The present study established a determination method of Psoraleae Fructus by quantitative analysis of multi-components by the single marker(QAMS) and further improved the thin-layer chromatography(TLC) method. The QAMS method was established by UPLC with psoralen as the internal marker, and the content of psoralenoside, isopsoralenoside, psoralen, and isopsoralen was simultaneously determined. As revealed by the comparison with results of the external standard method, the QAMS method was accurate and feasible. According to the current quality standards of Psoraleae Fructus, the TLC method was further optimized and improved, and bakuchiol was added for identification based on the original TLC method with psoralen and isopsoralen as indicators. This study provides a reference for improving the quality control method of Psoraleae Fructus.

A UPLC method has been developed for simultaneous determination of nine furanocoumarins of Angelica dahurics,and was used for quality evaluation of A. dahurica from different habitats. ACQUITY UPLC BEH C18 chromatographic column was employed,the separation was performed with the mobile phase consisting of acetonitrile and water,and the detection wavelength was set at254 nm. This method was used to simultaneously determine the content of xanthotoxol,oxypeucedaninhydrate,byak-angelicin,psoralen,xanthotoxin,bergapten,oxypeucedanin,imperatorin and isoimperatorin in A. dahurica from different habitats. Then,the further quality assessment of the drug was carried out by similarity evaluation,cluster analysis( CA),principal component analysis( PCA),and orthogonal partial least squares discriminant analysis( OPLS-DA). The content order of measured furanocoumarins from high to low was: oxypeucedanin>imperatorin>isoimperatorin>oxypeucedaninhydrate>bergapten>byak-angelicin>xanthotoxin>xanthotoxol>psoralen,with the mean content 2. 844,1. 277,0. 649 2,0. 216 2,0. 129 8,0. 062 68,0. 052 68,0. 019 30,0. 018 19 mg·g-1,respectively. There were difference between the batches of the drug,and the quality was influenced by smouldering sulphur based on the results of chemical pattern recognition and content determination. Finally,six active ingredients were recognized as the quality makers using OPLS-DA method. The validated UPLC fingerprint combined with chemical pattern recognition method can be used in the quality control and evaluation of A. dahurica.

A HPLC method has been developed in the current investigation for simultaneous determination of three chemical markers of by akangelicin, imperatorin and isoimperatorin in Radix Angelicae Dahuricae. Separation was performed at 30 degrees C. on achromatographic column of Platisil ODS C18 (4.6 mm x 250 mm, 5 μm). The mobile phase was acetonitrile-water. The flow rate was 1.0 mL x min(-1) and the detection wavelength was 254 nm. The results showed that the three chemical markers could be well resolved and that in the selected linear range, all calibration curves of the three chemical markers showed good linearity (R2 ≥ 0.999 8). The recoveries of byakangelicin, imperatorin and isoimperatorin were 100.83%, 100.10% and 103.52%, respectively, and RSD were 1.7%, 0.77% and 0.41% (n = 6), respectively. The data suggested that the developed HPLC method had good reproducibility, robustness, and accuracy, which was suitable for the quality control of Radix Angelicae Dahuricae. Applications of this method showed that the three chemical markers had higher contents in the Bozhou Anhui and Changge Henan than others.

A HPLC method was developed for simultaneouly quantitative analyses of aviprin (1), gosferol (2), 3'R-(+)-hamaudol (3), 3'-O-acetylhamaudol (4) and iso-imperatorin (5) in the rhizome of Angelica polymorpha. The analysis was performed at 25 degrees C on an Agilent Eclipse XDB-C18 analytical column (4.6 mm x 250 mm, 5 microm) with the mobile phase of methanol and H2O in gradient elution [55:45 (0 min)-65:35 (25 min)-95:5 (35 min)]. And the flow rate was 1.0 mL min(-1) with the detection wavelengths of 312 nm (1), 306 nm (2), 300 nm (3), 294 nm (4) and 310 nm (5). Consequently, the reqresion equations were Y = 1.81 x 10(3) X + 7.93 x 10(2) (r = 0.9996), Y = 2.49 x 10(3) X - 2.17 x 10(2) (r = 0.9993), Y = 2.02 x 10(3) X - 1.42 x 10(2) (r = 0.9991), Y = 1.57 x 10(3) X - 0.66 x 10(2) (r = 0.999 7), Y = 2.65 x 10(3) X - 1.47 x 10(2) (r = 0.999 6). And the average recoveries were 99.7% (RSD 0.57%), 100.1% (RSD 1.3%), 100.0% (RSD 1.6%), 99.6% (RSD 1.3%), 99.2% (RSD 0.59%), respectively. The precision, repeatability and stability were all consistent with the request of quantitative analysis. The contents of compound 1-5 in A. polymorpha were determined as 0.525%, 0.044%, 0.046%, 0.043%, 0.15%, respectively. Accordingly, this quantitative analysis method is good for the quality control of A. polymorpha.

Optimum extraction process was established: 21 MPa as extraction pressure, 50 degrees C as extraction temperature, 3 h as time for extraction, 20 mesh as pulverized degree, 6.5 MPa as separation pressure and 30 degrees C as separation temperature.

CONCLUSIONChanges in extraction pressure, temperature, time, pulverized degree and separation pressure affect the extracting results remarkably.
