“…Although the genotype is a vital factor that affects the types and contents of chemical substances in plants, in contrast to J. regia, relatively few studies have investigated the phenolic compounds constituent in J. sigillata. Only four types of galloyl glucosides were detected in the leaves, [8] whereas gallic acid (GA), ellagic acid, tannic acids, (+)-catechin, (−)-epicatechin, (+)-catechin(4 → 8″)-(+)-catechin, (+)-catechin(4α 65 → 658)-(+)-catechin, five types of galloyl glucosides, and 9 α-tetralone derivatives were found in green husks. [9][10][11][12] GA, ellagic acid, pedunculagin, 2,3-O-4,4′,5,5′,6,6′-hexahydroxydiphenoyl-(α/β)-glucose, and six types of galloyl glucosides were found in stem bark.…”

The phenolics content and antioxidant activity of walnut (Juglans sigillata Dode) green husks were analysed during different stages of development. Contents of total phenolics and total flavonoids decreased from April 25th to June 7th, then increased during June and July, and decreased again at the beginning of August. Thirteen types of phenolic compounds were identified using HPLC of which juglone had the highest content. Because of seasonal variations, the trends of different phenolic compounds were different. Contents of both total phenolics and total flavonoids were strongly correlated with antioxidant activity; however, compared with totals, less significant correlations were observed between individual phenolic compounds and antioxidant activities.
