Abstract
PURPOSE Essential oils (EOs) obtained from spices, herbs, and medicinal plants are well known in traditional medicine and are an area of interest due to their various biological activities. Therefore, the present study investigates the chemical composition, phytochemical properties, as well as the biological activity of EOs, recovered from un-irradiated and irradiated (2.5, 5, and 10 kGy) caraway seeds. MATERIALS AND METHODS Carum carvi L. seeds were irradiated with gamma irradiation at dose levels 2.5, 5, and 10 kGy, then EOs were recovered from all the samples. The chemical composition, phenols, and flavonoids content were evaluated. As well, antimicrobial and antitumor activities against the two cell lines [colorectal adenocarcinoma (Caco-2) and liver cancer (HepG-2)] were investigated. RESULTS The results indicated the percentage of oil increased by radiation, especially a dose of 10 kGy, which gave the highest percentage (3.50%) compared to the control. Also, the Gas Chromatography/Mass Spectrometry (GC-MS) analysis revealed the presence of 26 compounds in the essential oil extracts. The main constituent of caraway seeds EOs was Carvone followed by Limonene. According to the results, there was an increase in the content of phenols and flavonoids by using gamma rays compared with control, the maximum increase was observed at dose level 10 kGy (13.70 and 7.38 mg/g oil, respectively) followed by 5 kGy (11.20 and 5.86 mg/g oil, respectively). The antioxidant properties of the caraway essential oils were increased by increasing the irradiation dose level (2.5-10 kGy) analyzed by DPPH radical and metal chelating activity. Caraway essential oils have an antimicrobial action against Gram-positive and Gram-negative bacteria as well as fungi. The antimicrobial activity was increased as the irradiation dose was raised and the10 kGy dose was more effective in suppressing the growth of bacteria and fungi. Additionally, the caraway essential oils have anticancer activity against the two cell lines studied; colorectal adenocarcinoma (Caco-2) and liver cancer cell line (HepG-2) as reduced the cell viability and density. CONCLUSION The 10 kGy dose was more effective for oil yield, phenols, flavonoids, and antioxidant activity as well as antibacterial and antifungal activities. Furthermore, the caraway essential oils indicated anticancer activity against the two cell lines studied; colorectal adenocarcinoma (Caco-2) and liver cancer cell line (HepG-2) as reduced the cell viability and density. So caraway could be considered an important herb with multiple therapeutic uses.

Abstract
Moringa oleifera Lam (syn. M. ptreygosperma Gaertn.) leaves are globally acclaimed for their nutritional content and mitigation of malnutrition. In most impoverished rural communities including Limpopo, Mpumalanga and KwaZulu Natal of South Africa, powdered leaves of Moringa oleifera are applied as a nutritional supplement for readily available food such as porridge for malnourished children and even breast-feeding mothers. Widely practiced and admired is also the use of the plant seed in the do-it-yourself purification of water by rural South Africans. This study aimed at identifying the chemical and nutritional marker compounds present in South African Moringa oleifera seed oils using high resolution 1-2-dimension gas chromatography in order to give scientific validation to its uses in cosmetics and particularly in culinary practices. Results obtained from two-dimension tandem mass spectrometry chemical signature revealed over 250 compounds, five times more than those reported from one-dimension gas chromatography. Whereas previous reports from gas chromatography-mass spectrometry analysis reported oleic acid (70–78%) as the major compound from oil samples from other countries, M. oleifera seed oil from South Africa is marked by cis-13-octadeaconic acid with 78.62% and 41.9% as the predominant monounsaturated fatty acid in the hexane and dichloromethane extracts respectively. This was followed by cis-vaccenic acid, an isomer of oleic acid at 51% in the acetone extract, 9-octadecanoic acid-(z)-methyl ester at 39.18%, 21.34% and 10.06% in dichloromethane, hexane and acetone extracts respectively. However, a principal component analysis with R2 = 0.98 of the two-dimension tandem mass spectrometry cum chemometric analysis indicated n-hexadecanoic acid, oleic acid, 9-octadecanoic acid-(z)-methyl ester and cis-vaccenic acid with a probability of 0.96, 0.88, 0.80 and 0.79 respectively as the marker compounds that should be used for the quality control of moringa seed oils from South Africa. This study demonstrates that South African Moringa oleifera oils contain C-18 monounsaturated fatty acids similar to oils from Egypt (76.2%), Thailand (71.6%) and Pakistan (78.5%) just to mention but a few. These fatty acids are sunflower and olive oil type-compounds and therefore place moringa seed oil for consideration as a cooking oil amongst its other uses.

Gutiérrez‐Luna K, Ansorena D, Astiasarán I. Fatty acid profile, sterols, and squalene content comparison between two conventional (olive oil and linseed oil) and three non‐conventional vegetable oils (echium oil, hempseed oil, and moringa oil). J Food Sci 2022; 87:1489-1499. [PMID: 35279846 PMCID: PMC9313813 DOI: 10.1111/1750-3841.16111] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 02/11/2022] [Accepted: 02/14/2022] [Indexed: 12/31/2022]
Abstract
Abstract New sources of bioactive compounds are constantly explored for reformulating healthier foods. This work aimed to explore and characterize the fatty acid profile and sterol content of three non‐conventional oils used in functional food products (hempseed oil, moringa oil, and echium oil) and to compare them with two conventional ones (extra virgin olive oil [EVOO] and linseed oil). Oxidative stability was assessed by determining their acidity value and peroxide content. All oils showed adequate values for acidity and oxidation status. Echium and hempseed oils showed a high content of polyunsaturated fatty acids (>70%), especially omega‐3 fatty acids, while moringa oil was rich in oleic acid. Echium oil, hempseed oil, and moringa oil presented higher sterol content than EVOO, but lower than that of linseed oil. Sitosterol was the most abundant sterol in all samples (97.88–275.36 mg/100 g oil), except in echium oil, where campesterol (170.62 mg/100 g oil) was the major sterol. Squalene was only found in significant amounts in EVOO. In conclusion, non‐conventional oils seem to be interesting sources of bioactive compounds and have great potential for the food industry. Practical Application Non‐conventional vegetable oils can be used as alternative sources of lipids in a variety of food products. Additionally, these oils have great potential to be included in the formulation of functional ingredients for the delivery of omega‐3 fatty acids, antioxidants, fiber, among others.

Abstract
Compared to its leaf, few studies have been reported on the seeds of Moringa oleifera Lam. Metabolites profiling analysis of M. oleifera seed methanolic extract (ME) and its fixed oil (MO) was attempted via LC/MS and GC/MS. LC/MS analysis of M. oleifera seeds annotated 84 peaks of which glucosinolates and their corresponding acetyl isomers were abundant. GC/MS of seed oil revealed the abundance of fatty acids with oleic acid at 34.3%. ME exhibited significant anti-Helicobacter pylori activity with MIC50 0.92 µg/mL, nearly one-half that of Clarithromycin. Fixed oil (MO) showed a nonselective anti-inflammatory effect with IC50= 24.4 ± 0.8 µg/mL correlated to Ibuprofen. To unravel the mechanism of the anti-H. pylori activity a molecular docking study of the principal components of the ME has been performed, using H. pylori urease enzyme. Interactions with Ni2+ ions and amino acid residue in the active site, which are crucial for the enzyme's biochemical role, are evidenced.

Abstract
The objective of the present study is to determine the antioxidant and anticancer activities of Nostoc linckia extracts cultivated under heavy metal stress conditions (0.44, 0.88, and 1.76 mg/L for zinc and 0.158, 0.316, 0.632 mg/L for copper). Phycobiliprotein, phenolic compounds, flavonoids, and tannins were measured. Active ingredients of extracts were evaluated by GC-mass spectroscopy. The obtained results revealed that higher zinc and copper concentrations showed growth inhibition while 0.22 mg/L (Zn) and 0.079 mg/L (Cu) enhanced growth, reaching its maximum on the 25th day. Increases in catalase, lipids peroxidation, and antioxidants, as well as tannins and flavonoids, have been induced by integration of 0.88 mg/L (Zn) and 0.316 mg/L (Cu). Elevation of Zn concentration induced augmentation of antioxidant activity of crude extract (DPPH or ABTS), with superior activity at 0.44 mg/L zinc concentration (81.22%). The anticancer activity of Nostoc linckia extract (0.44 mg/L Zn) tested against four cancer cell lines: A549, Hela, HCT 116, and MCF-7. The extract at 500 µg/mL appeared the lowest cell viability of tested cell lines. The promising extract (0.44 mg/L Zn) recorded the lowest cell viability of 25.57% in cervical cell line, 29.74% in breast cell line, 33.10% in lung cell line and 34.53% in the colon cell line. The antioxidant active extract showed significant stability against pH with attributed increase in antioxidant activity in the range between 8–12. The extract can be used effectively as a natural antioxidant and anticancer after progressive testing.

Abstract
Aflatoxigenic fungi and aflatoxins are still a principal challenge that threatened peanut production, marketing, and handling. This study aimed to face the problem using bioactive materials, which reduce fungi and mycotoxin contamination, Moringa extracts may be suitable for solving this challenge. Also, the study was compared the extracts of leaves and oil-free seeds. Fresh leaves and seeds were collected, dried, and milled, while oil was collected by cold pressing. The extracts were evaluated for total phenols, flavonoids, and antioxidants, the oil contents of fatty acids, tocopherol, and sterols were determined. An emulsion for protecting peanuts compositing of leaves extract carried by Moringa oil, and commercial emulsifier. Leaves extract evaluation reflected distinct properties of its fibers, total phenols, and flavonoids. It was recorded a microbial inhibition of bacteria and fungi. The values for both minimal inhibition and fungicidal concentrations were recorded at 3.2 mg/mL and 490 μg/L, respectively. For oil, it showed a unique content, as oleic acid was the main fatty acid, with an affinity between palmitic and behenic in their ratios. Also, oil was recorded by high contents of alpha-tocopherol and Δ7-Campesterol, with 1.166 mg/kg oil as total sterols content. The leaves extract has also a unique capacity to inhibit toxigenic fungi. By applying the composite emulsion for peanut coating, results expressed a high CFU-count inhibition when it was inoculated by A. flavus strain compared to the control.

Abstract
Tributyltin (TBT) is an organotin compound widely used as a biocide in antifouling paints. Moringa oleifera oil (MOO) has a promising antioxidant potential, which necessitates further exploration. This study was conducted to investigate the potential protective effect of MOO against TBT-induced brain toxicity. The 30 rats were grouped into five groups (six each), Group I negative control, Group II positive control (vehicle), Group III MOO (5 ml/kg body weight [b.wt.]), Group IV TBT (10 mg/kg b.wt.), and Group V TBT & MOO. All treatments were given orally for 28 days. Thereafter, brains were exposed to oxidative stress and neurological parameters analyses. Histopathological and immunohistochemical (caspase-3, Bax, Bcl-2) examinations were also carried out. In rats administered TBT, increased malondialdehyde level, decreased reduced glutathione, and low total antioxidant capacity levels were in support of oxidative stress mechanism. Neurotoxicity was indicated by high nitric oxide level and increased acetylcholinestrase activity. Along with the histopathological alterations, the dysregulated expression of caspase-3, Bax, and Bcl-2 were indicative of the apoptotic mechanism mediated by TBT. Co-administration of MOO with TBT ameliorated the aforementioned toxic effects. In conclusion, TBT causes brain toxicity via oxidative, nitrosative, and apoptotic mechanisms. MOO demonstrates protective effect against TBT-induced brain toxicity mostly via potent antioxidant and antiapoptotic properties.

Abstract
This study investigates the application of green technologies (microwave and ultrasound pretreatment) in the extraction of Moringa oleifera Lam. seed oil and its effects on oil expression, oil quality, and bioactive component. Moringa seeds were pretreated with microwave (90 W, 60 s) or ultrasound (50 W, 1 h) before mechanical expression. A separate group received no pretreatment before oil extraction. Oils from these groups were then compared. Results show that oil yield increased with ultrasound pretreatment (1.24%) and significantly increased with microwave pretreatment (3.11%). For oil flow rate, the microwave and ultrasound pretreatment resulted in faster extraction (7.67 and 6.93 kg/h respectively) as compared with the control (6.51 kg/h). For physicochemical parameters, the microwave and ultrasound group had significantly less free fatty acids and significantly greater unsaponifiable matter as compared with the control. For fatty acid composition, results show that moringa seeds procured from Davao Oriental had greater oleic acid content (~77%) as compared with those reported by other literature. For phytosterol content, the predominant phytosterols found were β-sitosterol, stigmasterol, and campesterol. Microwave and ultrasound pretreatment significantly increased total phytosterol (680.58 and 369.32 mg/kg respectively) as compared with the control (72.69 mg/kg) due to the mass transfer of the phytosterols. Microwave and ultrasound pretreatment also led to stigmastanol formation. For antioxidant activity, a comparison of both DPPH and FRAP assays depicts that the microwave group exhibited the best overall antioxidant activity. Lastly, for oil stability, a lower peroxide value was found in the microwave and ultrasound groups across time intervals, which may be attributed to their antioxidant activity. In summary, ultrasound and microwave pretreatment can improve oil expression, oil quality, and bioactive content of the mechanically expressed moringa oils.

Abstract
Vegetable oils can be adjusted by different methods to enhance their commercial applications and to increase their pure quality nutrition. One of the most leisurely ways of creating new innovative products with desirable textured and oxidative properties is the mixing of vegetable fats/oils of various properties. Pure sunflower (SFO) blended with pure moringa (MOO) and sesame (SEO) oils in the ratio of 95:5 and 90:10 w/w. The outcomes showed that the highest acid value was observed at SFO + SEO 10% (0.782). Sunflower oil stabilized when blended with MOO and the levels of conjugated dienes (CD) and trienes (CT) were depressed compared to control. The TPC value was higher when the sunflower blended with moringa oil. The highest scavenging activity percentage was observed in SFO + MOO 5% and SFO + SEO 10% respectively. Meanwhile, the highest induction period at 100 °C was 11.45 hours in the treatment of SFO + MOO 5%. The master fatty acids in the sunflower and moringa oils are combined (SFO:MOO, 90:10), oleic, and palmitic acids. It seems from the current findings that suitable mixing of high linoleic oils with MOO will result in oil mixtures that can satisfy nutritional wants with expanded balance for home cooking and deep-frying.

Abstract
Background Chlorella vulgaris is a microalga potentially used for pharmaceutical, animal feed, food supplement, aquaculture and cosmetics. The current study aims to study the antioxidant and prooxidant effect of Chlorella vulgaris cultivated under various conc. of copper ions. Methods The axenic green microalgal culture of Chlorella vulgaris was subjected to copper stress conditions (0.00, 0.079, 0.158, 0.316 and 0.632 mg/L). The growth rate was measured at OD680 nm and by dry weight (DW). Moreover, the Antioxidant activity against DPPH and ABTS radical, pigments and phytochemical compounds of the crude extracts (methylene chloride: Methanol, 1:1) were evaluated. The promising Cu crude extract (0.316 mg/L) further fractionated into twenty-one fractions by silica gel column chromatography using hexane, chloroform and ethyl acetate as a mobile phase. Results The obtained results reported that nine out of these fractions exhibited more than 50% antioxidant activity and anticancer activity against Hela cancer cell lines. Based on IC50, fraction No. 7 was found to be the most effective fraction possessing a significant increase in both antioxidant and anticancer potency. Separation of active compound (s) in fraction No 7 was performed using precoated silica gel plates (TLC F254) with ethyl acetate: hexane (9:1 v/v) as mobile phase. Confirmation of active compound separation was achieved by two-dimensional TLC and visualization of the separated compound by UV lamp. The complete identification of the separated active compound was performed by UV- Vis- spectrophotometric absorption, IR, MS, H1-NMRT C13-NMR. The isolated compound ((2E,7R,11R)-3,7,11,15-Tetramethyl-2-hexadecenol) have high antioxidant activity with IC50 (10.59 μg/ml) against DPPH radical assay and comparable to the capacities of the positive controls, Butylated hydroxy toluene [BHT] (IC50 11.2 μg/ml) and Vitamin C (IC50 12.9 μg/ml). Furthermore, pure isolated compound exhibited a potent anticancer activity against Hela cell line with IC50 (4.38 μg/ml) compared to Doxorubicin (DOX) as synthetic drug (13.3 μg/ml). In addition, the interaction of the pure compound with Hela cancer cell line and gene expression were evaluated. Conclusions The authors recommend cultivation of Chlorella vulgaris in large scale under various stress conditions for use the crude extracts and semi purified fractions for making a pharmaco-economic value in Egypt and other countries.

Abstract
Moringa oleifera Lam. (MO), which is widely consumed as both food and herbal medicine in tropical and subtropical regions, has a wide spectrum of health benefits. Yet, whether the oil obtained from MO seeds could affect (improve) the sleep activity remains unclear. Herein, we used the locomotor activity, pentobarbital-induced sleeping, and pentetrazol-induced convulsions test to examine sedative-hypnotic effects (SHE) of MO oil (MOO) and explored the underlying mechanisms. Besides, the main components of MOO like oleic acid, β-Sitosterol, and Stigmasterol were also evaluated. The results showed that they possessed good SHE. Except for oleic acid and Stigmasterol, they could significantly elevate γ-amino butyric acid (GABA) and reduce glutamic acid (Glu) levels in the hypothalamus of mice. Moreover, SHE was blocked by picrotoxin, flumazenil, and bicuculline, except for oleic acid, which could not be antagonized by picrotoxin. Molecular mechanisms showed that MOO and β-Sitosterol significantly upregulated the amount of protein-level expression of Glu decarboxylase-65 (GAD65) and α1-subunit of GABAA receptors in the hypothalamus of mice, not affecting GAD67, γ2 subunits. These data indicated that MOO modulates sleep architectures via activation of the GABAA-ergic systems.
