Book excerpt: 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 is an outstanding example of the assimilation of botanical drugs from the Americas as substitutes for traditional Old World remedies (3). Even though phytochemical investigations on the constituents of these drugs were initiated during the second half of the nineteenth century, the structure of their active ingredients still remains poorly known for some examples of these purgative roots. During the last two decades, the higher resolution c- abilities of modern analytical isolation techniques used in conjunction with pow- ful spectroscopic methods have facilitated the elucidation of the active principles of these relevant herbal products. This chapter describes the ethnobotanical information associated with the p- gative morning glory species and how traditional usages were instrumental in plant selection for chemical studies. The advantages and limitations of available analy- cal techniques for the isolation, puri?cation, and structure characterization of the individual constituents of these complex glycoconjugates are also discussed.

Fattorusso and published by Springer Science & Business Media. This book was released on 1997-09-30 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volumes of this classic series, now referred to simply as "Zechmeister” after its founder, L. Zechmeister, have appeared under the Springer Imprint ever since the series’ inauguration in 1938. 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. Each contribution is written by a recognized authority in his field and provides a comprehensive and up-to-date review of the topic in question. Addressed to biologists, technologists, and chemists alike, the series can be used by the expert as a source of information and literature citations and by the non-expert as a means of orientation in a rapidly developing discipline.

Book excerpt: The Leguminosae is an economically important family in the Dicotyledonae with many cultivated species, e. g., beans and peas. The family also contains many well-known medicinal plants. It is composed of 17,000 or more species that constitute nearly one twelfth of the world's flowering plants (1). Traditionally the family has been divided into three subfamilies, Caesalpinioideae, Mimosoideae and Papilionoi deae, which are sometimes recognized as separate families Caesalpinia ceae, Mimosaceae and Papilionaceae. The International Code of Botanical Nomenclature permits alternative nomenclatures, the family names being replaced by Fabaceae, Fabales and Faboideae, and this usage will be common (2). Licorice (liquorice, kanzoh in Japanese, gancao in Chinese) is the name applied to the roots and stolons of some Glycyrrhiza species (Fabaceae) and has been used by human beings for at least 4000 years. The earliest written reference to the use of licorice is contained in the Codex Hammurabi dating from 2100 B. C., and the subsequent history in the West has been described in the earlier reviews (3-6). In the Far East, references to the effectiveness of licorice are contained in the "Shen Nong Ben Cao Jing," the first Chinese dispensatory whose original anonymous volumes probably appeared by the end of the third century (7, 8)."
