A Strategy for Preparative Separation of 10 Lignans from Justicia procumbens L. by High-Speed Counter-Current Chromatography.
Jiang J, Dong H, Wang T, Zhao R, Mu Y, Geng Y, Zheng Z, Wang X. Jiang J, et al. Molecules. 2017 Nov 23;22(12):2024. doi: 10.3390/molecules22122024. Molecules. 2017. PMID: 29168751 Free PMC article.
The enriched mixture (91.3 mg) was further separated using the solvent system consisting of petroleum-ethyl acetate-methanol-H2O (3:3.8:3:3.8, v/v), yielding 12.1 mg of procumbenoside E (a); 7.6 mg of diphyllin-1-O-beta-d-apiofuranoside (b); 7.4 mg of diphyllin (c); 8.3 mg of 6'- …

Prieto JM, Recio MC, Giner RM, Máñez S, Massmanian A, Waterman PG, Ríos JL. Prieto JM, et al. Z Naturforsch C J Biosci. 1996 Sep-Oct;51(9-10):618-22. doi: 10.1515/znc-1996-9-1002. Z Naturforsch C J Biosci. 1996. PMID: 8921631 Free article.
They were identified by spectroscopic methods, including 13C NMR and heteronuclear multiple bond correlation (HMBC), as diphyllin acetyl apioside and tuberculation. The former was the most active on acute TPA edema with a ID50 of 0.27 mumol/ear....
