摘要：

Two new neo-clerodane diterpenoids, scutegalin C and D, have been isolated from the acetone extract of the aerial parts of Scutellaria galericulata. The structures of the new compounds were established by chemical and spectroscopic means as (13S, 19R)-6 alpha-acetoxy-4 alpha,18-epoxy-7 beta-tigloyloxy-neo-cleroda-(19-O-tigloyl)-19,2 alpha, 16,15-dihemiacetal (scutegalin C) and (13S,19R)-6 alpha-acetoxy-4 alpha,18-epoxy-neo-cleroda-(19-O-tigloyl)-19,2 alpha, 16,15-dihemiacetal (scutegalin D). The absolute stereochemistry of scutegallin C was determined by chemical correlation with the already known neo-clerodane scutegalin B.
