lated to the bitterness of THTPM. However,further verification is needed later by optimizing the concentration gradient and expanding the sample size.The quality of honeysuckle has always been an important factor in industrial development. Flowering is one of the elements for the variation of the effective components in honeysuckle. We can conveniently recognize whether the commodity is mixed with blossomed honeysuckle in the form of medicinal material. However,it is hard to identify whether the products are mixed with blossomed honeysuckle in the form of powdersince visual identification traits are missing. Therefore,this study aims to seek an effective method of odor-based distinguish for identifying the quality of honeysuckle powder in different ratios by using Heracles Ⅱ ultra-fast gas phase electronic nose.The powdered samples were prepared with flower buds and fully blooming flowers in different proportion. Gas chromatograms of the powder were obtained by HeraclesⅡ ultra-fast gas phase electronic nose. Through analyzing the data of chromatograms,we have concluded that the qualitative results of the prepared powder were almost the same,and there existed differences in the components content. Meanwhile,the hexanal odor appeared to be the critical factor in identifying honeysuckle powder quality among the flavor of all possible compounds. Also,we have applied PCA,DFA and CQ to identify and classify the variety of the powder based on the chromatogram data. Finally,it is realized that the powder was rapidly identified and classified into three grades based on the proportion of flowering honeysuckle. The predicted concentration value for the first class is less than 3,the value of is not less than 3 and less than 5 for the second class,and more than 5 for the third class. In summary,the results obtained by the study suggest that Heracles Ⅱ ultra-fast gas phase electronic nose analysis can be used as a rapid identification method for the quality of honeysuckle powder. At the same time,it can provide a reference for the quality classification of honeysuckle based on flowering degrees.Cultivated ginseng in the farmland would become the mainly planting mode of Panax ginseng. However,there are relatively few cultivation ginseng varieties for farmland in China. Correlative analysis of qualitity and agronomic traits of P. ginseng cultivation in the farmland could provide a reference for the selection of excellent germplasm and new variety breeding of P. ginseng. In this study,the main index of saponin and agronomic traits of 4-6 years' samples were analyzed by UPLC and measured. The results show that there was significant difference in agronomic indexes of Damaya. The coefficient of variation of the root length( CV = 41. 97%) and fresh weight( CV = 31. 81%) were maximum,and the coefficient of variation of the stems thickness( 16. 72%) and root thickness were minimum. There was a significant correlation between yield and root thickness( P less then 0. 05). There was significant difference in drug yield of different harvest years( P less then 0. 05),and the yield of 6-years was 31. 52%-39. 69% higher than 4-years. However,there wasn't significant difference in total ginsenosides between 4 and 6 years old P. ginseng,but there was significant difference in ginseng Rg2,Rc and Rb2( P less then 0. 05),and the ginsenoside contents of different harvesting years were accorded with the criterion standards of 2015 Chinese Pharmacopoeia. There was no significant correlation between the saponin and the agronomic trait,while there was positive correlation with root thickness( P less then 0. 05). Therefore,the stem diameter was positive correlation with yield of P. ginseng. Selection of the stem thickness of seedlings is beneficial to the increase of the yield and breeding of P. ginseng.The aim of this study was to study the effects of different light intensity on the growth,biomass accumulation and distribution,chlorophyll content and effective components of Uncaria rhynchophylla seedlings,and explore the suitable light intensity conditions for artificial cultivation of U. rhynchophylla seedlings. Three-year-old U. rhynchophylla seedlings were used as experimental materials. Four light intensity levels( 100%,70%-75%,30%-35%,5%-10%) were set up with different layers of black shading net. With the decrease of light intensity,the results showed that the plant height,basal diameter and biomass( root,stem,leaf and hook) of U.rhynchophylla seedlings exhibited the trend of " increase-decrease". Under 70%-75% light intensity,the plant height,basal diameter,biomass( root,stem,leaf,hook) of U. rhynchophylla seedlings were significantly higher than those of other treatments( P less then 0. 05);under 5%-10% light intensity,the plant height,basal diameter and biomass( root,hook) of U. rhynchophylla seedlings were significantly lower than those of other treatments( P less then 0. 05). With the decrease of light intensity,the chlorophyll content of U. rhynchophylla seedlings increased gradually under 100% light intensity,the chlorophyll content of U. see more rhynchophylla seedlings were the smallest,while under 100% light intensity,its chlorophyll content was the highest. With the decrease of light intensity,the contents of rhynchophylline and isorhynchophylline in different organs of U. rhynchophylla seedlings varied under 30%-35% light intensity,the contents of rhynchophylline and isorhynchophylline in hooks and rhynchophylline content in stems were the highest; under 5%-10% light intensity,the contents of rhynchophylline and isorhynchophylline in leaves and stems of U. rhynchophylla were the highest. In conclusion,70%-75% light intensity is suitable for seedling growth and biomass accumulation,and 30%-35% light intensity is suitable for the accumulation of effective components in U. rhynchophylla seedlings.Leech has a good anticoagulant activity and is one of the raw materials for treatment of many cardiovascular and cerebrovascular diseases. This study was based on in vitro anticoagulant experiments( APTT and PT) to investigate the effects of lead contamination on the anticoagulant effect of leech. At present,the Hirudo circulating in the market are dominated by Whitmania pigra,therefore Wh. pigra were cultivated under a different lead pollution for 50 days. Then,the effects of Wh. pigra extract,extracting from different cultivating environment,on activated partial thrombin time( APTT) and prothrombin time( PT) were determined by automatic coagulation instrument. The results showed that the Wh. pigra extract significantly prolonged the APTT compared with the saline group.The APTT of the lead-high residual Wh. pigra was shorter than that of the blank Wh. pigra. The Wh. pigra extracts from different treatment groups had little effect on PT. The results showed that the lead residue in the Wh. pigra increased with the increase of lead in the cultured soil,the lead residual of the Pb-H group was( 10.
