[Triterpenes from fruits of Paliurus ramosissimus].[Pubmed: 19806894]
To study the chemical constituents of the fruits of Paliurus ramosissimus, various chromatographic techniques were used to separate and purify the chemical constituents. Three triterpenes have been isolated and purified by using various column chromatography. Their structures were elucidated by their physico-chemical properties and spectroscopic data. These compounds were determined as: 22S, 23R-epoxy-tirucalla-7-ene-3alpha,24, 25-triol (1), 21S, 23R-epoxy-21, 24S, 25-trihydroxy-apotirucalla-7-ene-3-one (2), 21R, 23R-epoxy-21-ethoxy-24S, 25-dihydroxy-apotirucalla-7-ene-3-one (3), separately. Compound 1 is a new compound, and the others were obtained from this genus for the first time.

To study the chemical constituents from the fruits of Paliurus ramosissimus.
Calculating three-dimensional molecular structure of paliurine B from atom-atom distance and restrained energy minimization.[Pubmed: 8461326]
The conformation of paliurine B, a 13-membered cyclopeptide alkaloid isolated from Paliurus ramosissimus, has been determined from 2D NMR and distance geometry, followed by the restrained energy minimization calculation. The conformation of the 13-membered ring is well-defined but that of the acyclic dipeptide tail region is relatively disordered. In addition, the cavity in the 13-membered ring is just large enough to insert a magnesium ion but is a little small for calcium or sodium ions.
