“…grandiflorum (Reynaud et al, 1985;Reynaud and Raynaud, 1986). The most interesting observation, however, was the report of derivatives of 8-hydroxyapigenin and 8-hydroxyluteolin in D. grandiflorum (Reynaud et al 1983;Raynaud, 1984, 1986).…”

“…Acetates are common, but other aliphatic acids are encountered, malonic and succinic for example. Singly acetylated flavone or flavonol glycosides have been reported from Arnica (Merfort, 1986(Merfort, , 1988aMerfort and Wendisch, 1987), Chrysactinia (Harborne et aI., 1991), Chrysanthemum (Hu et aI., 1994), Doronicum (Reynaud et aI., 1985;Reynaud and Raynaud, 1986), Helenium and Plummera (Wagner et aI., 197Ic), Hymenoxys (Wagner et aI., 1972h), Matricaria (Kunde andIsaac, 1979; Redaelli et aI., 1980; Pietta et aI., 1987) and Senecio (Piegay et aI., 1986). Chalcones and aurones have also been found to occur as acetylated glycosides in a few species.…”

This book is dedicated to:Arthur Cronquist Outstanding plant systematist and major contributor to understanding taxonomic relationships within Asteraceae and Ralph E. Alston (1925Alston ( -1967) Visionary natural products chemist and geneticist who pioneered the use of chemical data in studies of plant systematics and evolution PrefaceCertainly many of the readers of this book will remember the early developments of chemosystematics in the late 1950s. We ourselves remember the excitement of these new data bearing on plant interrelationships. The hopes were high, the techniques were rapidly evolving, the quantities of data were large, and young workers were eagerly enthusiastic. Some even went so far as to predict that chemical data would soon replace morphological information as the basis for plant classification. These overly zealous predictions did not materialize, of course, as the history of plant systematics has amply shown during the past two centuries. If there is any distinct characteristic of systematics it is synthesis, as Lincoln Constance (1964) called it, the "unending synthesis." New tools generate new data and provide insights on additional dimensions of plant relationships. This will never change-we will continue to discover new tools and new data in the years ahead, and they will continue to be incorporated into the predictive general reference system of classification.The earlier efforts in chemosystematics focused on secondary plant products: alkaloids, betacyanins, carbohydrates, cyanogenic glycosides, glucosinolates, lipids, terpenoids, and especialiy flavonoids. The latter were particularly well suited for chemosystematic investigation for several reasons: ease of isolation and characterization, small amounts of plant material needed for analysis, stability of compounds especially through routine preparation of herbarium specimens, and low cost to obtain useful information. As a result of these considerable advantages, literally thousands of studies on use of flavonoids in plant systematics have been published. Although now with the present zest for macromolecular data from DNA restriction sites and sequences, there are fewer workers and laboratories dedicated to flavonoid chemosystematic studies; twenty years ago they were the new currency of exciting data in plant systematics.Because of many workers historically interested in the sunflower family, Asteraceae (or Compositae), in part due to its large size (approximately 23,000 species;Bremer, 1994), and because hundreds of flavonoid compounds were discovered in this family, many chemosystematic investigations have been completed on various taxa. Many studies came from the laboratories of R. A. Alston, B. L. Turner, and T. J. Mabry in the Department of Botany ...

“…The three others were the minor methoxylated flavones 5,7,4'-trihydroxy-8,3'-dimethoxyflavone, galangustin and jaceosidin, which had not previously been reported for the Kalanchoe genus [40]. These flavones are common in the Asteraceae family [41], but methoxylation at the C-8 position is rare when compared with methoxylation at C-6 or C-7 of the A ring. Despite the unusual methoxylation at C-8, there is one example described for the Crassulaceae family.…”

The Kalanchoe genus (syn. Bryophyllum), family Crassulaceae, comprises 125 species, most of them native to Madagascar. The great importance of several of these species for the traditional medicine in several regions of the World, esspecially India, Africa, China and Brazil, stimulated research programs into these plants from both a pharmacological and chemical point of view. The present review focuses on the main results obtained during the last decade on the secondary metabolites isolated from these species-endowed or not with a specific biological profile-with emphasis on flavonoids. The distribution of these molecules in the genus will be summarized and special attention will be given to K. brasiliensis and K. pinnata, two species well-known for healing inflammatory and infectious processes. Ornamental Kalanchoe species are also discussed as a potential source of bioactive compounds. This review covers the period 1970-2008.

“…Flavonoids were also present in D. pardalianches, [15] D. macrophyllum [24] and D. corsicum. [15] It is quite interesting to evidence the presence of tremetone derivatives (32 -42) in D. austriacum, [11][12] D. hungaricum, [19] D. macrophyllum [21] and D. pardalianches [20] and of pyrrolyzidine alkaloids (70 -73) in D. columnae [14] and D. macrophyllum (Figure 3). [22] Finally, two coumarins (79 and 80) (Figure 3) were identified in the roots of D. macrophyllum [25] and several carotenoids (81)(82)(83)(84)(85)(86)(87)(88) were detected in the flowers of D. carpathicum (Figure 4).…”
