“…Meanwhile, the methanol was the solvent with best results for phenols from pine sawdust, while in almond hulls ethanol was the best extraction solvent (Pinelo et al, 2004). Jung et al (2006) also compared the influence of different solvents and they found out that the ethanol extracts contained higher amounts of total phenolics and flavnoids than water and methanol extracts from wild ginseng leaves. In spite of the fact, that higher amounts of total phenolics were extracted in methanol comparing to ethanol, this is not the case for all the individual phenols.…”

The extractive efficiency of phenolic compounds from plant material is greatly depended on the solvent. In our research, methanol and ethanol were used for taking out the phenols from green walnut fruits. The total phenolics and some individual phenolics, such as gallic, chlorogenic, ellagic, sinapic and protocatechuic acid, (+)-catechin and juglone were detected. Total phenolic contents were determined spectrofotometric but individual phenols using HPLC. Amounts of total phenolics were higher when for extraction methanol was used compare to ethanol, in both cultivars, Elit and Franquette. Similar effect of the solvents was observed in the case some individual phenols, such as juglone, (+)-catechin, gallic, protocatechuic and chlorogenic acid. On the contrary, for ellagic and sinapic acid the extraction was better when ethanol was used compare to methanol.

“…In fact, Pinelo et al [21] reported that methanol was the best extraction solvent for polyphenols from pine sawdust, while ethanol was the best extraction solvent in almond hulls. Similarly, in wild ginseng leaves, the ethanol extracts contained higher amounts of total polyphenols and flavonoids than water and methanol extracts [22].…”

Polyphenols in rinds, membranes and seeds of pomegranates were extracted with acetone, acetone:water (70:30, v:v), methanol, ethanol and water for 12 h at 4C. Gallic acid, punicalin, -punicalagin, -punicalagin and ellagic acid derivatives (EAD) were identified in rind and membrane, while only EAD were identified in seed by HPLC. The rind and membrane contained exceptionally high amounts of polyphenols. Strong correlations were found between antioxidant activity (AOA) and total polyphenol content (TPC) for the extracts of rind (r=0.967), membrane (r=0.976) and seed (r=0.972). Moreover, the highest TPC and AOA were determined in acetone:water (70:30, v:v) extracts. Punicalagins at high amounts in the pomegranate rind and membrane provided the highest AOA and antibacterial activity (ABA). The extracts of rind and membrane showed ABA against Bacillus megaterium and Staphylococcus aureus. Water extracts of rind and membrane may be used as a food additive and preservative due to their high AOA and ABA. Keywords

“…These two extracts were kept in 3.31 µL (2 mg) and 1 mL (2 mg) aliquots. All extracts, BVAc, BVMe, MSAc and MSMe were stored in aliquots at -20ºC to avoid contamination and repetitive freeze-thaw (Jung et al, 2006).…”

Background: Iron accumulation in the liver is customary in pathological conditions associated with oxidative stress. Iron is also an essential element for organisms at its physiological levels. This study was aimed at investigating the antioxidant and hepatoprotective potential of acetone and methanol defatted seed extracts of Bauhinia variegata Linn (Leguminosae) against ferric chloride (FeCl 3 )-induced lipid peroxidation in chicken liver in vitro. Materials and Methods: Antioxidant capacity and hepatoprotective potential of acetone and methanol defatted seed extracts of B. variegata were evaluated using the established in vitro models, FeCl 3 -induced lipid peroxidation in chicken liver homogenate and thin layer chromatography-2,2-diphenyl-1-picrylhydrazyl (TLC-DPPH). Ascorbic acid, and acetone and methanol seed extracts of milk thistle (Silybum marianum) were used as antioxidant and hepatoprotective controls. Results: An overall of 80% acetone and absolute methanol defatted seed extracts of B. variegata [B. variegata acetone extract (BVAc) and B. variegata methanol extract (BVMe)] revealed to possess antioxidant and free radical scavenging capacity, which can protect the liver from FeCl 3 -induced lipid peroxidation in a concentration-dependent manner when compared with controls, ascorbic acid and extracts of milk thistle. At concentrations of 250 µg/mL and 300 µg/mL, thiobarbituric acid reactive species (TBARS) inhibitions were 80.5% and 97.6% for BVAc; and 84% and 98.7% for milk thistle acetone extract (MSAc). At concentration of 300 µg/mL, BVMe and milk thistle methanol extract (MSMe) TBARS inhibitions were 89.0% and 93.8%, respectively. These findings may confirm the presence of antioxidant compounds with hepatoprotective potential in both defatted seed extracts of B. variegata. Conclusion: The findings of this study suggest acetone and methanol extracts of B. variegata defatted seeds may serve as good sources of natural antioxidant and hepatoprotective agents.
