Abstract
This study is the first chemical investigation of Ferula mervynii M. Sağıroğlu & H. Duman, an endemic species to Eastern Anatolia. The isolations of nine compounds including six previously undescribed sesquiterpene esters, 8-trans-cinnamoyltovarol (1), 8-trans-cinnamoylantakyatriol (3), 6-acetyl-8-trans-cinnamoyl-3-epi-antakyatriol (5), 6-acetyl-8-trans-cinnamoylshiromodiol (6), 6-acetyl-8-trans-cinnamoylfermedurone (7), and 6-acetyl-8-trans-cinnamoyl-(1S),2-epoxyfermedurone (8), were described along with three known sesquiterpene esters, 6-acetyl-8-benzoyltovarol (2), 6-acetyl-8-trans-cinnamoylantakyatriol (4), and ferutinin (9). The structures of novel compounds were elucidated through extensive spectroscopic analyses and quantum chemistry calculations. The putative biosynthetic pathways for compounds 7 and 8 were discussed. The extracts and isolated compounds were tested for cytotoxic activity against the COLO 205, K-562, MCF-7 cancer cell lines, and Human Umbilical Vein Endothelial Cell (HUVEC) lines using MTT assay. Compound 4 showed the highest activity against the MCF-7 cell lines with an IC50 value of 16.74±0.21 μM.

Phytochemicals, Antioxidant and Antimicrobial Potentials and LC-MS Analysis of Centaurea parviflora Desf. Extracts. Molecules 2023; 28:molecules28052263. [PMID: 36903521 PMCID: PMC10005273 DOI: 10.3390/molecules28052263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Revised: 02/16/2023] [Accepted: 02/24/2023] [Indexed: 03/06/2023] Open
Abstract
Centaurea parviflora (C. parviflora), belonging to the family Asteraceae, is an Algerian medicinal plant used in folk medicine to treat different diseases related to hyperglycemic and inflammatory disorders, as well as in food. The present study aimed to assess the total phenolic content, in vitro antioxidant and antimicrobial activity and phytochemical profile of the extracts of C. parviflora. The extraction of phenolic compounds from aerial parts was conducted using solvents of increasing polarity starting from methanol, resulting in crude extract (CE), to chloroform extract (CHE), ethyl acetate extract (EAE) and butanol extract (BUE). The total phenolic, flavonoid and flavonol contents of the extracts were determined using the Folin-Ciocalteu and AlCl3 methods, respectively. The antioxidant activity was measured with seven methods: 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, galvinoxyl free-radical-scavenging test, 2,2'-Azino-Bis(3-Ethylbenzothiazoline-6-Sulfonic Acid) (ABTS) assay, cupric reducing antioxidant capacity (CUPRAC), reducing power, Fe+2-phenanthroline reduction assay and superoxide-scavenging test. The disc-diffusion method aimed at testing the sensitivity of bacterial strains toward our extracts. A qualitative analysis with thin-layer chromatography of the methanolic extract was performed. Moreover, HPLC-DAD-MS was used to establish the phytochemical profile of the BUE. The BUE was found to contain high amounts of total phenolics (175.27 ± 2.79 µg GAE/mg E), flavonoids (59.89 ± 0.91 µg QE/mg E) and flavonols (47.30 ± 0.51 µg RE/mg E). Using TLC, different components such as flavonoids and polyphenols were noted. The highest radical-scavenging ability was recorded for the BUE against DPPH (IC50 = 59.38 ± 0.72 µg/mL), galvinoxyl (IC50 = 36.25 ± 0.42 µg/mL), ABTS (IC50 = 49.52 ± 1.54 µg/mL) and superoxide (IC50 = 13.61 ± 0.38 µg/mL). The BUE had the best reducing power according to the CUPRAC (A0.5 = 71.80 ± 1.22 μg/mL), phenanthroline test (A0.5 = 20.29 ± 1.16 μg/mL) and FRAP (A0.5 = 119.17 ± 0.29 μg/mL). The LC-MS analysis of BUE allowed us to identify eight compounds including six phenolic acids and two flavonoids: quinic acid, five chlorogenic acid derivatives, rutin and quercetin 3-o-glucoside. This preliminary investigation revealed that the extracts of C. parviflora have a good biopharmaceutical activity. The BUE possesses an interesting potential for pharmaceutical/nutraceutical applications.

Abstract
Dry MeOH extract of Ferula heuffelii (Apiaceae) underground parts was tested for spasmolytic, gastroprotective and antioxidant activities. HPLC analysis revealed that chlorogenic acid (CGA; 34.6 mg/g) was its main constituent. Extract in vitro exhibited notable total antioxidant activity (FRAP value=1.0 μmol Fe2+ /mg), and scavenging of DPPH (SC50 =62.5 μg/ml) and • OH radicals (49.5 % at 20 μg/ml in 2-deoxyribose assay). In vitro on isolated rat ileum, extract exhibited significant spasmolytic activity, i. e., it showed 124.6 % of maximal atropine effect on spontaneous contractions (at 100 μg/ml), and reduced spasmogenic effect of KCl (80 mm) to 44.4 % (at 60 μg/ml) and of highest applied concentration of ACh to 26.3 % (at 120 μg/ml). In parallel experiments, spasmolytic effect of CGA was also demonstrated. In acute EtOH-induced gastric ulceration model in rats, extract (100 mg/kg p.o.) showed significant gastroprotective effect (gastric damage score 0.50), similar to ranitidine (20 mg/kg p.o.). Obtained results showed that tested F. heuffelii polar extract represents new herbal preparation with potential use against some gastrointestinal complaints.

IRANIAN JOURNAL OF BASIC MEDICAL SCIENCES 2021; 24:1613-1623. [PMID: 35432802 PMCID: PMC8976906 DOI: 10.22038/ijbms.2021.59473.13204] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 11/07/2021] [Indexed: 12/16/2022]
Abstract
Ferula is a genus of the family Apiaceae and it includes around 170 species of flowering plants mostly native to the Mediterranean region and eastern to central Asia. In Iran, Ferula spp. are widely used in cuisine and traditional medicine. This review discusses the anti-inflammatory, anti-oxidant, and immunomodulatory activities of different species of Ferula. To prepare the present review, Scopus, Google Scholar, PubMed, and Web of Science scientific databases were searched to retrieve relevant articles published from 1985 until December 2020. Based on our literature review, Ferula plants and their derivatives decrease the levels of inflammatory mediators and exert anti-apoptotic effects. Under oxidative stress conditions, these plants and their constituents were shown to decrease oxidative markers such as malondialdehyde, reactive oxygen species, and nitric oxide but increase superoxide dismutase, glutathione peroxidase, catalase activity, and glutathione level. Ferula plants and their constituents also showed immunomodulatory effects by affecting various cytokines. Besides, in vivo and in vitro studies showed hypotensive, neuroprotective, memory-enhancing, anti-oxidant, hepatoprotective, antimicrobial, anticarcinogenic, anticytotoxic, antiobesity, and anthelmintic effects for various species of Ferula and their constituents. These plants also showed a healing effect on gynecological issues such as miscarriage, unusual pain, difficult menstruation, and leukorrhea. All these beneficial effects could have resulted from the anti-inflammatory, anti-oxidant, and immunomodulatory effects of these plants and their constituents. Based on the available literature, members of the genus Ferula can be regarded as potential therapeutics against inflammatory conditions, oxidative stress, and immune dysregulation.

Abstract
RATIONALE Flavonol glycosides containing the glycosylation patterns 3,4'-di-O and 4',7-di-O are rare in nature and they have not yet been studied in detail by electrospray ionization mass spectrometry (ESI-MS(+/-), in contrast to the flavonol glycosides containing the glycosylation pattern 3,7-di-O. METHOD The leaves from Prunus domestica L. subsp. syriaca were extracted with pure methanol or, in order to perform hydrolysis and extraction simultaneously, with a 5% methanolic solution of hydrochloric acid. The high-performance liquid chromatography (HPLC)/ESI-MS(+/-) analyses were performed using a Waters model 2690 HPLC pump and a Waters/Micromass ZQ2000 mass spectrometer. RESULTS Three kinds of kaempferol di-O-glycosides have been identified, namely kaempferol-3-O-hexoside-7-O-rhamnosides, kaempferol-3-O-pentoside-4'-O-rhamnosides and kaempferol 4',7-di-O-rhamnoside. The identification was performed on the basis of the abundances of the respective Y-type product ions. CONCLUSIONS The abundances of [Yn 0 - H]-· , Yn 0 - and Yn 0 + product ions were of crucial importance for the determination of glycosylation patterns. The obtained results can be useful for HPLC/ESI-MS identification of rare flavonol-di-O-glycosides.

Abstract
The aim of the present study is to evaluate the total phenolic contents, antioxidant and anti-proliferative activities of the n-BuOH extract of Centaurea maroccana (BECM). The total phenolic and flavonoid of the butanolic extract of the plant were assessed by using Folin-Ciocalteau and aluminium chloride colorimetric assays, respectively, and the quantitative estimation of total flavonoids and phenols revealed the richness of the extract in these compounds. Antioxidant activity was evaluated using standard lab colorimetric methods, while the anti-proliferative activity was evaluated using sulforhodamine B (SRB) assay against C6 (Rattus norvegicus brain glioma) and HT29 (Homo sapiens colorectal adenocarcinoma) cell lines. The n-butanolic extract of Centaurea maroccana showed a strong antioxidant activity through DPPH, ABTS•+, DMSO alkalin, Reducing power, β-Carotene-linoleic acid and CUPRAC assays. Furthermore, the anti-proliferative activity against C6 and HT29 of Centaurea maroccana exhibited a high effect by the decrease in viability of both cancer cell lines. Our results suggest a possible use of Centaurea maroccana as a source of natural antioxidant and chemo-preventive agents against cancer.

Abstract
Anthriscus cerefolium (L.) Hoffm. is a plant traditionally used around the globe since antiquity. Although widely used in many traditional medicines in different cultures, from the scientific point of view it is poorly investigated. Glioblastoma, a tumor type with poor prognosis, is the most common and lethal brain tumor in adults. Current therapeutic strategies for glioblastoma include surgery, radiation and chemotherapy. On the other hand, it has been revealed that patients with cancers are highly susceptible to microbial infections due to the invasive nature of cancer treatment approaches. This study was designed to investigate the chemical profile of herba Anthriscii cerefoli methanolic extract by applying UHPLC-LTQ OrbiTrap MS4 analysis and to analyze its anti-glioblastoma and antimicrobial activities. This study revealed that methanolic extract of herba Anthrisc cerefolii contained phenolic acids and flavonoids, with 32 compounds being identified. Anti-glioblastoma activity was investigated in vitro using A172 glioblastoma cell line. The cytotoxic effects of the extract on A172 cells were compared to the same effect on primary human gingival fibroblast (HGF-1) cells. Decreased rate of proliferation and changes in cell morphology were detected upon treatment of A172 cells with the extract. The antimicrobial activity of extract was tested against Staphylococcus aureus and Candida species. The extract was active against the tested bacterium and yeasts, inhibiting free floating cells and microbial biofilms. This study is the first one to provide a detailed description of the chemical profile of A. cerefolium extract dealing with scientific insights into its anti-glioblastoma and antimicrobial activities.

Abstract
The nanoencapsulation of essential oils enhances their applicability in several areas, such as pharmaceuticals and food biopreservation. This study focuses on the encapsulation of Saccocalyx satureioides Coss. et Durieu essential oil into nanoemulsions by high-pressure homogenization (HPH) and its effect on the volatile constituents and the antioxidant and anticancer activities of the essential oil. The analysis of hydrodistilled (HD) S. satureioides essential oil using gas chromatography-mass spectrometry revealed a total of 28 constituents, representing 99.80%, while only 13 constituents were identified in nanoemulsions, representing 98.65% of the total volatile material. The use of HPH led to qualitative and quantitative differences between the volatile profiles of the HD and the nanoemulsion of S. satureioides essential oil. Whereas borneol, α-terpineol, and thymol were the predominant constituents in the HD oil, carvacrol, thymol, and γ-terpinene were the major constituents in the nanoemulsion. The antioxidant activity of the S. satureioides essential oil nanoemulsion displayed was lower as compared to that of HD oil using DPPH free radical-scavenging, CUPRAC, and ABTS assays. This is consistent with the differences in total flavonoid, total phenolic, and volatiles detected in both HD oil and its nanoemulsion. Meanwhile, the cytotoxicity on liver cancer cells (Hep-G2) was stronger using nanoemulsions (106 μg/mL) than using HD oil (274.8 μg/mL).

Abstract
Guava (Psidium guajava L.) is a fruit tree largely used in folk medicine in tropical and subtropical areas. This exotic species was introduced in a botanical garden in the northeast of Algeria in the 1950’s. The aim of this study is to estimate, for the first time, the antioxidant and anticholinesterase activities of chloroform, ethyl acetate and n-butanol extracts of P. guajava growing in Algeria. Six antioxidant assays were tested, results showed very important efficiency in free radical scavenging, reducing power and β-carotene bleaching of tested extracts. Values of IC50 or A0.5 of some samples were lower than those of standards. With regard to anticholinesterase activity, the inhibitory of both acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) was investigated. The extracts exhibited interesting capacity to inhibit these enzymes with low values of IC50 and even less than that of galanthamine. These activities were correlated with total phenolic content which was more important compared to the one found in extracts from trees growing in tropical and subtropical region. This could be due to resistance and adaptation of P. guajava grown in Algeria. The data obtained suggest the use of bioactive compounds from P. guajava leaves as antioxidant and drugs for symptomatic treatment of Alzheimer disease.

Abstract
A series of bis(4-amino-5-cyano-pyrimidines) was synthesized and evaluated as dual inhibitors of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). To further explore the multifunctional properties of the new derivatives, their antioxidant and antibacterial activities were also tested. The results showed that most of these compounds could effectively inhibit AChE and BChE. Particularly, compound 7c exhibited the best AChE inhibitory activity (IC50 = 5.72 ± 1.53 μM), whereas compound 7h was identified as the most potent BChE inhibitor (IC50 = 12.19 ± 0.57 μM). Molecular modeling study revealed that compounds 7c, 7f, and 7b showed a higher inhibitory activity than that of galantamine against both AChE and BChE. Anticholinesterase activity of compounds 7h, 7b, and 7c was significant in vitro and in silico for both enzymes, since these compounds have hydrophobic rings (Br-phenyl, dimethyl, and methoxyphenyl), which bind very well in both sites. In addition to cholinesterase inhibitory activities, these compounds showed different levels of antioxidant activities. Indeed, in the superoxide-dimethyl sulfoxide alkaline assay, compound 7j showed very high inhibition (IC50 = 0.37 ± 0.28 μM). Also, compound 7l exhibited strong and good antibacterial activity against Staphylococcus epidermidis and Staphylococcus aureus, respectively. Taking into account the results of biological evaluation, further modifications will be designed to increase potency on different targets. In this study, the obtained results can be a new starting point for further development of multifunctional agents for the treatment of Alzheimer's disease.
