From the alcohol extract of the whole plant of Humata pectinata, two new triterpenoids were isolated alone with the known compounds neohop-13(18)-ene(4),neohop-12-ene (5), hop-21-ene (6), hop-22(29)-ene (7), and diplopterol(8). On the basis of spectral and chemical evidences,it was show that the two new triterpenes have the structures corresponding to hopao-3β-o1 (1) and hopan-3β-yl acetate (2).
