Two new ent-labdane diterpenoid glycosides from the aerial parts of Andrographis paniculata.
Two new ent-labdane diterpenoid glycosides were isolated from the aerial parts of Andrographis paniculata. Their structures were elucidated as 3-O-beta-D-glucosyl-14-deoxyandrographiside (1) and 3-O-beta-D-glucosyl-14-deoxy-11,12-didehydroandrographiside (2) by means of 1D and 2D NMR spectral and chemical methods.
