“…The most differentiating compounds were quercetin, kaempferol, eriodictyol and apigenin. Higher relative reduction in flavonoids was observed in the sensitive genotype, which may indicate that the stability of flavonoid content is important in maintaining higher antioxidant activity under water stress (Djoukeng et al 2008). Wu and co-workers showed that it was possible to use isoflavonoids to discriminate between closely related soybean genotypes.…”

Influence of abiotic stresses on plant proteome and metabolome changes

Plant responses to abiotic stresses are very complex phenomena with individual characteristics for various species. Abiotic stresses (e.g. drought, salinity, flooding, cold, heat, UV radiation, heavy metals, etc.) strongly affect plant growth and development. It is estimated that they are the cause of more than 50 % of crop yield losses. Abiotic stresses are known to activate a multigene response resulting in the changes in various proteins and primary and secondary metabolite accumulation. Therefore, proteomic and metabolomic approaches are becoming very important and powerful tools used in studying plants' reaction to various stimuli. Precise analysis of proteome and metabolome is essential for understanding the fundamentals of stress physiology and biochemistry. In this review, we focus on recent reports concerned to the influence of abiotic stresses on changes in the level of different protein groups and metabolite classes. Basic information about physicochemical methods applied to qualitative and quantitative analyses of biopolymers and natural products is also briefly presented.

“…Among aglycone forms, quercetin, naringenin and hesperitin are the main flavonoids. Whereas, the glycoside forms can be further classified into rutinosides and neohesperidosides (Djoukeng et al, 2008). Neohesperidosides (e.g., naringin, neohesperidin and neoeriocitrin) contain a sugar neohesperidose (rhamnosyl-a-1, 2 glucose) and they are bitter in taste, while rutinosides (rutin, hesperidin and didymin) contain a disaccharide residue e.g., rutinose (ramnosyl-a-1,6 glucose) which makes them tasteless (Macheix et al, 1990).…”

WHAT ARE FLAVONOIDSP hytochemicals are the substances found naturally in all fruits, vegetables and medicinal plants that, ingested daily or rarely, may exhibit a potential for modulating the human metabolism in a way favorable for the preclusion of chronic and degenerative diseases. These days, many studies are conducted on thousands of phytochemicals that may have important physiological and biochemical effects. Among phytochemicals, several compounds, including flavonoids, polyphenols, stilbenes, carotenoids and anthocyanins, are known to be important for a number of health promoting effects. Flavonoids have aroused enormous interest in the Review ArticleAbstract | Flavonoids are phytochemicals derived from plants that known to possess several surprising health effects. They have been divided into several sub-classes, among those isoflavones (soy flavonoids) and flavanones (citrus flavonoids) have aroused great interest due to their immense availability and multidimensional properties. They exert their effects both as purified molecules and as plant extracts. Their well known properties includes anti-inflammation, antioxidation, antimicrobial, antiallergic and immunomodulation, have indicated both in animal and human models. Their modulatory role in several biological processes has also been identified like oxidation, detoxification of enzymes, apoptosis, host immune system and several others. Their potential to interfere with numerous cellular processes such as protection of genomic vitality suggest that flavonoids may used as dietary compounds for promotion of health and preclusion of several infectious and non-infectious diseases. They are known to enhance the gut morphology and functionality, mucosal and cellular immunity, immune organs size and amelioration of heat stress in farm animals; that suggested them health promoting phytochemicals for animal production.

“…The diethyl ether fraction was chromatographed on a Diaion HP-20 column and HPLC to obtain 8, 14, and 15. The known compounds (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) were identified based on spectroscopic data as hypolaetin 7-O-b-D-glucopyranoside (6) [18,19], luteolin (7) [20], acacetin (8) [21], hypolaetin (9) [22], luteolin 7-O-[6 00 -O-(trans-caffeoyl)]-b-D-glucopyranoside (10) [20,23] [20], luteolin 7-O-b-D-glucuronopyranoside (12) [24], luteolin 7-O-rutinoside (13) [25,26], 12-O-demethylcryptojaponol (14) [27], 6a-hydroxydemethylcryptojaponol (15) [28], and incanide B (20) [29]. Four phenylethanoid glycosides, acteoside (16), isoacteoside (17), martynoside (18), and stachysoside (19) were identified by comparison with compounds isolated previously from Leucosceptrum japonicum by our group [30] (Fig.…”

A diterpenoid diglucoside (12,19-di-O-β-D-glucopyranosyl-11-hydroxyabieta-8,11,13-triene-19-one), isoscutellarein 7-O-[β-D-xylopyranosyl-(1→2)]-β-D-glucopyranoside, isoscutellarein 7-O-[α-L-rhamnopyranosyl-(1→2)]-β-D-glucopyranoside, hypolaetin 7-O-[6″-O-(p-E-coumaroyl)]-β-D-glucopyranoside, hypolaetin 7-O-[6″-O-(E-caffeoyl)]-β-D-glucopyranoside, and 15 known compounds were isolated from aerial parts of the Mongolian medicinal plant Caryopteris mongolica. The cholinesterase-inhibitory activities of the constituents were estimated. The abietane diterpenoids (12-O-demethylcryptojaponol and 6α-hydroxydemethylcryptojaponol) showed potent inhibitory activity against acetylcholinesterase from human erythrocytes and electric eel, and against butyrylcholinesterase from horse serum.
