Abstract
Nanoethosomal suspensions, composed of phospholipids, ethanol, and water, are novel lipid carriers. These suspensions have been reported to enhance the permeation of drugs into the skin as a result of the interdigitation effect of ethanol on the lipid bilayer of liposomes and by increasing the fluidity of lipids in the stratum corneum. The physical stability of the nanoethosomal suspension is still a critical research problem until now. This study investigated the commercial palm sucrose esters to improve the colloidal stability of nanoethosomal suspensions. The results indicated that palm sucrose esters (PSE) were effective for stabilizing nanoethosomal suspension of (-)-epigallocatechin gallate (EGCG) from green tea. A PSE concentration of 0.15% was optimal for a nanoethosomal suspension which gave mean diameter 75.5 ± 3.5 nm, zeta potential -30.8 ± 3.2 mV and polydispersity index 0.207 ± 0.017. Moreover, the effectiveness of stabilization was influenced by the degree of esterification of the sucrose esters: the sucrose polyesters could prolong the stability of nanoethosomes loaded with EGCG to a year, but the sucrose monoesters only provided less than 6 months of stabilization. EGCG nanoethosomal suspension stabilized by sucrose polyesters shows better inhibition effectiveness against UVB-induced skin damage than native EGCG. The nanoethosomal suspension has the potential for its utilization as skin care and other products. © 2016 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 105B: 2416-2425, 2017.

Abstract
This work assesses the current instrumentation, method development, and applications in countercurrent chromatography (CCC) and centrifugal partition chromatography (CPC), collectively referred to as countercurrent separation (CCS). The article provides a critical review of the CCS literature from 2007 since our last review (J. Nat. Prod. 2008, 71, 1489-1508), with a special emphasis on the applications of CCS in natural products research. The current state of CCS is reviewed in regard to three continuing topics (instrumentation, solvent system development, theory) and three new topics (optimization of parameters, workflow, bioactivity applications). The goals of this review are to deliver the necessary background with references for an up-to-date perspective of CCS, to point out its potential for the natural product scientist, and thereby to induce new applications in natural product chemistry, metabolome, and drug discovery research involving organisms from terrestrial and marine sources.

Simultaneous preparation of naturally abundant and rare catechins by tannase-mediated biotransformation combining high speed counter current chromatography. Food Chem 2013; 151:380-4.

Abstract
Simultaneous preparation of naturally rare catechins, EGC and EC, has been realized by tannase-mediated biotransformation combining high speed counter current chromatography. In addition, simultaneous preparation of the four catechins, EGCG, ECG, EGC, and EC in green tea extract has also been achieved by HSCCC under the normal phase and the reversed phase modes. The identity of the catechins was determined by HPLC-DAD-ESI-MS and quantification of the catechins was performed by HPLC-DAD. In a typical HSCCC separation, 27.2 mg 98.8% EGCG, 14.1 mg 94.7% EGC, and 9.3 mg 97.5% EC were obtained. This new method is efficient, time-saving and valuable for biological studies.

Abstract
Four flavonoids, isoastilbin, astilbin, isoengelitin, and engelitin were isolated and purified simultaneously from Smilacis Glabrae Roxb. for the first time by high performance counter-current chromatography using a system consisting of n-hexane-n-butanol-water (1:2:3, v/v/v). A total of 392.6 mg of astilbin, 71.4 mg of isoastilbin, 47.4 mg of engelitin, and 10.3 mg of isoengelitin were purified from 1.89 g of the ethyl acetate extract of Smilacis Glabrae Roxb. in six runs, each at over 94.51% purity as determined by HPLC. The structures of the four compounds were identified by their retention time, the LC-ESI-MS(n) in the negative ion mode, and confirmed by (1)H-NMR experiments. The characteristic LC-ESI-MS fragmentation patterns of the four compounds were discussed.
