Four flavonol glycosides from Achlys triphylla

Area of Science:

• Phytochemistry
• Natural Product Chemistry

Background:

• Achlys triphylla is a plant species with potential medicinal properties.
• Flavonol glycosides are a class of natural compounds known for their biological activities.

Purpose of the Study:

• To isolate and characterize novel compounds from Achlys triphylla.
• To expand the understanding of the chemical constituents of Achlys triphylla.

Main Methods:

• Spectroscopic analysis (e.g., NMR, Mass Spectrometry) was employed for structural elucidation.
• Isolation of compounds was performed using chromatographic techniques.

Main Results:

• Four new flavonol glycosides were identified: isorhamnetin 3-glucosyl(1----3)galactoside, isorhamnetin 3-[6''acetylglucosyl(1----3)galactoside], isorhamnetin 3-[4''6''-di-acetylglucosyl(1----3)galactoside], and syringetin 3-[6''-acetylglucosyl(1----3)galactoside].
• Eight known compounds were also isolated from the underground parts.
• Seven known compounds were confirmed in the aerial parts of the plant.

Conclusions:

• The study successfully identified new flavonol glycosides from Achlys triphylla.
• This research contributes to the phytochemical knowledge of the Achlys genus.
