Introduction Rosa species are known by their richness in bioactive compounds useful in cosmetic, perfumery, food and phytotherapy. These metabolites are influenced by several factors accordingly affecting the plant properties in different environments. Objective Exploration of polyphenolic composition and antioxidant activity of stem extracts from Rosa moschata Herrm., R. canina L. and R. sempervirens L. growing in different northern areas in Tunisia. Methods Phytochemical composition was carried out by means of high‐performance liquid chromatography diode‐array detector (HPLC‐DAD) and HPLC‐DAD‐ESI‐MS (electrospray ionisation mass spectrometry). Antioxidant activity was measured using the DPPH (1,1‐diphenyl‐2‐picrylhydrazyl) radical scavenging assay, the FRAP (ferric reducing antioxidant power) test, the TEAC (Trolox equivalent antioxidant capacity) and the ORAC (oxygen radical absorbance capacity) assays. Results Rosa stem profiles were dominated by flavonols but qualitative variation was recorded between sections (Caninae and Synstylae). Aromadendrin‐O‐hexoside‐deoxyhexoside, quercitrin and quercetin 3‐O‐glucoside were identified as the major compounds of R. sempervirens, R. moschata and R. canina, respectively. Quantitative differences were found between species, provenances and extracts either for the individual compounds or for the total phenolic contents. This variability was also highlighted in Rosa scavenger ability results. The highest mean values were recorded by methanolic extracts of R. moschata from Bizerte (TEAC and FRAP) and R. canina for DPPH. However, for ORAC assay, the most active extract was obtained by ethyl acetate from stems of R. canina. Conclusion Results allow concluding that stems of R. sempervirens, R. moschata and R. canina could present a new natural residual source of bioactive phytochemicals, to be employed as additives in pharmaceutical products or in cosmetic and food preparations.

High-yield common buckwheat 'cv. Fengtian 1' (FT1) and tartary buckwheat 'cv. Jingqiao 2' (JQ2) were selected to investigate the characteristics of the grain-filling process and starch accumulation of high-yield buckwheat. FT1 had an average yield that was 43.0% higher than that of the control 'cv. Tongliaobendixiaoli' (TLBDXL) in two growing seasons, while JQ2 had an average yield that was 27.3% higher than that of the control 'cv. Chuanqiao 2' (CQ2). The Richards equation was utilized to evaluate the grain-filling process of buckwheat. Both FT1 and JQ2 showed higher values of initial growth power and final grain weight and longer linear increase phase, compared with respective control. These values suggest that the higher initial increasing rate and the longer active growth period during grain filling play important roles to increase buckwheat yield. Similar patterns of starch, amylose and amylopectin accumulation were detected in common buckwheat, leading to similar concentration of each constituent at maturity in FT1 and TLBDXL. Tartary buckwheat showed an increasing accumulation pattern of amylose in developing seeds, which differed from that of starch and amylopectin. This pattern led to a significant difference of the concentrations of amylose and amylopectin at maturity between JQ2 and CQ2, the mechanisms of which remained unclear. Nevertheless, both FT1 and JQ2 showed increased starch, amylose, and amylopectin accumulation during the physiological maturity of grains. The results suggest that prolonging the active grain-filling period to increase carbohydrate partitioning from source to seed sink can be an effective strategy to improve buckwheat yield.

“…It has a well‐balanced amino acid profile with a good amount of lysine, which is generally recognized as the first limiting amino acid in wheat and barley (Ahmed and others 2013). Besides its high‐quality proteins, buckwheat seed is also rich in other bioactive components such as saponins, phytosterols, squalene, polyphenols, and fagopyritols (Bystricka and others ). These components might be beneficial for treating some chronic human diseases such as diabetes and hypertension as well as other cardiovascular ailments.…”

Germination is considered to be an effective process for improving the nutritional quality and functionality of cereals. In this study, changes of nutritional ingredients, antinutritional components, chemical composition, and antioxidant activities of buckwheat seeds over 72 h of germination were investigated, and the reasons for these changes are discussed. With the prolonged germination time, the contents of crude protein, reducing sugar, total phenolics, total flavonoids, and condensed tannins increased significantly, while the levels of crude fat, phytic acid, and the activity of trypsin inhibitor decreased. Phenolic compounds, such as rutin, vitexin, isovitexin, orientin, isoorientin, chlorogenic acid, trans-3-hydroxycinnamic acid, and p-hydroxybenzoic acid increased significantly during the germination process, which may be due to the activation of phenylalanine ammonialyase. The improvement of flavonoids led to significant enhancement of the antioxidant activities of germinated buckwheat. Germinated buckwheat had better nutritional value and antioxidant activities than ungerminated buckwheat, and it represented an excellent natural source of flavonoids and phenolic compounds, especially rutin and C-glycosylflavones. Therefore, germinated buckwheat could be used as a promising functional food for health promotion.
