“…Then, the bark, sapwood and heartwood were separated, so as to be treated apart from one another. All specimens were cut by hand in small wood parts, which were trimmed by a mill into wood dust, in order to be used for the determination of the extractives, acidity (pH) and inorganic components (ash) (Picture 1) (Chavenetidou et al, 2020).…”

“…After the extraction procedure, the specimens were removed from the Soxhlet device and left at room conditions of temperature and humidity (approximately 25 0 C and 55%) for 24h, before they were put in the oven at 103 ± 2 0 C for another 24 hours, until the total drying of the material. Finally, they were weighed so as to determine the dry weight of the extracted material, after the removal of the extractives (Chavenetidou et al 2020).…”

The objective of the present study was the determination of the extractives, acidity and ash content of three different provenances of Cupressus semprevirens wood. The specimens were collected from the sapwood, heartwood, bark and needles of the trees. The quantitative determination of the extractions was performed with two different solvents, water and ethanol.The results showed no significant differences among the three provenances (P1, P2 and P3), except for the oldest, which also had the highest extract content, a fact that is attributed to the growth of the trees without competition. Furthermore, the needles and the bark, had, in all cases, the highest ash content, while heartwood appeared to have higher contents of extractives, compared to sapwood.

The Effect of Traditional and Cyclodextrin-Assisted Extraction Methods on Trifolium pratense L. (Red Clover) Extracts Antioxidant Potential

et al. 2022

Red clover is the subject of numerous studies because of its antioxidant properties, the positive influence of isoflavones on the health, and its potential use in the prevention and treatment of chronic diseases. The right excipients, such as cyclodextrins, can increase the profile of valuable phenolic compounds in extraction media to obtain rich in antioxidants, extracts that can be used in nutraceuticals production. The aim of this study was to investigate and compare the total phenolic content, flavonoid content, and antioxidant activity of red clover aerial parts, aqueous and ethanolic extracts prepared using traditional and cyclodextrins-assisted methods. The antioxidant activity of the extracts was established using ABTS, DPPH, FRAP, and ABTS-post column methods. It was determined that cyclodextrins significantly increased total phenolic content (compared with control)—using β-cyclodextrin 20.29% (in aqueous samples); γ-cyclodextrin 22.26% (in ethanolic samples). All the samples prepared with excipients demonstrated a strong relationship between total phenolic content and DPPH assay. Study showed that for extraction with water, the highest amounts of phenolic compounds, flavonoids and antioxidant activity will be achieved with β-cyclodextrin, but extractions with ethanol will give the best results with γ-cyclodextrin. Therefore, cyclodextrins are a great and safe tool for obtaining rich, red clover flower extracts that are high in antioxidant activity, which can be used in the pharmaceutical industry for nutraceuticals production.
