Summary
Researchers isolated a novel C-methyl flavonol glycoside from Pinus densiflora needles. This new compound, along with a known kaempferol derivative, expands our understanding of plant-derived flavonoids.
Area of Science:
- Phytochemistry
- Natural Product Chemistry
Background:
- Pinus densiflora (Japanese red pine) is a significant tree species with potential for novel bioactive compound discovery.
- Flavonoids are a diverse class of plant secondary metabolites known for their wide range of biological activities.
Purpose of the Study:
- To isolate and characterize novel compounds from the needles of Pinus densiflora.
- To identify known flavonoid derivatives present in the plant material.
Main Methods:
- Phytochemical investigation involving extraction and isolation techniques.
- Structure elucidation of isolated compounds using spectroscopic methods (e.g., NMR, Mass Spectrometry).
Main Results:
- A new C-methyl flavonol glycoside, 5,7,8,4'-tetrahydroxy-3-methoxy-6-methylflavone 8-O-beta-D-glucopyranoside, was successfully isolated and identified.
- Kaempferol 3-O-beta-(6"-acetyl)-galactopyranoside was also isolated from the same plant source.
Conclusions:
- The study successfully identified a new C-methyl flavonol glycoside from Pinus densiflora.
- This finding contributes to the phytochemical knowledge of Pinus species and the discovery of novel natural products.
