“…High temperatures may cause stress and alterations in biochemical reactions (ZOBAYED et al, 2005;LIANOPOULOU et al, 2014), triggering energy deviation from the primary to the secondary metabolism. (MÜLLER et al, 2013). Isopentenyl diphosphate (IPP) is the basic unit of terpene establishment (terpene chain) (TAIZ; ZIEGER, 2009) and can be synthesized via methylerythritol phosphate (TOTTÉ et al, 2000).…”

ABSTRACT:The Stevia rebaudiana (Bert) Bertoni is a perennial plant native in the Amambay Hills in the South America. The leaves of this plant produce various natural sweeteners useful to replace the human needs of saccharine. The aims of this study were to evaluate the dry biomass and the glycoside concentration in the Stevia leaves along different growing periods of the growing season to determine the best time to harvest the crops. We selected and identified six groups of 20 plants for analyses. The highest plant yield was found in December, from the first harvest for the groups 3, 4 and 2 with 292.4; 285.2 and 206.7 g m -2 , respectively. The sweetener concentrations and the glycosides ranged within the harvests and the compounds analyzed. The highest concentrations of stevioside (12.16% -group 1 and 11.36% -group 5) and rebaudioside C (2.43% -group 5 and 1.95% -group 1) were found in January while rebaudioside A had the highest concentrations of 7.01% (group 6); 6.16% (group 4) and 6.15% (group 3) in December, February and March, respectively. The environmental conditions have influence in days to harvesting as well as in the concentration of glycosides.

“…Saponins are mainly bioactive compounds in Panax plants, belong to pentacyclic triterpenoids, are synthesized by isoprenoid pathway (Szakiel et al, 2011b) which is affected by mineral nutrients (Müller et al, 2013;Ndamba et al, 1996;Vijay et al, 2009;Zhu et al, 2009a;2009b). Up to now, which step is regulated by mineral nutrients in saponins synthesis pathway is still unclearly (Müller et al, 2013). Several researches demonstrate that saponins synthesis support the carbon/nutrient balance and the growth differentiation balance hypothesis (Müller et al, 2013;Ndamba et al, 1996).…”

Several researches demonstrate that saponins synthesis support the carbon/nutrient balance and the growth differentiation balance hypothesis (Müller et al, 2013;Ndamba et al, 1996). However, several results suggest N application is beneficial to saponins metabolism, but excessive N inhibits saponins synthesis (Vijay et al, 2009;Zhu et al, 2009a;2009b).…”

“…The assumptions tested by a number of studies are being approved, reveal that secondary metabolites especially phenolic compounds are stimulated to synthesize under adverse conditions but restrained under good conditions for growth (Liu et al, 2010a;Liu et al, 2010b;Ibrahim et al, 2011). Similarly, several studies have been conducted on the influence of environmental factors (soil fertility) on saponins concentrations, but the relevance of spaonins metabolism and growing conditions are not consistently (Müller et al, 2013;Vijay et al, 2009;Zhu et al, 2009a;2009b). Müller et al (2013) showed that leaf centelloside concentration in C.asiatica is negatively correlated with herb and leaf yield as well as leaf N concentration, and the respective sapogenins concentrations are negatively correlated with K concentrations.…”

The effects of organic and inorganic N combined application on P.notoginseng cultivation are poorly known. For this reason, we have carried out a pot culture experiment in 2010. The treatments respectively were (1) control (no N input, CK), (2) organic N (ON), (3) half organic N and half inorganic N (1/2ON+ 1/2IN), (4) inorganic N (IN). Plant growth, NPK and secondary metabolites concentration were assayed. Results showed that compared to CK, ON increased plant height, N, P concentration and accumulation and total saponins concentration, but reduce total flavonoids concentration. IN increased shoot and root biomass, N concentration and accumulation, K accumulation, but reduce total flavonoids and saponins concentration. 1/2ON+ 1/2IN had the highest hair root length, root diameter, biomass, N concentration and accumulation, K concentration in roots, total saponins concentration, but had the lowest K concentration in shoots, total flavonoids concentration in shoots and roots. Correlation analysis showed total flavonoids concentration was negative correlated with N concentration and accumulation, K concentration in shoots, but was positive correlated K concentration in roots. Total saponins concentration was negative correlated with K concentration in shoots whereas positive in roots, and was negative correlated with total flavonoids concentration. Totally, organic and inorganic N combined application with the ratio of 50/50 is the best way for growth and saponins of P.notoginseng.

Introduction: The phytochemical composition of plant material governs the bioactivity and potential health benefits as well as the outcomes and reproducibility of laboratory studies and clinical trials. Objective: The objective of this work was to develop an efficient method for the indepth characterisation of plant extracts and quantification of marker compounds that can be potentially used for subsequent product integrity studies. Centella asiatica (L.) Urb., an Ayurvedic herb with potential applications in enhancing mental health and cognitive function, was used as a case study. Methods: A quadrupole time-of-flight analyser in conjunction with an optimised high-performance liquid chromatography (HPLC) separation was used for in-depth untargeted fingerprinting and post-acquisition precursor ion quantification to determine levels of distinct phytochemicals in various C. asiatica extracts. Results: We demonstrate the utility of this workflow for the characterisation of extracts of C. asiatica. This integrated workflow allowed the identification or tentative identification of 117 compounds, chemically interconnected based on Tanimoto chemical similarity, and the accurate quantification of 24 phytochemicals commonly found in C. asiatica extracts. Conclusion: We report a phytochemical analysis method combining liquid chromatography, high resolution mass spectral data acquisition, and post-acquisition interrogation that allows chemical fingerprints of botanicals to be obtained in conjunction with accurate quantification of distinct phytochemicals. The variability in the composition of specialised metabolites across different C. asiatica accessions was substantial, demonstrating that detailed characterisation of plant extracts is a
