METHODS: Many kinds of column chromatography were used to isolate the constituents from the extracts of the buds of L. macrarahoides. The chemical constituents of the plant were elucidated by means of spectroscopic methods, respectively. RESULTS: Eleven compounds were obtained and identified as hederagenin-28-O-[β-D-glucopyranosyl-( 1→6)-β- D-glucopyranosyll ester ( Ⅰ ), 3-O-[ α- L-rhamnopyranosyl- ( 1 → 2 )-α- L-ambinopyranosyl ] hederagenin (Ⅱ ), 3-O- [ β- D-glucopyranosyl-( 1→ 3 )-α- L-rhamnopyranosyl- ( 1→ 2 )-α- L-arabinopyranosyl ] hederagenin ( Ⅲ ), 3- O-α- L-arabinopyranosyl hederagenin-28-O-[β-D- glucopyranosyl-( 1→ 6)-β-D-glucopyranosyl ] ester ( Ⅳ ), 3-O-[ β-D-glucopyranosyl-( 1→ 4)-β-D- glucopyranosyl- (1→3) -α- L-rhamnopyranosyl- ( 1→2)-α- L-arabinopyranosyl ] hederagenin ( Ⅴ ), 3- O- [ α- L-rhamnopyranosyl- ( 1→ 2)-α- L-arabinopyranosyl ] hederagenin-28- O- [β- D-glucopyranosyl- ( 1 → 6 ) -β- D-glucopyranosyl ] ester ( Ⅵ ), 3- O- [β- D- glucopyranosyl- ( 1→ 3)-α- L-rhamnopyranosyl- ( 1→ 2 ) -α- L-arabinopyranosyl ] hederagenin-28- O- [ β- D-glucopyranosyl- ( 1 → 6 )-β- D-glucopyranosyl ] ester ( Ⅶ ), 3- O-[β- D-glucopyranosyl- (1→4)-β- D-glucopyranosyl- ( 1→3)-α- L-rhamnowranosyl- ( 1→2)-α- L-arabinopyranosyl ] hederagenin- 28- O- [ β- D-glucopyranosyl- (1→6) -β- D-glucopyranosyll ester( Ⅷ), kaempferol-3- O-β- D-glueopyranoside ( Ⅸ ), turin( Ⅹ ), luteolin-7- O-β-D-glucopyranoside( Ⅺ ). CONCLUSION: Saponins Ⅰ- V, flavonoids Ⅸ and Ⅹ were isolated from the plant for the first time.
