The steviol is an aglycone and the stevioside is derived from steviol by glycosylation.
The chromatographic properties of compound IV showed that it was an aglycone.
The adulterated ginkgo products analysed by us contained genistein, quercetin and kaempferol in free aglycone form, so if Styphnolobium japonicum were indeed the adulterant, the extract would likely have undergone processing leading to the hydrolysis of the flavonoid glycosides.
Many studies have investigated the protective effects of oleuropein and hydroxytyrosol against cell injury, but few have investigated the protective effects of oleuropein aglycones 3,4-dihydroxyphenylethanol-elenolic acid (3,4-DHPEA-EA) and 3,4-dihydroxyphenylethanol-elenolic acid dialdehyde (3,4-DHPEA-EDA).
Each aglycone fragment generated from GalG2CNP by amylase hydrolysis was examined with a Shimadzu SPD-M6A HPLC equipped with a Tosoh TSKgel ODS-120T (4.

Here, we observed that at 100 nM, GTDF completely protected osteoblasts from Dex or MP-induced loss of cell viability whereas two different analogs of quercetin--quercetin aglycone and rutin (quercetin 0-rhamnoside)--were ineffective, suggesting that GTDF was a potent naturally occurring quercetin in promoting osteoblast viability.
18[beta]-Glycyrrhetinic acid (GA) is an aglycone of glycyrrhizin that consists of GA plus 2 molecules of glucuronic aids (Fig.
Further, dietary flavonoids generally exists in a form of [beta] -glycoside (glycone form) in nature, and in most cases, they are hydrolyzed to their aglycone form while eliciting their physiological effects in vivo (Walle et al.
1a), the aglycone of diosmin, has also been shown to possess antibacterial activities against Helicobacter pylon (Bae et al.
Consistent with that result, some researchers reported that the aglycone part of phenylethanoid glycosides was essential for the potent activity on inhibitory cytotoxicity while 3, 4-dihydroxyl group could also improved the activity (Pan 2011).
