Common Name

(1r,18r,21s)-9,12,13,14-tetramethoxy-21-methyl-5,7,20-trioxapentacyclo[16.2.1.0²,¹⁰.0⁴,⁸.0¹¹,¹⁶]henicosa-2(10),3,8,11(16),12,14-hexaene

Description

(1R,18R,21S)-9,12,13,14-tetramethoxy-21-methyl-5,7,20-trioxapentacyclo[16.2.1.0²,¹⁰.0⁴,⁸.0¹¹,¹⁶]Henicosa-2,4(8),9,11,13,15-hexaene belongs to the class of organic compounds known as hydrolyzable tannins. These are tannins with a structure characterized by either of the following models. In model 1, the structure contains galloyl units (in some cases, shikimic acid units) that are linked to diverse polyol carbohydrate-, catechin-, or triterpenoid units. In model 2, contains at least two galloyl units C-C coupled to each other, and do not contain a glycosidically linked catechin unit. (1r,18r,21s)-9,12,13,14-tetramethoxy-21-methyl-5,7,20-trioxapentacyclo[16.2.1.0²,¹⁰.0⁴,⁸.0¹¹,¹⁶]henicosa-2(10),3,8,11(16),12,14-hexaene is found in Magnolia fraseri. Based on a literature review very few articles have been published on (1R,18R,21S)-9,12,13,14-tetramethoxy-21-methyl-5,7,20-trioxapentacyclo[16.2.1.0²,¹⁰.0⁴,⁸.0¹¹,¹⁶]Henicosa-2,4(8),9,11,13,15-hexaene.

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as hydrolyzable tannins. These are tannins with a structure characterized by either of the following models. In model 1, the structure contains galloyl units (in some cases, shikimic acid units) that are linked to diverse polyol carbohydrate-, catechin-, or triterpenoid units. In model 2, contains at least two galloyl units C-C coupled to each other, and do not contain a glycosidically linked catechin unit.
