Abstract
Hangovers are uncomfortable physiological symptoms after alcohol consumption caused by acetaldehyde, a toxic substance in which alcohol is metabolized by alcohol dehydrogenase (ADH). Rapid alcohol and acetaldehyde decomposition are essential to alleviate alcohol handling symptoms. This study investigated the effects of HY_IPA combined with Mesembryanthemum crystallinum, Pueraria lobata flower, and Artemisia indica on alleviating hangovers. A randomized, double-blind, parallel-group, placebo-controlled clinical study was conducted on 80 individuals with hangover symptoms. Alcohol intake was 0.9 g/bw with 40% whiskey, adjusted proportionately to body weight. The Acute Hangover Scale total score was 5.24 ± 5.78 and 18.54 ± 18.50 in the HY_ IPA and placebo groups, respectively (p < 0.0001). All nine indicators of the hangover symptom questionnaire were significantly improved in the HY_IPA group (p < 0.01). Blood alcohol and acetaldehyde concentrations rapidly decreased from 30 min in the HY_IPA group (p < 0.05). ADH and acetaldehyde dehydrogenase (ALDH) activities in the blood of the HY_IPA group were significantly higher than those in the placebo group at 0, 1, and 2 h after alcohol consumption (p < 0.01). The rapid hangover relief was due to increased ADH and ALDH. Therefore, HY_IPA effectively relieves hangover symptoms by decomposing alcohol and acetaldehyde when consumed before alcohol consumption.

[PMID: 36621660 DOI: 10.1016/j.jep.2022.116089] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/10/2022] [Revised: 11/23/2022] [Accepted: 12/20/2022] [Indexed: 06/17/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pueraria Flos (PF), a traditional herbal medicine, is botanically from the dried flowers of Pueraria lobate (Willd.) Ohwi. (Chinese: ) or Pueraria thomsonii Benth. (Chinese: ). It has a long history of thousands of years in China for awakening the spleen, clearing the lungs, relieving alcohol. AIM OF THE REVIEW This review aims to report the up-to-date research progress in ethnopharmacology, phytochemistry, pharmacology and toxicology, metabolism and therapeutic application of PF, so as to provide a strong basis for future clinical treatment and scientific research. MATERIALS AND METHODS Relevant information on PF was collected from scientific literature databases including PubMed, CNKI and other literature sources (Ph.D. and M.Sc. dissertations and Chinese herbal classic books) by using the keyword "Puerariae". RESULTS Briefly, phytochemical research report has isolated 39 flavonoids, 19 saponins and 25 volatile oils from PF. Flavonoids and saponins are the most important bioactive compounds, and most of the quality control studies focus on these two types of compounds. Modern pharmacological studies have revealed their significant biological activities in relieving alcoholism, hepatoprotective, anti-tumor, anti-inflammatory, and anti-oxidation, which provides theoretical support for the traditional use. CONCLUSIONS Comprehensive analysis showed that pharmacological activity of most purified compounds from PF had not been reported. Kakkalide, tectoridin and their deglycosylated metabolites (irisolidone and tectorigenin) has been focused on excessively due to their higher content and better activities. This leads to low development and resources waste. Interestingly, PF made a breakthrough in the field of food. Many kinds of fat-lowering foods such as PILLBOX Onaka have been popular in Japan market, which received extensive attention. Therefore, we suggest that future research can be paid attention on the development of the plant's function in the field of food and medicine, as well as the transformation from experimental to clinical.

Abstract
Numerous prescribed drugs and herbal and dietary supplements have been reported to cause drug-induced acute liver injury, which is a frequent cause of acute liver failure (ALF). It is a tremendous challenge with ever-increasing drug application in the medication system for huge populations. Drug-induced acute liver injury can lead to diverse pathologies similar to acute and chronic hepatitis, acute liver failure, biliary obstruction, fatty liver disease, and so on. Recently, extensive work demonstrated that isoflavones play an essential and protecting role in drug-induced liver injury (DILI). The isoflavones mediated hepatoprotection by modulating specific genes linked with control of cellular redox homeostasis and inflammatory responses. Isoflavones upregulate oxidative stress-responsive nuclear factor erythroid 2-like 2 (Nrf2), downregulate inflammatory nuclear factor-κB (NF-κB) signaling pathways, and modulate a balance between cell survival and death. Moreover, isoflavones actively inhibit the expression of cytochromes P450 (CYPs) enzyme during drug metabolism. Moreover, isoflavones are also linked with farnesoid X receptor (FXR) activation and signal transducer and activator of transcription factor 3 (STAT3) phosphorylation in hepatoprotection DILI. In vivo and in vitro studies clearly stated that isoflavones bear strong antioxidant potential and promising agents for hepatotoxicity prevention and stressed their potential role as therapeutic supplements in DILI. The current review will elaborate on isoflavones’ preventive and therapeutic potential concisely and highlight various molecular targets to exert a protective effect on DILI.

Abstract
BACKGROUND Kakkalide is the predominant isoflavone derived from the flowers of Pueraria lobata (Willd.) Ohwi. The aim of the present study was to investigate the effects of kakkalide on insulin resistance in the endothelium. METHODS Human umbilical vein endothelial cells (HUVEC) were stimulated with 100 μmol/L palmitate (PA) for 30 min and the effects of 30 min pretreatment with 0.1-10 μmol/L kakkalide on reactive oxygen species (ROS)-associated inflammation in cells were evaluated by western blot analysis and reverse transcription-polymerase chain reaction. Furthermore, we investigated the biomodulation of insulin signaling by kakkalide along the insulin receptor substrate (IRS)-1/Akt/endothelial nitric oxide synthase (eNOS) pathway. We also determined the effects of 30 min pretreatment with 0.1-10 μmol/L kakkalide on insulin-mediated endothelium-dependent vasodilation of rat aorta in vitro following stimulation with 100 μmol/L PA. RESULTS Kakkalide inhibited ROS overproduction and effectively restored mitochondrial membrane potential, demonstrating its chemoprotection of mitochondrial function. In addition, kakkalide inhibited ROS-associated inflammation in the endothelium by inhibiting tumor necrosis factor-α and interleukin-6 production and gene expression, as well as suppressing the phosphorylation of c-Jun N-terminal kinase and IκB kinase β/nuclear factor-κB. Inflammation impaired insulin phosphatidylinositol 3-kinase (PI3K) signaling and reduced insulin-mediated NO production in endothelial cells. Kakkalide facilitated PI3K signaling by positively regulating serine/tyrosine phosphorylation of IRS-1. CONCLUSIONS Kakkalide inhibited ROS-associated inflammation and ameliorated insulin-resistant endothelial dysfunction by beneficial effects on IRS-1 function.

Abstract
Kudzu, a leguminous plant, has long been used in folk medicine. In particular, its flowers are used in Japanese and Chinese folk medicine for treating hangovers. We focused on the flower of Kudzu (Puerariae thomsonii), and we previously reported the antiobesity effect of Puerariae thomsonii flower extract (PFE) in humans. In this study, we conducted an animal study to investigate the effect of PFE on visceral fat and hepatic lipid levels in mice with diet-induced obesity. In addition, we focused on gene expression profiles to investigate the antiobesity mechanism of PFE. Male C57BL/6J mice were fed a high-fat diet (HFD) or an HFD supplemented with 5% PFE for 14 days. PFE supplementation significantly reduced body weight and white adipose tissue (WAT) weight. Moreover, in the histological analysis, PFE supplementation improved fatty liver. Hepatic reverse transcription-polymerase chain reaction revealed that PFE supplementation downregulated acetyl-CoA carboxylase expression. For adipose tissue, the expressions of hormone-sensitive lipase in WAT and uncoupling protein 1 in brown adipose tissue (BAT) were significantly upregulated. These results suggest that PFE exerts antiobesity and antifatty liver effects in high-fat diet-induced obese mice through suppressing lipogenesis in the liver, stimulating lipolysis in WAT, and promoting thermogenesis in BAT.

Abstract
The isolation and characterization of rat lens aldose reductase inhibitors from the Viola hondoensis W. Becker et H Boss were conducted. The extracts and organic fractions from V. hondoensis were tested. The MeOH extract and EtOAc fraction were found to exhibit potent rat lens aldose reductase inhibition in vitro, their IC50being 1.2 and 0.6 μg/ml, respectively. One major isoflavonoid glycoside was isolated from the ethyl acetate soluble fraction of V. hondoensis. Kakkalide was found to be the potential rat lens aldose reductase inhibitor (IC50= 0.34 μg/ml), and may be useful for the prevention and/or treatment of diabetic complications.

Abstract
Isoflavones contained in the root and flower of Kudzu (Pueraria lobata and related species) are suggested to be the critical component for its effects. Although metabolism of soy isoflavones has been well studied, the composition of isoflavones found in Kudzu is completely different from that of soy isoflavones. In the present study, we investigated whether isoflavones found in the flower of Pueraria thomsonii, a species of Kudzu, were metabolized by human fecal microbiota and murine small intestinal enzymes. Among 5 glycosidic isoflavones of the Pueraria thomsonii flower, tectorigenin 7-O-xylosylglucoside, tectoridin, genistin and glycitin were completely hydrolyzed by a homogenate of germfree mouse small intestine without contribution of bacteria. Released aglycones were not further metabolized, except that up to half of glycitein disappeared. Mouse small intestinal enzymes did not metabolize 6-hydroxygenistein 6,7-di-O-glucoside. Isoflavone aglycones as well as 6-hydroxygenistein 6,7-di-O-glucoside were highly metabolized by most of the human fecal suspensions. Metabolites were not detected with the present analytical methods in most cases. Although further investigations of the pharmacokinetics of Pueraria thomsonii flower isoflavones are needed, the results of the present study indicate active metabolism of Pueraria thomsonii flower isoflavones in the human intestine.

Abstract
Microglial activation plays an important role in alcohol-induced neuroinflammation. In search for natural medicines that may be of therapeutic potential for alcoholism, two new natural isoflavone glycosides, 6-hydroxybiochanin A-6,7-di-O-beta-d-glucopyranoside (1) and 6-hydroxygenistein-7-O-beta-d-glucopyranoside (2), were isolated from the ethanolic extract of the flowers of Pueraria thomsonii Benth., together with the seven known isoflavones, genistein (3), tectorigenin (4), irisolidone (5), genistin (7), tectoridin (8), tectorigenin-7-O-beta-d-xylosyl-(1 --> 6)-beta-d-glucopyranoside (9), and 6-hydroxygenistein-6,7-di-O-beta-d-glucopyranoside (11). Moreover, gehuain (6) and kakkalide (10) were obtained from the flowers of Pueraria lobata (Willd.) Ohwi. The structures of the new compounds were elucidated by UV, IR, HR-MS, and 1D and 2D NMR spectroscopic methods. Compounds 3-5 substantially inhibited the lipopolysaccharide-induced nitric oxide release from primary cultured rat cortical microglia (IC50: 1.3-9.3 microM). The inhibitory effects of compounds 6, 8, 9, and 11 (IC50: 38-62 microM) were significant but weaker than the above aglycones. However, compounds 1, 2, 7, and 10 showed little inhibitory activity. With regard to the structure-activity relationships of the isoflavonoids for the inhibition of microglial activation, the glycosylation at the C-7 hydroxyl group reduces the inhibitory activity. The methoxylation of 4'-hydroxyl group of 7-glycosylated isoflavonoids reduces the inhibitory activity, while the methoxyl group at the 6-position enhances the activity. The results suggest that isoflavonoids of Pueraria flowers may be of therapeutic potential in alcoholism related to microglial activation.

Abstract
The flowers from Pueraria, which are called Puerariae Flos, have been used since ancient times for recovery from alcohol intoxication. We elucidated the microbial transformation of the main isoflavones (1, 1a and 2) by using 29 commercially available human intestinal bacterial strains together with the bioactivation of the hepatoprotective activity of their metabolites. Tectoridin (1a), which contains only one glucosyl moiety, was metabolized to its aglycone 1b by various bacterial strains. On the other hand, the metabolism of 1 and 2, which both have disaccharide groups, was limited to specific bacterial strains. The metabolites 1c and 2c obtained from the Peptostreptococcus productus strain were completely different from those produced by the other strains. These metabolites were identified as 6-hydroxygenistein and 6-hydroxybiochanin A, respectively. The glycosides 1, 1a and 2 did not show any hepatoprotective activity, whereas aglycones 1b and 2b showed moderate activity. Furthermore, the hepatoprotective activity of the demethylated metabolites 1c and 2c was extremely potent. Although not all people have P. productus in their gastrointestinal tract, the O-demethylated compounds might become one of the bioactivated metabolites when Puerariae Flos is administered orally.

Abstract
To find out the active principles against ethanol-induced toxicity in mice, Andrographis paniculata Nees. (Ap) was chosen and isolated andrographolide (ANDRO) and arabinogalactan proteins (AGPs). ANDRO was detected by HPTLC, FTIR and quantified by HPLC (10mg/g of Ap powder). AGPs was detected by beta-glucosyl Yariv staining of SDS-PAGE gel, FTIR and quantified by single radial gel diffusion assay with beta-glucosyl Yariv reagent (0.5mg/g Ap powder). The mice are pretreated intra-peritoneally (i.p.) with different doses (62.5, 125, 250, and 500mg/kg) of body weight of mice] of ANDRO and AGPs for 7 days and then ethanol (7.5g/kg of body weight) was injected, i.p. Besides, silymarin was used as standard hepatoprotective agent for comparative study with ANDRO and AGPs. The ameliorative activity of ANDRO and AGP against hepatic renal alcohol toxicity was measured by assessing GOT, GPT, ACP, ALP and LP levels in liver and kidney. It has been observed that pretreatment of mice with ANDRO and AGPs at 500mg/kg of body weight and 125mg/kg of body weight respectively could able to minimize the toxicity in compare to ethanol treated group as revealed by the different enzymatic assay in liver and kidney tissues and the results were comparable with silymarin. Hence, out of several ill-defined compounds present in Ap, ANDRO and AGPs are the potential bioactive compounds responsible for protection against ethanol-induced toxicity.

Abstract
Alcoholism is a serious problem throughout the world. The development of alcoholism remedies have medical, social and economical significance. In view of the pitfalls of psychological dependence and adverse behavioural effects of synthetic drugs, the development of low toxicity and high efficiency medicines derived from natural products exhibits expansive market prospects. Based on these considerations, we summarize briefly folk application of traditional hangover remedies and clinical application of herbal complex and patent medicines for alcoholism treatment. We have reviewed the effects of natural medicines on intake, absorption and metabolism of alcohol, as well as the protective effects on alcohol-induced acute and chronic tissue injury.

Abstract
To clarify the hepatoprotective effects of kakkalide and its metabolite irisolidone by human fecal microflora, their effects on tert-butyl hydroperoxide (t-BHP)-injured HepG2 cells and mice were investigated. Irisolidone protected HepG2 cells against cytotoxicity induced by t-BHP. However, kakkalide did not protect cytotoxicity. When kakkalide 100 mg/kg was orally administered to mice injured by t-BHP, it significantly inhibited the increase in plasma alanine aminotransferase and aspartate aminotransferase activities by 84% and 85% of t-BHP-treated control group, respectively. The inhibitory effect of kakkalide is much more potent than that of silybin, a hepatoprotective agent. However, intraperitoneally administered kakkalide did not exhibit hepatoprotective activity. When irisolidone was intraperitoneally administered to mice, it exhibited potent hepatoprotective activity. Based on these findings, irisolidone can be hepatoprotective and kakkalide may be a prodrug transformed to irisolidone.

Abstract
A new 12a-dehydrorotenoid 1, 11-dihydroxy-9, 10-methylenedioxy-12a-dehydrorotenoid (1), together with a new isoflavonoid glycoside tectorigenin-7-O-beta-glucosyl-4'-O-beta-glucoside (3), were isolated and identified from the rhizomes of I. spuria (Zeal). In addition, 4 known compounds, tectorigenin (2) tectorigenin-7-O-beta-glucosyl (1 --> 6) glucoside (4), tectoridin (a tectorigenin-7-O-beta-glucoside) (5) and tectorigenin-4'-O-beta-glucoside (6) were isolated and identified for the first time from this plant. The structures of the isolated compounds were determined by spectroscopic methods (UV, IR, 1H, 13C-NMR, DEPT, HMQC, NOESY, and HMBC experiments and MS spectrometry) and by comparison with literature data of known compounds. Compounds 2, 4, 5, and 6 are reported for the first time from this plant through the present study.

Abstract
When kakkalide, which was isolated from Flos Puerariae, was incubated with human fecal bacteria, kakkalide was metabolized to irisolidone via kakkalidone. When kakkalide (250 mg/kg) was orally administered to rats, irisolidone, but not kakkalide, was detected in the blood. The mortality associated with ethanol treatment was slightly reduced when the mice were intraperitoneally treated with kakkalide. Intraperitoneally administered kakkalide and kakkalidone did not reduce alcohol toxicity. However, orally administered kakkalide and intraperitoneally administered irisolidone significantly reduced the mortality. Orally administered kakkalide and intraperitoneally injected irisolidone greatly reduced serum alanine aminotransferase and aspartate aminotransferase activities in ethanol-intoxified mice. Orally administered kakkalide and intraperitoneally administered irisolidone significantly lowered the level of blood ethanol. The results indicate that kakkalide is a prodrug of irisolidone in protecting against ethanol-induced lethality and hepatic injury.

Abstract
This study was performed to investigate the effect of Puerariae Flos (PF) and Puerariae Radix (PR) water extracts on the activities and mRNA expression of three hepatic antioxidant enzymes in ethanol-treated rats. Male Sprague-Dawley rats were divided into four groups, a control, ethanol-treated, ethanol plus PF-treated, and ethanol plus PR-treated group with seven rats per group. Ethanol (25 % v/v, 5 g/kg body weight) was orally administered once a day for 5 weeks. The PF and PR water extracts were supplemented in a diet based on 1.2 g of raw PF or PR/kg body weight/day. Ethanol administration without the PF or PR supplement significantly lowered the activities of hepatic Cu/Zn SOD and catalase (CAT), whereas it increased the hepatic GSH-Px activity. However, the PF and PR supplementation resulted in a significant increase in the Cu/Zn SOD and/or CAT activities and a significant decrease in the GSH-Px activity in the ethanol-treated rats. The mRNA levels of these antioxidant enzymes in the ethanol-treated rats were normalized to the control level by the PF or PR supplement. The hepatic glutathione content, which was significantly lower in the ethanol-treated group than in the control group, was also normalized to the control level by supplementing with either PF or PR. The PF or PR supplement resulted in lowering the hepatic malondialdehyde to the control level in the ethanol-treated rats.

Abstract
When the immune system is stimulated there is a concomitant decrease in drug biotransformation and elimination that may results in unwanted drug response and toxic side effects. We investigated the subacute toxicity of a hydroalcoholic extract of Pterodon pubescens seeds (HEPp) to DBA1/J mice with collagen II-induced arthritis. The oral treatment with HEPp reduced the arthritic index without any concomitant alteration in their hematological examination, histopathological analysis and relative or absolute weight of several organs and in several clinical biochemical parameters when compared with the control group. We concluded that daily administration of anti-arthritic doses of HEPp did not induce any detectable subacute toxic side-effect in mice whose host defense mechanisms is active as we can observe in mice with CIA.
