(A) Structures of jatrophane diterpenes identified in the chloroform extract of leafy spurge (Euphorbia esula L.) root material. Compound 1 = esulone A and compound 2 = kansuinine B. Kansuinine B (2) was also present in the chloroform extract of leafy spurge root exudates. (B) Structures of ellagic acid and its derivatives identified in the chloroform extract of leafy spurge (Euphorbia esula L.) root material. Compound 3 = 3,3′,4-tri-O-methylellagic acid, 4 = ellagic acid, 5 = 4-O-[b-D-xylopyranosyl]-3,3′-di-O-methylellagic acid, and 6 = 3,3′di-O-methylellagic acid. 3,3′,4-tri-O-methylellagic acid (3) was also present in the chloroform extract of leafy spurge root exudates. The xylopyranosyl ellagic acid derivative (5) and 3,3′di-O-methylellagic acid (6) were also present in the ethyl acetate extract of leafy spurge root exudates.
