New cardenolides from the seeds of Adonis aestivalis.
Chemical investigation of the seeds of Adonis aestivalis has led to the isolation of a new cardenolide (3β,5α,14β,17β-tetrahydroxycard-20,22-enolide) (1), two new glycosides (2, 3) of 1, and a new strophanthidin hexaglycoside (4), together with a known compound, strophanthidin 3-O-β-D-glucopyranoside (5). The structures of 1-4 were determined by 1D- and 2D-NMR spectroscopic analysis and the res...
متن کاملCoronography with adaptive optics: the ADONIS coronograph
The combination of adaptive optics and coronographic techniques providing at the same time high angular resolution and high dynamic range is a powerful tool to study the close environment of bright objects in different fields of astrophysics (search for brown dwarfs and giant extra-solar planets around nearby stars, search for circumstellar disks, study of AGB outflows, etc). We present in this...
متن کاملTwo New Cyototoxic Cardenolides from the Whole Plants of Adonis multiflora Nishikawa & Koki Ito.
A phytochemical investigation of the whole plants of Adonis multiflora Nishikawa & Koki Ito. resulted in the isolation and identification of two new cardenolides--adonioside A (1) and adonioside B (6)--as well as four known cardenolides: tupichinolide (2) oleandrine (3), cryptostigmin II (4), and cymarin (5). Their structures were elucidated on the basis of NMR, MS, and IR spectroscopic analyse...
متن کاملMulti-Agent control system for the ADONIS adaptive optics instrument
ADONIS is a complex but user-friendly adaptive optics (AO) instrument for the European Southern Observatory 3.6-m telescope. ADONIS is composed of several interacting parts, including the astronomer. Multiple parameters innuence the system performance and they are diicult to handle by the astronomer. A multi-agent, distributed, and message oriented control system is designed. The communication ...
متن کاملnew semigroup compactifications via the enveloping semigroups of associated flows
this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.
