“…Other major phenolic compounds present in rooibos include �avones (orientin, isoorientin, vitexin, isovitexin, luteolin, and chrysoeriol), �avanones (dihydro-orientin, dihydro-isoorientin, and hemiphlorin), and �avonols (quercetin, hyperoside, isoquercitrin, and rutin) [52,[57][58][59][60]. Phenolic acids, lignans, �avone diglycosides, (�)-catechin, a phenylpyruvic acid glycoside, the �avonol quercetin-3-O-robinobioside, and the coumarins, esculetin and esculin have also been identi�ed [52,[61][62][63][64].…”

ere is a growing interest in natural plant-based remedies as a source for commercial products. Around 80% of the South African population use traditional medicines to meet their primary health care needs; however, only a few South African medicinal plants have been exploited to their full potential in terms of commercialization. e opportunity for bioprospecting of plant compounds for novel pharmaceuticals remains largely untapped. Certain renowned medicinal plants of international acclaim including buchu and rooibos are currently contributing to local enterprise; however, other exciting opportunities exist for commonly used plants which have not yet reached the international arena. is paper focuses on the key research and development contributions of 10 commercially important medicinal plants of South Africa. �raditional uses, scienti�c validation, commercialisation developments, as well as both potential opportunities and setbacks are discussed.

“…As such, this review will principally focus on literature describing the defined bioactivities of enriched or purified Cglycosyl flavonoid fractions only. Additionally, direct antioxidant effects described in vitro will be omitted due to the lack of significant correlation between in vitro antioxidant capacity and in vivo plasma antioxidant capacity for some tested C-glycosyl flavonoids (Breiter et al, 2011;Hollman et al, 2011;Mladenka et al, 2010).…”

“…Cucumis sativus L. contains a good number of C-glycosides and O-glycosides flavonoids isomers as Table 1 shows. The presence of C-glycoside flavonoids has been described in many Cucurbitaceae species (Hertog et al, 1992) -120], in addition to the fragment ions at m/z 369.0614 (aglycone + 83) and 399.0715 (aglycone +113) which represent the aglycone plus the residues of the sugars that remained linked to it and therefore indicated the aglycone as a trihydroxyflavone (luteolin) (Breiter et al, 2011). On the basis of these MS and MS/MS spectrum data peak 14 was tentatively identified as luteolin-6, 8-di-Chexoside.…”
