[Chemical Constituents from Cremastra appendiculata]
Researchers identified ten chemical compounds from the tuber extract of Cremastra appendiculata. Five of these compounds, including shancigusin I, were isolated for the first time from this plant species.
Area of Science:
- Phytochemistry
- Natural Product Chemistry
- Medicinal Botany
Background:
- Cremastra appendiculata is an orchid species with potential medicinal properties.
- Understanding its chemical composition is crucial for exploring its therapeutic applications.
Purpose of the Study:
- To isolate and identify the chemical constituents present in the tuber extract of Cremastra appendiculata.
Main Methods:
- Compounds were isolated using column chromatography (silica gel, Sephadex LH-20) and ODS-HPLC.
- Structural elucidation was performed using spectroscopic techniques, including 1H-NMR and 13C-NMR.
Main Results:
- Ten compounds were successfully isolated from the ethyl acetate extract of Cremastra appendiculata tubers.
- These compounds include shancigusin I, 4-O-β-D-glucopyranosyl cinnamate, bulbocodin D, blestriarene A, 7-hydroxy-2,4-dimethoxy phenanthrene, coelonin, militarine, gastrodine, 3-hydroxyphenylpropionic acid, and cinnamic acid.
Conclusions:
- Five compounds (shancigusin I, 4-O-β-D-glucopyranosyl cinnamate, bulbocodin D, 3-hydroxyphenylpropionic acid, and cinnamic acid) represent novel findings for Cremastra appendiculata.
- This study expands the known phytochemical profile of Cremastra appendiculata.
