ABSTRACT
Objective: To evaluate the quality of Limonitum from different mineral genesis and select its high quality mineral resources by analyzing its mineral compositions and content. Method: The mineral compositions and content of different samples were analyzed by polarizing microscope and X-ray diffraction,and goethite content was taken as the evaluation index. SPSS 16.0 statistical software was used for hierarchical cluster analysis of the mineral compositions in different samples. Result: Limonite,quartz,illite and mica kaolinite were the main components of Limonitum from leaching disseminated type. Sedimentary type limonite was mainly composed of limonite,quartz and albite. Residual-alteration type limonite was mainly composed of limonite,quartz,diopside and carnallite. The content of goethite in limonite was highest (46.4%) in sedimentary type limonite from Jiangxi province,followed by that in leaching-disseminated type from Jiangsu province (17.9%) and leaching-disseminated type from Shandong province (0.5%). The content of sedimentary goethite was higher than 12.0%and the content of leaching-disseminated type goethite was between 0.5%and 18.0%, with significant difference; and the content of residual-alteration type was below 3.0%. Cluster analysis of mineral components in different samples showed that 6 samples of leaching-dissemination type were clustered into one group,3 samples of sedimentation type were clustered into one group,and 2 samples of residual-alteration type were clustered into one group. Conclusion: The quality of sedimentary type Limonitum in Jiangxi is the best. Generally,the quality of sedimentary type is better than that of leaching-disseminated type, and the quality of leaching disseminated type is better than that of residual-alteration type.
ABSTRACT
Models were established in mice with warfarin sodium method, and their bleeding time and hemostasis time were measured by tail cutting method and slide method respectively. Rats were administered for 15 consecutive days to measure their recalcification time, plasma viscosity, platelet adhesion rate, platelet aggregation rate and other blood indexes. As compared with the blank group, the bleeding time was prolonged in model groupn(P<0.05). As compared with the model group, the results showed that the positive vitamin K, the leaching type water decoction and the sediment type decoction could significantly shorten the bleeding time (P<0.01); positive vitamin K significantly (P<0.01) shortened clotting time, and the leaching type water decoction, the sediment type water decoction and the sediment type powder could also shorten the clotting time (P<0.05). As compared with blank group, low dose, medium dose of leaching type water decoction, medium dose of powder, high dose of sediment type decoction and low dose of drug residues could reduce plasma viscosity (P<0.05), and high dose of leaching powder and low dose of water decoction could significantly reduce (P<0.01) plasma viscosity. As compared with blank group, Limonitum leaching type decoction high dose group could significantly reduce the platelet adhesion rate (P<0.05), while sediment type water decoction could significantly increase the platelet adhesion rate (P<0.05); the high dose of leaching type water decoction, high dose of drug residues, low dose of leaching type powder and low dose of drug residues could decrease the platelet aggregation rate (P<0.05), while high dose of leaching type water decoction and high dose of the powder could increase the platelet aggregation rate (P<0.05). Analysis of mineral compositions was conducted by polarized light microscopy and X-ray diffraction (XRD). The results of the both methods showed that Limonitum mineral compositions contained goethite, quartz, and kaolinite, and sedimentary type also contained illite and albite. Sediment type of Limonitum showed better hemostatic effect, which may be related to the high content of goethite and illite.
