It's a common phenomenon llial two kinds or more than two kinds of herbs belong lo different parts of the same plant. Lonieera Japonica Mos, Lonicera Japonica caulis and Lonicera Japonica I'olium are the typical representative of this phenomenon. They belong lo different parts of the Lonicera jajxynica Tliuiih. This paper reviewed the research progress on pharmacological effects and their differences among them. Il was found that the research mainly concentrated on Lonicera Japonica Mos, and the others were ignored. However, some pharmacological effects in leaves are stronger than that of flowers and stems, such as antibacterial, anti-bird flu and antioxidant activity. Lonicera Japonica l los is mainly used for the treatment of respiratory tract virus infection while Lonicera Japonica Caulis is mainly used for the treatment of hepatitis virus infection, respectively. Finally, main problems and suggestions on pharmacological effects among them were also discussed.

The dried flower buds or initial flowers of Lonicerae Japonicae Flos and Lonicerae Flos, which belong to different species of Lonicera or Caprifoliaceae, are usually taken to clear away heat and toxic material and treat the exopathogenic wind-heat. They are two different herbs, and due to various reasons, there are far more controversies. This paper reviews the research on the chemical constituents and their differences between Lonicerae Japonicae Flos and Lonicerae Flos. Both of them contain the similar chemical constituents, such as organic acids, flavonoids, triterpenoidal saponins, iridoids, volatile oils and trace elements. But there are also differences between them. The main differences：Lonicerae Japonicae Flos contains a wealth of iridoids and flavonoids, while Lonicerae Flos contains more kinds of triterpenoidal saponins; the content of chlorogenic acid in Lonicerae Flos is significantly higher than that of Lonicerae Japonicae Flos; the content of rutin, luteoloside,luteolin-7-O-β-D-galactoside and lonicerin in Lonicerae Japonicae Flos is much higher than that of Lonicerae Flos; the content of Fe and Ni in Lonicerae Japonicae Flos is higher, while the content of Mn is higher in Lonicerae Flos. Finally, main problems and suggestions on chemical composition between Lonicerae Japonicae Flos and Lonicerae Flos were also discussed.

To study the effect of gas-turbine green discoloring and drying processing method on the quality of various Lonicerae Japonicae Flos herbs. DIKMA DiamonsilTM-C18 column (4.6 mm x 250 mm, 5 microm) was adopted using HPLC Waters 1525 and eluted with acetonitrile and 0.1% phosphate acid as the mobile phase. The flow rate was 1.0 mL x min(-1) , the column temperature was 25 degrees C the detection wavelength was 355 nm. After being processed by the gas-turbine green discoloring and drying method, tetraploid Lonicerae Japonicae Flos showed a green color. The contents of chlorogenic acid and galuteolin were 5.31% and 0.105% , both significantly higher by 18.0% and 32.1% than those of diploid Lonicerae Japonicae Flos processed by the same method. The content of chlorogenic acid in tetraploid Lonicerae Japonicae Flos processed the gas-turbine green discoloring and drying method were also remarkably higher than that of tetraploid and diploid Lonicerae Japonicae Flos processed by traditional processing method of natural drying. The gas-turbine green discoloring and drying processing method is a new-type drying method suitable for tetraploid Lonicerae Japonicae Flos. Under the condition of gas-turbine green discoloring and drying processing, tetraploid Lonicerae Japonicae Flos shows much higher quality than Lonicerae Japonicae Flos, suggesting that it is a good variety worth popularizing and applying.
