Fourteen aromatic and 24 aliphatic acids were determined by GC-MS analysis of acidic fractions obtained from Paeonia peregrina and Paeonia tenuifolia roots. Benzoic acid and its monohydroxy-, dihydroxy- and trihydroxy-derivatives are the main acid components of both Paeonia species. Some fractions could serve as a source of benzoic, 4-hydroxybenzoic, vanillic and gallic acids, as well as of eth...

A new mealybug species, Chorizococcus zoysiaesp. n., feeding on Zoysia tenuifolia (Poaceae), is described from Taiwan. Adult female, third-instar female, second-instar female and first-instar nymph were described and illustrated in this article. Keys are provides to (a) separate this new species from similar species of Chorizococcus and those of same genus on zoysia grasses and (b) to identify ...

In this study, antioxidant and antiproliferative properties of ‘‘Achillea phrygia’’ were investigated. Since the activity B sub-extract from plant’s chloroform extract is higher than other extracts, Achillea phrygia was used in preparation nanoparticles. Characterization nanoparticles made, activities IC50 values only calculated by cell culture studies XTT viability test. According to results, ...

Haplotype phylogenies based on DNA sequence data are increasingly being used to test traditional species-level taxonomies based on morphology. However, few studies have critically compared species limits based on morphological and DNA data, and the methods used to delimit species using either type of data are only rarely explained. In this paper, we review three approaches for species delimitat...

One hundred accessions of a “core collection” Diplotaxis tenuifolia (L.) DC. and Eruca spp. were screened at seedling stage for resistance to downy mildew. Accessions tested the assigned 0–6 interaction phenotypes. All cultivated rocket (Eruca spp.) exhibited resistant (R) response both in cotyledons young leaves. The wild (D. tenuifolia) higher susceptibility than 1st 2nd leaves, with 16 47 cl...

BACKGROUND The root of Polygala tenuifolia, a traditional Chinese medicine, has been used to improve memory and intelligence, while the underlying mechanisms remain largely unknown. In this study, we investigated the protective effects of senegenin, an component of Polygala tenuifolia root extracts, on cognitive dysfunction induced by hepatic ischemia-reperfusion. METHODOLOGY/PRINCIPAL FINDIN...
