| titleOfInvention | Method for separation and purification of water-soluble catechol-type tetrahydroisoquinoline alkaloids |
| abstract | The present invention provides a method for separating and purifying water-soluble catechol-type tetrahydroisoquinoline alkaloids by utilizing macroporous resin, wherein the water-soluble catechol-type tetrahydroisoquinoline alkaloids have the formula (I). Show structure: Wherein, R is selected from C 1 -C 5 straight or branched chain alkyl, alicyclic alkyl containing at least one heteroatom, alicyclic alkyl substituted by at least one substituted group, phenyl, benzyl, Phenyl substituted with at least one substituent group and benzyl substituted with at least one substituent group; the heteroatom is selected from N, O and S; the substituent group is selected from substituted or unsubstituted C 1 -C 5 Linear or branched alkyl, C 1 -C 5 branched or branched alkoxy, nitro, halogen and hydroxyl. The method is simple, economical, efficient and environmentally friendly. |
