Untargeted metabolite profiling: A comprehensive study using data analysis workflow in Salvia L. species (Lamiaceae)

Metabolomic Profiling and DNA‐Fingerprinting of Newly Recorded White‐Flowered Populations of Salvia lanigera Poir. in Egypt

“…They were tentatively identified as eriodictyol 7-O-glucoside (21, m/z 449.10893) and naringenin 7-O-glucoside (27, m/z 433.11402), confirmed by product ions m/z 287 and m/z 271, respectively, after the loss of the glucoside moiety. These structures were reported before from other Salvia species [26] and several mint taxa. [29,36]…”

“…Other hydroxycinnamic acid derivatives were observed in cluster A or as self-looping nodes and represented as caffeic acid (8, m/z 179.03498) and its byproducts caffeoyl tartaric acid (caftaric acid) (6, m/z 311.04163) and caffeoyl malic acid (14, m/ z 295.04611), together with coumaroyl malic acid (16, m/z 279.05148), which were distributed in both populations (Table 3, Figure 2). It is worth noting that ferulic, caffeic, and coumaric acids, along with their glycosidic and malate derivatives, have been reported previously in some Salvia species, [25,26] but the detected malate substitutions are reported for the first time in S. lanigera now.…”

“…In several studies, phenolic acids were detected in various Salvia species based on different chromatographic analysis. [25][26][27] The negative MN manages to gather the related phenolic acids and their derivatives together as certain nodes of clusters A, B, and C, as well as one self-looping node encompassing 18 tentatively identified compounds (Table 3, Figure 2). Three hydroxybenzoic acids were scattered in cluster A and distributed in both violet-and white-flowered populations.…”
