Protocol
Structure Identification:
Yao Xue Xue Bao. 1993;28(6):432-6.
Isolation and structure elucidation of qianhucoumarin A.[Pubmed: 8249601]
Seven compounds were isolated from the traditional Chinese Medicine Qianhu, roots of Peucedanum praeruptorum Dunn.
METHODS AND RESULTS:
Their structures were identified as psoralen (II), 5-methoxypsoralen (III), 8-methoxypsoralen (IV), pteryxin (V), peucedanocoumarin II (VI), beta-sitosterol (VII) and Qianhucoumarin A (VIII) by physico-chemical constants and spectral analyses (UV, IR, 1HNMR, 13CNMR, EIMS). Qianhucoumarin A is a new compound with the structure of 3'(R)-hydroxy-4'(R)-tigloyloxy-3',4'-dihydroseslin. Its absolute configurations were determined by chemical correlation with known compounds.
CONCLUSIONS:
II, III, IV and Qianhucoumarin A were first isolated from this plant.
