In this thesis, two types of medicinal plants in the chemical composition and environmental factors, including the following two aspects: 1 Changbai Equisetum kaempferol content on the spectral reflectance parameters Response: Equisetum Changbai Mountain and kaempferol content spectral reflectance parameters were studied to explore the pros and cons of discriminating quality herbs Equisetum quick way. According reflectance spectra (Unispec-Sc spectrum analyzer) derived several parameters, Equisetum sample cluster analysis were determined by HPLC Equisetum kaempferol content, and analyzes the spectral reflectance parameters and kaempferol Correlation content. The results showed that: blue edge area (SDb), green peak reflectance (Rg) and other parameters and kaempferol content showed a significant negative correlation (r = .0.991, .0.982), 530 ~ 570 nm band reflectance and kaempferol pigment content was also found a significant negative correlation (| r | gt; 0.95). By comparing the blue edge area (SDb), green peak reflectance (Rg), can quickly and easily determine the quality of Changbai Mountain area Equisetum merits. Enhanced 530-570 nm wavelength of the incident light line, can stimulate kaempferol content increases, but need further validation field experiment. 2 Euonymus phytochemical Relationship with local factors: first study the yellow heart euonymus (Euonymus macropterus Rupr.) The chemical composition, the use of chromatographic separation and purification technology, and through spectroscopic identification of chemical structures and physicochemical properties. Euonymus from yellow heart ethanol extract of the roots were isolated 14 compounds were identified as 2-hydroxy Hexacosanoic acid, ethyl ester (1) ,9,12-Eicosadienoic acid (9Z, 12Z) - ,2-hydroxy-3-[ [(9Z)-1-oxo-9-octadecen-1-yl] oxy] propyl ester (2), Table cork alcohol (3), lupeol (4), eicosanol (5), stearyl acid (6), daucosterol linoleate (7) ,10-eicosanol (8), daucosterol (9), β-sitosterol (10), octacosanoic acid (11), is three-dodecane (12), niacinamide (13), is three-tetradecane (14). Compounds 1,2,5,6,7,8,11,12,14 the first time from the genus Euonymus isolated compound 1 for the first time as a natural product isolated. And the use of analysis of variance, discussed my homemade genus Euonymus chemical composition and by regional factors affecting the relationship between the results showed that different types of plants and geographical distribution of species triterpenoids and sesquiterpene chemical composition ratio the difference is significant, and plants sesquiterpenoids and triterpenoids, steroids and other chemical composition ratio as a significant negative correlation.
