Objective:
To study the chemical constituents from Caragana intermedia.
Methods:
The compounds were separated by chromatography methods. Their structures were identified by spectral analysis.
Results:
Eight compounds were isolated and identified as 7,5'-dihydroxy-3 '-methoxyisoflavone-7-O-beta-D-glucoside (1), isorhamnetin 7-O-alpha-L-rhamnoside (2), 3, 4-dihydroxybenzoic acid (3), N-trans-caffeoyltyramine (4), D-3-O-methyl-inositol (5),7alpha-hydroxy-beta-sitosterol (6),7beta-hydroxy-beta-sitosterol (7) and stearic acid (8).
Conclusion:
All these compounds were obtained from this plant for the first time.
