Abstract
Tissue succulence in plants involves the storage of water in one or more organs or tissues to assist in maintaining water potentials on daily or seasonal time scales. This drought-avoidance or drought-resistance strategy allows plants to occupy diverse environments including arid regions, regions with rocky soils, epiphytic habitats, and saline soils. Climate-resilient strategies are of increasing interest in the context of the global climate crisis, which is leading to hotter and drier conditions in many regions throughout the globe. Here, we describe a short history of succulent plants, the basic concepts of tissue succulence, the anatomical diversity of succulent morphologies and associated adaptive traits, the evolutionary, phylogenetic, and biogeographical diversity of succulent plants, extinction risks to succulents due to poaching from their natural environments, and the myriad uses and applications of economically important succulent species and the products derived from them. Lastly, we discuss current prospects for engineering tissue succulence to improve salinity and drought tolerance in crops.

Abstract
The rhizome tuber of Sauromatum giganteum is known as 'Bai Fuzi' in China and has been ethnomedicinally used to treat various neurological diseases. It is considered to possess anti-Parkinson's disease (PD) potential, but the active compounds responsible for that is still unclear. In this work, nineteen compounds were isolated and identified from rhizome tuber of this plant, among which four were firstly reported, i.e. berberine (1), nicotinamide (2), rutin (3) and 5-caffeoylquinic acid (4). Six compounds (1, 3, 4, 8, 14 and 15) exhibited moderate inhibitory activity against MAO-B with IC50 of 118.8, 45.6, 96.2, 65.8, 40.0, and 49.8 µM, and two compounds (3 and 4) displayed significant protective effect on 6-OHDA-induced PC-12 cell model. The molecular docking of the bioactive compounds and MAO-B was carried out to explore the binding mode. The findings revealed the potential of S. giganteum as anti-PD herb and its inclusion in TCM could be explored.

Effect of Agave Fructans on Changes in Chemistry, Morphology and Composition in the Biomass Growth of Milk Kefir Grains. Microorganisms 2023; 11:1570. [PMID: 37375072 DOI: 10.3390/microorganisms11061570] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2023] [Revised: 05/30/2023] [Accepted: 06/08/2023] [Indexed: 06/29/2023] Open
Abstract
Prebiotic effects have been attributed to agave fructans through bacterial and yeast fermentations, but there are few reports on their use as raw materials of a carbon source. Kefir milk is a fermented drink with lactic acid bacteria and yeast that coexist in a symbiotic association. During fermentation, these microorganisms mainly consume lactose and produce a polymeric matrix called kefiran, which is an exopolysaccharide composed mainly of water-soluble glucogalactan, suitable for the development of bio-degradable films. Using the biomass of microorganisms and proteins together can be a sustainable and innovative source of biopolymers. In this investigation, the effects of lactose-free milk as a culture medium and the addition of other carbon sources (dextrose, fructose, galactose, lactose, inulin and fructans) in concentrations of 2, 4 and 6% w/w, coupled with initial parameters such as temperature (20, 25 and 30 °C), % of starter inoculum (2, 5 and 10% w/w) was evaluated. The method of response surface analysis was performed to determine the optimum biomass production conditions at the start of the experiment. The response surface method showed that a 2% inoculum and a temperature of 25 °C were the best parameters for fermentation. The addition of 6% w/w agave fructans in the culture medium favored the growth of biomass (75.94%) with respect to the lactose-free culture medium. An increase in fat (3.76%), ash (5.57%) and protein (7.12%) content was observed when adding agave fructans. There was an important change in the diversity of microorganisms with an absence of lactose. These compounds have the potential to be used as a carbon source in a medium culture to increase kefir granule biomass. There was an important change in the diversity of microorganisms with an absence of lactose, where the applied image digital analysis led to the identification of the morphological changes in the kefir granules through modification of the profile of such microorganisms.

Toxicity and Anti-Inflammatory Effects of Agave sisalana Extract Derived from Agroindustrial Residue. PLANTS (BASEL, SWITZERLAND) 2023; 12:1523. [PMID: 37050149 PMCID: PMC10096503 DOI: 10.3390/plants12071523] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 12/06/2022] [Accepted: 12/15/2022] [Indexed: 06/19/2023]
Abstract
BACKGROUND In several countries, the leaf juice of Agave sisalana (also known as sisal) is widely used topically, especially as an antiseptic, and orally for the treatment of different pathologies. However, in Brazil, which is the largest producer of Agave sisalana, its residue, which represents the majority of its weight, has been thrown away. For this reason, the determination of the pharmacological and toxicological potentials of sisal residue and its possible therapeutic use is seen as a way to contribute to the sustainable development and social promotion of the largest producer of sisal in Brazil, the interior of Bahia State, which is among the poorest areas in the country. Given the scarcity of available scientific studies on the pharmacological and toxicological properties of sisal residue juice, this study aimed to promote the acid hydrolysis of this juice to potentiate the anti-inflammatory effect already described in the literature. Furthermore, it aimed to evaluate the toxicological profile of the hydrolyzed extract (EAH) and to determine its acute toxicity, as well as its side effects on the reproductive aspects of rats. METHOD The anti-inflammatory effect of EAH was evaluated in vitro using the induction of hemolysis by hypotonic solution and in vivo in rats using the carrageenan-induced paw edema test and the xylene-induced ear edema test. The acute toxicity, resulting from a single-dose administration, was investigated for some manifestation of toxic symptoms related to motor control and consciousness in rats. At a concentration of 100 mg/kg, by repeated doses, the reproductive toxicity effects of EAH in rats were assessed. RESULTS In vitro anti-inflammatory activity was positive using the human red blood cell membrane stabilization method. In both in vivo tests used to assess the anti-inflammatory activity, EAH (at three doses) significantly inhibited edema when compared to the control group. At a dose of 50 mg/kg, EAH exhibited a greater effect than indomethacin, a nonsteroidal anti-inflammatory drug with known activity. In vivo toxicological studies have shown that EAH does not present toxic effects when administered orally in a single dose, up to 1000 mg/kg. Finally, EAH promoted a gonadotoxic effect and increased the embryonic mortality rate after implantation. CONCLUSIONS It is suggested that the anti-edematogenic effect of the acid hydrolysis extract from sisal juice is due to the high concentration of steroidal sapogenins. Therefore, this extract can be considered a potential new anti-inflammatory or even an important sapogenin source for the development of steroidal glucocorticoids. However, further studies are needed to elucidate the chemical composition of sisal juice. Regarding toxicology studies, EAH did not show cytotoxic and clastogenic potentials, but it presented a powerful reproductive toxic effect in rats.

UPLC-ESI-MS/MS Profiling and Cytotoxic, Antioxidant, Anti-Inflammatory, Antidiabetic, and Antiobesity Activities of the Non-Polar Fractions of Salvia hispanica L. Aerial Parts. PLANTS (BASEL, SWITZERLAND) 2023; 12:1062. [PMID: 36903922 PMCID: PMC10005563 DOI: 10.3390/plants12051062] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Revised: 02/20/2023] [Accepted: 02/21/2023] [Indexed: 06/18/2023]
Abstract
Salvia hispanica L. is an annual herbaceous plant commonly known as "Chia". It has been recommended for therapeutic use because of its use as an excellent source of fatty acids, protein, dietary fibers, antioxidants, and omega-3 fatty acids. A literature survey concerning phytochemical and biological investigations of chia extracts revealed less attention towards the non-polar extracts of S. hispanica L. aerial parts, which motivates us to investigate their phytochemical constituents and biological potentials. The phytochemical investigation of the non-polar fractions of S. hispanica L. aerial parts resulted in the tentative identification of 42 compounds using UPLC-ESI-MS/MS analysis with the isolation of β-sitosterol (1), betulinic acid (2), oleanolic acid (3), and β-sitosterol-3-O-β-D-glucoside (4). GLC-MS analysis of the seeds' oil showed a high concentration of omega-3 fatty acid, with a percentage of 35.64% of the total fatty acid content in the seed oil. The biological results revealed that the dichloromethane fraction showed promising DPPH radical-scavenging activity (IC50 = 14.73 µg/mL), antidiabetic activity with significant inhibition of the α-amylase enzyme (IC50 673.25 μg/mL), and anti-inflammatory activity using in vitro histamine release assay (IC50 61.8 μg/mL). Furthermore, the dichloromethane fraction revealed moderate cytotoxic activity against human lung cancer cell line (A-549), human prostate carcinoma (PC-3), and colon carcinoma (HCT-116) with IC50s 35.9 ± 2.1 μg/mL, 42.4 ± 2.3 μg/mL, and 47.5 ± 1.3 μg/mL, respectively, and antiobesity activity with IC50 59.3 μg/mL, using pancreatic lipase inhibitory assay. In conclusion, this study's findings not only shed light on the phytochemical constituents and biological activities of the non-polar fractions of chia but also should be taken as a basis for the future in vivo and clinical studies on the safety and efficacy of chia and its extracts. Further study should be focused towards the isolation of the active principles of the dichloromethane fraction and studying their efficacy, exact mechanism(s), and safety, which could benefit the pharmaceutical industry and folk medicine practitioners who use this plant to cure diseases.

Abstract
Moringa oleifera, also known as the "tree of life" or "miracle tree," is classified as an important herbal plant due to its immense medicinal and non-medicinal benefits. Traditionally, the plant is used to cure wounds, pain, ulcers, liver disease, heart disease, cancer, and inflammation. This review aims to compile an analysis of worldwide research, pharmacological activities, phytochemical, toxicological, and ethnomedicinal updates of Moringa oleifera and also provide insight into its commercial and phytopharmaceutical applications with a motive to help further research. The scientific information on this plant was obtained from various sites and search engines such as Scopus, Pub Med, Science Direct, BMC, Google Scholar, and other scientific databases. Articles available in the English language have only been referred for review. The pharmacological studies confirm the hepatoprotective, cardioprotective, and anti-inflammatory potential of the extracts from the various plant parts. It was found that bioactive constituents are present in every part of the plant. So far, more than one hundred compounds from different parts of Moringa oleifera have been characterized, including alkaloids, flavonoids, anthraquinones, vitamins, glycosides, and terpenes. In addition, novel isolates such as muramoside A&B and niazimin A&B have been identified in the plant and have potent antioxidant, anticancer, antihypertensive, hepatoprotective, and nutritional effects. The traditional and nontraditional use of Moringa, its pharmacological effects and their phytopharmaceutical formulations, clinical studies, toxicity profile, and various other uses are recognized in the present review. However, several traditional uses have yet to be scientifically explored. Therefore, further studies are proposed to explore the mechanistic approach of the plant to identify and isolate active or synergistic compounds behind its therapeutic potential.

Abstract
Various functional groups were observed in the FTIR analysis of Hydnocarpus laurifolia seeds ethyl acetate extract such as O-H, N-H, C-H, -CH2, O=C=O, C=O, C=O-NH, and CH3, etc. Eleven bioactive compounds were detected via GC-MS and the predominant compounds include (1S)-2-cyclopentene-1-tridecanoicacid (chaulmoogric acid) (80.59%); 2-cyclopentene-1-undecanoic acid (hydnocarpic acid) (6.76%); cyclobutylamine (5.28%); methyl thioacetate (ethanethioic acid) (4.84%); lignoceric acid (2.21%). The TPC and TFC values were 0.110 ± 0.04 GAE g-1 and 0.175 ± 0.05 g CE g-1 respectively. Ethyl acetate extract showed strong DDPH free radical scavenging activity with IC50 value 10.64 ± 0.48 µg ml-1 and antioxidant activity index 3.759. The ethyl acetate extract also exhibited potential ABTS radical scavenging efficacy with a very low IC50 value, i.e., 07.81 ± 0.48 µg ml-1. P. aeruginosa was the most sensitive bacteria to the extract with 33.16 ± 0.88 mm inhibition zone and MIC: 3.12 mg ml-1, MBC: 6.25 mg ml-1. P. aeruginosa biofilm was inhibited by ethyl acetate extract 99.22% at MIC concentration. The LM images displayed a decrease in the number of biofilm cells and FE-SEM micrographs showcased the extensive decrease as well as disintegration in biofilm. Additionally, ethyl acetate extract was found selectively cytotoxic to the K562 cancer cells having an IC50 of 25.41 μg ml-1 and barely cytotoxic to normal PBMCs having an IC50 of 482.54 μg ml-1, and the selectivity index value was 18.99. Data validate scientifically the traditional use of H. laurifolia seeds in folk medicines and confirmed that it can be used in modern phytomedicines as an antioxidant, antimicrobial, antibiofilm, and anticancer agent and is toxicologically safe.

Abstract
This study presents a comparison between two mistletoe plants—P. acacia and P. curviflorus—regarding their total phenolic contents and antioxidant and anticancer activities. P. curviflorus exhibited a higher total phenolics content (340.62 ± 19.46 mg GAE/g extract), and demonstrated higher DPPH free radical scavenging activity (IC50 = 48.28 ± 3.41µg/mL), stronger reducing power (1.43 ± 0.54 mMol Fe+2/g) for ferric ions, and a greater total antioxidant capacity (41.89 ± 3.15 mg GAE/g) compared to P. acacia. The cytotoxic effects of P. acacia and P. curviflorus methanol extracts were examined on lung (A549), prostate (PC-3), ovarian (A2780) and breast (MDA-MB-231) cancer cells. The highest anticancer potential for the two extracts was observed on PC-3 prostate cancer cells, where P. curviflorus exhibited more pronounced antiproliferative activity (IC50 = 25.83 μg/mL) than P. acacia (IC50 = 34.12 μg/mL). In addition, both of the tested extracts arrested the cell cycle at the Pre-G1 and G1 phases, and induced apoptosis. However, P. curviflorus extract possessed the highest apoptotic effect, mediated by the upregulation of p53, Bax, and caspase-3, 8 and 9, and the downregulation of Bcl-2 expression. In the pursuit to link the chemical diversity of P. curviflorus with the exhibited bioactivities, its metabolomic profiling was achieved by the LC-ESI-TOF-MS/MS technique. This permitted the tentative identification of several phenolics—chiefly flavonoid derivatives, beside some triterpenes and sterols—in the P. curviflorus extract. Furthermore, all of the metabolites in P. curviflorus and P. acacia were inspected for their binding modes towards both CDK-2 and EGFR proteins using molecular docking studies in an attempt to understand the superiority of P. curviflorus over P. acacia regarding their antiproliferative effect on PC-3 cancer cells. Docking studies supported our experimental results; with all of this taken together, P. curviflorus could be regarded as a potential prospect for the development of chemotherapeutics for prostate cancer.

Afifi SM, Ammar NM, Kamel R, Esatbeyoglu T, Hassan HA. β-Sitosterol Glucoside-Loaded Nanosystem Ameliorates Insulin Resistance and Oxidative Stress in Streptozotocin-Induced Diabetic Rats. Antioxidants (Basel) 2022; 11:1023. [PMID: 35624887 PMCID: PMC9137832 DOI: 10.3390/antiox11051023] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 05/18/2022] [Accepted: 05/19/2022] [Indexed: 12/16/2022] Open
Abstract
β-Sitosterol glucoside (SG), isolated from Senecio petasitis (Family Asteraceae), was loaded in self-nanoemulsifying drug delivery systems (SEDDS) in a trial to enhance its solubility and biological effect. Various co-surfactants were tested to prepare a successful SEDDS. The selected SG-loaded SEDDS had a droplet size of 134 ± 15.2 nm with a homogenous distribution (polydispersity index 0.296 ± 0.02). It also demonstrated a significant augmentation of SG in vitro release by 4-fold compared to the free drug suspension. The in vivo insulin sensitivity and antidiabetic effect of the prepared SG-loaded SEDDS were further assessed in streptozotocin-induced hyperglycemic rats. The hypoglycemic effect of SG-loaded nanosystem was evidenced by decreased serum glucose and insulin by 63.22% and 53.11%, respectively. Homeostasis model assessment-insulin resistance (HOMA-IR) index demonstrated a significant reduction by 5.4-fold in the diabetic group treated by SG-loaded nanosystem and exhibited reduced glucagon level by 40.85%. In addition, treatment with SG-loaded nanosystem significantly decreased serum MDA (malondialdehyde) and increased catalase levels by 38.31% and 64.45%, respectively. Histopathological investigations also supported the protective effect of SG-loaded nanosystem on the pancreas. The promising ability of SG-loaded nanosystem to ameliorate insulin resistance, protect against oxidative stress, and restore pancreatic β-cell secretory function warrants its inclusion in further studies during diabetes progression.

Hunting Bioactive Molecules from the Agave Genus: An Update on Extraction and Biological Potential. Molecules 2021; 26:molecules26226789. [PMID: 34833879 PMCID: PMC8618589 DOI: 10.3390/molecules26226789] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 11/02/2021] [Accepted: 11/05/2021] [Indexed: 11/26/2022] Open
Abstract
Agaves are plants used in the production of alcoholic beverages and fibers. Ever since ancient times, pre-Hispanic cultures in Mexico have used them in traditional medicine to cure different ailments. Over the years, studies of the active principles responsible for the therapeutic benefits of agaves have increased. Leaves and fibers are the main agro-wastes generated in tequila and mezcal production, while fibers are the main waste product in the textile sector. Different investigations have referred to the agro-waste from agave processing as a source of bioactive molecules called secondary metabolites (SM). Among them, phenols, flavonoids, phytosterols, and saponins have been extracted, identified, and isolated from these plants. The role of these molecules in pest control and the prospect of metabolites with the biological potential to develop novel drugs for chronic and acute diseases represent new opportunities to add value to these agro-wastes. This review aims to update the biological activities and recent applications of the secondary metabolites of the genus Agave.

Abstract
Agave, commonly known as “maguey” is an important part of the Mexican tradition and economy, and is mainly used for the production of alcoholic beverages, such as tequila. Industrial exploitation generates by-products, including leaves, bagasse, and fibers, that can be re-valorized. Agave is composed of cellulose, hemicellulose, lignin, fructans, and pectin, as well as simple carbohydrates. Regarding functional properties, fructans content makes agave a potential source of prebiotics with the capability to lower blood glucose and enhance lipid homeostasis when it is incorporated as a prebiotic ingredient in cookies and granola bars. Agave also has phytochemicals, such as saponins and flavonoids, conferring anti-inflammatory, antioxidant, antimicrobial, and anticancer properties, among other benefits. Agave fibers are used for polymer-based composite reinforcement and elaboration, due to their thermo-mechanical properties. Agave bagasse is considered a promising biofuel feedstock, attributed to its high-water efficiency and biomass productivity, as well as its high carbohydrate content. The optimization of physical and chemical pretreatments, enzymatic saccharification and fermentation are key for biofuel production. Emerging technologies, such as ultrasound, can provide an alternative to current pretreatment processes. In conclusion, agaves are a rich source of by-products with a wide range of potential industrial applications, therefore novel processing methods are being explored for a sustainable re-valorization of these residues.
