Barks of mulberry used for drugs is believed to be derived from Morus acidosa Griff. Alcoholic extract of the bark was concentrated and the precipitate that separated out on cooling was saponified with alcoholic potash and α- and β-amyrin and stearic acid were obtained. Isolation of β-amyrin from mulberry bark is worthy of notice.
