Description | Nigakihemiacetal E belongs to the class of organic compounds known as quassinoids. These are a group of compounds chemically degraded from triterpenes. According to their basic skeleton, quassinoids are categorized into five distinct groups, C-18, C-19, C-20, C-22 and C-25 types. The C-20 quassinoids can be further classified into two types, tetracyclic and the pentacyclic. The tetracyclic variety does not have oxygenation at C-20, while the pentacyclic quassinoids possess additional oxygenation at C-20 that allows for the formation of an additional ring. (1s,2s,6s,7s,9r,13r,14s,15r,17s)-11,14,15-trihydroxy-4-methoxy-2,6,14,17-tetramethyl-10-oxatetracyclo[7.7.1.0²,⁷.0¹³,¹⁷]heptadec-4-ene-3,16-dione is found in Picrasma quassioides. Based on a literature review very few articles have been published on Nigakihemiacetal E. |
