Chemical Constituents of Bryophytes: Bio- And Chemical Diversity, Biological Activity, and Chemosystematics
ISBN: 9783709110836 / Angielski / Twarda / 2012 / 796 str. Termin realizacji zamówienia: ok. 20 dni roboczych. For some 50 years, Professor Asakawa and his group have focused their research on the chemical constituents of bryophytes and have found that these plants contain large numbers of secondary metabolites, such as terpenoids, acetogenins, and aromatic compounds representative of many new skeletons, which exhibit interesting biological activities. Individual terpenoids, when found as constituents of both a bryophyte and a higher plant, tend to occur in different enantiomeric forms. Professor Asakawa has covered the literature on bryophytes in two earlier volumes of Progress in the Chemistry...

Toxic Plants: Proceedings of the 18th Annual Meeting of the Society for Economic Botany, Symposium on Toxic Plants, June 11-15, 1977
ISBN: 9780231046862 / Angielski / Twarda / 1979 / 195 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. The dependency of the human race on plants as renewable sources of many foodstuffs, drugs, textiles, fuel, and building materials in generally acknowledged. However, the harmful effects produced by certain plant constituents, which result in an increasing incidence of poisoning cases in the United States each year, are not so widely appreciated. This book is not intended to be a comprehensive treatise on all substances from plants that are lethal or otherwise injurious to humans or livestock. Instead, owing to tremendous recent advances in the understanding of the chemical nature of their...

Fortschritte Der Chemie Organischer Naturstoffe / Progress in the Chemistry of Organic Natural Products, Vol. 93
ISBN: 9783709111079 / Angielski / Miękka / 2012 / 264 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Lignans, by convention, are a group of natural products that are formed by linking two phenylpropanoid units (C C units) by oxidative coupling. Most importantly, in 6 3 a lignan, two (C C units) are bound through the central carbon of their side chains, 6 3 0 i. e. the 8 and 8 positions (1, 2). The occurrence of C C -dimers, linked at sites other 6 3 0 than the 8-8 positions, is also known and these compounds have been termed neolignans (3, 4). As these two groups of compounds have close structural as well as biosynthetic relationships, they are often associated together and incorporated...

ISBN: 9783211996607 / Angielski / Twarda / 2010 / 175 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Resin glycosides are part of a very extensive family of secondary metabolites known as glycolipids or lipo-oligosaccharides and are constituents of complex resins (glycoresins) (1) unique to the morning glory family, Convolvulaceae (2). These active principles are responsible for the drastic purgative action of all the important Convolvulaceous species used in traditional medicine throughout the world since ancient times. Several commercial purgative crude drugs can be prepared from the roots of different species of Mexican morning glories. Their incorporation as therapeutic agents in Europe...

ISBN: 9783319456164 / Angielski / Twarda / 2017 / 246 str. Termin realizacji zamówienia: ok. 20 dni roboczych. The first contribution describes apolar and polar molecular fossils and, in particular biomarkers, along the lines usually followed in organic chemistry textbooks, and points to their bioprecursors when available. Thus, the apolar compounds are divided in linear and branched alkanes followed by alicyclic compounds and aromatic and heterocyclic molecules, and, in particular, the geoporphyrins. The polar molecular fossils contain as functional groups or constituent units ethers, alcohols, phenols, carbonyl groups, flavonoids, quinones, and acids, or are polymers like kerogen, amber, melanin,...

Ancistrocladus Naphthylisoquinoline Alkaloids
ISBN: 9783031104565 / Angielski / Twarda / 2023 / 335 str. Termin realizacji zamówienia: ok. 20 dni roboczych. This book describes a unique class of secondary metabolites, the mono- and dimeric-naphthylisoquinoline alkaloids. They exclusively occur in lianas of the palaeotropical Ancistrocladaceae and Dioncophyllaceae plant families. Their unprecedented structures include stereogenic centers and rotationally hindered, and therefore stereogenic, axes. Extended recent investigations on six Ancistrocladus species from Asia, as reported in this contribution, shed light on their fascinating phytochemical productivity, with over 100 intriguing natural products. This high chemodiversity arises from a...
