Pterodon (Fabaceae) species known as “sucupira-branca” are traditionally used in Brazilian medicine. This South American monophyletic genus has delimitation problems. To separate the recognized we described wood anatomy of P. abruptus, emarginatus, pubescens, hybrid (between emarginatus and pubescens) apparicioi, latter two for first time. Wood anatomical studies were undertaken, qualitative qu...

Post-marketing control of Matricaria chamomilla L. and Thymus vulgaris products by reference developed methods

A revision of Gonolobus s.s. (Apocynaceae: Asclepiadoideae: Gonolobinae) in the West Indies is provided based on recent evidence of support for the monophyly of the genus from molecular and morphological data. Ten species are recognized (eight endemic to a single island each). Keys, descriptions, and illustrations are provided for all ten species. The conservation status of each species is prov...

Two novel chitin-binding peptides, designated Pp-AMP 1 and Pp-AMP 2, which had antimicrobial activity against pathogenic bacteria and fungi, were purified from Japanese bamboo shoots (Phyllostachys pubescens) by a simple procedure based on chitin affinity chromatography. They had the common structural features of the plant defensin family, but they could not be grouped in any type of that famil...

The thymus is the primary organ responsible for generating functional T cells in vertebrates. Although T cell differentiation within the thymus has been an area of intense investigation, the study of thymus organogenesis has made slower progress. The past decade, however, has seen a renewed interest in thymus organogenesis, with the aim of understanding how the thymus develops to form a microen...

In this study, the chemical composition of essential oils obtained from aerial parts Thymus longicaulis subsp. naturally grown in Turkey were analyzed by GC and GC-MS differences terms chemotaxonomy discussed. The main compounds T. 1,8-cineole (30.1%), linalool (18.0%), β-pinene (17.3%) (E)-β-ocimene (%12.6%) Hierarchical cluster analysis was performed examining oil studies 34 samples belonging...

A new species of the carpenter bee genus Xylocopa Latreille (Xylocopinae: Xylocopini) is described and figured from two localities in southern Saudi Arabia. Xylocopa (Koptortosoma) sarawatica Engel, sp. n. is a relatively small species similar to the widespread X. pubescens Spinola, but differs in the extent of maculation in males, setal coloration of both sexes, and male terminalia. A revised ...
