[Chemical Constituents from Glycosmis pentaphylla]

Area of Science:

• Phytochemistry
• Natural Product Chemistry

Background:

• Glycosmis pentaphylla is a plant species with potential medicinal properties.
• Investigating its chemical constituents is crucial for understanding its bioactivity.

Purpose of the Study:

• To identify and characterize the chemical compounds present in Glycosmis pentaphylla.
• To report novel compounds isolated from this plant.

Main Methods:

• Extraction of Glycosmis pentaphylla using 95% ethanol.
• Fractionation and separation using silica gel and Sephadex LH-20 chromatography.
• Structure elucidation via spectral data analysis.

Main Results:

• Eleven compounds were isolated and identified.
• Identified compounds include dihydroflavonols (e.g., aromadendrin, dihydroquercetin isomers) and flavonoids (e.g., kaempferol, quercetin).
• Specific glycosides such as quercetin-3-O-α-L-arabinofuranoside and complex flavonoid glycosides were also identified.

Conclusions:

• All eleven isolated compounds are reported from Glycosmis pentaphylla for the first time.
• This study expands the knowledge of the phytochemical profile of Glycosmis pentaphylla.
