Kim Y, Lee SB, Cho M, Choe S, Jang M. Indian Almond ( Terminalia catappa Linn.) Leaf Extract Extends Lifespan by Improving Lipid Metabolism and Antioxidant Activity Dependent on AMPK Signaling Pathway in Caenorhabditis elegans under High-Glucose-Diet Conditions. Antioxidants (Basel) 2023; 13:14. [PMID: 38275634 PMCID: PMC10812731 DOI: 10.3390/antiox13010014] [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: 10/24/2023] [Revised: 12/13/2023] [Accepted: 12/14/2023] [Indexed: 01/27/2024] Open
Abstract
This study aimed to evaluate the antioxidant and antiaging effects of Indian almond (Terminalia catappa Linn.) leaf extract (TCE) on high-glucose (GLU)-induced obese Caenorhabditis elegans. Since TCE contains high contents of flavonoids and phenolics, strong radical scavenging activity was confirmed in vitro. The stress-resistance effect of TCE was confirmed under thermal and oxidative stress conditions at nontoxic tested concentrations (6.25, 12.5, and 25 μg/mL). GLU at 2% caused lipid and reactive oxygen species (ROS) accumulation in C. elegans, and TCE inhibited lipid and ROS accumulation under both normal and 2% GLU conditions in a concentration-dependent manner. In addition, TCE proved to be effective in prolonging the lifespan of C. elegans under normal and 2% GLU conditions. The ROS reduction effect of TCE was abolished in mutants deficient in daf-16/FOXO and skn-1/Nrf-2. In addition, the lifespan-extending effect of TCE in these two mutants disappeared. The lifespan-extending effect was abolished even in atgl-1/ATGL-deficiency mutants. The TCE effect was reduced in aak-1/AMPK-deficient mutants and completely abolished under 2% GLU conditions. Therefore, the effect of prolonging lifespan by inhibiting lipid and ROS accumulation under the high GLU conditions of TCE is considered to be the result of atgl-1, daf-16, and skn-1 being downregulated by aak-1. These results suggest that the physiological potential of TCE contributes to antiaging under metabolic disorders.

Jang M, Choi SI. Schisandrin C isolated from Schisandra chinensis fruits inhibits lipid accumulation by regulating adipogenesis and lipolysis through AMPK signaling in 3T3-L1 adipocytes. J Food Biochem 2022; 46:e14454. [PMID: 36200699 DOI: 10.1111/jfbc.14454] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 09/05/2022] [Accepted: 09/16/2022] [Indexed: 01/14/2023]
Abstract
In this study, lignans of Schisandra chinensis fruits (SCF) were profiled using HPLC-MS/MS, and the inhibitory effects of nine of these lignans were evaluated on triglyceride (TG) accumulation. We then examined the effects and molecular mechanisms on adipogenesis and lipolysis of schisandrin C (SC), which most inhibited TG levels during adipogenesis of 3T3-L1 cells. Treatment of 3T3-L1 cells with SC markedly decreased adipocyte differentiation but did not influence cell proliferation. During adipogenesis, SC significantly reduced total lipid and TG contents and down-regulated the mRNA expressions of C/EBPα, PPARγ, SREBP1c, aP2, and FAS. In addition, SC significantly increased p-AMPK, and this activation regulated the protein levels of major adipogenic transcription factors (PPARγ and C/EBPα). Furthermore, SC lowered the mRNA expressions of HSL and perilipin and inhibited pancreatic lipase levels, which are both related to lipolysis. PRACTICAL APPLICATIONS: Our results indicate that SC regulates lipogenesis and lipolysis by increasing AMPK phosphorylation and suggest that it may be beneficial for preventing obesity and related metabolic diseases. Thus, this study proposes a mechanical basis for developing SC-containing foods as a beneficial dietary strategy.

Wei X, Zhao Z, Zhong R, Tan X. A comprehensive review of herbacetin: From chemistry to pharmacological activities. JOURNAL OF ETHNOPHARMACOLOGY 2021; 279:114356. [PMID: 34166735 DOI: 10.1016/j.jep.2021.114356] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Revised: 06/09/2021] [Accepted: 06/19/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Herbacetin is an active constituent of traditional Chinese medicines such as Ephedra sinica Stapf (MaHuang) and Sedum roseum (L.). Scop. (Hong JingTian). MaHuang was used to treat cough, asthma, fever, and edema for more than 5000 years, while Hong JingTian was used to treat depression, fatigue, cancers, and cardiovascular disease. Recent studies indicate that herbacetin and its glycosides play a critical role in the pharmacological activities of these herbs. However, currently, no comprehensive review on herbacetin has been published yet. AIM OF THE STUDY This review aimed to summarize information on the chemistry, natural sources, and pharmacokinetic features of herbacetin, with an emphasis on its pharmacological activities and possible mechanisms of action. MATERIALS AND METHODS A literature search was performed on the Web of Science, PubMed, and China Knowledge Resource Integrated databases (CNKI) using the search term "herbacetin" ("all fields") from 1935 to 2020. Information was also obtained from classic books of Chinese herbal medicine, Chinese pharmacopeia, and the database "The Plant List" (www.theplantlist.org). Studies have been analyzed and summarized in this review if they dealt with chemistry, taxonomy, pharmacokinetic, and pharmacological activity. RESULTS Herbacetin is distributed in various plants and can be extracted or synthesized. It showed diverse pharmacological activities including antioxidant, antiviral, anti-inflammatory, anticancer, antidiabetic, and anticholinesterase. It is thought to have great potential in cancer treatment, especially colon and skin cancers. However, the bioavailability of herbacetin is low and the toxicity of herbacetin has not been studied. Thus, more studies are required to solve these problems. CONCLUSIONS Herbacetin shows promising pharmacological activities against multiple diseases. Future research should focus on improving bioavailability, further studying its pharmacological mechanism, evaluating its toxicity and optimal dose, and performing the clinical assessment. We hope that the present review will serve as a guideline for future research on herbacetin.

Dillenia Indica Fruit Extract Suppressed Diet-induced Obesity in Rats by Down-regulating the mRNA Level of Proadipogenic Transcription Factors and Lipid Metabolizing Enzymes. CURRENT NUTRITION & FOOD SCIENCE 2021. [DOI: 10.2174/1573401316999200901173319] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/12/2023]
Abstract
Background:
Dillenia indica (Family: Dilleniaceae) is an antioxidant-rich edible fruitbearing
medicinal plant. The fruit of this plant (known as elephant apple) has many uses in traditional
medicine.
Objective:
By considering its antioxidant content and ameliorating effects, this study aimed to evaluate
the anti-adipogenic effects of D. indica fruit extract (DIFE) on high-fat diet (HFD) fed obese
rats.
Methods:
Male Wistar rats were fed with a standard diet (SD), or high-fat diet (HFD), or HFD
with 100 mg/kg or 200 mg/kg or 400 mg/kg DIFE for 8 weeks. The fruit extract was given orally
by feeding gavage. The body weight, liver weight, visceral fat weight, plasma lipids, and oxidative
stress-related parameters were measured. The mRNA level of different adipogenesis related transcription
factors, lipogenic and lipolytic enzymes was also evaluated.
Results:
Consumption of DIFE daily (400 mg/kg) for 8 weeks resulted in a significant reduction of
high-fat diet-induced body weight, liver weight, visceral fat weight, total cholesterol, and LDL-cholesterol
level. High-fat diet-mediated elevation of oxidative stress markers was also lowered,
with a parallel augmentation of the activities of antioxidant enzymes, due to 400 mg/kg DIFE feeding.
DIFE also down-regulated the mRNA level of important pro-adipogenic factors like PPARγ,
LXRα, and SREBP1c which consequently downregulated the transcript levels of lipogenic enzymes:
ACC, FAS, HMGCR, and DGAT. The transcript level of lipolytic enzyme, HSL was also
down-regulated in 400 mg/kg DIFE-fed rats.
Conclusion:
These findings indicate that the antioxidant-rich ethanolic extract of D. indica fruit
can down-regulate the gene expression of pro-adipogenic transcription factors and lipid metabolizing
enzymes and thus can suppress diet-induced obesity in Wistar rat.

Efficacy of a Novel Herbal Formulation (F2) on the Management of Obesity: In Vitro and In Vivo Study. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:8854915. [PMID: 33628322 PMCID: PMC7884115 DOI: 10.1155/2021/8854915] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Revised: 01/07/2021] [Accepted: 01/28/2021] [Indexed: 11/23/2022]
Abstract
Background Currently, obesity and its comorbidities have become a serious threat to human health necessitating urgent development of safe and effective therapy for their management. Materials and Methods In this research, a novel polyherbal formulation (F2) was prepared by mixing specific proportions of royal jelly and lemon juice with ethanol extracts of Orostachys japonicus, Rhus verniciflua, and Geranium thunbergii. The antioxidant activity was assessed using DPPH and ABTS assay methods. The antiobesity potential of the F2 was assessed in vitro using 3T3-L1 fibroblast and in vivo using a high-fat diet (HFD) fed C57BL/6J mice model. F2 was administered in mice at the dose of 23 mg/kg and 46 mg/kg, twice daily by oral gavage. A well-accepted antiobesity agent, Garcinia cambogia (GC), at 200 mg/kg was used as a positive control. Results F2 was observed to exhibit synergistic antiadipogenic activity in 3T3-L1 cells. This inhibition was reinforced by the downregulation of specific adipogenic transcription factors. Furthermore, F2 was also found to reduce mice body weight gain, food efficiency ratio, fasting blood glucose level, fat deposition into the liver, and mass of white adipose tissue. F2 also played a role in the excretion of fat consumed by the mice. For most of the assays performed, the F2 (46 mg/kg) was comparable to the positive control GC (200 mg/kg). In addition, potential and synergistic antioxidant activity was observed on F2. Conclusion The results revealed that the formulation F2 exhibited potential antiobesity activity through the inhibition of adipocyte differentiation, dietary fat absorption, and reduction of free fatty acids deposition in tissues.

Antioxidants (Basel) 2020; 9:antiox9030200. [PMID: 32121091 PMCID: PMC7139455 DOI: 10.3390/antiox9030200] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Revised: 02/20/2020] [Accepted: 02/21/2020] [Indexed: 12/12/2022] Open
Abstract
The aim of this study was, firstly, to evaluate the phenol profile of thistle (Cirsium japonicum, CJ) by High performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS), dried by different methods (90 °C hot-air, 70 °C hot-air, shade-, and freeze-drying). Secondly, we aimed to evaluate the relationship between phenolic compounds content and antioxidant properties. CJ contained chlorogenic acid, linarin, and pectolinarin. Total phenolic contents of CJ significantly decreased under hot-air-drying condition, especially chlorogenic acid contents in CJ have been reduced by 85% and 60% for 90 °C and 70 °C hot-air-drying, respectively. We evaluated the protective effect on adrenal pheochromocytoma (PC12) cells and Caenorhabditis elegans using shade-dried CJ, which has the largest phenolic contents and the strongest antioxidant property. CJ-treated PC 12 cells dose-dependently exhibited the protective effects against reactive oxygen species (ROS), while cell viability increases, lactate dehydrogenase release decreases, and ROS formation decreases. Furthermore, CJ has also shown protection against ROS in C. elegans. Consequently, CJ contributed to lifespan extension under ROS stress without influencing the physiological growth.

Orostachys japonicus ethanol extract inhibits 2,4-dinitrochlorobenzene-induced atopic dermatitis-like skin lesions in NC/Nga mice and TNF-α/IFN-γ-induced TARC expression in HaCaT cells. Toxicol Res 2019; 36:99-108. [PMID: 32257921 DOI: 10.1007/s43188-019-00026-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2019] [Revised: 10/02/2019] [Accepted: 10/09/2019] [Indexed: 01/10/2023] Open
Abstract
The risk of atopic dermatitis (AD)-like skin lesions has increased due to the elevated levels of allergens worldwide. Natural-origin agents, which are effective and safe, show promise for the prevention and treatment of inflammatory conditions. Orostachys japonicus (OJ) A. Berger is an ingredient of traditional herbal medicines for fever, gingivitis, and cancer in Korea, China, and Japan. However, the effect of OJ on AD-like skin lesions is unknown. Therefore, we investigated the effect of OJ ethanol extract (OJEE) on AD-like skin symptoms in mice and cells. OJEE reduced the 2,4-dinitrochlorobenzene-induced AD severity, serum levels of IgE and TARC, and mRNA levels of TARC, TNF-α, and IL-4 in NC/Nga mice. Histopathological analysis showed that OJEE reduced the thickness of the epidermis/dermis and dermal infiltration of inflammatory cells in ear tissue. Furthermore, OJEE suppressed the TNF-α/IFN-γ-increased TARC mRNA level by inhibiting NF-κB and STAT1 activation in HaCaT cells. Taken together, our findings show that OJEE reduced the risk of AD-like skin symptoms by decreasing TARC expression via inhibiting NF-κB and STAT1 activation in skin keratinocytes and thus shows promise as an alternative therapy for AD-like skin lesions.
