“…SFE at the temperature of 60 °C and pressure of 152 bar with the addition of 12% ( v / v ) ethanol resulted in 2 times lower TPC (around 5% of dry weight). In some cases, SFE and SFE-PLE provide similar TPC values as was proved by Kraujaliene et al [ 166 ] on the example of goldenrod ( Solidago virgaurea ) extraction with TPC around 169–185 mg GAE/g. The combination of acetone with either 70 °C or 140 °C in PLE and carbon dioxide with 70 °C in SFE-PLE method were used.…”

The Application of Supercritical Fluid Extraction in Phenolic Compounds Isolation from Natural Plant Materials

The separation of phenolic compounds by supercritical fluid extraction has been widely studied throughout the last two decades. This is evidenced by a number of publications and articles. Supercritical fluid extraction (SFE) has become thus the effective method of separating the mentioned group of compounds. On the other hand, SFE is a beneficial approach in plant waste materials utilization and reduction of environmental burdens caused by the wastes. The aim of the study is to gather and systematize available information on the phenolic compounds separation that have been reported so far as well as to evaluate whether there is one optimal supercritical fluid extraction method for the phenolic compounds.

“…Among the flavonoids, rutin, quercetrin, astragalin, nicotiflorin, biorobin, and narcissin have been considered "the most representative" [64], and they are accompanied by their aglycons [49,95]. More recently, flavanones aglycones and glycosides have also been detected and quantified in the different parts of the plant: eriodictyol (the largest amount in the flowers, followed by leaves and then stems, mostly as glycosides), naringenin (similar quantitative distribution in flowers, leaves, and stems, mostly as glycosides), and very small amounts of hesperitin (not assessed separately in each aerial parts) [102].…”

“…As mentioned above, hyperoside is considered the key flavonoid by the European Pharmacopoeia [83]. However, in one paper quercitrin was the major phytochemical from a quantitative standpoint [95], whereas other sources reported rutin as the dominant flavonoid [59,60] (a mean content 196.42 mg100 g-1 reported by [59]). A qualitative and quantitative comparative study of flavonoids from extracts of four Solidago spp.…”

Solidago virgaurea L. (European goldenrod, Woundwort), Asteraceae, is a familiar medicinal plant in Europe and other parts of the world, widely used and among the most researched species from its genus. The aerial parts of European goldenrod have long been used for urinary tract conditions and as an anti-inflammatory agent in the traditional medicine of different peoples. Its main chemical constituents are flavonoids (mainly derived from quercetin and kaempferol), C6-C1 and C6-C3 compounds, terpenes (mostly from the essential oil), and a large number of saponin molecules (mainly virgaureasaponins and solidagosaponins). Published research on its potential activities is critically reviewed here: antioxidant, antiinflammatory, analgesic, spasmolitic, antihypertensive, diuretic, antibacterial, antifungal, antiparasite, cytotoxic and antitumor, antimutagenic, antiadipogenic, antidiabetic, cardioprotective, and antisenescence. The evidence concerning its potential benefits is mainly derived from non-clinical studies, some effects are rather modest, whereas others are more promising, but need more confirmation in both non-clinical models and clinical trials.

“…Natural products have been used in traditional medicine, foods, and cosmetics since ancient times. Plants biosynthesize thousands of various secondary metabolism products, among them valuable phytochemicals possessing antioxidant, antimicrobial, and many other health beneficial properties [1,2]. Considering vast biodiversity in the Plant Kingdom, bioguided investigation and valorization of less studied species remain an important topic for modern biosciences, particularly in order to discover new valuable ingredients and natural molecules for foods, nutraceuticals, pharmaceuticals, and cosmeceuticals.…”

Mangiferin Rich Products from Aphloia theiformis (Vahl) Benn Leaves: Extraction, Fractionation, Phytochemical Characterization, and Antioxidant Properties

Aphloia theiformis is traditionally used in Mauritius, Madagascar, and Reunion Island for treating several diseases. In this study, various extraction solvents and schemes were applied for the recovery of antioxidant rich fractions from the leaves of A. theiformis. The products were evaluated for their antioxidant capacity using well known in vitro assays. Major compounds were characterized by UPLC–QTOF–MS. Hydrophilic extracts of A. theiformis demonstrated strong antioxidant properties, which are comparable with the synthetic antioxidant Trolox. UPLC analysis confirmed mangiferin as the main secondary metabolite of A. theiformis. Tormentic and hydroxytormentic acids as well as their isomers were also abundant in A. theiformis extracts and fractions, while their amounts were determined for the first time. The most potential extract was further separated into the fractions by liquid-liquid extraction and by precipitation at low temperature. Antioxidant capacity and composition of secondary metabolites of derived fractions were determined. Some of the fractions possessed remarkable antioxidant capacity, comparable to pure mangiferin. The results obtained reveal high potential of A. theiformis for recovery of natural antioxidants and other bioactive phytochemicals, particularly mangiferin.
