“…In addition, the seed contains flavonoids, mucilage, coumarins, sulfur glycosides, triterpenes, sterols, natural antioxidants, imidazole alkaloids, glucosinolates, and tannins [1,20,29]. Garden cress is widely used in folk medicine for the treatment of respiratory diseases, liver disease, antimicrobial, anti-inflammation, jaundice, anti-diabetic, gastrointestinal disorders, menstrual problems, bone fractures, osteoarthritis, spleen diseases, muscular pain, and kidney problems [8,14,17]. El Ghazaliet al [8] reported that in Sudan, garden cress had been used for wound treatment and gastrointestinal disorders.…”

In the present study, a field experiment was conducted for two consecutive seasons (2016/2017 and 2017/2018). The effects of organic and inorganic fertilization on growth, seed yield, seed fixed oil yield, and fatty acid profile of garden cress (Lepidium sativum L.) were investigated under conditions of Khartoum State, Sudan. In each season, the experiment was laid out in a randomized complete block design with four replications. Four fertilizer treatments were used; these were chicken manure at a rate of 11.9 tonha −1 , NPK (15:15:15) at two rates, 476 kgha −1 (NPK1), 952 kgha −1 (NPK2) as well as the control. Morphometric parameters, yield components, seed fixed oil content (%), seed fixed oil yield (tonha −1), and fatty acids profile were measured. Means were separated using the least significant difference at p ≤ 0.05 and at p ≤ 0.01. The difference between chicken manure, NPK1, and NPK2 was not significant (p ≤ 0.05) in both seasons, for plant height and 1000-seed weight. However, it was significant (p > 0.05) with chicken manure in both seasons for the number of leaves (831.7, 684), the number of branches (144.8, 128.5), fresh weight (57.74, 61.25), and dry weight (6, 7.7). The NPK2 treatment significantly (p ≤ 0.05) increased the number of capsules (339.5, 308 tonha −1), seed yield (5.51, 4.8 tonha −1), seed fixed oil content (25.65%, 25%), and seed fixed oil yield (1.4, 1.1 tonha 1) compared to the control in both seasons. The oil profile was affected by all fertilizer treatments. Acoordingly, it can be concluded that using fertilizer is recommended for improvement of growth, seed yield, and oil yield, and quality of L. sativum.

“…Petroselinic acid (C18:1n12c; an isomer of oleic acid) is the major component of the lipid constituent of Apiaceae family seeds [ 27 , 28 ]. In a previous study [ 27 ] of dill ( Anethum graveolens ) seeds, 87.2% of total fatty acids were composed of petroselinic acid. Similarly, in celery ( Apium graveolens ), coriander seeds ( Coriandrum sativum ), and fennel seeds ( Foeniculum vulgare ), petroselinic acid was recorded as being 56.1%, 72.8%, and 31.32% of total fatty acids.…”

Spices and herbs are well-known for being rich in healthy bioactive metabolites. In recent years, interest in the fatty acid composition of different foods has greatly increased. Thus, the present study was designed to characterize the fatty acid composition of 34 widely used spices and herbs. Utilizing gas chromatography (GC) flame ionization detection (FID) and GC mass spectrometry (MS), we identified and quantified 18 fatty acids. This showed a significant variation among the studied spices and herbs. In general, oleic and linoleic acid dominate in seed spices, whereas palmitic, stearic, oleic, linoleic, and α-linolenic acids are the major constituents of herbs. Among the studied spices and herbs, the ratio of n−6/n−3 polyunsaturated fatty acids (PUFAs) was recorded to be in the range of 0.36 (oregano) to 85.99 (cumin), whereas the ratio of PUFAs/saturated fatty acids (SFAs) ranged from 0.17 (nutmeg) to 4.90 (cumin). Cumin, coriander, fennel, and dill seeds represent the healthiest fatty acid profile, based upon fat quality indices such as the ratio of hypocholesterolemic/hypercholesterolemic (h/H) fatty acids, the atherogenic index (AI), and the thrombogenic index (TI). All these seed spices belong to the Apiaceae family of plants, which are an exceptionally rich source of monounsaturated fatty acids (MUFAs) in the form of petroselinic acid (C18:1n12), with a very small amount of SFAs.

“…The extracts possessed antioxidant activity due to the presence of gallic acid, mangiferin, and caffeic acid. This can be explained by the fact that phenolic compounds are potent antioxidants [ 50 , 64 , 65 ] due to their high redox potential allowing them to become hydrogen donors and singlet oxygen quenchers [ 66 ]. The established antioxidant activity of the extracts was correlated with the content of the identified compounds.…”

Qualitative and Quantitative Analysis of Ukrainian Iris Species: A Fresh Look on Their Antioxidant Content and Biological Activities

et al. 2020

The major groups of antioxidant compounds (isoflavonoids, xanthones, hydroxycinnamic acids) in the rhizome methanol extracts of four Ukrainian Iris sp. (Iris pallida, Iris hungarica, Iris sibirica, and Iris variegata) were qualitatively and quantitatively analyzed using HPLC-DAD and UPLC-MS/MS. Gallic acid, caffeic acid, mangiferin, tectoridin, irigenin, iristectorigenin B, irisolidone, 5,6-dihydroxy-7,8,3′,5′-tetramethoxyisoflavone, irisolidone-7-O-β-d-glucopyranoside, germanaism B, and nigricin were recognized by comparing their UV/MS spectra, chromatographic retention time (tR) with those of standard reference compounds. I. hungarica and I. variegata showed the highest total amount of phenolic compounds. Germanaism B was the most abundant component in the rhizomes of I. variegata (7.089 ± 0.032 mg/g) and I. hungarica (6.285 ± 0.030 mg/g). The compound analyses showed good calibration curve linearity (r2 > 0.999) and low detection and quantifications limit. These results validated the method for its use in the simultaneous quantitative evaluation of phenolic compounds in the studied Iris sp. I. hungarica and I. variegata rhizomes exhibited antioxidant activity, as demonstrated by the HPLC-ABTS system and NRF2 expression assay and anti-inflammatory activity on respiratory burst in human neutrophils. Moreover, the extracts showed anti-allergic and cytotoxic effects against cancer cells. Anti-coronavirus 229E and lipid formation activities were also evaluated. In summary, potent antioxidant marker compounds were identified in the examined Iris sp.
