, p. 1541 - 1544 (1985)
Key Word Index - Gutierrezia grandis; Compositae; Astereae; ent-labdane derivatives; 3α-angeloyloxy-18-hydroxy-13-furyl-ent-labda-8(17)-ene; 3α-hydroxy-18-angeloyloxy-13-furyl-ent-labda-8(17)-ene; 3α,18-dihydroxy-13-furyl-ent-labda-8(17)-ene. - Two new diterpenes, 3α-angeloyloxy-18-hydroxy-13-furyl-ent-labda-8(17)-ene and 3α-hydroxy-18-angeloyloxy-13-furyl-ent-labda-8(17)-ene and an only recently reported third diterpene, 3α,18-dihydroxy-13-furyl-ent-labda-8(17)-ene, were isolated from the leaves of Gutierrezia grandis.Their structures were determined by mass spectral, IR, 1H NMR and 13C NMR data as well as chemical evidence.
