Summary
A novel acetophenone glycoside, affinoside, was discovered in Exacum affine. Its structure was identified, along with three known glucosides, contributing to phytochemistry research.
Area of Science:
- Phytochemistry
- Natural Product Chemistry
Background:
- Exacum affine is a plant species with potential medicinal properties.
- Acetophenone glycosides are a class of natural compounds with diverse biological activities.
Purpose of the Study:
- To isolate and characterize new compounds from Exacum affine.
- To identify known compounds present in the plant.
Main Methods:
- Phytochemical analysis of aerial parts of Exacum affine.
- Structure elucidation using spectroscopic methods.
Main Results:
- A new acetophenone glycoside, named affinoside (2-O-primeverosylpaenol), was isolated.
- Three known glucosides: gentiopicroside, 2'-O-E/Z-p-coumaroylloganin, and glucopaeonol were identified.
Conclusions:
- The study expands the knowledge of the chemical constituents of Exacum affine.
- Affinoside represents a novel addition to the family of acetophenone glycosides.
