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).

The volumes of this classic series, now referred to simply as "Zechmeister" after its founder, L. The volumes contain contributions on various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers.

In order to make further progress in elucidating the mechanism of NOS catalysis it will be essential to throw light on the interaction between the enzyme and its substrate.

This situation drastically changed with the advent and commercial availability of broadband ex citation and Fourier transform methods, giving natural-abundance 13C n.

Lignans, by convention, are a group of natural products that are formed by linking two phenylpropanoid units (C C units) by oxidative coupling. 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).

This is mainly due to their in vitro radical scavenging (21) or antioxidant (22) biological properties, while the polymeric proanthocyanidins in red wine have been implicated in protection against cardiovascular disorders (23), e.

Epothilones have received unusual attention over the past ten years. laulimalide, eleutherobin, peluroside, discodermolide) the epothilones have significant advantages, above all very high activity in the nanomolar range and low susceptibility towards multidrug resistance.

This work on the progress in the chemistry of organic natural products offers examination on topics such as: the naturally occuring coumarins; variations of ring-attached five-carbon units found in coumarins; and variations of five carbon units attached to carbon and oxygen in coumarins.

Saponins are complex molecules made up of sugars linked to a triterpenoid or a steroid or a steroidal alkaloid. This review incorporates newer trends in isolation and structure determination of triterpenoid saponins, new triterpenoid saponins isolated and biological properties of these products reported during the period late 1989-mid 1996.
