“…1) were isolated, and their structures were determined to be cyanidin 3-sophoroside-5-glucoside (ranging from 0.8% of the total anthocyanin contents calculated from the HPLC peak area at 530 nm, A), (Idaka et al, 1987;Saito et al, 1995Saito et al, , 2008. In addition to the above five anthocyanins, four new anthocyanins (1: 3.8%, 2: 1.1%, 3: 15.4%, 4: 39.9%) were detected in the extract as shown in Figure 1.…”

“…By comparison with these studies we found that the monoacylated pigment petanin has a comparable stability to other anthocyanins with aromatic mono-or di-acylation, as platyconin (Goto et al, 1983;Saito et al, 1985), shisonin and alatanin C (Yoshida et al, 1991), gentiodelphin and the dicaeylated cyanidin derivatives from Ipomoea purpurea (Saito et al, 1985(Saito et al, , 1995.…”

“…For the pH region 5±7 it has been shown that simple anthocyanins are unstable and are quickly decolourised by hydration at the 2-position of the anthocyanidin skeleton (Brouillard, 1988). Most of the reports treating stability of pure anthocyanins under pH in¯uence, deal with the stability of acylated anthocyanins in weak acid or neutral aqueous solutions (Goto et al, 1983(Goto et al, , 1984Saito et al, 1985Saito et al, , 1995Idaka et al, 1987a;Yoshida et al, 1991Yoshida et al, , 1992. It has been shown that these types of anthocyanins (mostly di-or poly-acylated) are more resistant to hydration, and hence possess a higher colour stability in weakly acidic or neutral solutions.…”

This study on anthocyanin colour variation (intensity, l max , 4) over the pH range 1±9 during 60 days of storage, was conducted on petunidin 3- C. Compared to cy3glc, petanin aorded higher colour intensity and higher or similar stability throughout the whole pH range. At pH 4.0, 84% of petanin was intact after 60 days storage at 10 C, while the corresponding solution of cy3glc was totally degraded. At pH 8.1 the colour intensity of petanin was even higher than at the lowest pH values. The visible l max absorption of petanin after 5 days at pH 8.1 at 10 C was similar or higher than the corresponding absorptions of the fresh solutions of cy3glc at any pH. The use of anthocyanins like petanin as food colorants in slightly alkaline products (bakery, milk, egg, etc.) should therefore be consideredÐat least in products with limited storage time kept in a refrigerator. #

“…Others glycoresins called marubajalapins I-XV were isolated from the jalapin fraction of the serial part (leaves and stems) of Pharbitis purpurea (I. purpurea) (Ono et al, 1992b). From the flowers of this species were isolated cyanidins and pelargonidins (Saito et al, 1995; (46), also isolated from I. batatas and I. asarifolia, showed antioxidant activity (Kano et al, 2005). In study for investigation of new souces of ergoline alkaloids within the genus Ipomoea, I. purpurea was alkaloid-negative species, although previous reports indicated presence of ergoline alkaloids.…”

Approximately 600-700 species of Ipomoea, Convolvulaceae, are found throughout tropical and subtropical regions of the world. Several of those species have been used as ornamental plants, food, medicines or in religious ritual. The present work reviews the traditional uses, chemistry and biological activities of Ipomoea species and illustrates the potential of the genus as a source of therapeutic agents. These species are used in different parts of the world for the treatment of several diseases, such as, diabetes, hypertension, dysentery, constipation, fatigue, arthritis, rheumatism, hydrocephaly, meningitis, kidney ailments and infl ammations. Some of these species showed antimicrobial, analgesic, spasmolitic, spasmogenic, hypoglycemic, hypotensive, anticoagulant, anti-infl ammatory, psychotomimetic and anticancer activities. Alkaloids, phenolics compounds and glycolipids are the most common biologically active constituents from these plant extracts.
