“…Two minor compounds, 41 and 43 , exhibited a pseudomolecular ion [M‐H] − at m/z 463 and a fragment ion at m/z 301 corresponding to two quercetin hexosides. Compound 48 ( t r = 32.7 min) was characterised by UV maxima at 264 nm and 343 nm, which is typical for kaempferol 3‐ O ‐glycosides . The pseudomolecular ion at m/z 593 gave a main fragment ion at m/z 285 attributed to kaempferol, and the loss of 308 amu was due to cleavage of the hexosylrhamnoside sugar moiety.…”

The compounds were tentatively assigned as nicotiflorin (kaempferol-3-O-rutinoside) or kaempferol-3-O-robinobioside (galactosylrhamnoside), which were both identified in Fraxinus sp.…”

Introduction In European traditional medicine, common ash leaf infusion is recommended by European Medicines Agency to treat minor articular pain and to increase the amount of urine for flushing minor urinary complaints. However, a comprehensive ultra‐high‐performance liquid chromatography diode array detector electrospray ionisation tandem mass spectrometry (UHPLC‐DAD‐ESI‐MS/MS) analysis of this pharmacopeial plant material has never been performed. Moreover, the number of biological and pharmacological investigations proving the usefulness of this plant material in recommended traditional uses is surprisingly small. Objective Phytochemical profiling of ash leaf samples from different commercial and natural sources and the determination of the in vitro effects on inflammatory mediators in a model of human neutrophils. Methods Ash leaf samples were characterised by total hydroxycinnamic acid content and by high‐performance thin layer chromatography (HPTLC), UHPLC‐DAD‐ESI‐MS/MS methods. The effects of leaf infusions on reactive oxygen species (ROS), tumor necrosis factor (TNF‐α), interleukin 8 (IL‐8), interleukin 1β (IL‐1β), and monocyte chemoattractant protein 1 (MCP‐1) production by neutrophils were measured using luminol‐dependent chemiluminescence and enzyme‐linked immunosorbent assay (ELISA). Results In ash leaf samples 64 compounds were identified or partly identified together with four unknown compounds. The major compounds detected belong to different structural groups, including phenolic acid derivatives, phenylethanoids, flavonoids, iridoids, secoiridoids and lignans. The major compounds detected in ash samples were chlorogenic acid, quercetin‐3‐O‐rutinoside, verbascoside, oleuropein and ligstroside. However, one sample contained coumarin derivatives. This finding suggested adulteration with other Fraxinus species and/or plant parts. All infusions were able to inhibit ROS, cytokine and chemokine production. Conclusions The performed phytochemical and biological analyses contribute to the knowledge about this pharmacopeial plant material and supports its traditional use to treat minor inflammatory complaints.

“…The extraction of anthocyanins and flavonols were performed as previously described (Wan et al, 2018). About 0.2 g powder [fresh weight (FW)] of all samples was used for pigment extraction with 1.8 mL methanol: water: methane acid: trifluoroacetic acid (70:27:2:1, v/v/v/v) using ultrasonication at 20°C for 30 min.…”

Rose is one of the most valuable ornamental crops worldwide. In this study, the composition of hydrophilic and lipophilic pigments in petals of six rose cultivars at seven developing stages was investigated using high performance liquid chromatography and mass spectrometry. Four anthocyanins, 20 flavonols, and 10 carotenoids were detected in petals of tested cultivars. Major individual anthocyanin, flavonol, and carotenoid were cyanidin/pelargonidin 3,5-diglucoside, kaempferol 3- O -rhamnoside, and (9 Z )-violaxanthin, respectively. Significant differences were observed in pigments content in petals of different rose cultivars. The yellow petals of YI and GC exhibited no to very small amounts of anthocyanins, moderate amount of total flavonols, and highest content of total carotenoids. Similarly, pink petals of PF, WQ, and YX showed average concentration of total anthocyanins, highest concentration of total flavonols, and small amount of carotenoids. Further, orange petals of CH showed highest content of total anthocyanins, lowest content of total flavonols, and average content of total carotenoids. Correlation analysis demonstrated that there were many pigments influencing petal colors. Moreover, multiple linear regression indicated that pelargonidin 3,5-diglucoside, total anthocyanins and (9 Z )-violaxanthin were the major factors. In addition, this study showed that orange cultivar CH, pink cultivar PF and yellow cultivar YI can have great potential as a natural source for the extraction of pelargonidin 3- O -glucoside, kaempferol 3- O -rhamnoside, and (9 Z )-violaxanthin, respectively. These investigations would contribute toward understanding the mechanism on the development of flower colors and provide a theoretical basis for the breeding of rose with specific color.

BACKGROUNDThe fruits of the genus Rosa, commonly known as rosehips, have attracted significant attention owing to their rich content of various bioactive compounds. However, their utility is generally secondary to the ornamental appeal of their flowers. This study aimed to explore the quality differences among tea‐scented rosehips found in Yunnan, China, including those of Rosa odorata var. odorata (RO), Rosa odorata var. gigantea (RG), and Rosa yangii (RY). Morphological characteristics, chemical composition, and antioxidant activity of their fruits were evaluated.RESULTSThe study revealed significant variability in composition and biological activities based on fruit color. RO exhibited the highest levels of polyphenols, flavonoids, anthocyanins, carotenoids, and vitamin C, with the strongest antioxidant activity (10.99 μmol Trolox·g−1), followed by RG (7.91 μmol Trolox·g−1) and RY (6.52 μmol Trolox·g−1). This supports RO's potential as a functional food source. Untargeted metabolomics identified and quantified 502 metabolites, with flavonoids (171) and phenolic acids (147) as the main metabolites. The differential metabolites among the fruits are primarily enriched for flavonoid biosynthesis and phenylpropanoid biosynthesis pathways. Insights into color formation supported the role of anthocyanins, flavones, and flavonols in fruit color variation.CONCLUSIONTea‐scented rosehips offer vibrant colors and high nutritional value with potent biological activities. Rosa odorata var. odorata stands out as a functional food source owing to its rich bioactive compounds. These findings lay the groundwork for utilizing rosehips in functional foods, health supplements, and food additives, emphasizing the practical and beneficial applications of Rosa spp. independent of their ornamental value. © 2023 Society of Chemical Industry.
