        [Objective]This study aimed to study the coagulation effect of Callicarpa nudiflora. [Method]The effects of Callicarpa nudiflora on blood coagulation system of mice were investigated by measuring prothrombin time(PT),thrombin time(TT),activated partial thromboplastin time(APTT)and plasma fibrinogen(FIB).[Result]Compared with the control group,the crude extracts and eluted parts of Callicarpa nudiflora all significantly shortened PT,APTT and TT,and increased the content of FIB in mice.[Conclusion]The crude extracts and eluted parts of Callicarpa nudiflora have a coagulation-promoting effect through affecting several links of the coagulation process in mice.

        C allicarpa nudiflora Hook.et Arn. (Verbenaceae: Callicarpa)is mainly produced in Hainan Province of China,and it is a local medicinal material in Hainan. Callicarpa nudiflora is also distributed in Guangdong and Guangxi of China[1],Vietnam,India and Malaysia.Callicarpa nudiflora is bitter and slightly acrid in taste,and is neutral in nature. The roots,stems and leaves of Callicarpa nudiflora can all be used as medicine,and they have detoxifying,anti-bacterial,anti-inflammatory,stopping bleeding and dissipating blood stasis,anti-swelling functions.Callicarpa nudiflora is mainly used to treat acute infectious hepatitis,suppurative inflammation,respiratory and gastrointestinal bleeding and thrombocytopenic purpura embolism.If Callicarpa nudiflora is used externally,it can treat burns,rheumatism swelling,bruises and swelling,traumatic bleeding,tuberculosis hemoptysis and gastrointestinal bleeding.Callicarpa nudiflora is one of the common herbs in the Li ethnic group in Hainan Province[2-5]. There have been currently rare researches on effective coagulation promoting parts of Callicarpa nudiflora and the relevant mechanisms.Studies have reported that flavonoids is the main active ingredient in Callicarpa nudiflora that promotes coagulation[6]. In order to explore effective coagulation-promoting parts of Callicarpa nudiflora and the relevant mechanism,the effects of main active ingredients from Callicarpa nudiflora on blood coagulation in mice were investigated,and the relevant coagulation mechanism was primarily studied.

        Materials and Methods

        Materials

        Test animal The SPF Kunming mice,with weight of 18-22 g,were provided by the Hunan Slack King of Laboratory Animal Co.,Ltd(Produc-tion license number:SCXK (Xiang)2009-0004).

        Drugs and reagents The dry powder extract of Callicarpa nudiflora was provided by the Hainan Jiuzhitang Pharmaceutical Co.,Ltd.The Anluoxue was produced by the Changzhou Yabang PharmaceuticalCo., Ltd(batch number:1103030).The PT,TT,APTT and FIB assays were produced by the Beijing Shidi Scientific Instruments Co.,Ltd.The sodium citrate,methanol and other reagents were all of analytical grade.

        Equipment and instruments The used equipment and instruments included AT-200 electronic balance(METTLER,Germany),DL-0601 electronic balance (Xiangyi,Hunan,China),LG-PABER coagulation factor analyzer(Shidi,Beijing,China),QD highspeed centrifuge (Heima,Zhuhai,China), R-200 rotary evaporator(Buchi Labortechnik AG CH-9230)and Agilent 1100 series HPLC (Agilent,USA).

        Methods

        Extraction and separation of chemical ingredients A certain amount(500 g)of dry powder extract of Callicarpa nudiflora was completely dissolved in a certain amount of deionized water (w/v,1/20).The solution was first filtered through bag and then through cotton plug.The obtained filtrate was loaded on HP-20 macroporous resin,and then eluted to colorless with deionized water, 5% methanol, 40% methanol, 60% methanol and 80%methanol,respectively.The obtained deionized water elute,5% methanolelute,40% methanol elute,60%methanol elute and 80%methanol elute were dried in a rotary evaporator at 50℃.And then,the deionized waterextract,5% methanol extract,40%methanol extract,60%methanol extract and 80% methanol extract were obtained.The HPLC analysis showed that the components of non-adsorbed fraction by macroporous resin and of 5% methanol elute were all contained in the deionized water elute,so the three parts were collectively referred to as water elute.

        Effects of Callicarpa nudiflora on blood coagulation system in mice

        The Kunming mice were randomly divided into control group(equivalentvolume distilled water),crude dry extract group (1.0 g/kg),water elute group (1.0 g/kg),40%methanol elute group(1.0 g/kg),60%methanol elute group (1.0 g/kg),80%methanol elute extract(1.0 g/kg)and positive control group (Anluoxue,0.004 g/kg).There were total 12 mice in each group.The water and drugs were given to mice by gavage one a day (0.2 ml/10 g body weight),which lasted for 7 continuous days.Blood was sampled from eyeballs of mice 60 min after the last administration.The blood samples were immediately mixed with certain amounts of 109 mmol/L sodium citrate(v/v,9/1).They were centrifuged at 3 000 rpm for 10 min.Subsequently,the obtained plasmas were transferred to new tubes.For each plasma sample,the PT,TT,APTT and FIB were measured using LG-PABER coagulation factor analyzer.The decrement rates of PT,TT and APTT and increment rate of FIB were calculated according to the following formulas:

        Decrement rate of PT(%)=(Average PT in the control group-Average PT in the administration groups)/ Average PT in the control group×100;

        Decrement rate of TT (%)=(Average TT in the control group-Average TT in the administration groups)/ Average TT in the control group×100;

        Decrement rate of APTT (%)=(Average APTT in the control group-Average APTT in the administration groups)/Average APTT in the control group×100;

        Increment rate of FIB (%)=(Average FIB content in the administration groups-Average FIB content in the control group)/Average FIB content in the control group×100.

        Data processing and statistics The data were analyzed using SPSS 11.5.The final data were expressed as±s.T-test was conducted for two independent samples,whileANOVA was conducted for pairwise comparisons among multiple samples.When P value was less than 0.05,the difference was considered to be statistically significant.

        Results and Analysis

        As shown in Table 4,after a 7-d administration,the FIBs in the crude dry extract group,water elute group,40% methanolelute group,60% methanolelute group and 80% methanol elute group were increased by 52.2%,42.6%,21.7%,27.8%and 18.3%,respectively (P<0.01)compared with that in the control group.No significant differences were observed in FIB between the crude dry extract group and several elute groups.

        Conclusions and Discussion

        Currently,there have been some products made from extracts of Callicarpa nudiflora on the market,such as Luohuazizhu capsule,Luohuazizhu particle,Luohuazizhu tablet,anti-inflammatory suppository and compound casuarinas tablet[7-8].These different types of preparations are commonly made from extracts or crude water extracts of Callicarpa nudiflora, which have dark colors and miscellaneous components.The coagulation promoting factions of Callicarpa nudiflora and their chemical composition are still unclear.The chemical base for coagulation effect of Callicarpa nudiflora is still unknown,greatly hindering the development and promotion of medicinal products of Callicarpa nudiflora.Prothrombin time(PT)can accurately and effectively reflect the performance of extrinsic coagulation system;thrombin time (TT)can effectively reflect the performance of endogenous coagulation system;activated partial thromboplastin time (APTT)reflects the common performance of extrinsic and endogenous coagulation systems;plasma fibrinogen(FIB)reflect coagulation effect indirectly through the effects of Callicarpa nudiflora on fibrinolytic system[9-10].In this experiment,Kunming mice were treated as the research object,and the effects of Callicarpa nudiflora on blood coagulation system of experimental animal were investigated by measuring PT,TT,APTT and FIB.The results showed that the crude dry extract of Callicarpa nudiflora could significantly shorten the PT,APTT and TT,and increase the FIB content in mice.It suggests that Callicarpa nudiflora achieves the coagulation effect through affecting both extrinsic and intrinsic coagulation pathways.Compared with the control group,various elutes of Callicarpa nudiflora showed more obvious coagulation effects,indicating that various elutes of Callicarpa nudiflora all have coagulation-promoting effects.

        In conclusion,the crude extract and various elutes of Callicarpa nudiflora all have better coagulation effects,and they achieve the coagulation-promoting effects mainly through endogenous thrombin, exogenous thrombin and both extrinsic and intrinsic coagulation pathways,as well as the effects on fibrinolytic system.
