Three new acylated R1-barrigenol triterpene glycosides, 1-3, were isolated from the seeds of Pittosporum angustifolium Lodd. together with four known glycosides, 4-7, containing R1- and A1-barrigenol backbones. On the basis of spectroscopic, spectrometric, and chemical analyses the novel compounds were named pittangretosides N-P and established as 21beta-acetoxy-22alpha-angeloyloxy- (1), 21beta...

The aim. Today we are witnessing the actualization of research on plant sources for pharmaceutical and food industries. It is caused by a significant increase in demand these types resources. Therefore, variety case studies aimed at identifying characteristics resources, becoming more actual too. In accordance with this need, present work aims to identify relationship between content flavonoids...

Blueberries originated from North America and the predominant cultivated species are Vaccinium corymbosum (Northern Southern Highbush), ashei (Southern Rabbiteye), angustifolium (Lowbush). Consumer’s demand for high-quality blueberry fruits has driven interest to better understand flavor chemistry of blueberry. Forty-five previously identified aroma contributing compounds were further investiga...

1. The leaf tannin of willow-herb [Chamaenerion angustifolium (L.) Scop.] has been isolated and separated into two fractions of differing solubility. 2. The tannin contains a penta-O-galloyl-beta-d-glucose core to which further galloyl groups are depsidically bound. 3. The unfractionated tannin contains an average of 10.5 galloyl groups/glucose molecule; the soluble fraction has on average 7.6 ...

The aim of this study was to examine the effect of a polyphenol-rich extract (PrB) of Vaccinium angustifolium (wild blueberries) introduced intraperitoneally (i.p.) at 30 (PrB30) and 60 (PrB60) mg/kg body weight for 7 days, on cognitive performance, brain oxidative status and acetylcholinesterase activity in adult, male, 3-4-month-old Balb-c mice. Evaluation of rodent learning and memory was as...

Ceropegia palustris Pursh and Lyonia maritima Elliott (Apocynaceae: Asclepiadoideae) are currently recognized as synonyms of Funastrum angustifolium (Pers.) Liede & Meve. The diminutive vine, one of the most readily recognizable taxa among a number of taxonomically difficult climbing milkweeds in the southeastern United States, occurs primarily in swamps, hammocks, and salt marshes. A neotype i...
