[Study on chemical constituents of root bark of Discocleidion rufescens].

OBJECTIVE: To study the chemical constituents from root bark of Discocleidion rufescens. METHODS: Column chromatography and spectral analysis were used to isolate and identify the constituents. RESULTS: Ten compounds were obtained and identified from root bark of Discocleidion rufescens including beta-sitosterol (I), scopoletin (II), daucosterol (III), ricinine (IV), chrysophanol (V), aphyscion (VI), taraxerol (VII), pigenin (VIII), luteolin (IX), gallic acid (X). CONCLUSION: Ten compounds are isolated for the first time from root bark of Discocleidion rufescens. The monomer of Compounds II is isolated from this genus for the first time.
