Embodiment 1
[0009] Example 1: Separation, preparation and structure confirmation of SepulturinA
[0010] The preparation method of Sepulturin A is the same as that reported in the literature (Hydroxyclerodanes from Salviashannoni, J. Nat. Prod., 2013, 76, 1970-1975).
[0011] Confirmation of structure: colorless crystal, melting point 252-254°C, molecular formula C 20 h 22 o 7 , with an unsaturation of 10. H NMR spectrum data δ H (ppm, DMSO-d 6 , 500MHz): H-1(3.27, d, J=3.5), H-2(3.51, m), H-3(2.33, ddd, J=15.0, 5.0, 1.5), H-3(1.81, ddd , J=15.5, 12.5, 2.5), H-4 (2.59, dd, J=12.5, 5.0), H-6 (1.27, ddd, J=11.0, 3.0, 1.0), H-6 (1.59, m) , H-7 (2.06, m), H-7 (1.60, m), H-8 (2.57, m), H-11 (2.88, dd, J=16.0, 7.5), H-11 (2.04, m ), H-12 (5.61, dd, J=8.5, 1.5), H-14 (6.30, m), H-15 (7.37, t, J=1.5), H-16 (7.29, m), H- 19(4.10, d, J=8.5), H-19(4.16, dd, J=8.5, 2.0), H-20(1.19, s); C NMR data δ C (ppm, DMSO-d 6 , 150Hz): 56.0 (CH, 1-C), 58.7 (CH, 2-C), 19.6 (CH 2 , 3-C), 35.8(CH, 4-C),...
Embodiment 2
[0012] Embodiment 2: The pharmacological action test of SepulturinA
[0013] 1. Materials and Instruments
[0014] Neonatal 1-3 day old SD rat suckling mice (SPF grade), male or female, were provided by the Experimental Animal Center of Guangxi Medical University (production license for experimental animals: SCXK Gui 2009-0002). SepulturinA (purity ≥ 98%) is self-made. Fetal bovine serum was purchased from HyClone Company, DMEM medium was purchased from GIBCO Company, dimethyl sulfoxide (DMSO) and 0.25% trypsin (containing EDTA) were purchased from Solarbio Company, 5-bromodeoxyuridine (5-Brdu), Tetramethylazolium salt (MTT) was purchased from Sigma Company in the United States, the LDH test box was purchased from Nanjing Jiancheng Bioengineering Research Institute, the NOS kit (type) was purchased from Nanjing Jiancheng Bioengineering Research Institute, and the ATPase kit (Nanjing Jiancheng Bioengineering Research Institute) was purchased. Engineering Research Institute), ...
