Antifungal activities of essential oils have been extensively studied and these materials have the potential to replace synthetic biocides. In this study, the chemical composition of Leyland cypress(× Cupressocyparis leylandii), Monterey cypress(Cupressus macrocarpa), Western juniper(Juniperus occidentalis), and Port Orford cedar(Chamaecyparis lawsoniana) foliage oils were determined and their antifungal activities on wood were analyzed. GC-MS analysis showed that monoterpenoids represented more than 90 percent of the oils except Port Orford cedar oil, where monoterpenoids comprised only one third of the oil. Cedar oils were reduced the growth of selected mold fungi and were capable of some inhibition of decay fungi, but could not completely protect wood from stain or decay fungi.

We introduced the oxidation method of Lecithin liposome which induced by Fe2+ and fluorescence chemiluminescence *** method used to determine the ability of the proanthocyanidin extracted from Sanguisorba of inhibit liposome peroxidation,scavenge superoxide anion(O2-.) and hydroxyl free radical(·OH).We carried out a comparative analysis with rutin,extract of Grape Seed and vitamin E(VE) in antioxidant *** revealed in the results,compared the extract of Grape Seeds and VE,the inhibition ratio of proanthocyanidin extracted from Sanguisorba to inhibit liposome peroxidation is 1.62 and 7 times,scavenge superoxide anion(02-.) is 1.6 and 10.15 times and scavenge hydroxyl free radical(.OH) is 1.9 and 29.5 times,*** results demonstrate that proanthocyanidin extracted from Sanguisorba show better antioxidant ability,which further revealed that resource of sanguisorba is more worth exploiting and applying.
