Area of Science:

Phytochemistry
Natural Product Chemistry
Organic Chemistry

Context:

Solanum torvum, a widely used medicinal plant, has not been fully characterized for its chemical constituents.
Understanding the phytochemical profile of S. torvum is crucial for its ethnobotanical and pharmacological applications.

Purpose:

To isolate and elucidate the chemical structures of compounds present in the aerial parts of Solanum torvum.
To identify novel or previously unreported chemical constituents from this plant species.

Summary:

Six triterpenes were successfully isolated from the 95% alcohol extract of S. torvum aerial parts.
The identified triterpenes include 3beta-acetyloleanolic acid, 3-O-acetyl-11alpha, 12alpha-epoxy-oleanan-28, 13beta-olide, oleanolic acid, ursolic acid, 2alpha-hydroxy-oleanolic acid, and 2alpha, 3beta-dihydroxyursolic acid.
Structural determination was achieved using Nuclear Magnetic Resonance (NMR) and Mass Spectrometry (MS) techniques.

Impact:

This research reports the first isolation of these six triterpenes from Solanum torvum.
The findings contribute to the phytochemical knowledge of S. torvum, potentially aiding in the discovery of new bioactive compounds.
