Aim To study the glycosides of the stems and leaves of the goose genus Peach (Schefflera kwangsiensis). Methods The compounds were separated and purified by silica gel column chromatography and gel column chromatography. The structures of the compounds were identified by spectral analysis and physicochemical properties. Results Ten compounds were isolated from the peach leaves and identified as wild-type guagoside C (1), 3-O-β-D-glucopyranosyl-ivyrosine-28-O- (1 → 4) -β-D-glucopyranosyl- (1 → 6) -β-D-glucopyranoside (2), 3-O-β-D-xylopyranose (I → 4) -O-β-D-glucopyranosyl- (1 → 6) -O-β-D-glucopyranosyl- Glucosyl glucoside (3), Ericaerus B (4), 3-O-β-D-xylopyranosyl- (1 → 3) -O-α-L-rhamnopyranosyl- 1 → 2) -O-α-L-arabinopyranosyl-24-β-D-glucopyranosyl - (1 → 6) -O-β-D-glucopyranoside (5), 3-O- [O-arabinopyranosyl- (1 → 4) 1 → 3) -O-rhamnopyranosyl- (1 → 2) -Aranopyranosyl] -oleic acid-O-rhamnopyranosyl- (1 → 4) -O-β Glucopyranosyl- (1 → 6) -β-glucopyranosyl ester (6), Erica glycosides G (7), 3-O- [O-arabinopyranosyl- (1 → 4) (1 → 3) -O-Rhamnopyranosyl- (1 → 2) -Aranopyranosyl] iv) (8), 3-O-β- Graphene (1 → 4) -O-β-D-xylopyranosyl l- (1 → 3) -O-α-L-rhamnopyranosyl- L-arabinofuranosyl-oleanolic acid -28-O-α-L-rhamnopyranosyl- (1 → 4) -β-D-glucopyranosyl- (1 → 6) -O- 3-O-β-D-glucopyranosyl- (1 → 4) -O-β-D-xylopyranosyl l- (1 → 3) -O-α-L-rhamnopyranosyl- (1 → 2) -O-α-L-arabinofuranosyl-oleanolic acid -28-O-α-L-rhamnopyranosyl - (1 → 4) -β-D-glucopyranosyl- (1 → 6) -O-6-O-acetyl-β-D-glucopyranoside (10). Conclusion Compounds 1, 4, 5, 7, 9 and 10 were isolated from this plant for the first time.
