Monechmol, a New Pentacyclic Triterpene from Monechma debile

Area of Science:

• Phytochemistry
• Natural Product Chemistry

Background:

• MONECHMA DEBILE Hochst is a plant species with potential medicinal properties.
• Triterpenes are a class of naturally occurring compounds with diverse biological activities.

Purpose of the Study:

• To isolate and characterize new chemical compounds from MONECHMA DEBILE Hochst.
• To identify the structure of a novel triterpene glucoside.

Main Methods:

• Phytochemical investigation of the butanol fraction of MONECHMA DEBILE Hochst.
• Isolation and purification of the target compound.
• Spectroscopic characterization (e.g., NMR, MS) for structural elucidation.

Main Results:

• Isolation of a new hydroxypenta-cyclic triterpene, named monechmol.
• Characterization of the isolated glucoside as monechmol 3-O-beta-glucoside.
• Confirmation of the beta-glycosidic linkage at the 3-O position.

Conclusions:

• Monechmol is a novel triterpene isolated from MONECHMA DEBILE Hochst.
• The glucoside derivative, monechmol 3-O-beta-glucoside, has been fully characterized.
• This discovery expands the known chemical constituents of MONECHMA DEBILE Hochst.
