ABSTRACT
O objetivo deste trabalho foi avaliar a eficiência do BLUP (Melhor preditor linear não-viesado) para predizer o desempenho de híbridos com base nos genitores, comparando os resultados obtidos com as análises dialélicas. Para tanto, foram realizados cruzamentos dialélicos entre seis genótipos de feijão: Xan 159, Pérola, BAF 63, IPR Uirapuru, BRS Supremo e BRS Valente. Todas as plantas foram avaliadas quanto aos caracteres de importância agronômica. Os dados obtidos foram submetidos à análise dialélica modelo 1 método I de Griffing (1956) que estima a capacidade geral e específica de combinação, e utilizando o BLUP foram obtidos os valores preditos dos genitores e de seus híbridos. Após foram realizadas análises de correlação entre os BLUP's e os quadrados médios da capacidade geral e específica de combinação. Contudo, concluímos que associação do BLUP às análises dialélicas possibilita identificar populações segregantes promissoras, permitindo rapidez no desenvolvimento de novas cultivares.
The aim of this study was to evaluate the efficiency of BLUP (best linear unbiased predictor) to predict hybrid performance based on parents, comparing the results obtained with the Diallel analysis. For this, were performed diallel crosses among six common bean genotypes: Xan 159, Pérola, BAF 63, IPR Uirapuru, Supreme BRS and BRS Valente. All plants were evaluated for important agronomic characteristics. The data were subjected to diallel analysis model I and method I of Griffing (1956) that estimated the general ability and specific combining, and using BLUP were obtained the values predicted of parents and their hybrids. After correlation analysis was performed between the BLUP's and the mean squares of general ability and specific combining. However, we conclude that the association BLUP Diallel analysis enables the identification of segregating populations, enabling rapid development of new cultivars.

OBJECTIVE: To establish a CGC method for the determination of pyridine in Potassium Dehydroandrograpol-ide Succinate. METHODS: The determination was performed on HP-INNOWAX capillary with column temperature at 100℃. The FID detector was used and the carrier gas was nitrogen. RESULTS:The linear range of Pyridine was 2.46～39.3?g?mL-1 and the average recovery was 98.07%,RSD=4.00(n=9).Its detection limit was 0.2?g?mL-1.CONCLUSION: The method is accurate and rapid, and applicable for the determination of the residual level of Pyridine in Potassium dehydroandrograpolide succinate.
ABSTRACT
Objective: To determine magnolol and honokiol in Huoxiangzhengqi Capsule(oil of Herba Agastachis, oil of Perillae, Pericarpium Citri Reticulatae, Cortex Magnoliae Officinalis, etc.).Methods: A supercritical Fluid Extraction (SFE) has been used to extract magnolol and honokiol in Huoxiangzhengqi Capsule, and CGC was used to analyse the extracts.Results: The average rccovery was 96.81% ( RSD =2.81%, n =5) for magnolol, and 97.75% ( RSD =2.36%, n =5) for honokiol, respectively. Conclusion: The SFE CGC offline method for the analysis of Huoxiangzhengqi capsule is simple, quick and accurate.
ABSTRACT
Objective: To establish a HS CGC method for the analysis of residual petroleum ether (60～90?C) in Kanglaite Capsules.Methods: Headspace sampling, a fused silica analytical column with cross linked 95% dimethyl and 5% diphenyl siloxanes station phase (30m?320?m?0.25?m), column temperature at 40?C, a linear velocity of about 19 cm per second, FID detector.Results: The average recovery is 97.2% (RSD=2.87%, n=5). The minimal detection limit is 2.65?10 -8 g?mL -1 (signal/noise=1.3).Conclusion: The method is simple and accurate, and can be used as a control method for the residual organic solvent in the capsules.
ABSTRACT
AIM: To establish a method for detecting the residual solvents in protopanaxdiol. METHODS: Capillary GC with HP-PLOT-Q column (30 m ? 0. 53 mm ? 1. 0 ?m) was used to determine residual in protopanaxdiol. N,N-dimethyl-acetamide as solvent media,FID detector and nitrogen as the carrier gas. RESULTS: There was a good linearity at the experimental concentration (r = 0. 999 96-0. 999 99),the RSD of precision was less than 6. 0 % . The spotting recovery of the 3 residul,including methol,ethyl acetate and n-butanol,was in the range of 98. 2%-102. 2% ,and its’RSD was 1. 1%-2. 4% . CONCLUSION: The method is simple,accurate and of high sensitivity,can be used for the determination of residual solvents in protopanaxdiol.

ABSTRACT
AIM: To establish the quality standard of Siang Pure Oil (menthol, peppermint oil, camphor, cassia oil, basil oil, etc.). METHODS: TLC was used for the identification of cassia oil and basil oil. Capillary gas chromatography (CGC) was used for the identification and determination of camphor and menthol. RESULTS: The TLC and CGC identification were highly specific. The standard curves of camphor and menthol were linear in the range of 0.1018～0.1832?g, and of 0.5947～1.3875?g, respectively. The average recoveries of camphor and menthol were 102.4%, 99.2% and the RSD were 2.3%, 1.4%, respectively. CONCLUSION: This quality standard is capable of effectively controlling the quality of Siang Pure Oil.
ABSTRACT
Objective To investigate the correlation between bacterial cryptic growth cell(CGC)and irritable bowel syndrome(IBS).Methods The techniques of micro-culture and morphological observation were employed in examination of the CGC in feces specimens of patients suffering from IBS.Furthermore,the animal monitoring tests was applied in the aspects of CGC formation under inducing factors and colonization at local intestinal mucus.Results A great deal of CGC could be observed in the feces of IBS patients and exhibited continuous proliferation characteristics regardless of using or not using antibiotics.And the CGC in feces showed auto-lysis features when the patients suffered from the disease.The monitoring tests demonstrated that the antibiotics often used presently to IBS patients could induce the formation and colonization of intestinal bacterial CGC.Conclusion Based on the experimental and clinical data,we presume that there is a correlation between intestinal bacterial CGC and IBS.
