“…In 1982, the maceration technique was applied by Ungsurungsie and Suthienkul (1982), whereby water was used as the solvent. Maceration is a simple and commonly used procedure in research on herbal extract, whereby the extracted material becomes softened by soaking in a liquid [105]. The study used two conditions for the dried rhizome extraction processes.…”

“…In 1997, Dai et al (1997) used another conventional method called percolation to extract about 192 g from the entire plant. Percolation is a continuous process in which the fresh solvent slowly passes through an extracted material to extract a particular substance into the solvent [105]. The extraction solvent in this procedure was dichloromethane in methanol (MeOH-CH2Cl2) at a 1:1 ratio.…”

“…The conventional extraction methods, such as maceration, percolation and soxhlet extractions, have been employed for decades, but it is not economical because of relatively large quantities of solvent and the required long extraction times [ 18 ]. To reduce the time of extraction, many measures have been investigated, either separately or combined.…”

Novel Extraction Method Using Excipients to Enhance Yield of Genistein and Daidzein in Trifolium pratensis L.

2021

Isoflavones can be found in different chemical forms, but the health beneficial effects mainly appear in their free forms—aglycones. Their yield in red clover (Trifolium pratensis L.) extracts differs due to different extraction and hydrolysis methodologies. The main aim of this study was to obtain the highest yields of daidzein and genistein from red clover blossoms through the various extraction and hydrolysis methods and to increase their quantities using additional excipients. Extracts were obtained by ultrasound-assisted, heat-reflux and maceration methods combining them with acidic, alkaline, and thermal hydrolysis. Using ultrasound-assisted extraction with optimal conditions and heat-reflux method highest yields of isoflavones were obtained in UTE510 (393.23 ± 19.66 µg/g daidzein and 171.57 ± 8.58 µg/g genistein); UTE530 (415.07 ± 20.75 µg/g daidzein and 150.57 ± 7.53 µg/g genistein) and HNE5 (432.30 ± 21.61 µg/g daidzein and 154.50 ± 7.72 µg/g genistein) samples. These conditions were used with excipients: magnesium aluminometasilicate, croscarmellose sodium, sodium carboxymethyl starch and vinylpyrrolidone-vinyl acetate copolymer. This is the first study reporting the ability of the vinylpyrrolidone-vinyl acetate copolymer to promote solubilization and availability of active compounds from a herbal extract, resulting in enhanced isoflavones yield. The results of the present study showing increased solubility and availability provided by the vinylpyrrolidone-vinyl acetate copolymer suggest that this preparation could in principle also reduce variability due to limited water solubility of isoflavones.

Phytochemical Profiling, Antioxidant and Anti-Inflammatory Activity of Plants Belonging to the Lavandula Genus

2022

Lavender is a valuable medicinal plant belonging to the Lamiaceae family. Currently 39 species are known, but only Lavandula angustifolia is a pharmacopoeial raw material. Lavender has a long history of medicinal use and mainly exhibits antioxidant, anti-inflammatory, sedative, antidepressant, spasmolytic, anticholinesterases, antifungal and antibacterial properties. Used internally, it relieves symptoms of mental stress and insomnia and supports digestion. Topical use of lavender in aromatherapy, neuralgia and antiseptics is also known. The constant interest in lavender, and in particular in Lavandula angustifolia, in the field of medicine and pharmacy is evidenced by the growing number of publications. In view of so many studies, it seems important to review traditional and modern extraction techniques that determine the chemical composition responsible for the antioxidant and anti-inflammatory effects of various extracts from the species of the Lavandula genus.
