дослідження рослин виду Bidens tripartita L. засвідчили їх здатність концентрувати елемент Флуор із високою біологічною активністю [10], що є актуальним для населення Чернівецької області, ендемічної за низьким вмістом Флуору в навколишньому середовищі [1,15]. Окрім того, до складу рослин виду Bidens tripartita L. входять біологічно активні речовини, різні за складом і хімічною будовою: ефірна олія, сапоніни, вітамін С, дубильні речовини, вуглеводи, органічні кислоти, кумарини, флавоноїди, віскоза, ліпіди, каротин, слизи, гіркоти [5,8,9,16]. Мінеральний склад рослинної сировини (31-34 %) представлений мікроелементами K, Ca, Mg, Fe, Mn, Cu, Zn, Co, Cr, Al, V, Se, Ni, Sr, Pb, B, з яких рослина концентрує Se, Mn, Zn, Cu [7].…”

A micelle mediated extraction as a new method of obtaining the infusion of Bidens tripartita

“…The main components of the essential oil obtained from the roots of B. tripartita by hydrodistillation were α-pinene, β-bisabolene, p-cymene, hexanal, linalool, p-cymene-9-ol, β-elemene, 2-pentylfuran, and silphiperfol-6-ene (Tomczykowa et al, 2011). In turn, α-pinene, p-cymene, β-ocimene, and β-elemene are predominant in extracts prepared by supercritical CO 2 extraction with solid-phase trap (Kaškonienė & Maruška, 2015).…”
