A new flavone, wightianin (1), along with five known compounds, n-triacontanol (2), betulinic acid (3), oleanolic acid (4), 3,4-O-isopropylidene-shikimic acid (5), and isoquercitrin (6), were isolated from the whole plants of Hypericum wightianum Wall ex Wight et Arn. Their structures were elucidated on the basis of spectral data, including 2D NMR techniques.
