Pyropia represents most domesticated seaweed in the world. Therefore, we aimed to determine if cultivation of the red macroalga Pyropia acanthophora E. C. Oliveira and Coll (Rhodophyta: Bangiales) under laboratory conditions would affect the presence and concentration of secondary metabolites. To accomplish this, experiments were performed with ambient sample and acclimated sample (laboratory conditions). The conditions of the culture room were as follows: 24 oC, salinity of 35%o, constant aeration, irradiance of 80 umol.photons.m-2.s-1 and photoperiod of 12 h, for 7 days. Ambient sample showed lower concentrations of allophycocyanin and phycoerythrin when compared to the acclimated sample, but phycocyanin concentration was higher in the ambient sample. Carotenoids showed higher concentrations in the acclimated sample when compared to the ambient sample. Total phenolics were insignificant, while total flavonoids were higher in the ambient sample. No pattern in the production of these secondary metabolites could be identified. On the other hand, the acclimated samples showed a greater inhibition of the free radical DPPH, indicating a higher antioxidant activity. Acclimatization under laboratory conditions, in which P. acanthophora is submerged in seawater, favors the production of economically important secondary metabolites as a result of submersion stress and changes in cultivation patterns, such as irradiance and photoperiod.

In Peru, Caulerpa filiformis is a marine algae listed as an invasive species. For years, its distribution has been considered to be in the north coast (Isla Lobos de Afuera and Piura) until a recent report of its distribution in the central coast (Ancash, Lima, and Ica). The present investigation aims to determine the main groups of secondary metabolites, total phenol content, and antioxidant activity of the methanolic extract of C. filiformis from Sechura Bay (Piura) and Paracas Bay (Ica). The main chemical groups were determined through phytochemical screening, the content of phenols by the Folin–Ciocalteu method, and antioxidant activity by the ABTS method (2,2-azinobis-[3-ethylbenzothiazoline-6-sulfonic acid]) and 2,2′-diphenyl-1-picrylhydrazyl (DPPH). The phytochemical screening of the methanolic extract of C. filiformis from Sechura Bay and Paracas Bay revealed the presence of carbohydrates, polyphenols, tannins, flavonoids, lipids, alkaloids, steroids, and triterpenes for both extracts. The total phenol content of the extract of C. filiformis from Sechura Bay (39.31 ± 0.39 mg of AGE/g extract) was significantly higher (p < 0.05) than that from Paracas Bay (18.78 ± 0.31 mg of AGE/g extract). In the ABTS and DPPH assays, the antioxidant capacity of the Sechura C. filiformis extract (IC50 = 3.49 ± 0.01 and 2.18 ± 0.02 mg/mL) was significantly higher (p < 0.05) than that of the Paracas C. filiformis extract (IC50 = 6.41 ± 0.02 and 2.42 ± 0.04 mg /mL). These findings suggest that the methanolic extract of C. filiformis is a source of secondary metabolites with an antioxidant potential.

Natural products black cumin—Nigella sativa (N. sativa) and wild garlic—Allium ursinum (AU) are known for their potential role in reducing cardiovascular risk factors, including antracycline chemotherapy. Therefore, this study investigates the effect of N. sativa and AU water and methanolic extracts in a cellular model of doxorubicin (doxo)-induced cardiotoxicity. The extracts were characterized using Ultraviolet-visible (UV-VIS) spectroscopy, Fourier-transform infrared (FT-IR) spectroscopy, Liquid Chromatography coupled with Mass Spectrometry (LC-MS) and Gas Chromatography coupled with Mass Spectrometry (GC-MS) techniques. Antioxidant activity was evaluated on H9c2 cells. Cytosolic and mitochondrial reactive oxygen species (ROS) release was evaluated using 2′,7′-dichlorofluorescin-diacetate (DHCF-DA) and mitochondria-targeted superoxide indicator (MitoSOX red), respectively. Mitochondrial membrane depolarization was evaluated by flow cytometry. LC-MS analysis identified 12 and 10 phenolic compounds in NSS and AU extracts, respectively, with flavonols as predominant compounds. FT-IR analysis identified the presence of carbohydrates, amino acids and lipids in both plants. GC-MS identified the sulfur compounds in the AU water extract. N. sativa seeds (NSS) methanolic extract had the highest antioxidant activity reducing both intracellular and mitochondrial ROS release. All extracts (excepting AU methanolic extract) preserved H9c2 cells viability. None of the investigated plants affected the mitochondrial membrane depolarization. N. sativa and AU are important sources of bioactive compounds with increased antioxidant activities, requiring different extraction solvents to obtain the pharmacological effects.

Ultrasonic Assisted Extraction

The increase in durian production results in the accumulation of durian peel waste. The bioactive component of durian peel has the potential to be used as an antioxidant. Thus, there is a need to carry out an extraction process to obtain  bioactive compounds from durian peel. However, conventional extraction methods cause damage to phenolic compounds due to oxidation, hydrolysis and ionization reactions during the extraction process. Therefore, durian peel extraction was carried out using ultrasonic assisted extraction method (UAE) in this study. The purpose of this study was to investigate the effect of varying ratios of durian peel to ethanol solvents and extraction time on the yield, total phenolics content, total flavonoids content and antioxidant activity. The results of the research data were analyzed using a two-factor completely randomized design, which included variations of the ratio of durian peel to ethanol solvents and extraction time The Duncan’s New Multiple Range Test (DNMRT) was carried out as a follow up test to determine the differences in each treatment at a significance level of 0.05. The results showed that the best treatment for peel extraction using ultrasonic assisted extraction was a 1: 9 ratio of durian peel to ethanol at an extraction time of 20 minutes. The extraction of durian peel under this condition gave the highest yield of 12.77 ± 0.16%, antioxidant activity (IC50) of 38.33 ± 0.12 ppm, total phenolic content of 63.30 ± 0.08 mgGAE / g and total flavonoids content of 47.53 ± 0.48 mgQE / g. In addition, total phenolics content and total flavonoid content showed a strong correlation to the antioxidant activity of durian peel extract.

Black horehound (Ballota nigra L.) is one of the important medicinal plants, which is a rich source of health-promoting essential oils. Salinity stress affects plant development and alters the quality and quantity of plants extracts and their composition. This study was aimed to investigate the effect of salinity on morphological, physiological characteristics, and secondary metabolites of B. nigra under greenhouse, and in vitro culture conditions. The plants were treated with different concentrations of NaCl (25, 50, 75, 100 mM) and fresh and dry weight of leaf and stem were measured as well as morphological characteristics of the plant. Plant growth was reduced with the increased salinity concentrations. The results showed that all growth-related traits and SPAD were decreased both in vivo and in vitro. Additionally, increased salt concentration affected the cell membrane integrity. Total phenolics content of plants growing in the greenhouse, increased by 21% at 50 mM NaCl, but at higher stress levels (100 mM NaCl), the amounts were decreased significantly. Total flavonoids contents followed similar patterns, with a slight difference. In addition, the maximum and minimum total phenolics contents of plants growing under in vitro condition were observed at 50 mM NaCl and control treatments, respectively. Increasing the salt concentration significantly affected the total flavonoids content, and as a result, the highest amount was observed in 50 and 75 mM NaCl treatments. Antioxidant activity was also measured. Among the NaCl treatments, the highest DPPH scavenging activities (IC50) under greenhouse and in vitro conditions were detected at 50 mM and 25 mM concentrations, respectively. In general, based on the results, with increasing the salinity level to 75 mM, the activities of CAT and APX were significantly upregulated in both greenhouse and in vitro culture conditions. A correlation between total phenolics and flavonoids contents as well as antioxidant activity were obtained. With shifting salinity stress, the type and the amount of the identified essential oil compounds changed. Compounds such as styrene, tridecanol, germacrene-D, beta-Ionone, beta-bisabolene, and caryophyllene oxide increased compared to the controlled treatment.

ABSTRACT: The objective of this study was to determine and correlate the extraction yields, antioxidant activity, total phenolics and total flavonoids from grape, mango and peanut agro-industrial by-products. The β-carotene/linoleic acid autoxidation system and scavenging capacity for DPPH and ABTS free radicals assays were used. The results were expressed in terms of lyophilized sample or dry extract. Mango bagasse exhibited the highest extraction yield (37.07%) followed by peanut skin (15.17%) and grape marc (7.92%). In terms of lyophilized sample, total phenolics did not vary significantly among the residues evaluated (average of 60.33mg EAG g-1); however, when they were expressed as dry extract grape marc exhibited the highest total phenolic (768.56±116.35mg GAE g-1), followed by peanut skin (404.40±13.22mg GAE g-1) and mango bagasse (160.25±4.52mg GAE g-1), Peanut skin exhibited the highest content of total flavonoids (2.44mg QE g-1), while grape marc (1.76mg QE g-1) and mango bagasse (1.70 mg QE g-1) showed no significant differences. The extraction yield showed strong negative linear correlation with total phenolic and total flavonoid. This study showed that peanut skin was the sample with the highest antioxidant activity and it was strongly influenced by total flavonoids. All extracts of byproducts showed antioxidant activity comparable to α-tocopherol, and they can be a source of natural compounds with potential to replace synthetic antioxidants such as BHT.
