title: [Chemical constituents from whole plants of Valeriana hardwickii].
abstract: Chemical investigation of the whole plants of Valeriana hardwickii has led to the isolation of 11 flavones and 2 monoterpe- noids by using various chromatographic techniques including column chromatography on silica gel and Sephadex LH-20, preparative TLC, and preparative HPLC. Their structures were identified by spectroscopic data analysis as syzalterin (1), 6-methylapigenin (2), 5-hydroxy-7,4'-dimethoxyflavone (3), genkwanin (4), acacetin (5), apigenin (6), quercetin (7), tricin (8), (-)-farrerol (9), sosakuranetin (10), 5,3',4'-trihydroxy-7-methoxyflavanone (11), (-)-bornyl ferulate ( 12) , and (-)-bornyl caffeate ( 13). All compounds were isolated from this plant for the first time, while compounds 1, 9-13 were obtained from this genus for the first time.
