High-performance liquid chromatographic coupled with variable wavelength detection (HPLC-VWD) has been developed for simultaneous determination of 5 analytes including ellagic acid, quercetin, kaempferol-3-O-beta-D-rutinoside, tiliroside and kaempferol, and high-performance liquid chromatographic with an evaporative light scattering detector (HPLC-ELSD) has been established to determine goshonoside-F5 in extract of Rubi Fructus. Chromatographic separations were carried out on an Agilent ZORBAX SB-C18 column (4.6 mm x 250 mm, 5.0 microm). All calibration curves of reference standards revealed good linearity (R2 > 0.999 5) within the concentration ranges tested. The method limits of detection ranged 0.297-90.144 ng and the method limits ofquantitation ranged 0.990-300.480 ng, respectively. Recoveries of 6 analytes were from 97.11% to 101.7%, with RSD less than 2.1%. The result shows that amounts of the 6 analytes in the samples from 16 localities were found to be different. The higher latitude of growing environment, the more ellagic acid in herb. The content of total flavonoids in sample from east localities were higher than that in middle and west localities, and the content of goshonoside-F5 in Bozhou, Anhui province was higher than others. This method was found to be simple, accurate, sensitive with good repeatability. Those results might serve as a sound foundation for further study, quality control and application of Rubi Fructus.

To explore the influence of matrix materials in complicate ingredients on traditional Chinese medicine and investigate the excipients selection model based on balanced release characteristics of multicomponents, the influence of HPMC (K4M, K15M, K100M) and Carbomer (934P, 971P, 974P) was illustrated by testing in vitro release of ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in Panax notoginseng saponins (model drug, PNS). According to in vitro release results of PNS matrix tablets in water and artificial intestinal juice, the release curves were analyzed with Peppas equation and simulating factor (f). Significant differences in k value and n value among ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 existed in various formulations. The release behaviors from various excipients could be described with Non-Fickian transport or super Case II transport pattern. The f2 values for ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in 971P matrix tablet containing 30% Carbomer 971P were 74.91, 53.45, 57.89 in water and 79.35, 55.51, 51.89 in artificial intestinal juice, respectively. The release profiles fit for the regulation of FDA. The result revealed that the balanced release rates of Rg1, Rb1 and R1 in 971P matrix tablet were obtained.

OBJECTIVETo study the effect of Scutellaria baicalensis stem-leaf total flavonoids (SSTF) on cardiocyte apoptosis of neonatal rats induced by hypoxia/reoxygenation and its action of mechanism. METHODS Sixty one to two days old rats, male or female, were selected. Hypoxia/reoxygenation injured model was established in cultured cardiocytes of neonate rats. The cultured neonatal rat cardiocytes were divided into 5 groups, i.e., the normal control group, the hypoxia/reoxygenation injury group (as the model group, cultured cardiocytes were exposed to hypoxia 2 h and subsequently reoxygenated for 4 h), the hypoxia/reoxygenation injury plus 50 mg/L SSTF group (as the low dose SSTF group), the hypoxia/reoxygenation plus 100 mg/L SSTF group (as the middle dose SSTF group), and the hypoxia/reoxygenation plus 200 mg/L SSTF group (as the high dose SSTF group). The cell viability was detected by methyl thiazolyl tetrazolium (MTT) colorimetry. The apoptosis of cardiocytes was determined by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) and the apoptosis rate calculated. The Bcl-2 and Bax protein expressions were determined by immunohistochemistry.

RESULTSCompared with the normal control group, the cell viability, Bcl-2 protein contents and Bcl-2/Bax decreased, the apoptosis rate and Bax protein contents increased in the model group (all P<0.01). Compared with the model group, the cell viability, Bcl-2 protein contents and Bcl-2/Bax increased, while the apoptosis rate and Bax protein contents decreased in each SSTF treated group (P<0.05, P<0.01). Compared with the low dose SSTF group, significant difference existed in each index of the high dose SSTF group (all P<0.05).

CONCLUSIONSSSTF had protection on hypoxia/reoxygenation induced cardiocyte apoptosis. Its protective mechanism might be correlated with its up-regulation of the expression of Bcl-2 protein ahd down-regulation of the expression of Bax protein.
