CHAMY, MARÍA CRISTINA; PIOVANO, MARISA; GARBARINO, JUAN A.  and  MENDOZA, JAMILET. DITERPENOIDS FROM CALCEOLARIA GLABRATA. Bol. Soc. Chil. Quím. [online]. 2001, vol.46, n.2, pp.223-225. ISSN 0366-1644.  http://dx.doi.org/10.4067/S0366-16442001000200018.

From the aerial parts of Calceolaria glabrata, a new diterpene ,13-methylene-7-acetoxy-stemarane (1), together with 13-isovaleroyl-7-acetoxy-thyrsiflorane (2) and 13-isovaleroyl-7-malonyloxy-thyrsiflorane (3) were isolated. Their structures were elucidated by spectroscopic means

Keywords : Calceolaria; Scrophulariaceae; diterpenes; stemaranes; thyrsifloranes.
