A new species of a strikingly coloured xanthid crab of the genus Neoliomera Odhner, 1925, is described from coral reefs in Guam, Taiwan, and the Hawaiian Islands. The new species is allied to N. pubescens (H. Milne Edwards, 1834), and N. demani Forest & Guinot, 1961, but differs in the form of the carapace armature, frontal margin, structure of the chela, proportions of the ambulatory merus and...

Eleven new triterpene saponins, ilexpublesnins C–M (1–11), along with ten known analogues were isolated from the roots of Ilex pubescens. Their structures were elucidated on the basis of extensive spectroscopic analysis, including 1D and 2DNMR experiments. Compounds 1, 2, 10, and 11 contain a 24-aldehyde, which is rare for triterpene saponins from Ilex. These compounds were evaluated in vitro f...

Five new triterpene saponins, Ilexpublesnins N-R (1-5), along with seven known analogs were isolated from the root of Ilex pubescens. Their structures were elucidated on the basis of extensive spectroscopic analysis, including 1D and 2D NMR experiments. Ilexpublesnin N (1) possessed a rare 20-hydroxyursolic acid scaffold from natural resource. These compounds were evaluated in vitro for their c...

Background In the Romanian flora, several species of the Betula genus are present, especially European white birch (B. pendula, syn. B. verrucosa) and downy birch (B. pubescens, syn. B. alba). Rare species are B. nana and B. humilis. In Southern Romania, the sensitization to Betulaceae pollen in patients with allergic rhinitis is less frequent than that to Poaceae pollen. The flowering season o...

This paper reports mass spectra and linear temperature programmed retention indices (I(T)) for 31 esters of mono- and sesquiterpene alcohols with hydroxycinnamic acids. In this study, 14 phenylpropenoids were synthesized by esterification of terpenols with p-coumaric, ferulic, caffeic and sinapinic acids. Other phenylpropenoids were semi-quantitatively isolated by column chromatography from exu...
