چکیده

Rooibos tea was extracted with boiling water. The aqueous extract was chromatographed in a Diaion HP20 column eluted stepwise with water, 25%, 50% and 75% (v/v) aqueous methanol, and 100% methanol. The water eluate (fraction A) showed an augmenting effect on anti-ovalbumin (anti-OVA) immunoglobulin M (IgM) production in OVA-stimulated murine splenocytes in vitro. Fraction A also showed a strong augmenting effect on interleukin-10 generation in murine splenocytes. Furthermore, continuous ingestion of fraction A was found to increase the anti-OVA IgM level in the sera of OVA-immunized mice.

Ameliorative effect of aspalathin from rooibos (Aspalathus linearis) on acute oxidative stress in Caenorhabditis elegans.

Rooibos leaves and fine stems (Aspalathus linearis; Fabaceae) are increasingly enjoyed as herbal tea, largely in fermented (oxidised) red-brown form, but also in unfermented (unoxidised) green form. Rooibos is rich in antioxidant polyphenols, with the dihydrochalcone, aspalathin, as a major active ingredient. We used Caenorhabditis elegans as model organism to investigate the effect of rooibos ...

Hepatoprotective effect of rooibos tea (Aspalathus linearis) on CCl4-induced liver damage in rats.

Hepatoprotective properties of rooibos tea (Aspalathus linearis) were investigated in a rat model of liver injury induced by carbon tetrachloride (CCl(4)). Rooibos tea, like N-acetyl-L-cysteine which was used for the comparison, showed histological regression of steatosis and cirrhosis in the liver tissue with a significant inhibition of the increase of liver tissue concentrations of malondiald...

Effects of Consumption of Rooibos (Aspalathus linearis) and a Rooibos-Derived Commercial Supplement on Hepatic Tissue Injury by tert-Butyl Hydroperoxide in Wistar Rats

This study investigated the antioxidative effect of rooibos herbal tea and a rooibos-derived commercial supplement on tert-butyl hydroperoxide- (t-BHP-) induced oxidative stress in the liver. Forty male Wistar rats consumed fermented rooibos, unfermented rooibos, a rooibos-derived commercial supplement, or water for 10 weeks, while oxidative stress was induced during the last 2 weeks via intrap...

Modelling the distribution of Aspalathus linearis (Rooibos tea): implications of climate change for livelihoods dependent on both cultivation and harvesting from the wild

Aspalathus linearis (Burm. f.) R. Dahlgren (rooibos) is endemic to the Fynbos Biome of South Africa, which is an internationally recognized biodiversity hot spot. Rooibos is both an invaluable wild resource and commercially cultivated crop in suitable areas. Climate change predictions for the region indicate a significant warming scenario coupled with a decline in winter rainfall. First estimat...
