Abstract
Medicinal plants have been used since prehistoric times and continue to treat several diseases as a fundamental part of the healing process. Inflammation is a condition characterized by redness, pain, and swelling. This process is a hard response by living tissue to any injury. Furthermore, inflammation is produced by various diseases such as rheumatic and immune-mediated conditions, cancer, cardiovascular diseases, obesity, and diabetes. Hence, anti-inflammatory-based treatments could emerge as a novel and exciting approach to treating these diseases. Medicinal plants and their secondary metabolites are known for their anti-inflammatory properties, and this review introduces various native Chilean plants whose anti-inflammatory effects have been evaluated in experimental studies. Fragaria chiloensis, Ugni molinae, Buddleja globosa, Aristotelia chilensis, Berberis microphylla, and Quillaja saponaria are some native species analyzed in this review. Since inflammation treatment is not a one-dimensional solution, this review seeks a multidimensional therapeutic approach to inflammation with plant extracts based on scientific and ancestral knowledge.

Effect of brewing time and temperature on the physical properties, antioxidant activities and sensory of the kenaf leaves tea. JOURNAL OF FOOD SCIENCE AND TECHNOLOGY 2022; 59:510-517. [PMID: 35185172 PMCID: PMC8814219 DOI: 10.1007/s13197-021-05034-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Revised: 01/29/2021] [Accepted: 02/16/2021] [Indexed: 02/03/2023]
Abstract
Kenaf (Hibiscus cannabinus L.), an annual herbaceous plant in the Malvaceae family, has become a multifunctional crop in Malaysia due to its large number of industrial applications for its fibrous stem. Recently, its kenaf leaves that have high antioxidant properties are getting more attention to be developed into tea. Therefore, this research aims to determine the best brewing time and temperature based on the physical properties, antioxidant activities and sensory of kenaf leaves tea (KLT). The kenaf leaves powder which was infused in hot (80 °C or 100 °C; 5 min or 10 min) or cold water (room temperature; 60 min or 120 min) were analysed. Results demonstrated that the KLT brewed at 80 °C for 10 min and 100 °C for 10 min showed the highest antioxidant activities in most of the antioxidant analysis conducted. Moreover, the colour of cold-brewed KLT was much lighter than the hot-brewed KLT and the cold-brewed KLT (room temperature; 120 min) can likely be a new trend for the consumer since it contained high antioxidising capabilities. However, the pH, greenness, yellowness, sensory results in KLT were not affected significantly by both brewing time and temperature (p > 0.05). The antioxidant test was correlated positively with the phytochemical contents but insignificant relationship with most of the colour parameters. Overall, the optimum temperature and time for brewing KLT was 80 °C at 10 min because it saved energy and extracted the highest amount of antioxidants while retaining similar sensory taste with other brewing conditions.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fabiana imbricata (Solanaceae) is a Patagonian medicinal plant with a long tradition of use. The aim of this review is to provide an integrative overview of the traditional uses, chemistry, bioactivity and chemical profiling of the crude drug. MATERIALS AND METHODS The information was collected from scientific databases searching with the keywords Fabiana imbricata, Fabiana species, Fabiana (Solanaceae) and includes local literature and books. RESULTS The indications of use reported in literature show little variation from the data published as early as 1889. The chemical studies showed a rich diversity in metabolites including phenolics, coumarins, flavonoids, phenylpropanoids, terpenes, alkaloids and sugars. Bioactivity studies supported the traditional use as diuretic and also the potential of the crude drug as a gastroprotective agent. The plant can be used as a source of compounds with effect on gastric ulcers and shows enzyme inhibitory activity. While the germination rate of the plant is very low, protocols were developed for the rapid in vitro propagation of the species. The toxicity of the crude drug extracts was low and did not show clastogenic effect in human lymphocytes. Further research is needed to disclose the potential of the F. imbricata sesquiterpenes on other relevant biological targets.

Abstract
Acetophenones are phenolic metabolites of plant species. A metabolic route for the biosynthesis and release of 2 defence-related hydroxyacetophenones in white spruce (Picea glauca) was recently proposed to involve 3 phases: (a) biosynthesis of the acetophenone aglycons catalysed by a currently unknown set of enzymes, (b) formation and accumulation of the corresponding glycosides catalysed by a glucosyltransferase, and (c) release of the aglycons catalysed by a glucosylhydrolase (PgβGLU-1). We tested if this biosynthetic model is conserved across Pinaceae and land plant species. We assayed and surveyed the literature and sequence databases for possible patterns of the presence of the acetophenone aglycons piceol and pungenol and their glucosides, as well as sequences and expression of Pgβglu-1 orthologues. In the Pinaceae, the 3 phases of the biosynthetic model are present and differences in expression of Pgβglu-1 gene orthologues explain some of the interspecific variation in hydroxyacetophenones. The phylogenetic signal in the metabolite phenotypes was low across species of 6 plant divisions. Putative orthologues of PgβGLU-1 do not form a monophyletic group in species producing hydroxyacetophenones. The biosynthetic model for acetophenones appears to be conserved across Pinaceae, whereas convergent evolution has led to the production of acetophenone glucosides across land plants.

Abstract
The present study was undertaken to investigate the diuretic activity and acute toxicity profile of the crude aqueous extract and solvent fraction of the leaves of Thymus serrulatus in saline-loaded Swiss albino mice. Mice of either sex were divided into six groups (five animals in each group). The control group received normal saline (25 mL/kg), while the reference group received hydrochlorothiazide (10 mg/kg). Group III to Group VI received the test substances at dose levels of 125, 250, 500, and 1,000 mg/kg orally, respectively. At the end of the fifth hour, urine was collected, and total volume of urine excreted by each animal was recorded. Concentrations of urinary Na+ and K+ were determined, and the Na+/K+ ratio was calculated to make comparison among the groups. The acute toxicity of the most active fraction was also evaluated. The findings demonstrated that the crude aqueous extract of T. serrulatus leaves showed significant diuretic (P<0.01), natriuretic (P<0.01), and kaliuretic (P<0.01) effects. At the dose of 1,000 mg/kg, the n-butanol fraction demonstrated the highest diuretic activity comparable to the reference drug. It also showed a good natriuretic activity. The dichloromethane fraction, however, did not have significant diuretic activity. Both the crude aqueous extract of the leaves of T. serrulatus and its n-butanol fraction have diuretic activity with high concentration of urinary electrolytes in mice. Further studies, however, need to be pursued on the possible mechanism(s) of diuretic action.

Abstract
Opuntia flowers are a natural source of biologically active compounds and they have been used as medicinal plant for a long time. Despite the various uses reported for the decoction and infusion of these flowers, their characterization has been discarded. In this study, the decoction and infusion prepared from Opuntia ficus-indica were analyzed with respect to their content in minerals and phytochemicals in order to evaluate its nutritional characteristics. The obtained data proved that these preparations are a rich source of minerals mainly K and Ca. Moreover, the phytochemical analysis revealed that they have important polyphenols, flavonoids and tannins contents with the infusion that presented the highest polyphenol levels. LC-MS analyses of decoction and infusion allowed the characterization of 20 phenolic compounds. It is mainly identified by the presence of flavonols glycosides.

Abstract
This study evaluated the application of ultrasound techniques and microwave energy, compared to conventional extraction methods (high temperatures at atmospheric pressure), for the solid-liquid extraction of steviol glycosides (sweeteners) and antioxidants (total phenols, flavonoids and antioxidant capacity) from dehydrated Stevia leaves. Different temperatures (from 50 to 100 °C), times (from 1 to 40 min) and microwave powers (1.98 and 3.30 W/g extract) were used. There was a great difference in the resulting yields according to the treatments applied. Steviol glycosides and antioxidants were negatively correlated; therefore, there is no single treatment suitable for obtaining the highest yield in both groups of compounds simultaneously. The greatest yield of steviol glycosides was obtained with microwave energy (3.30 W/g extract, 2 min), whereas, the conventional method (90 °C, 1 min) was the most suitable for antioxidant extraction. Consequently, the best process depends on the subsequent use (sweetener or antioxidant) of the aqueous extract of Stevia leaves.

Abstract
Changes in the contents and composition of polyphenolics and resulting antioxidant activities of S. verbenaca by-products were investigated at three phenological stages (flowering, early fruiting and late fruiting stages). The highest accumulation of total phenolics was detected at the flowering stage (58.36 mg GAE/g DW). HPLC analysis of methanolic extracts showed the prevalence of methyl carnosate (821.45-919.82 μg/g DW) and rosmarinic acid (544.51-649.26 μg/g DW). Phenolic diterpenes (1056.90-1148.42 μg/g DW) was the most represented class of compounds. Three complementary tests namely, DPPH(•) (IC50 value, 49.22 μg/mL) and ABTS(•+)-radical scavenging assays (146.86 μM TE/mg) and FRAP reducing power test (188.93 mM Fe(II)/mg) were used to evaluate the antioxidant capacity and showed the best performance at the early fruiting period. The current study evidenced the significant effect of phenophase on antioxidants and contributed to valorize S. verbenaca extracts as a source of functional phenolic compounds.

Abstract
Oligonol is a low-molecular-weight polyphenol that possesses antioxidant and anti-inflammatory properties. This study investigated the effects of Oligonol supplementation on sweating response, plasma volume (PV), and osmolality (Osm) after heat load in human volunteers. We conducted a placebo-controlled crossover trial. Participants took a daily dose of 200 mg Oligonol or placebo for 1 week. After a 2-week washout period, the subjects were switched to the other study arm. As a heat load, half-body immersion into hot water (42°C±0.5°C for 30 min) was performed in an automated climate chamber. Tympanic and mean body temperature (Tty, mTb) and whole-body sweat loss volume (WBSLV) were measured. Changes in PV, Osm, and serum levels of aldosterone and sodium were analyzed. Oligonol intake attenuated increases in Tty, mTb, and WBSLV after heat load compared with the placebo (P<.01, P<.05, and P<.01, respectively). In addition, serum aldosterone was maintained at a relatively low degree and serum sodium was maintained at a relatively high degree with Oligonol compared to the placebo (P<.01 and P<.05, respectively). However, PV decreased and Osm increased significantly with Oligonol compared to the placebo (P<.05 and P<.05, respectively). This study demonstrates that Oligonol supplementation for 1 week can attenuate elevation of body temperature and excessive sweating under heat load in healthy humans, but interpretation of the results requires caution due to the potent diuretic effect of Oligonol.

Phenolic profiling of the South American "Baylahuen" tea (Haplopappus spp., Asteraceae) by HPLC-DAD-ESI-MS. Molecules 2015; 20:913-28. [PMID: 25580687 PMCID: PMC6272720 DOI: 10.3390/molecules20010913] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2014] [Accepted: 12/30/2014] [Indexed: 11/17/2022] Open
Abstract
The aerial parts of several Haplopappus species (Asteraceae), known under the common name "baylahuen", are used as herbal teas in Chile and Argentina. In Chile, "baylahuen" comprises H. multifolius, H. taeda, H. baylahuen and H. rigidus. Little is known about the chemical identity of the infusion constituents in spite of widespread consumption. The aim of the present work was the characterization of phenolics occurring in the infusions and methanol extracts of "baylahuen" by HPLC-DAD-ESI-MS. A simple HPLC-DAD-ESI-MS method was developed for the fast identification and differentiation of Haplopappus spp. used as a tea source, based on the phenolics from the tea and methanol extracts. Some 27 phenolics were tentatively identified in the infusions and methanol extract, including 10 caffeoyl quinic and feruloyl quinic acid derivatives and 17 flavonoids. The HPLC patterns of the Haplopappus tea and methanol extract allow a clear differentiation at the species level. The occurrence of hydroxycinnamic acid derivatives and flavonoids can explain the reputed nutraceutical and health beneficial properties of this herbal tea.

Abstract
The present study investigated the anti-oxidative and hepatoprotective effects of Glossogyne tenuifolia (GT) Cassini, against acetaminophen-induced acute liver injury in BALB/c mice. The extracts of GT by various solvents (hot water, 50% ethanol and 95% ethanol) were compared for their 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, reducing power, total phenolic content, and total anti-oxidant capacity. The results showed that hot water (HW) extracts of GT contained high levels of phenolics and exerted an excellent anti-oxidative capacity; thus, these were used in the animal experiment. The male BALB/c mice were randomly divided into control group, acetaminophen (APAP) group, positive control group and two GT groups at low (GT-L) and high (GT-H) dosages. The results showed that mice treated with GT had significantly decreased serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). GT-H increased glutathione levels and the ratios of reduced glutathione and oxidized glutathione (GSH/GSSG) in the liver, and inhibited serum and lipid peroxidation. This experiment was the first to determine phenolic compounds, chlorogenic acid and luteolin-7-glucoside in HW extract of GT. In conclusion, HW extract of GT may have potential anti-oxidant capacity and show hepatoprotective capacities in APAP-induced liver damaged mice.

Abstract
Eryngium bornmuelleri Nab. (Tusî) is an endemic botanical from the Eastern Anatolia region of Turkey traditionally used for preparation of herbal tea. Within this study, phenolic composition, antioxidant capacities and inhibitory activities towards selected digestive enzymes of E. bornmuelleri leaf were investigated. Sequential extracts, obtained by extraction of plant tissue by ethanol, acetone and water exhibited pronounced antioxidant capacities and in a dose-dependent manner suppressed the metabolic syndrome related enzymes: α-amylase, α-glucosidase and pancreatic lipase. All extracts contained high levels of phenolic compounds. Flavonoid glycosides were the main phytochemicals detected, with rutin as the major compound (70% of total phenolics). Chlorogenic, hydroxybenzoic and caftaric acids as well as traces of caffeic, ferulic and rosmarinic acids were also detected. Correlation analysis indicated that phenolic compounds were the major sources of the enzyme-inhibitory activities. This study suggests that E. bornmuelleri leaf extracts can modulate the metabolism of sugars and fats through inhibition of the relevant digestive enzymes.

Abstract
Stevia, a non-caloric natural sweetener with beneficial properties and considerable antioxidants and amino acids, is increasingly consumed as an infusion. This work evaluates the influence of the conditions (temperature: 50, 70 or 90 °C and time: 1, 5, 20 or 40 min) applied to obtain Stevia infusions, on antioxidants (total phenols, flavonoids and antioxidant activity) and amino acids. The total concentration of the eleven amino acids found was 11.70 mg/g in dried leaves and from 6.84 to 9.11 mg/g per gram of Stevia in infusions. However, infusions showed higher levels of certain amino acids (alanine, asparagine, leucine and proline), and greater values of the three antioxidant parameters in comparison with dry leaves. Temperature had more influence (minimum values at 50 °C and maximum at 90 °C) than time in the case of antioxidants. At 90 °C there were no important increases in the extraction of antioxidant compounds after 5 min; each gram of Stevia had 117 mg trolox (total antioxidant activity), 90 mg gallic acid (total phenols) and 56 mg catechin equivalents (flavonoids). Varying the temperature and time conditions no notable differences were observed in the concentrations of the majority of amino acids. However, the infusion treatment at 90 °C for 5 min was the best, as it gave the highest yield of 8 of the 11 amino acids. Therefore, with respect to the compounds analyzed in this study, the best way to obtain Stevia leaf infusions is the same as the domestic process, almost boiling water for a short time.
