Phenylpropanol derivatives from morina chinensis

Area of Science:

• Phytochemistry
• Natural Products Chemistry
• Organic Chemistry

Background:

• Morina chinensis is a traditional Chinese medicinal plant.
• Phenylpropanol derivatives are known for diverse biological activities.
• Investigating the chemical constituents of M. chinensis can lead to the discovery of novel compounds.

Purpose of the Study:

• To isolate and characterize novel phenylpropanol derivatives from Morina chinensis.
• To identify known compounds co-occurring in the plant extract.
• To contribute to the understanding of the phytochemical diversity of M. chinensis.

Main Methods:

• Extraction and isolation of compounds from Morina chinensis roots.
• Structure elucidation using comprehensive spectroscopic techniques, including 2D Nuclear Magnetic Resonance (2D NMR) and High-Resolution Mass Spectrometry (HRMS).

Main Results:

• Seven new phenylpropanol derivatives, designated morinins A-G (compounds 1-7), were successfully isolated.
• Five known phenylpropanol-related compounds were identified: 4-O-methylcinnamyl alcohol, 4-O-methylcinnamyl methyl ether, 4-O-methylcinnamyl acetate, p-methoxybenzaldehyde, and 4-O-methyl-(E)-coniferyl alcohol.
• The structures of all isolated compounds were rigorously determined through detailed analysis of spectral data.

Conclusions:

• The study successfully identified a series of new and known phenylpropanol derivatives from Morina chinensis.
• The findings expand the knowledge of the chemical constituents of this medicinal plant.
• The isolated compounds, particularly the novel morinins, may warrant further investigation for potential pharmacological activities.
