Detailed Phytochemical Composition, Cyto-/Hepatotoxicity, and Antioxidant/Anti-Inflammatory Profile of Moroccan Spices: A Study on Coriander, Caraway, and Mystical Cumin. Molecules 2024; 29:3485. [PMID: 39124890 PMCID: PMC11313914 DOI: 10.3390/molecules29153485] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2024] [Revised: 07/19/2024] [Accepted: 07/23/2024] [Indexed: 08/12/2024] Open
Abstract
Coriander, caraway, and mystical cumin are famous for their aromatic properties and widely used in Moroccan cuisine. The nutritional/phytochemical composition of their seeds (used for food flavoring and preservation) were compared. Their antioxidant, anti-inflammatory, cytotoxic and hepatotoxic effects were also explored. The fat content was similar among the samples (13%), with monounsaturated fatty acids being predominant. The coriander and mystical cumin seeds were extremely rich in C18:1n9c (81 and 85%, respectively) while, in the caraway, C18:1n12 (25%) was found together with C18:1n9c (32%). The caraway seeds also presented a higher proportion of C18:2n6c (34%) than the other seeds (13 and 8%, correspondingly). γ-Tocotrienol was the major vitamin E form in all the samples. The caraway seeds contained double the amount of protein (~18%) compared to the other seeds (~8%) but, qualitatively, the amino acid profiles among all seeds were similar. The seeds were also rich in dietary fiber (40-53%); however, differences were found in their fiber profiles. Caraway showed the highest antioxidant profile and anti-inflammatory activity and an LC-DAD-ESI/MSn analysis revealed great differences in the phenolic profiles of the samples. Cytotoxicity (NCI-H460, AGS, MCF-7, and CaCo2) and hepatotoxicity (RAW 264.7) were not observed. In sum, besides their flavoring/preservation properties, these seeds are also relevant source of bioactive compounds with health-promoting activities.

Antioxidant and anti-inflammatory potentials of Ammodaucus leucotrichus Coss. & Durieu seeds' extracts: In vitro and in vivo studies. JOURNAL OF ETHNOPHARMACOLOGY 2024; 326:117964. [PMID: 38401663 DOI: 10.1016/j.jep.2024.117964] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/01/2024] [Revised: 02/19/2024] [Accepted: 02/20/2024] [Indexed: 02/26/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ammodaucus leucotrichus Coss. & Durieu (Apiaceae) is traditionally used in southern Algeria as a remedy against a wide range of disease due to its health-promoting properties. AIM OF THE STUDY To investigate anti-oxidant and anti-inflammatory potentials of plant methanolic extract and its fractions in vitro and in vivo. MATERIALS AND METHODS Anti-radical activity was assessed in vitro using ABTS•+, superoxide anion (O2•-) and nitric oxide radical (•NO). Lipid peroxidation inhibition was also investigated in the linoleic acid system. Enzyme inhibition assay was performed against α-amylase and α-glucosidase. The anti-inflammatory effect of extracts was screened in vitro through thermal induction of human serum albumin, and in vivo on a skin acute inflammation model induced by λ-carrageenan paw injection, xylene and croton oil topical application. Analgesic effect was evaluated by acetic acid-induced writhing test. RESULTS The highest contents of polyphenols and flavonoids was recorded by the crude extract (77.14 ± 0.01 μg GAE/mg E and 19.59 ± 0.08 μg QE/mg E, respectively). Among the extracts, ethyl acetate extract showed a promising anti-radical activity of ABTS•+, O2•- and •NO, in addition to a remarkable inhibition activity of the tested enzymes. Meanwhile, all extracts effectively protected linoleic acid against lipid peroxidation and human serum albumin structure in thermal condition even at low concentration (0.31 mg/ml). Oral administration of 200 mg/kg of crude extract successfully inhibited acetic acid induced nociception and reduced edema formation induced by xylene and carrageenan. However, a dose-dependent manner was observed to decrease ear edema by a microscopic examination in croton oil induced acute inflammation. Nitrite and malondialdehyde levels together with catalase activity were modulated in the presence of plant-derived bioactive compounds. CONCLUSIONS This study showed that Ammodaucus leucotrichus is potentially rich source of anti-oxidant and anti-inflammatory bioactive compounds.

Perillaldehyde is a new ferroptosis inducer with a relevant clinical potential for acute myeloid leukemia therapy. Biomed Pharmacother 2022; 154:113662.

Abstract
Ferroptosis induction is an emerging strategy to treat cancer and contrast the tricky issue of chemoresistance, which can arise towards apoptosis. This work elucidates the anticancer mechanisms evoked by perillaldehyde, a monoterpenoid isolated from Ammodaucus leucotrichus Coss. & Dur. We investigated and characterized its antileukemic potential in vitro, disclosing its ability to trigger ferroptosis. Specifically, perillaldehyde induced lipid peroxidation, decreased glutathione peroxidase 4 protein expression, and depleted intracellular glutathione on HL-60 promyelocytic leukemia cells. Besides, it stimulated the active secretion of ATP, one of the most crucial events in the induction of efficient anticancer response, prompting further studies to disclose its possible nature as an immunogenic cell death inducer. To preliminarily assess the clinical relevance of perillaldehyde, we tested its ability to induce cell death on patient-derived acute myeloid leukemia biopsies, recording a similar mechanism of action and potency compared to HL-60 cells. To round the study off, we tested its selectivity towards tumor cells and disclosed lower toxicity on normal cells compared to both HL-60 and acute myeloid leukemia biopsies. Altogether, these data depict a favorable risk-benefit profile for perillaldehyde and reveal its peculiar antileukemic potential, which qualifies this natural product to proceed further through the drug development pipeline.

Abstract
The ethnobotany of the Sahrawi people considers various species of plants and crude drugs as food, cooking spices and traditional health remedies. From among these, the fruits of Ammodaucus leucotrichus Coss. & Dur. (Apiaceae), known as Saharan cumin, were chosen for our research. The present paper reports a proximate composition and mineral element analysis of various samples of A. leucotrichus fruits, collected during the balsamic period (full fruiting) from plants grown in Bir Lehlu (Western Sahara) and purchased in a local market (Tindouf). These analyses pointed out interesting nutritional values of the crude drug. Decoction and alcoholic extract, analyzed by HPLC-DAD, evidenced ammolactone-A and R-perillaldehyde as the two main isolated constituents, particularly in the ethanolic extracts (ammolactone-A, market sample: 51.71 ± 0.39 mg/g dry extract; wild sample: 111.60 ± 1.80 mg/g dry extract; R-perillaldehyde, market sample: 145.95 ± 0.35 mg/g dry extract; wild sample: 221.40 ± 0.30 mg/g dry extract). The essential oils, obtained through hydrodistillation, were characterized by GC-MS and evidenced R-perillaldehyde (market sample: 53.21 ± 1.52%; wild sample: 74.01 ± 1.75%) and limonene (market sample: 35.15 ± 1.68%; wild sample: 19.90 ± 1.86%) as the most abundant compounds. The R configuration of perillaldehyde was ascertained and a complete description of the 1H and 13C NMR spectra of ammolactone-A was performed.

Abstract
Ammodaucus leucotrichus Cosson and Durieu, known as Sahara cumin, is a plant belonging to the Apiaceae family with a very strong smell of anise growing in the maritime sands in the countries of North Africa. The present work aims to study the polyphenolic profile of its seeds hydroalcoholic extract along with the determination of the antioxidant and antiglycation properties. The phytochemical screening revealed the presence of 16 compounds, out of which 15 have been detected in this extract for the first time. Luteolin‐glucoside turned out to be the most abundant one (281.32 ± 0.34 mg/kg), followed by apigenin‐hexoside (235.06 ± 0.29 mg/kg) and luteolin (202.41 ± 0.40 mg/kg). In terms of antioxidant activity, a half‐maximal inhibitory concentration value as high as 0.39 ± 0.003 mg AAE/ml (w/v) was attained. Further, the antiglycation activity was determined to yield interesting results: at a concentration of 1.5 mg/ml, the extract showed an antiglycation activity (%I) of 61.86 compared to metformin as a positive control (%I = 84.01); on the other hand, increasing the concentration to 10 mg/ml, the inhibition activity switched to advanced glycation end products formation activation (%I = 41.71).

[PMID: 35265127 PMCID: PMC8898872 DOI: 10.1155/2022/8744964] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Revised: 08/21/2021] [Accepted: 01/20/2022] [Indexed: 11/27/2022] Open
Abstract
Succinic acid (SA) and oleic acid (OA) are the primary hypoglycaemic agents in Desmodium canum, a plant traditionally employed for its potential health benefits. The synergy of the two organic acids exhibits potency in retarding blood glucose levels (BGL) in euglycaemic Sprague Dawley (S-D) rats following a single-dose administration. A cocktail of the two compounds is being investigated for its antidiabetic properties in fructose-fed streptozotocin (STZ)-induced diabetic rats. Eighteen type 2 diabetic S-D rats were divided into 3 groups and treated for 28 d with either the cocktail (OA + SA, 800 mg/kg body weight [BW]), glibenclamide (10 mg/kg BW), or vehicle (10% polysorbate 20). Another 12 S-D rats served as euglycaemic animals and were divided into two groups, fed either the cocktail (OA + SA, 800 mg/kg BW) or vehicle. Changes in BW, blood pressure (BP), BGL, water and food consumption, serum insulin, serum glucagon and insulin resistance (IR) were monitored. Treatment with the cocktail showed no change in euglycaemic animals; however, there was a significant reduction in the BGL of diabetic treated animals when compared with diabetic control (14.48 ± 1.92 vs. 25.56 ± 1.38 mM; p=0.012). Quantitative insulin sensitivity check index (QUICKI) and glucose/insulin (G/I) scores for IR indicated an improvement in insulin response in the diabetic treated animals. Additionally, there was a noticeable reduction in food and water consumption when compared with diabetic control animals, which was accompanied by a reduction in weight. Overall, the cocktail elicited antidiabetic properties and may serve an important therapeutic role as a nutritional supplement in type 2 diabetics.
