Journal of Shenyang Pharmaceutical University,2013,30(9):669-73. | Isolation and identification of diterpenoids from Suregada glomerulata (Bl.) Baill[Reference: WebLink] | To isolate and identify the chemical constituents from Suregadaglomerulata(Bl.)Baill. METHODS AND RESULTS: The compounds were isolated by chromatography of silica gel,Sephadex LH20,ODS column and semi-preparative C18 HPLC,their structures were identified on the basis of physicochemical data and spectroscopic analysis. Twelve compounds were isolated and their structures were identified as 3α,17-dihydroxy-ent-pimara-8(14),15-diene(1),3β-acetoxy-1-one-8β,14α-epoxy-13,15-abiatene-16,12-olide(2),gelomulide D(3),gelomulide E(4),helioscopinolide C(5),3β-acetoxy-8β,14α-dihydroxy-1-one-13,15-abiatene-16,12-olide(6),3β,6β-diacetoxy-1-one8β,14α-epoxy-13,15-abiatene-16,12-olide(7),Gelomulide A(8),gelomulide G(9),helioscopinolide A(10),helioscopinolide D(11)and helioscopinolide B(12). CONCLUSIONS: Compound 1 is reported fromSuregada genus for the first time and compounds 2-8 are isolated from this plant for the first time. |
