Background:
Flavonoids from Emblica officinalis effectively reduced serum and tissue lipid levels through their
inhibitory effect on the hepatic β-hydroxy-β-methylglutaryl coenzyme A reductase activity. This study aimed to determine the efficacy and safety of E. officinalis extract in adults with dyslipidemia.
Methods:
We searched the following electronic databases: MEDLINE (PubMed), MEDLINE (Ovid), Google Scholar, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Web of Science, and ClinicalTrials.gov from inception until January 31, 2022. Two reviewers independently screened the abstracts, reviewed full-text papers, and critically appraised the quality of included studies. Meta-analysis was performed using the random-effects model. Our primary outcomes were total cholesterol, LDL-C, serum triglycerides, and HDL-C levels, while secondary outcomes included adverse events.
Results:
A total of four randomized trials (N = 227) were included in the final analysis. There were statistically
significant decreases in total cholesterol levels (SMD = -21.23 mg/dL, 95% CI: -34.22, -8.25; P = 0.001) and LDL-C levels (SMD = -25.12 mg/dL, 95% CI: -40.24, -10.00; P = 0.001) and significant increase in HDL-C levels (SMD = 4.74 mg/dL, 95% CI: 0.40, 9.07; P = 0.03) after 12 weeks of intervention favoring the use of the Emblica extract over placebo. However, there were no statistically significant difference in the serum triglycerides levels following 12 weeks of treatment (SMD = -22.28 mg/dL, 95% CI: -53.33, 8.76; P = 0.16). There was high heterogeneity noted across all outcomes: total cholesterol (P = 0.01, I2 = 72%), LDL-C (P = 0.0004, I2 = 83%), HDL-C (P < 0.00001, I2 = 91%) and serum triglycerides (P < 0.00001, I2 = 93 %). The intervention was well tolerated and adverse events reported in the three of four studies were all mild: dyspepsia (7 events – treatment), mild diarrhea (3 events – placebo), fever (1 event – placebo), headache (1 event – placebo).
Conclusion
Compared to placebo, Emblica officinalis fruit extract resulted in lower total cholesterol and LDL-C levels and increased HDL-C levels but with no effect on serum triglyceride levels based on low certainty of evidence. Trials with a larger sample size that directly compare E. officinalis extract to statins, preferably local data, are needed to support its use in patients with dyslipidemia further.

This study is to establish the fingerprint for Phyllanthus emblica and their tannin parts from different habitats by HPLC for its quality control. The determination was carried out on a Diamonsil C18 (4.6 mm x 250 mm, 5 microm) column, with methanol-0.2% glacial acetic acid as mobile phase with gradient elution at a flow rate of 1 mL x min(-1). The temperature was maintained at 30 degrees C and the detected wavelength is 260 nm, Thirteen chromatographic peaks were extracted as the common peaks of the fingerprint of P. emblica, and eleven as the common peaks of P. emblica tannin parts, and five peaks were identified by comparing with referent samples. The fingerprints of 8 samples were compared and classified by similarity evaluation, cluster analysis and principal component analysis (PCA). The similarity degrees of eight P. emblica were between 0.763 and 0.993, while tannin parts were between 0.903 and 0.991. All the samples of P. emblica and their tannin parts were classified into 3 categories. The method was so highly reproducible, simple and reliable that it could provide basis for quality control and evaluation of P. emblica from different habitats.

In the present study, an attempt to evaluate the antimicrobial and antioxidant activity of fungal endophytes inhabiting Emblica officinalis has been made keeping in view the medicinal importance of the selected host plant in Indian traditional practices. A total of four endophytic fungi belonging to Phylum Ascomycetes were isolated from different parts of the plant which were characterized morphologically and by using rDNA-internal transcribed spacer. The most frequently isolated endophyte was Phomopsis sp. The antioxidant activity by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and reducing power assay, and total phenol were evaluated using ethanolic extract of endophytic fungi. DPPH activities in all the ethanolic extract increased with the increase in concentrations. Endophytes, Phomopsis sp. and Xylaria sp. showed highest antioxidant activity and also had the higher levels of phenolics. Antimicrobial activity of fungal extract were tested against four bacteria namely, Escherichia coli MTCC730, Enteroccocus faecalis MTCC2729, Salmonella enterica ser. paratyphi MTCC735 and Streptococcus pyogenes MTCC1925, and the fungus Candida albicans MTCC183. In general, the fungal extracts inhibited the growth of test organisms except E. coli.

Autophagy is a series of catabolic process mediating the bulk degradation of intracellular proteins and organelles through formation of a double-membrane vesicle, known as an autophagosome, and fusing with lysosome. Autophagy plays an important role of death-survival decisions in neuronal cells, which may influence to several neurodegenerative disorders including Parkinson's disease. Chebulagic acid, the major constituent of Terminalia chebula and Phyllanthus emblica, is a benzopyran tannin compound with various kinds of beneficial effects. This study was performed to investigate the autophagy enhancing effect of chebulagic acid on human neuroblastoma SH-SY5Y cell lines. We determined the effect of chebulagic acid on expression levels of autophagosome marker proteins such as, DOR/TP53INP2, Golgi-associated ATPase Enhancer of 16 kDa (GATE 16) and Light chain 3 II (LC3 II), as well as those of its upstream pathway proteins, AMP-activated protein kinase (AMPK), mammalian target of rapamycin (mTOR) and Beclin-1. All of those proteins were modulated by chebulagic acid treatment in a way of enhancing the autophagy. Additionally in our study, chebulagic acid also showed a protective effect against 1-methyl-4-phenylpyridinium (MPP+) - induced cytotoxicity which mimics the pathological symptom of Parkinson's disease. This effect seems partially mediated by enhanced autophagy which increased the degradation of aggregated or misfolded proteins from cells. This study suggests that chebulagic acid is an attractive candidate as an autophagy-enhancing agent and therefore, it may provide a promising strategy to prevent or cure the diseases caused by accumulation of abnormal proteins including Parkinson's disease.

Stress affects the male reproductive system and can cause sub-fertility or infertility. Although Phyllanthus emblica L. (PE) extract has been shown to have high antioxidant capacity and protective properties in damaged tissue, the preventive effects of PE extract on testicular function from stress-related impairment have never been demonstrated. This study aimed to investigate the effects of PE aqueous leaf extract on testicular impairment and protein marker changes in rats suffering from chronic stress. Adult male rats were divided into four groups: a control group, a chronic stress (CS) group, and two groups with CS that received different doses of PE extract (50 or 100 mg/kg body weight (BW)). In the treatment groups, the animals were given PE extract daily before stress induction for 42 consecutive days. Stress was induced through immobilization (4 h/d) followed by forced cold swimming (15 min/d). Sperm quality and the histology of the testes and caudal epididymis were examined, as were levels of serum corticosterone, testosterone, and malondialdehyde (MDA). The expressions of testicular steroidogenic acute regulatory (StAR) and tyrosine-phosphorylated proteins were investigated using immuno-Western blot analysis, as these proteins are assumed to play important roles in spermatogenesis and androgen synthesis. The results showed that PE (50 mg/kg BW) significantly increased sperm concentration and testosterone levels, while decreasing corticosterone levels, MDA levels, sperm head abnormalities, and acrosome-reacted sperm in CS rats. In addition, PE at both doses was found to diminish testicular histopathology in the CS rats. We also found that 50 mg/kg BW of PE significantly improved StAR protein expression and altered the intensities of some tyrosine-phosphorylated proteins in testis. We conclude that PE leaf extract at 50 mg/kg BW can prevent testicular damage in rats with CS.

OBJECTIVEThe purpose of the present study was to evaluate the nephroprotective and antioxidant properties of Triphala against bromobenzene-induced nephrotoxicity in female Wistar albino rats.
METHODSAnimals were divided into five groups of six rats and treated as follows: Group I was a normal control and received no treatment, Group II received only bromobenzene (10 mmol/kg), Groups III and IV received bromobenzene and Triphala (250 and 500 mg/kg, respectively), Group V received Triphala alone (500 mg/kg), and Group VI received bromobenzene and silymarin (100 mg/kg). Antioxidant status and serum kidney functional markers were analyzed.
RESULTSBromobenzene treatment resulted in significant (P< 0.05) decreases in the activities of antioxidant enzymes such as catalase, superoxide dismutase, glutathione-S-transferase and glutathione peroxidase as well as total reduced glutathione. There was a significant (P< 0.05) increase in lipid peroxidation in kidney tissue homogenates. There were significant (P< 0.05) reductions in the levels of serum total protein and albumin as well as significant (P< 0.05) increases in serum creatinine, urea and uric acid. The oral administration of two different doses (250 and 500 mg/kg) of Triphala in bromobenzene-treated rats normalized the tested parameters. The histopathological examinations of kidney sections of the experimental rats support the biochemical observations.
CONCLUSIONTriphala treatment alleviated the nephrotoxic effects of bromobenzene by increasing the activities of antioxidant enzymes and reducing the levels of lipid peroxidation and kidney functional markers.
