Natural enemies can be significant sources of mortality for herbivorous insects and therefore important agents of natural selection. One might expect selection to favor herbivores that escape from their natural enemies into enemy-free space. Although this is an appealing idea, it has received little empirical support, and no studies have documented enemy-free space as part of a nonagricultural,...

Leaves and stems of three different herbs from two different families were used to extract phenolic compounds and the bioactivity of the extracts was evaluated by using 1, 1-diphenyl-2-picrylhydrazyl or DPPH scavenging ability or their antioxidant activities. Extract from leaves of mint, which belongs to Lamiaceae family contained 1.24 mgGAE/100 mL of total phenolic compounds and 34.21% antioxi...

A novel, simple and accurate fingerprint method was developed using high-performance liquid chromatography-photodiode array detection (HPLC-DAD) for the quality control of Qianghuo, a Tibetan folk and Chinese herbal medicine used as a diaphoretic, an antifebrile and an anodyne. For the first time, the feasibility and advantages of employing chromatographic fingerprint were investigated and demo...

China contains some of the world's greatest diversity of Apiaceae (Umbelliferae), with ten endemic genera. Our previous investigation into the phylogenetic relationships of Chinese Apiaceae subfamily Apioideae, based exclusively on nrDNA ITS sequences, revealed several major clades heretofore unrecognized in the subfamily and confirmed the phylogenetic placements of five endemic genera. To furt...
