China Journal of Chinese Materia Medica 2014;39(3):520-525
This study aim to reveal the total pharmacokinetics of rhein and chrysophanol after oral administration of Quyu Qingre granules (QUQRG) in normal and acute blood stasis rabbits, to identify the pharmacokinetics differences between two groups of rabbits and to evaluate the applicability of the total statistical moment analysis. Based on the concentrations of rhein and chrysophanol in plasma determined by an established HPLC method, and the calculation of main total pharmacokinetic parameters, this study found that total pharmacokinetic parameters VRT, value of blood stasis group is lager than that of normal group and the difference is significant Compared with normal group, total pharmacokinetic parameters AUC,, MRT,, t1/2t, and Vt value of blood stasis group is lager, while the k, and CL, value is smaller. The findings indicated that the absorbed and released time of rhein and chrysophanol was accelerated and the total absorptive amount of these two compounds was increased in rabbits with acute blood stasis, compared with the normal rabbits. Total quantity statistical moment analysis can combine the pharmacokinetics of rhein and chrysophanol and express the pharmacokinetic behavior of these two compounds in QUQRG. The parameters in this paper can provide reference frames for the follow-up development of QUQRG.

To investigate the mechanism of agarwood formation in Aquilaria sinensis induced by Lasiodiplodia theobromae, the fermentation liquor of L. theobromae was analyzed qualitatively and quantitatively by gas chromatography-mass spectrometry (GC-MS). JAs were detected in the fermentation liquor. The effect of the fermentation liquor on the abundance of sesquiterpenes in the callus of A. sinensis was analyzed by solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS). And the fermentation liquor stimulated alpha-guaiene, alpha-humulene and delta-guaiene biosynthesis in calli. It was inferred that L. theobromae produced JAs, which resulted in a significant increase of sesquiterpenes in A. sinensis.

In order to reveal genetic diversity of domestic Andrographis paniculata and its impact on quality, genetic backgrounds of 103 samples from 7 provinces in China were analyzed using SRAP marker and SNP marker. Genetic structures of the A. paniculata populations were estimated with Powermarker V 3.25 and Mega 6.0 software, and polymorphic SNPs were identified with CodonCode Aligner software. The results showed that the genetic distances of domestic A. paniculata germplasm ranged from 0. 01 to 0.09, and no polymorphic SNPs were discovered in coding sequence fragments of ent-copalyl diphosphate synthase. A. paniculata germplasm from various regions in China had poor genetic diversity. This phenomenon was closely related to strict self-fertilization and earlier introduction from the same origin. Therefore, genetic background had little impact on variable qualities of A. paniculata in domestic market. Mutation breeding, polyploid breeding and molecular breeding were proposed as promising strategies in germplasm innovation.

This paper is aim to investigate the pharmacokinetics and absolute bioavailability of neoline in Beagle dogs, and provide a theoretical basis for further study. Ethyl acetate was used for liquid-liquid extracting after 10% ammonia alkalizing. The method of UPLC-Q-TOF-MS was established for the determination of neoline plasma concentrations. Beagle dogs were orally or intravenously administered with neoline for pharmacokinetic and absolute bioavailability study. Good linear relationship of neoline was found over the range of 0.1-4 mg x L(-1) (R2 = 0.9982) and 2-100 microg x L(-1) (R2 = 0.9945). Intra-and inter-day precision, expressed as the relativestandard (RSD) were less than 5.0%. Accuracy, expressed as the relative error (RE) was within 90.0%-115%. The recovery of neoline in dog plasma was more than 80%. After 6 mg x kg(-1) for ig and 1 mg x kg(-1) for iv administration of neoline, the main pharmacokinetic parameters were analyzed with Winnonlin software. t(1/2) were (313.88 +/- 63.18), (236.33 +/- 229.84) min, and AUC(0-infinity) were (58,027.40 +/- 14,132.69), (473,578.02 +/- 82,333.08) min x microg x L(-1) for ig and iv administration respectively. The absolute bioavail ability was (73.15 +/- 10.29) %. The method of UPLC-Q-TOF-MS described in the report was sensitive, reliable and specific, and suitable for pharmacokinetic study of neoline in Beagle dog. The high absolute bioavailability of neoline in dog suggested good absorption of neline which was worth of further investigation.

OBJECTIVETo observe morphological changes of enteric nervous system (ENS)-interstitial cells of Cajal (ICC)-smooth muscle cell (SMC) structure injury in deep muscle nerve plexus offunctional dyspepsia (FD) rats, and the repair of Shuwei Decoction (SD) on it, and to explore its effecton FD.
METHODSTotally 72 rats were randomly divided into the control group, the model group, the lowdose SD group, the medium dose SD group, and the high dose SD group, the Mosapride group, 12 ineach group. Rats in the low dose SD group, the medium dose SD group, and the high dose SD group were intragastrically fed with SD at 0.767, 1.534, 3.068 g/mL, respectively. Rats in the Mosapride group were intragastrically fed with Mosapride (1.37 mg/kg). FD rat model with Gan depression Pi deficiency syndrome (GDPDS) was established using complex pathogenic factors. Corresponding liquors were respectively administered to rats in corresponding groups from the 3rd day after modeling. Distilled water(10 mL/kg) was administered to rats in the control group and the model group, once per day for 14 successive days. Rats were sacrificed and small intestine tissues collected for observing ENS-ICC-SMC structure injury using immunofluorescence double labeling, laser scanning confocal microscope, and transmission electron microscope at day 15. Repair of SD on it was also observed.
RESULTSENS-ICC SMC structure was incomplete, with obvious injury in mutual link of ICC, ICC, SMC, and connecting structure. ENS-ICC-SMC structure was more complete in high, medium, and low dose SD groups, with close link of ICC and SMO. Their connecting structures were in good conditions.
CONCLUSIONSD could keep the integrity of ENS-ICC-SMC structure by promoting regeneration and morphology of ICC, thereby, improving gastrointestinal movement disorder and showing therapeutic effect on FD.
