In the present work, we investigated the anti-tyrosinase activity, mechanism and antioxidant
activity of proanthocyanidins (PAs) isolated from Pinus thunbergii needles. The results …

Proanthocyanidins were isolated and purified from fruits of elephant apple (Dillenia indica
Linn.) and their structural and bioactive properties were examined. Bate‐Smith alcoholysis …

The objective of this study was to assess the structure, anti-tyrosinase activity, and
mechanism of proanthocyanidins extracted from Rhododendron pulchrum leaves. Results …

To explore the composition of anthocyanins and expand their biological activities,
anthocyanins were systematically isolated and purified from tubers of Solanum tuberosum …

Fruit stones and pericarps of Litchi chinensis, waste products of the food, were studied as a
source of polymeric proanthocyanidins. The structures of the polymeric proanthocyanidins …

Proanthocyanidins in Chinese bayberry leaves (PCBLs) were qualitatively analyzed. NMR
data suggest that PCBLs are mostly composed of (epi) gallocatechin gallate units. Matrix …

The anthocyanins in the fruits of Rhodomyrtus tomentosa (ACN) were extracted by 1% TFA
in methanol, and then purified by X-5 resin column and C18 (SPE) cartridges. The purified …

Radish anthocyanins were extracted from red radish. The total anthocyanins content (TAC)
of the extracts under different extractants was optimized to reach the optimal condition. XAD …

Proanthocyanidin oligomers with different degrees of polymerization were isolated from
Saskatoon berries (Amelanchier alnifolia) by means of gel adsorption and normal-phase …
