Crude cottonseed oil contains in addition to the constituents previously reported a lecithin type of phosphatide which gives an ether-soluble compound with cadmium chloride. This phosphatide can only be partially removed from the oil by extraction with alcohol. It has been found in the "settlings...
The resin is partially removed from an alcoholic solution by an alcoholic solution of copper acetate in the form of a dark yellow flocculent precipitate. The copper salt is insoluble in alcohol and ether. It is believed that part of the deep red color of the crude oil is due to this ...
The chemical components of the essential oil from the fruits of Forsythia suspensa(Thunb.)Vahl,which is widely used in traditional Chinese medicine for the treatment of sore throat and febrile disease.were analyzed by capillary gas chromatography. Nineteen constituents have been identified bv GLC and...
In the twelve years since the first review article dealing with chemical constituents of the Hepaticae appeared in this series as Volume 42 (19), several short reviews concerned with chemical constituents of bryophytes have been published (22, 96, 144, 2
