Novel chromones from Spathelia sorbifolia

Area of Science:

• Phytochemistry
• Natural Products Chemistry
• Pharmacology

Background:

• Spathelia sorbifolia is a plant species known for its diverse chemical constituents.
• Chromones are a class of organic compounds with various biological activities.
• Investigating the phytochemical profile of S. sorbifolia can lead to the discovery of novel bioactive molecules.

Purpose of the Study:

• To isolate and characterize new chromone compounds from Spathelia sorbifolia.
• To evaluate the cytotoxic potential of isolated compounds against 9PS cells.

Main Methods:

• Extraction of plant material (twigs and leaves) using 10% aqueous methanol.
• Isolation and purification of chromone compounds using chromatographic techniques.
• Cytotoxicity assays to assess the biological activity of the isolated compounds.

Main Results:

• Three new chromones were identified: 10-(2',3'-dihydroxy-3'-methylbutanyl)-spatheliachromen, 10-(1',2',3'-trihydroxy-3'-methylbutanyl)spatheliachromen, and 6-(3'-hydroxy-3'-methyl-trans-but-1'-enyl)-O-methylisospatheliachrome n.
• Five known chromones were also isolated.
• Compound 2 (spatheliabischromen) and 5-O-methylsorbifolin exhibited cytotoxicity against 9PS cells.

Conclusions:

• The phytochemical investigation of Spathelia sorbifolia yielded novel chromone structures.
• Certain isolated chromones, particularly spatheliabischromen, possess significant cytotoxic activity, warranting further research for potential anticancer drug development.
