The chinese drugs of the umbelliferae 2. chemical constituents of the roots of heracleum nepalense



The chinese drugs of the umbelliferae 2. chemical constituents of the roots of heracleum nepalense



Acta Botanica Yunnanica 2(2): 224-227



The dried roots of H. nepalense D. Don. were extracted with ether, and the extract chromatographed over alumina. Four furanocoumarins were identified: pimpinellin, bergapten, sphondin and isopimpinellin by melting point, IR and NMR spectra. .beta.-Sitosterol was also isolated.
