title: [Study on chemical constituents of Orobanche coerulescens].
abstract: Six compounds were isolated and purified from Orobanche coerulescens by extraction and different kinds of column chromatography. The structures were determined on the basis of spectral analysis. The structures were elucidated as D-mannitol(I), beta-sitosterol(II), succinic acid(III), caffeic acid(IV), protocatechuic aldehyde(V) and daucosterol(VI). All compounds are obtained from this plant for the first time.
