“…The flavonol aglycones: Kaempferol, quercetin, isorhamnetin, sometimes patuletin, spinacetin and tricin were detected in eight Atriplex species (Sanderson et al, 1988). The presence of two new flavonoid sulphates: kaempferol 3-O-sulphate-7-O-arabinopyranoside and quercetin 3-O-sulphate-7-O-arabinopyranoside from leaves of A. hortensis L. was reported by Bylka et al (2001). For A. littoralis, the new acetylated flavonol glycoside was isolated from the aerial part (Bylka, 2004).…”

Salt-tolerant plants grow in a wide variety of saline habitats, from coastal regions, salt marshes and mudflats to inland deserts, salt flats and steppes. Halophytes living in these extreme environments have to deal with frequent changes in salinity level. This can be done by developing adaptive responses including the synthesis of several bioactive molecules. Consequently, several salt marsh plants have traditionally been used for medical, nutritional, and even artisanal purposes. Currently, an increasing interest is granted to these species because of their high content in bioactive compounds (primary and secondary metabolites) such as polyunsaturated fatty acids, carotenoids, vitamins, sterols, essential oils (terpenes), polysaccharides, glycosides, and phenolic compounds. These bioactive substances display potent antioxidant, antimicrobial, anti-inflammatory, and anti-tumoral activities, and therefore represent key-compounds in preventing various diseases (e.g. cancer, chronic inflammation, atherosclerosis and cardiovascular disorder) and ageing processes. The ongoing research will lead to the utilisation of halophytes as a new source of healthy products as functional foods, nutraceuticals or active principles in several industries. This contribution focuses on the ethnopharmacological uses of halophytes in traditional medicine and reviews recent investigations on their biological activities and nutraceuticals. The work is distributed according to the different families of nutraceuticals (lipids, vitamins, proteins, glycosides, phenolic compounds, etc.) discussing the analytical techniques employed for their determination. Information about the claimed health promoting effects of the different families of nutraceuticals is also provided together with data on their application.

“…2) of all C. bracteosa extracts in this study were separated, identified and quantified by HPLC-DAD-MS n . 20,21 In such plants, the binding reaction of inorganic sulphates to flavonoids is probably one of the mechanisms connected with the biochemical adaptation of species to their environments. They are found mainly in species occurring in coastal and swampy areas rich in mineral salts, as well as in plants occurring in arid habitats.…”

“…In relation to the phenolic compound identification, as seen in Table 1 16,19 Sulphate esters of flavonoids are relatively rare compounds and their functional significance in plant tissues is not clear. 21 Although the phenolic profile of C. bracteosa fruits was reported for the first time in this study, there is another report available, in which two active compounds were identified in the ethyl acetate extracts of C. ulei stems: erythro-2,3-bis(4-hydroxy-3-methoxyphenyl)-3ethoxypropan-1-ol and a known compound, evofolin-B, along with five inactive compounds (betulinic acid, oleanolic acid, pomolic acid, (+)-syringaresinol and ursolic acid). 20,21 In such plants, the binding reaction of inorganic sulphates to flavonoids is probably one of the mechanisms connected with the biochemical adaptation of species to their environments.…”

The seed of the Amazonian fruit Couepia bracteosa exhibits higher scavenging capacity against ROS and RNS than its shell and pulp extracts

Among the large number of scientifically unstudied fruits from the Amazonia biome, Couepia bracteosa acts as an interesting source of bioactive compounds, such as phenolic compounds and carotenoids, which may be used for protecting human health against oxidative damage. For the first time, the phenolic compounds and carotenoids in extracts obtained from the pulp, shell and seeds of C. bracteosa fruits are reported, as well as their in vitro scavenging capacities against some reactive oxygen species (ROS) and reactive nitrogen species (RNS). The shell extract presented the highest phenolic compound and carotenoid contents (5540 and 328 μg per g extract, dry basis, respectively), followed by the pulp and seed extracts. The major phenolic compound was acacetin sulphate (one methoxy and two OH groups) (62%) in the shells; however, only seeds presented apigenin sulphate (three OH groups), in which it was the major compound (44%). The high content of apigenin sulphate may explain why the seed extract had the highest scavenging efficiency against all tested ROS/RNS among the studied extracts. Regarding carotenoids, all-trans-neochrome (17%) and all-trans-β-carotene (16%) were the major carotenoids in the pulp extracts, while all-trans-lutein (44%) was the most prevalent in the shell extracts and all-trans-α-carotene (32%) and all-trans-β-carotene (29%) were the major ones in the seed extracts.

In tro duc tionFlavonoids are one of the most in ter est ing groups of bi o log i cally ac tive nat u ral polyphenolic compounds. They are widely dis trib uted in plants and in plant-de rived bev er ages such as tea and wine. In plants they are in volved in pho to syn the sis as cat alysts of elec tron trans port and as reg u la tors of ion chan nels re lated to photophosphorylation (Havsteen 1983). These com pounds are re spon si ble for the colour ing in plants and are en gaged in a de fence sys tem against in fec tion. They play a def i nite role in attracting of an i mals for pol li na tion and are impor tant fac tors in the re sis tance of plant to in sect attack. The flavonoids ab sorb in 280-315 re gion and thus are ca pa ble of act ing as UV fil ters, thereby pro tect ing the un der ly ing photosynthetic tis sues from dam age (Harborne and Wil liams 2000).Their pres ence in the hu man diet ranges from 20 to 600 mg/day.
