Journal of natural medicines, 64(4), 402-408 (2010-05-18)
The antinociceptive properties of some fractions and two pure compounds, conocarpan and orientin, obtained from P. solmsianum leaves were investigated in several models of pain in mice. The results indicated that this plant exhibits a promising antinociceptive profile, as it...

Journal of the science of food and agriculture, 92(2), 274-282 (2011-07-23)
The effects of citric and ascorbic acids on the stability of aspalathin in rooibos (Aspalathus linearis) ready-to-drink (RTD) formulations containing fermented rooibos extract (FR), aspalathin-enriched green rooibos extract (GR) and aspalathin-enriched green rooibos extract ascorbic acid solubilisate (GR-solubilisate) were investigated...

From sugarcane juice, a flavone, identified by spectroscopic methods as tricin-7-O-beta-(6''-methoxycinnamic)-glucoside, was isolated, in addition to orientin. The tricin derivative was shown to have antioxidant activity higher than Trolox by means of the DPPH assay and lower by the beta-carotene/linoleic...
