From the crude drug “sohakuhi”, the root barks of Morus plants, a novel isoprenoid flavone, moracenin C, having hypotensive activity has been isolated and the gross structure has been determined as represented by formula I (exclusive of stereochemistry). The absolute stereostructures of moracenin A, B and C have been deduced on the basis of physico-chemical evidence.
