Source of material
The dried and powdered leaves of Isodon rubescence (Hemsl. Hara.) were extracted with methanol four times at room temperature. The residue was dissolved in methanol and ethyl acetate, which was then divided into five fractions using silica gel column with petroleum ether/ethyl acetate (volume ratio 100:1-1:1). Fraction B was separated by silica gel column with petroleum ether/ethyl acetate (volume ratio 9:1) to get the crude product. Then the product was purified by sephadex LH-20 with dichloromethane/methanol (volume ratio 1:1). After dissolving the sample with methanol colorless needle crystals of the title compound (20 mg, guidongnin B) were obtained within 1 day.
Experimental details
The suitable crystal was selected and measured on a ’Bruker APEX-II CCD’ diffractometer with MoKα monochromated radiation (λ = 0.71073 Å) at 302(2) K. Using Olex2 [1], the structure was solved with the ShelXL [2] structure solution program and refined with the ShelXL [3] refinement package. All hydrogen atoms were positioned geometrically, with the d(C—H) = 0.96–0.98 Å, Uiso(H) = 1.2 times Ueq(C) and Uiso(H) = 1.5 times Ueq(O).
Comment
Terpenoids are abundant in the genus of Isodon, and possess a wide range of bioactivities [4], [5]. In order to discover active terpenoids from Isodon rubescence (Hemsl. Hara.), phytochemical investigation led to the isolation of the title compound. The bond distances and bond angles in the title structure are all in normal ranges. The crystal structure of title compound contains one five-membered lactone ring, one six-membered lactone ring, one five-membered carbon ring and two six-membered carbon rings. The carbon skeleton is substituted by three carbonyl groups and two methyl groups. The lactone rings were further determined by the distances d(C18—O1) = 1.197(3) Å, d(C18—O2) = 1.347(3) Å, d(C6—O2) = 1.437(3) Å and the distances d(C7—O3) = 1.340(3) Å, d (C7—O4) = 1.196(3) Å, d (C20—O3) = 1.445(3) Å. The carbonyl group was confirmed by the distance of d(C15—O5) = 1.205(3) Å.
