Antioxidant gallocatechins, dimeric and trimeric proanthocyanidins from sea buckthorn (Hippopha� rhamnoides) pomace

Solvent Free Microwave-Assisted Extraction of Antioxidants from Sea Buckthorn (Hippophae rhamnoides) Food By-Products

“…Sea buckthorn berries are a rich source of many different bioactive compounds that may contribute to the claimed and proven health benefits of sea buckthorn juice and oil. Juice extraction from sea buckthorn berries leads to a residual press cake whose pulp is reported to contain mainly flavones (Rosch et al 2004). Sea buckthorn pomace is a by-product which is produced during sea buckthorn juice extraction, consisting of pulp, seed and skin.…”

Inositols and methylinositols in sea buckthorn (Hippophaë rhamnoides) berries

“…So far most of the compositional studies have concentrated on the fatty acids, phenolic compounds, vitamins, sterols and minerals [15,17,[21][22][23][24][25][26]. The mechanisms behind the widely shown health effects are still largely unknown.…”

Electron spin resonance - A spectroscopic method for determining the antioxidative activity

“…Therefore, they do not contribute to the antioxidative activity of sea buckthorn [53]. A chromatographic fractionation of the sea buckthorn pomace showed a high amount of proanthocyanidins, which also have high antioxidative activites [53,54]. Beside the monomeric fractions (flavan-3-ols), the dimeric, the trimeric, as well as the oligomeric proanthocyanidin fractions showed higher antioxidative capacities compared to vitamin C or Trolox, a vitamin E analogue.…”
