Application of mixed cloud point extraction for the analysis of six flavonoids in Apocynum venetum leaf samples by high performance liquid chromatography.[Pubmed: 25625477]

METHODS AND RESULTS:
A simple, inexpensive and efficient method based on the mixed cloud point extraction (MCPE) combined with high performance liquid chromatography was developed for the simultaneous separation and determination of six flavonoids (rutin, hyperoside, Quercetin-3-O-sophoroside, isoquercitrin, astragalin and quercetin) in Apocynum venetum leaf samples. The non-ionic surfactant Genapol X-080 and cetyl-trimethyl ammonium bromide (CTAB) was chosen as the mixed extracting solvent. Parameters that affect the MCPE processes, such as the content of Genapol X-080 and CTAB, pH, salt content, extraction temperature and time were investigated and optimized. Under the optimized conditions, the calibration curve for six flavonoids were all linear with the correlation coefficients greater than 0.9994. The intra-day and inter-day precision (RSD) were below 8.1% and the limits of detection (LOD) for the six flavonoids were 1.2-5.0 ng mL(-1) (S/N=3).
CONCLUSIONS:
The proposed method was successfully used to separate and determine the six flavonoids in A. venetum leaf samples.

New flavonol glycosides from the leaves of Triantha japonica and Tofieldia nuda.[Pubmed:24273859]

Nat Prod Commun. 2013 Sep;8(9):1251-4.

Two new flavonol glycosides were isolated from the leaves of Triantha japonica, together with eight known flavonols, kaempferol 3-O-sophoroside, kaempferol 3-O-sambubioside, kaempferol 3-O-glucosyl-(1 --> 2)-[glucosyl-(1 --> 6)-glucoside], quercetin 3-O-sophoroside, quercetin 3-O-sambubioside, isorhamnetin 3-O-glucoside, isorhamnetin 3-O-sophoroside and isorhamnetin 3-O-sambubioside. The new compounds were identified as kaempferol 3-O-beta-xylopyranosyl-(1 --> 2)-[beta-glucopyranosyl-(1 --> 6)-beta-glucopyranoside] (1) and isorhamnetin 3-O-beta-xylopyranosyl-(1 --> 2)-[beta-glucopyranosyl-(1 --> 6)-beta-glucopyranoside] (3) by UV, LC-MS, acid hydrolysis, and 1H and 13C NMR spectroscopy. Another two new flavonol glycosides were isolated from theleaves of Tofieldia nuda, and identified as kaempferol 3-O-beta-glucopyranosyl-(1 --> 2)-[beta-glucopyranosyl-(1 --> 6)-beta-galactopyranoside] (4) and quercetin 3-O-beta-glucopyranosyl-(1 --> 2)-[beta-glucopyranosyl-(1 --> 6)-beta-galactopyranoside] (5). Though the genera Triantha and Tofieldia were treated as Tofieldia sensu lato, they were recently divided into two genera. It was shown by this survey that their flavonoid composition were also different to each other.
