Two New Steroidal Glucuronides from Solanum lyratum, II1

Area of Science:

• Phytochemistry
• Natural Products Chemistry
• Organic Chemistry

Background:

• Solanum lyratum is a plant species with a history of traditional medicinal use.
• The chemical constituents of Solanum lyratum are not fully elucidated.
• Steroidal compounds are known for diverse biological activities.

Purpose of the Study:

• To isolate and characterize novel steroidal compounds from Solanum lyratum.
• To contribute to the phytochemical database of Solanum species.
• To identify potential bioactive natural products.

Main Methods:

• Extraction of compounds from the aerial parts of Solanum lyratum.
• Chromatographic techniques for isolation (e.g., column chromatography).
• Spectroscopic methods (e.g., NMR, Mass Spectrometry) for structure elucidation.

Main Results:

• Isolation of two new steroidal glucuronides: a furostanol derivative and a spirostanol derivative.
• Identification of two known glycosides: SL-a and tigogenin 3-O-beta-D-glucopyranoside.
• Confirmation of the chemical structures of the isolated compounds.

Conclusions:

• The aerial parts of Solanum lyratum are a source of unique steroidal glucuronides.
• The findings expand the knowledge of steroidal glycosides in the Solanum genus.
• Further investigation into the biological activities of these compounds is warranted.
