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

In this study, total phenols (TP) and proanthocyanidins (PAs) in the leaves and branches of
Cinnamomum camphora were investigated, and isolated PAs were determined using …

In this study, the structure of proanthocyanidins purified from cherimoya (Annona squamosa)
pericarp was analyzed by ESI-QTOF-MS and HPLC analyses. The result indicated that these …

Proanthocyanidins were purified from avocado (Persea americana) fruit, and their structures
were analyzed by matrix-assisted laser desorption/ionization–time-of-flight mass …

This study investigated the structure, antioxidant activity, antityrosinase activity and
mechanism of proanthocyanidins from mung bean seed [Vigna radiata (L.) Wilczek]. The …

This study aimed to investigate the structural features, antioxidant activity, tyrosinase
inhibitory effect, and mechanism of proanthocyanidins from leaf and fruit of Leucaena …

Fruit pericarp of Clausena lansium (Lour.) Skeels, a food waste, was selected as a raw
material for proanthocyanidins. The proanthocyanidins' structures were integrally analyzed …

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

Proanthocyanidins were isolated from fruit stone of Chinese hawthorn (Crataegus
pinnatifida Bge. var. major NE Br.). Their structures were analyzed and elucidated by …

The inhibitory effects of nobiletin and hesperidin from citrus peel crude extracts on
tyrosinase diphenolase activity are evaluated. IC50 of nobiletin and hesperidin is 1.49 mM …
