Summary
Researchers discovered three new maltol glycosides from Flos Sophorae. Some compounds demonstrated protective effects against cell injury, suggesting potential therapeutic applications.
Area of Science:
- Phytochemistry
- Pharmacology
Background:
- Flos Sophorae is a traditional medicinal herb.
- Exploring its chemical constituents can reveal novel bioactive compounds.
Purpose of the Study:
- To isolate and characterize new compounds from Flos Sophorae.
- To evaluate the protective effects of isolated compounds against L6 cell injury.
Main Methods:
- Extraction of Flos Sophorae using 70% ethanol.
- Structure elucidation using chemical and spectroscopic techniques.
- Assessment of cytoprotective effects against antimycin A-induced injury in L6 cells.
Main Results:
- Three new maltol glycosides (soyamalosides A-C) were identified.
- Eight known compounds were also isolated, with compounds 4-6, 9, and 11 reported in the Sophora genus for the first time.
- Compounds 2, 3, and 10 exhibited significant protective effects against L6 cell injury.
Conclusions:
- The study expands the knowledge of Flos Sophorae's chemical diversity.
- Soyamalosides B, C, and compound 10 show potential as therapeutic agents for conditions involving cellular damage.
