Abstract
Objectives The aim of this study was to investigate the in vitro wound healing effects of the methanolic and aqueous extracts of Hypericum pseudolaeve N. Robson obtained by two different methods as well as its cytotoxicity, antioxidant activity, and selected phytochemical constituents. Materials and Methods Total phenolic and flavonoid contents were measured using spectrophotometry-based methods. The cytotoxic effects of the extracts on L929 mouse fibroblast cells were evaluated by and 2h-tetrazolium,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Moreover, migration and spreading of the treated fibroblast cells were assessed by cell scratch assay as an in vitro wound healing model. In addition, the chemical content of the species was determined by high pressure liquid chromatography (HPLC). Results The results of the cytotoxicity assay indicated that the methanolic and aqueous extract did not have any cytotoxic effect on fibroblast cells at concentrations up to 500 μg/mL. Fibroblast migration was significantly increased by 62 μg/mL concentration of the aqueous extracts compared to the negative control. The extracts showed good antioxidant activity and 16 phytochemical compounds were detected by HPLC, with the highest amount for epicatechin. Conclusion The results showed that Hypericum pseudolaeve extracts have wound healing potential and contain several important antioxidant phenolic compounds. This species deserves further investigation aiming to isolate and identify the active compounds.

Abstract
BACKGROUND Traditional cooling rice powder (bedak sejuk) is a fermented rice-based cosmetic that is applied topically on one's skin, as an overnight facial mask. According to user testimonies, bedak sejuk beautifies and whitens skin, whereby these benefits could be utilised as a potential melanoma chemopreventive agent. OBJECTIVE Hence, this study aimed to determine the effects of bedak sejuk made from Oryza sativa ssp. indica (Indica) and Oryza sativa ssp. japonica (Japonica) on UVB-induced B164A5 melanoma cells, and also identify the antioxidant capacities of both types of bedak sejuk. METHODS The optimum dose of Indica and Japonica bedak sejuk to treat the cells was determined via the MTT assay. Then, the antioxidant capacities of both types of bedak sejuk were determined using the FRAP assay. RESULTS From the MTT assay, it was found that Indica and Japonica bedak sejuk showed no cytotoxic effects towards the cells. Hence, no IC50 can be obtained and two of the higher doses, 50 and 100 g/L were chosen for treatment. In the FRAP assay, Indica bedak sejuk at 50 and 100 g/L showed FRAP values of 0.003 ± 0.001 μg AA (ascorbic acid)/g of bedak sejuk and 0.004 ± 0.0003 μg AA/g of bedak sejuk. Whereas Japonica bedak sejuk at 50 g/L had the same FRAP value as Indica bedak sejuk at 100 g/L. As for Japonica bedak sejuk at 100 g/L, it showed the highest antioxidant capacity with the FRAP value of 0.01 ± 0.0007 μg AA/g of bedak sejuk which was statistically significant (p < 0.05) when compared to other tested concentrations. CONCLUSION In conclusion, Japonica bedak sejuk has a higher antioxidant capacity compared to Indica bedak sejuk despite both being not cytotoxic towards the cells. Regardless, further investigations need to be done before bedak sejuk could be developed as potential melanoma chemoprevention agents.

Abstract
Although a vast number of Aloe species are known, only the Aloe vera and Aloe arborescens species are currently used by cosmetic and pharmaceutical industries. Therefore, the current study aims to complete the existent literature data with new information on the phytochemical composition of some lesser-known Aloe species, with the main focus on carotenoids and fatty acids. Among the analyzed species, Aloe aculeata and Aloe ferox had the highest content in carotenoids, the major pigments being lutein and β-carotene (according to HPLC analysis). The fatty acid profile of each Aloe species was analysed by GC–MS. Linolenic and linoleic acids were the major polyunsaturated fatty acids found in higher percent in Aloe ferox, Aloe spectabilis and Aloe marlothii. Instead, Aloe aculeata proved to have a distinct fatty acid profile, rich in monounsaturated fatty acids. Species such as Aloe arborescens and Aloe marlothii proved to have the highest antioxidant potential according to data of DPPH, ORAC, HPS assays, even if the richest one in vitamin C was found to be Aloe spectabilis. Though the scientific research is mainly focused on the common species Aloe barbadensis, the current data suggests that other Aloe species could receive more attention from industry part, being great sources of bioactive compounds.![]()

Abstract
BACKGROUND The inhibition of α-amylase and α-glucosidase activities is one of the major practical strategies for the control of postprandial hyperglycemia. Salvia officinalis L. is known by its various bioactive compounds and its effective therapeutic properties towards illnesses including diabetes. OBJECTIVE The present study aimed to evaluate the in vitro inhibitory effect of S. officinalis on key digestive enzymes linked to type 2 diabetes and to identify its hemolytic effect. METHODS Hydro-methanol decoction extract and fractions of ethyl acetate and n-butanol were investigated for their in vitro α-amylase and α-glucosidase inhibitory activities, compared to acarbose as a standard. Furthermore, they were evaluated for their hemolytic effect. RESULTS Phytochemical composition demonstrated the richness of S. officinalis in secondary metabolites. Extract and fractions inhibited the activity of both enzymes. They showed weak hemolytic activity. Quantitative estimation of total phenolic and flavonoids revealed that ethyl acetate fraction contained the highest amount of these compounds (450.51 ± 0.6 μg GAE/mg DE and 352.01 ± 0.78 μg CE/mg of DE, respectively). It showed the best antidiabetic activity tested both by α-amylase and α-glucosidase assays (IC50 = 46.52 ± 2.68 and 104.58 ± 0.06 μg/mL, respectively). Moreover, this fraction showed the least hemolytic effect (11.58 ± 0.1%). CONCLUSIONS S. officinalis extract and fractions are promising sources of α-amylase and α-glucosidase inhibitors.

Abstract
Aloe vera has been traditionally used to treat skin injuries (burns, cuts, insect bites, and eczemas) and digestive problems because its anti-inflammatory, antimicrobial, and wound healing properties. Research on this medicinal plant has been aimed at validating traditional uses and deepening the mechanism of action, identifying the compounds responsible for these activities. The most investigated active compounds are aloe-emodin, aloin, aloesin, emodin, and acemannan. Likewise, new actions have been investigated for Aloe vera and its active compounds. This review provides an overview of current pharmacological studies (in vitro, in vivo, and clinical trials), written in English during the last six years (2014–2019). In particular, new pharmacological data research has shown that most studies refer to anti-cancer action, skin and digestive protective activity, and antimicrobial properties. Most recent works are in vitro and in vivo. Clinical trials have been conducted just with Aloe vera, but not with isolated compounds; therefore, it would be interesting to study the clinical effect of relevant metabolites in different human conditions and pathologies. The promising results of these studies in basic research encourage a greater number of clinical trials to test the clinical application of Aloe vera and its main compounds, particularly on bone protection, cancer, and diabetes.

Abstract
Inflammatory bowel disease (IBD) is one of the predominant intestinal diseases associated with chronic inflammation and ulceration of the colon. This study explored the ameliorative effect of Aloe vera extract (Aloe) and/or heat-killed Lactobacillus plantarum L.137 (HK L.137) on dextran sodium sulfate (DSS)-induced colitis in mice. Aloe and/or HK L.137 were supplied for 9 days and the mice were challenged with DSS for 7 days. The DSS group demonstrated bloody diarrhea, colitis of high histologic grade, increased nuclear factor-kappa B (NF-κB) p65, inducible nitric oxide synthase (iNOS), myeloperoxidase (MPO), interleukin (IL)-6, and tumor necrosis factor (TNF)-α, and decreased IL-10 expression. These alterations were dwindled in DSS-induced mice treated with Aloe and HK L.137 separately. Aloe and HK L.137 together have augmented the therapeutic effect of each other. In conclusion, our findings demonstrated that Aloe and/or HK L.137 ameliorated DSS-induced colitis by promoting the secretion of anti-inflammatory cytokines and suppressing pro-inflammatory mediators. This study indicated that A. vera may function synergistically with HK L.137 to confer an effective strategy to prevent colitis.

Abstract
Aloe vera (AV) and tetracycline hydrochloride (TCH) exhibit significant properties such as anti-inflammatory, antioxidant and anti-bacterial activities to facilitate skin tissue engineering. The present study aims to develop poly-ε-caprolactone (PCL)/ AV containing curcumin (CUR), and TCH loaded hybrid nanofibrous scaffolds to validate the synergistic effect on the fibroblast proliferation and antimicrobial activity against Gram-positive and Gram-negative bacteria for wound healing. PCL/AV, PCL/CUR, PCL/AV/CUR and PCL/AV/TCH hybrid nanofibrous mats were fabricated using an electrospinning technique and were characterized for surface morphology, the successful incorporation of active compounds, hydrophilicity and the mechanical property of nanofibers. SEM revealed that there was a decrease in the fiber diameter (ranging from 360 to 770 nm) upon the addition of AV, CUR and TCH in PCL nanofibers, which were randomly oriented with bead free morphology. FTIR spectra of various electrospun samples confirmed the successful incorporation of AV, CUR and TCH into the PCL nanofibers. The fabricated nanofibrous scaffolds possessed mechanical properties within the range of human skin. The biocompatibility of electrospun nanofibrous scaffolds were evaluated on primary human dermal fibroblasts (hDF) by MTS assay, CMFDA, Sirius red and F-actin stainings. The results showed that the fabricated PCL/AV/CUR and PCL/AV/TCH nanofibrous scaffolds were non-toxic and had the potential for wound healing applications. The disc diffusion assay confirmed that the electrospun nanofibrous scaffolds possessed antibacterial activity and provided an effective wound dressing for skin tissue engineering.

Abstract
The present study was conducted to determine the total phenolics, flavonoids, flavonols, anthocyanin, and carotenoids as well as the antioxidant activity of 10 different Crozophora tinctoria accessions originated from Iran. The highest contents of total phenolics, flavonoids, flavonols, anthocyanin, and carotenoids were detected in C.t (2), C.t (10), C.t (10), C.t (9), and C.t (3) accessions, respectively. The highest antioxidant activities of the samples, evaluated using 1,1-diphenyl-2-picrylhydrazyl and phosphomolibdate assays, were detected in C.t (8) and C.t (3), respectively. The highest phenyl aminolyase activity was observed in C.t (4). Ten phenolic compounds, including quercetin, catechin, ellagic acid, rosmarinic acid, hesperetin, eugenol, hesperidin, carvacrol, thymol, and kaempferol were identified and quantified using high-performance liquid chromatography (HPLC) technique. The best anticancer activity against HeLa cell lines was observed at C.t (8) accession, originated from Qazvin Region. This study confirmed that the C. tinctoria accessions with rich phenolics compounds may be recommended as a novel source of natural antioxidants for future aims in medicinal fields. PRACTICAL APPLICATIONS: According to this findings there was high variation among phenolics compounds of C. tinctoria which is revealed by HPLC analysis. This study identified phenolic compounds with antioxidant and anticancer activity in Iranian accessions of C. tinctoria. With an increase in the rate of cancer disease, superior accessions of C. tinctoria may be recommended as a novel source of natural antioxidants for ethno pharmacological aims as cancer therapy, and also in nutraceutical fields.

Abstract
Many studies have proved that bioactive components of Aloe vera have an anti-inflammatory effect and support lipid and carbohydrate metabolism, helping to maintain normal sugar and cholesterol levels in blood and normal body weight. When aloe is applied externally, it accelerates the regeneration of the damaged skin. Aloe contains antioxidants, which may increase the shelf-life and nutritional value of food; therefore, it is widely used in cosmetic, pharmaceutical and food industry. An antioxidant activity was shown for leaf's skin, flowers and gel of aloe. In this work the future of A. vera as effective antioxidants is primarily discussed and expected trends are summarised. Furthermore, the bioactive components and the health-promoting effects of A. vera are investigated.

Abstract
Triterpenoids, tocopherols, and phytosterols presented in unsaponifiable fraction of grape seed oil have several beneficial effects comprising antioxidant, anti-inflammatory, and antitumor capacities. In this study, the unsaponifiable fraction of three Tunisian grape seed varieties (Vitis vinifera L.), namely Merlot, Carignan, and Syrah, was investigated. The identified compounds were two triterpenic compounds (β-amyrin, lanosterol), six phytosterols (campesterol, ∆7 -avenasterol, stigmasterol, β-sitosterol, β-sitostanol, cholesterol), and three tocopherols (α, β, and γ tocopherols). The unsaponifiable fraction had significant protection against oxidative damage by modulating NO production and antioxidant activity. Statistical analysis showed the presence of three clusters of varieties associated to specific composition patterns. These results clearly demonstrated that unsaponifiable fraction profiles of grape species could be considered as a complementary data to the existing taxonomic evidence and classification purposes. PRACTICAL APPLICATIONS: Recently, much attention has been focused to substitute artificial antioxidant by others originating from natural products as plant matrices. The unsaponifiable fraction of grape seed oils is an interesting source of bioactive components like phytosterols, tocopherols, triterpenoids, and other various components. These components are known for their antitumor, anti-inflammatory and antioxidant capacities.

Abstract
Background Premature skin aging results from exposure to a range of environmental factors, primarily ultraviolet radiation, but also high‐energy visible light in the blue spectrum, infrared radiation, and environmental pollution. These extrinsic factors result in the generation of reactive oxygen species which promote photoaging and DNA damage resulting in skin cancers. Aims To formulate skincare products utilizing a new coating applied to zinc oxide and titanium dioxide particles and complimentary skincare ingredients to provide broad protection against a range of environmental insults. Methods A cross‐polymer, multifunctional coating of silicate, polyalkylsilsesquioxane, and polydimethylsiloxane moieties increases the photostability and decreases the reactivity of mineral sunscreen agents when interacting with energy sources. These products are also formulated with antioxidants to minimize free radical propagation. Additionally, this coating improves the esthetic feel of mineral sunscreens, while the appearance is enhanced by formulating products with a blend of iron oxides. Results A series of in vitro and ex vivo studies demonstrated the ability of mineral‐based products formulated with the new multifunctional coating to provide protection against ultraviolet radiation, high‐energy visible light, infrared radiation, and environmental pollution. Conclusion Newly formulated mineral‐based skincare products provide environmental protection, are ecologically safe, and can replace chemical‐based sunscreen ingredients.

Water deficit and abscisic acid treatments increase the expression of a glucomannan mannosyltransferase gene (GMMT) in Aloe vera Burm. F. PHYTOCHEMISTRY 2019; 159:90-101.

Abstract
The main polysaccharide of the gel present in the leaves of or Aloe vera Burm.F., (Aloe barbadensis Miller) a xerophytic crassulacean acid metabolism (CAM) plant, is an acetylated glucomannan named acemannan. This polysaccharide is responsible for the succulence of the plant, helping it to retain water. In this study we determined using polysaccharide analysis by carbohydrate gel electrophoresis (PACE) that the acemannan is a glucomannan without galactose side branches. We also investigated the expression of the gene responsible for acemannan backbone synthesis, encoding a glucomannan mannosyltransferase (GMMT, EC 2.4.1.32), since there are no previous reports on GMMT expression under water stress in general and specifically in Aloe vera. It was found by in silico analyses that the GMMT gene belongs to the cellulose synthase-like A type-9 (CSLA9) subfamily. Using RT-qPCR it was found that the expression of GMMT increased significantly in Aloe vera plants subjected to water stress. This expression correlates with an increase of endogenous ABA levels, suggesting that the gene expression could be regulated by ABA. To corroborate this hypothesis, exogenous ABA was applied to non-water-stressed plants, resulting in a significant increase of GMMT expression after 48 h of ABA treatment.

Abstract
Milk components have the ability to interact with functional compounds, such as polyphenols. This may result in altered biological activity of the compounds, and changes in the technological properties of dairy products. The objective of this study was to examine the effect of the addition of yerba mate (YM) on the physico-chemical and sensory properties of fresh cheese (FC) during storage (21 days). Different concentrations of YM were used for FC production: 0.0% (control), 0.5% (FC5), 1.0% (FC10) and 2.0% (FC20); and the bioactive compound concentration, antioxidant activity, color, texture, structure and sensory acceptance were evaluated. YM conferred antioxidant activity to FC; and affected the color, texture and structure. Storage time influenced all evaluated parameters except for color. FCs with 0.5 and 1.0% YM were scored as having higher sensory acceptability than FC with 2.0% YM. However, all supplemented FCs were well accepted by consumers (scores above 6). The YM could represent a source of bioactive compounds to improve the biological activity of dairy products.

Abstract
Aloe genus plants, distributed in Old World, are widely known and have been used for centuries as topical and oral therapeutic agents due to their health, beauty, medicinal, and skin care properties. Among the well-investigated Aloe species are A. arborescens, A. barbadensis, A. ferox, and A. vera. Today, they account among the most economically important medicinal plants and are commonly used in primary health treatment, where they play a pivotal role in the treatment of various types of diseases via the modulation of biochemical and molecular pathways, besides being a rich source of valuable phytochemicals. In the present review, we summarized the recent advances in botany, phytochemical composition, ethnobotanical uses, food preservation, and the preclinical and clinical efficacy of Aloe plants. These data will be helpful to provide future directions for the industrial and medicinal use of Aloe plants.

Abstract
Drought stress is one of the most important stresses adversely affecting plant growth and yield production. Due to the importance of global warming, the investigation of drought effects on the growth and quality of medical plants is of vital importance. Accordingly, a two-year field experiment was conducted in 2013-2014 to determine the effects of drought levels and plant species on Balangu (Lallemantia sp.) growth and physiological properties including medicinal content. The experiment was a split plot in which the drought levels (main plots) including control (D1, moisture field capacity, water potential at, 0.5 atm), moderate stress (D2, 6.5 atm) and severe stress (D3, 9.5 atm), and the Balangu species (sub plots) including Lallemantia royleana (Benth) (L1) and L. iberica (L2) were tested as the experimental treatments. Plant yield, oil content and the biochemical properties (i.e. medicinal content) including phenolic compounds, proline, carotenoids, and the activity of antioxidant enzymes including peroxidase (EC 1.11.1), super oxide dismutase (SOD, EC 1.15.1.1)) and ascorbate peroxidase (APX, EC 1.11.1.11) were determined. Drought stress significantly decreased crop yield and oil content. However, the production of phenolic compounds and proline as well as the activity of antioxidant enzymes, SOD and APX increased under stress. The species L2 was the more tolerant species under drought stress. The interesting point about this research work is the increased production of secondary metabolites (i.e. phenolic compounds) under stress, affecting both Balangu response and medicinal properties. Accordingly, it may be possible to regulate the production of secondary metabolites (medicinal contents) in Balangu species by adjusting the irrigating practices.

Abstract
Abstract
Quinoa (Chenopodium quinoa Willd.) has been nutritionally highlighted when compared to other grains. In recent years the research on this pseudocereal has increased. In this work, six quinoa samples were studied: three from Peru, one from Brazil and two commercial samples. The samples were physically and physicochemically characterized, including macro- and micronutrient analysis, phenolic compounds content and antioxidant activity. Black, red and white samples showed as main difference the size, weight, ashes and dietary fibre content. Black samples were the smallest and lightest and had the lowest starch content but presented the highest levels of ashes and dietary fibre. The protein content (16.9 %) in the white Brazilian variety was higher than the others. Red and black samples had the highest levels of most minerals analysed. The antioxidant capacity measured by the DPPH method was higher for black and red samples in comparison with the white ones. However, the white Brazilian variety showed a significantly higher antioxidant capacity measured by the ABTS assay. With regard to the phenolic content, a difference was found between the samples which ranged from 55.5 to 95.5 g GAE 100 g−1. The colour of the grain was found as not related to a higher content of phenolic compounds. Because their compositions are generally similar to light-coloured grains, and in some parameters such as dietary fibre and content of some micronutrients are superior, the grains of dark-coloured quinoa varieties (RPP, BCP) would have to be explored to develop foods that take advantage of this colour diversity.
