The purpose of this paper was a comparative to study population variability of individual and group composition of biologically active phenol compounds in leaves of Lonicera caerulea subsp. pallasii (Ledeb.) Browic. in natural population of south taiga subzone of West-Siberian plain, Altai Mauntains and in conditions of introduction in the forest-steppe of the Novosibirsk Priobye. Chlorogenic acid and its isomers neochlorogenic acid and dicaffeoyl quinic acid, glycozides of luteolin, apigenin and quercetin, apigenin and luteolin in leaf extracts of L. caerulea subsp. pallasii was identified by HPLC-MS. The quantitative variations content of compounds (classes of biologically active polyphenols and their individual components) depending on vegetation conditions have been explored using HPLC. The major components of L. caerulea subsp. pallasii leaves are rutinoside quercetin, chlorogenic acid and dicaffeoyl quinic acid. The content and ratio of the major phenolic compounds and the composition of their minor components varied depending on the location and conditions of plant growth. The content of derivatives of hydroxycinnamic acids and flavonols increased significantly in response to changes in habitat conditions in natural populations and in the introduction into the forest-steppe zone. The flavones are the least variable compounds in plant leaves. The results can be useful in elaboration of practical recommendations for picking medicinal and food plants in different vegetation conditions

The aerial parts of Scorzonera aristata Ramond ex DC., collected in the South Tyrolean Dolomites, yielded the flavonoids quercetin 3- O-glucoside, rutin, and isoorientin, and the caffeic acid derivatives chlorogenic acid, 4,5-dicaffeoyl quinic acid, and 3,5-dicaffeoyl quinic acid. Sub-aerial parts contained caffeic acid methyl ester, 3,5-dicaffeoyl quinic acid, and the triterpenes 3α-hydroxyolean-5-ene, lupeol, and magnificol. Chemosystematic implications of the isolated compounds are discussed briefly.

Key Enzyme

This investigation cultured Cecropia obtusifolia cells in suspension to evaluate the effect of nitrate deficiency on the growth and production of chlorogenic acid (CGA), a secondary metabolite with hypoglycemic and hypolipidemic activity that acts directly on type 2 diabetes mellitus. Using cell cultures in suspension, a kinetics time course was established with six time points and four total nitrate concentrations. The metabolites of interest were quantified by high-performance liquid chromatography (HPLC), and the metabolome was analyzed using directed and nondirected approaches. Finally, using RNA-seq methodology, the first transcript collection for C. obtusifolia was generated. HPLC analysis detected CGA at all sampling points, while metabolomic analysis confirmed the identity of CGA and of precursors involved in its biosynthesis. Transcriptome analysis identified differentially expressed genes and enzymes involved in the biosynthetic pathway of CGA. C. obtusifolia probably expresses a key enzyme with bifunctional activity, the hydroxycinnamoyl-CoA quinate hydroxycinnamoyl transferase and hydroxycinnamoyl-CoA shikimate/quinate hydroxycinnamoyl transferase (HQT/HCT), which recognizes shikimic acid or quinic acid as a substrate and incorporates either into one of the two routes responsible for CGA biosynthesis.

Condensing Enzyme

Cell-free extracts of Aspergillus niger, N.R.C. 233, have been shown to contain the enzymes necessary to catalyze the synthesis of citrate from ATP, acetate, and oxalacetate. The "condensing enzyme", which catalyzes the condensation of acetyl-coenzyme A and oxalacetate to yield citrate, has been isolated and purified approximately 50-fold by a combination of steps involving ammonium sulphate fractionation and calcium phosphate gel adsorption.
