inhibitions of proanthocyanidins (PACs) from karamatsu (Larix sp.) bark, acacia Morishima …

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

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

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 …

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

In this study the structural features, antioxidant, and tyrosinase inhibitory activities of
proanthocyanidins in leaves of two tea cultivars, namely Huangjingui and Qilan, were …

From the methanolic-soluble extract of the wood of Artocarpus heterophyllus, four new
flavones, artocarmins A–D (1–4), and three new chalcones, artocarmitins A–C (5–7), have …

In our efforts to find new tyrosinase inhibitory materials, we investigated 44 Indonesian
plants belonging to 24 families for tyrosinase inhibitory activity. The extracts of 5 Artocarpus …

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 order to find new tyrosinase inhibitors and the effects of prenyl residue on flavonoid
molecules, eight prenylated and three synthetic vinylated flavonoids were examined on their …
