(37), daidzein, genistein, daidzin, quercetin, eriodictyol, luteolin, genistin
, and naringenin flavonoids were determined in all the peanut samples.

Quantitation of genistein and genistin
in soy dry extracts by UV-VisibIe spectrophotometric method.
In this paper, MSPD has been successfully used for the extraction of the isoflavones daidzein, genistein, and glycitein, as well as their glycosides daidzin, genistin
, and glycitin, respectively, from different defatted soybean flours.
It has been previously demonstrated that Portulaca oleracea contains flavonoids such as kaempferol, myricetin, luteolin, apigenin, quercetin, genistein, and genistin
odorifera species in Haian, China, formononetin (4), genistein (15), and their glycosides (genistin
and formononetin-8-C-apiosyl(1-6)-glucoside) were detected, and the authors suggested that matrix solid-phase dispersion using titania column (MSPD) was used to elute high concentration flavonoid aglycones first with 90% acetonitrile and 10% water containing 100 mM ammonium acetate buffer, followed by eluting trace flavonoid glycosides with 20% acetonitrile and 80% water containing 1% trifluoroacetate .
Only one compound was noted to decrease in either tissue, that is, sebacate (p-value = 0.0071; q-value = 0.3349) and genistin
(p-value = 0.0323; q-value = 0.9859) in roots and leaves, respectively.
Twelve isoflavone forms have been reported in soybeans, including three aglycones: genistein, daidzein and glycitein and their respective 7-O-[beta]-D-glucosides (genistin
, daidzin and glycitin), 6"-O-malonyl-7-O-[beta]-D-glucosides (malonylgenistin, malonyldaidzin and malonylglycitin) and 6"-O-acetyl-7-O-[beta]-Dglucosides (acetylgenistin, acetyldaidzin and acetylglycitin (Shao et al., 2009).
The phytochemical analyses have reported the presence of various isoflavonoids of high antioxidant properties including daidzin, genistin
, tectoridin, and puerarin in P.
Rutin, quercetin, kaempferol, isorhamnetin, genistein, and genistin
were used as reference compounds and purchased from ChromaDex (Irvine, USA).
