Bucharioside and buchariol from Salvia bucharica

Area of Science:

• Natural Product Chemistry
• Phytochemistry
• Organic Chemistry

Background:

• Salvia bucharica is a plant species with potential medicinal properties.
• Phytochemical investigations aim to identify bioactive compounds from medicinal plants.
• Isolation and structural elucidation of novel natural products contribute to understanding plant chemical diversity.

Purpose of the Study:

• To isolate and characterize new chemical constituents from Salvia bucharica.
• To elucidate the structures of novel compounds using spectroscopic methods.

Main Methods:

• Solvent extraction of Salvia bucharica plant material (methanol and hexane).
• Chromatographic separation techniques for isolating compounds.
• Nuclear Magnetic Resonance (NMR) spectroscopy (1D and 2D) for structure elucidation.

Main Results:

• Isolation of a new monoterpene-glycoside, bucharioside (2-exo-beta-D-glucopyranosyl-1,8-cineol).
• Isolation of a new sesquiterpenoid, buchariol (4,10-epoxy-6alpha-hydroxyguaiane).
• Confirmation of structures through comprehensive NMR spectroscopic analysis.

Conclusions:

• Two novel compounds, bucharioside and buchariol, have been identified from Salvia bucharica.
• The study expands the knowledge of the chemical constituents of the Salvia genus.
• NMR spectroscopy is a powerful tool for the structural determination of complex natural products.
