Embodiment 1
[0010] Example 1: Isolation, Preparation and Structure Confirmation of Cephaloziellin F
[0011] The preparation method of Cephaloziellin F is the same as that reported in the literature (Secondary Metabolites from the Chinese Liverwort Cephaloziellakiaeri, J. Nat. Prod., 2013, 76, 1700-1708).
[0012] Confirmation of structure: colorless oil (methanol). According to HR-ESI-MS, the molecular formula is C 21 h 26 o 6 , with an unsaturation of 9. H NMR spectrum data δ H (ppm, DMSO-d 6 , 600MHz): H-1(1.49, m), H-1(1.91, m), H-2(2.32, m), H-2(2.11, m), H-3(6.83, br, s) , H-6 (1.79, m), H-6 (2.13, m), H-7 (2.83, m), H-7 (2.22, m), H-9 (2.95, t, J=9.6), H-10 (1.53, m), H-11 (2.35, m, 2H), H-12 (5.40, br, d, J=6.6), H-14 (6.29, br, s), H-15 ( 7.35, br, s), H-16 (7.37, br, s), H-17 (2.04, s), H-19 (1.11, s), 18-OMe (3.70, s); carbon NMR data δ C (ppm, DMSO-d 6 , 150Hz): 20.8 (CH 2 , 1-C), 25.7 (CH 2 , 2-C), 139.1 (CH, 3-C), 136.2 (C, 4-C), 39.0 (C, 5-C), 29.4 (CH 2 , 6-C...
