Summary
This study reports the first phytochemical investigation of Spatholobus sinensis caulis, identifying eight compounds including a new compound, spatholosineside A. These findings contribute to understanding the chemical constituents of this traditional medicinal plant.
Area of Science:
- Phytochemistry
- Natural Product Chemistry
- Ethnobotany
Context:
- Spatholobus sinensis (Leguminosae family) caulis is used regionally as 'ji-xue-teng'.
- No prior phytochemical investigations of S. sinensis have been documented.
- This study addresses the lack of chemical knowledge regarding S. sinensis.
Purpose:
- To conduct the first phytochemical investigation of Spatholobus sinensis caulis.
- To isolate and identify chemical constituents from the ethanol extract of S. sinensis caulis.
- To characterize a novel compound from this plant species.
Summary:
- Eight compounds were isolated from the ethanol extract of S. sinensis caulis using solvent extraction and column chromatography.
- The identified compounds include spatholosineside A (a new compound), 2",4",5,7-tetrahydroxyisoflavone, isoliquiritigenin, lupinalbin A, coumestrol, naringenin, protocatechuic acid, and leonuriside A.
- Structural elucidation was achieved through analysis of physic-chemical constants and spectral data.
Impact:
- Establishes a foundational phytochemical profile for Spatholobus sinensis.
- Identifies spatholosineside A as a novel chemical entity.
- Provides valuable data for further research into the medicinal properties and potential applications of S. sinensis.
