    ABSTRACT: To set up the quality standard of Chimonanthus nitens leaf. Five compounds were identified by double-development thin layer chromatography, the plate was colorized with 1% vanillin-H2 SO4 solution and warmed up in 110 degrees C; The content of four compounds was determined by HPLC, the chromatography separation was performed on the Elite hypersil ODS2 (250 mm x 4.6 mm, 5 microm) column with gradient elution. The mixture of acetonitrile and water as the mobile phase at a flow rate of 1.0 mL/min was used, the detection wavelength was 344 nm and the column temperature was set at 40 degrees C. The TLC identification was highly specific and spots were clear. In HPLC method, the calibration curve was linear in the range of 5.665 - 56.65 microg/mL for scopoletin (r = 0.9999), the average recovery was 97.06% and RSD was 1.27%; The calibration curve was linear in the range of 2.4312 - 24.312 microg/mL for isofraxidin (r = 0.9999), the average recovery was 102.86% and RSD% was 0.93%; The calibration curve presented a linear range from 2.444 - 24.44 microg/mL for scoparone (r = 0.9999), the average recovery was 102.18% and RSD was 1.81%. The standard curve presented a linear range from 9.012 - 90.12 microg/mL for rutin (r = 0.9992), the average recovery was 104.44% and RSD was 4.2%. These methods are reproducible, sensitive and simple and can be used to control the quality of Chimonanthus nitens leaf.

    ABSTRACT: Amygdalin was catalytic degraded by extracellular enzymes mixture from Aspergillus niger and a novel product, phenyl-(3,4,5-trihydroxy-6-methyl-tetrahydro-pyran-2-yloxy)-acetonitrile (PTMT), with high antitumor activity was identified and purified. To measured the Pharmacokinetic of amygdalin and its products, a simple and rapid SPE-HPLC method was set up. The analysis was performed on an Agilent HPLC system with a C18 ODS column (250 × 4.6 mm i.d.) by gradient elution with 0.05% formic acid in water and 0.05% formic acid in acetonitrile as the gradient mixtures. The flow rate was 1ml/min, the detection wavelength was 215 nm and the column temperature was kept at 25°C. The HPLC assay was carried out within 9 min. The retention times of amygdalin, mandelonitrile, prunasin, PTMT andbenzaldehyde were 3.14, 5.93, 6.82, 7.35 and 8.33 min, respectively. The mean absolute recoveries of three analysts were over 98%. The limit of detection and limit of quantification for were 0.02 and 0.04 μg/ml for amygdalin and benzaldehyde, 0.03 and 0.05 μg/ml for mandelonitrile, and 0.03 and 0.04 μg/ml for prunasin and PTMT.

    ABSTRACT: The quality of Morindaofficinalis, which has been used as a Yang-tonic agent for a long time in China, can be evaluated. A double-development high performance thin layer chromatography (HPTLC) method has been established to simultaneously analyze quality and quantity of seven inulin-type oligosaccharides (DP=3-9) in Morindaofficinalis. The chromatography was performed on a silica gel 60 plate with the 7:5:2:1 proportion (v/v) of n-butanol-isopropanol-water-acetic acid for the first and second developments, respectively. The bands were visualized by the reaction with aniline-diphenylamine-phosphoric acid solution and analyzed by densitometric TLC at 540 nm. Quantification of seven oligosaccharides was achieved by densitometry at 540 nm. The investigated standard sugar had good linearity (R2>0.99) within test ranges. The amounts of seven oligosaccharides were calculated by the relative correction factor (RCF). Therefore, the developed TLC method could be used for quality control of Morindaofficinalis.

    ABSTRACT: In the polymeric title compound, {[Co(CHO2)2(C12H8N2)(H2O)]·H2O}n, the cobalt ion is coordinated by two N atoms from one chelating 1,10-phenanthroline ligand, three formate O atoms and one water O atom, giving a cis-CoN2O4 octahedral geometry. Pairs of formate anions bridge the metal atoms into a chain. A network of O—H...O hydrogen bonds helps to establish the packing.

    ABSTRACT: In the title compound, C(11)H(10)N(3)O(4)S(+)·C(2)Cl(3)O(2) (-), the benzene ring forms an angle of 85.21 (13)° with the pyridinium ring. The nitro group is nearly coplanar with its attached benzene ring [dihedral angle = 3.68 (12)°]. In the crystal structure, strong N-H⋯O hydrogen bonds link the ion-pairs. The packing is further consolidated by weak C-H⋯O inter-ations.

    ABSTRACT: To optimize the preparation process and to set up the quality standard of Ephedra sinica Dispensing Granules. Nine experiments were carried out by L9 (3(4)) orthogonal design. Ephedra sinica Dispensing Granules was identified by TLC and the content of ephedrine was determined by HPLC. The optimal extraction process was as follows: the water that 10 times of Ephedra sinica, was decocted 3 times and each time was sustained for 1.5 hours. The linear relationship of ephedrine hydrochloride was at the range of 0.0081 - 0.1377 microg (r = 0.999 9). The average recovery was 100.25% ( RSD = 2.24%, n = 6). The extraction process is scientific. The method is available with a good reproducibility and can control the quality of Ephedra sinica Dispensing Granules.

    ABSTRACT: This paper reviewed application of chitin and its derivatives in pharmaceutical industry of traditional Chinese medicine in recent years. Chitin and its derivatives could be used as a clarificant, retaining active substances, stabiliting preparation, reducing the heavy metals of traditional Chinese medicine extraction. Because of their churacteristics in biodegradation, biocompatibility and its tendency to film easily, chitin and its derivatives was ideal assistant materials in traditional Chinese medicine. Its application was largely enhanced after chitosan was modified. The problems and prospects of the application of chitin and its derivatives were also discussed.
