Considering that the anthraquinone compounds with the structure similar to the laccaic acid such as rheinic acid, aloe rheinic acid, have the antioxidant activity or the function of free radical scavenging[18-21], therefore, in this study, we used three different types of free radicals to evaluate the activity of the lac dye on free radical scavenging, and then compare with the ascorbic acid of stronger free radical scavenging activity, to assess the ability of the lac dye to scavenge free radicals in vitro, to provide a reference for its applications on foods. 1 Materials and Methods 1.1 Materials and reagents Lac dye: Mojiang Lac Plant; ascorbic acid (AR): National Pharmaceutical Group Chemical Reagent Co., Ltd.. 1,1-diphenyl-2-DPPH· (Sigma Corporation); 2,2'-Azinobis-(3-ethyl- benzthiazoline-6-sulphonate) (ABTS) (100%): (EMD Biotechnology Co., Ltd); pyrogallol (AR) (National Pharmaceutical Group Chemical Reagent Co., Ltd.); Tris Hydroxy Methyl Aminomethan (THAM) (Shanghai Bo'ao Biological

Because of its vital function in conservation and persistent utilization of forest resources as well as the function in soil and water conservation[6-9], the study of forest debris has becoming one of the valued concerns in forest ecology, soil, hydrology, biogeochemistry and environmental chemistry[10-13].
In different land-use types, vegetation structure and surroundings were different, so the fine debris of organic carbon storage was different.So the organic carbon storage in fine debris was various under different conditions mentioned above.

It is noticeable that there is little to no difference between the ZnO and ZnO-AP, which suggests that 2-aminophenol has a negligible effect on the crystal structure of ZnO.

Introduction Recently polymer/carbon nanotube (CNT) composites have attracted considerable attention and have been used as high performance structure materials, supercapacitors, electromagnetic interference shielding (EMI), wave absorption, optical limiting, ultrafast optical switching, polymer-based light-emitting devices, and super-hydrophobic surfaces owing to unique mechanical, surface and multifunctional properties, and strong interactions with the matrix resulting from the nano-scale microstructure and extremely large interfacial area [1] .
