“…Quercetin-O-hexauronide and apigenin-O-hexosyl-malonate were differential markers enriched in unroasted fennel and unroasted cumin specimens, respectively suggesting for the degradation of avonoid glycosides in agreement with our previous report in Ceratonia siliqua pod. 10 Likewise, the S-plot also revealed for a richer fatty acids prole viz., oleic acid (anise), hydroxyoctadecadienoic acid (anise & fennel), linoleic acid (fennel) and hydroxyoctadecenoic acid (cumin) in unroasted samples indicating that roasting catalyzes lipid degradation. Additionally, Maillard type degradation reaction is a plausible explanation for the detection of furan peak (difuranyl-dimethyl-undecatrien-ol) as most distinctive marker in roasted cumin fruit.…”

“…9 Furthermore, it has been also utilized for assessing changes incurring as a results of food processing as typical in many of its products. 10 A metabolomics study revealed that roasting led to increased levels of proline derivatives viz., betonicine, N-methylproline and stachydrine in peanuts suggestive for changes in their amino acid pattern. 11 We have previously reported a metabolomics study 12 assessing umbelliferous fruits' aroma proles using headspace solid phase microextraction gas chromatography mass spectrometry (SPME-GC/MS) targeting its aroma compounds.…”

“…The biological importance of carob leaves as a potential antifeedant was recently revealed [8]. The complexity of carob metabolome in combination with origin, ripening and roasting was studied using hyphenated state-of-the-art liquid and gas mass spectrometric systems [9]. The positive biological effects of carobs in the gastrointestinal tract, consumed either as water diluted food [10] or as an alcoholic drink [11], is still triggering the interest of researchers.…”

Carobs unique compositional and biological synthesis enables their characterization as functional foods. In the present study, 76 samples derived from fruit and seeds of carobs, with origin from the countries of the Mediterranean region (Cyprus, Greece, Italy, Spain, Turkey, Jordan and Palestine) were analyzed for their nutritional composition, in order to identify potential markers for their provenance and address the carobs' authenticity issue. Moisture, ash, fat, proteins, sugars (fructose, glucose, sucrose), dietary fibers and minerals (Ca, K, Mg, Na, P, Cu, Fe, Mn, Zn) were estimated following official methods. Due to the large number of data (76 samples × 17 parameters × 7 countries), chemometric techniques were employed to process them and extract conclusions. The samples of different geographical origin were discriminated with 79% success in total. The carobs from Cyprus, Italy and Spain were correctly classified without error. The main discriminators were found to be the dietary fibers, the carbohydrates and Cu, Zn and Mn, which emphasize their specific nutritional added value to the product and the country of origin impact. The results suggest that the proposed analytical approach is a powerful tool that enables the discrimination of carobs based on their country of origin. This research contributes to authenticity of carobs, adding value to local products.Metabolites 2020, 10, 62 2 of 11 demands. Carob flesh is rich in minerals, dietary fibers, sugars, polyphenols, D-pinitol and with low fat content, whereas the seed is abundant with locust bean gum (E 410), a natural hydrocolloid widely used in the food industry [3][4][5][6][7]. The chemical composition of carob flesh is presented in Table 1; however, these values are affected by various practices and factors (e.g., farming, genotyping, climate, soil, etc.). Environmentally speaking, the wide presence of carobs in the Mediterranean region can be attributed to combat the negative effects of climate change. The biological importance of carob leaves as a potential antifeedant was recently revealed [8]. The complexity of carob metabolome in combination with origin, ripening and roasting was studied using hyphenated state-of-the-art liquid and gas mass spectrometric systems [9]. The positive biological effects of carobs in the gastrointestinal tract, consumed either as water diluted food [10] or as an alcoholic drink [11], is still triggering the interest of researchers. Last but not least, is the carob's unique sensorial characteristics, as both the fruit and the carob-products, are associated with a strong and persisting unique aroma [12].

Lepidium sativum seeds are used traditionally to accelerate healing of bone fracture in addition to its culinary uses. This study aimed to characterize the osteoprotective effect of L. sativum in an ovariectomized rat model at two dose levels (50 and 100 mg/kg) using 17β-estradiol as a positive reference standard. Moreover, a complete metabolite profile of L. sativum via UHPLC/PDA/ESI–MS, as well as headspace solid-phase microextraction (SPME)-GC/MS is presented. Results revealed that L. sativum extract exhibited significant anti-osteoporotic actions as evidenced by mitigating the decrease in relative bone weight concurrent with improved longitudinal and perpendicular femur compression strength. Further, the extract enhanced the serum bone formation biomarkers lactate dehydrogenase (LDH) activity and osteocalcin levels. The extract also inhibited exhaustion of superoxide dismutase (SOD) as well as glutathione peroxidase (GPx) activities and accumulation of lipid peroxides in bone tissues. This is in addition to ameliorating the rise in the markers of bone resorption carboxyterminal telopeptide, type I (CTXI) and tartrate-resistant acid phosphatase (TRAP) and modulating receptor activator of nuclear factor kappa-Β ligand (RANKL)/ osteoprotegerin (OPG) expression. Metabolite characterization suggests that glucosinolates, lignans, coumarins, phenolic acids, and alkaloids mediate these anti-osteoporotic effects in a synergistic manner.
