Objective: To study the chemical constituents of Reineckea carnea.
Methods: The compounds were isolated by extraction, silica gel and reversed phase silica gel column chromatography. The structures were identified by various spectroscopic methods including 1D and 2D-NMR spectrum, MS, IR, etc.
Results: Six compounds were isolated and identified as beta-sitosterol (1), isorhodeasapogenin (2), isorhodeasapogenin (3), (25S)-1beta,3beta,4beta-trihydroxyspirotan-5beta-yl-O-beta-D-glucopyranoside (4), kitigenin-5-O-beta-D-glucopyranoside (5) and nicotianoside B (6).
Conclusion: Compounds 4, 6 are obtained from this plant for the first time.
