Phyllanthus emblica Linn is not only an edible fruit with high nutritional value, but also a medicinal plant with multiple bioactivities. It is widely used in clinical practice with functions of clearing heat, cooling blood, digesting food, strengthening stomach, promoting fluid production, and relieving cough. This review summarized a wide variety of phytonutrients, including nutritional components (mineral elements, amino acids, vitamins, polysaccharides, unsaturated free fatty acids) and functional components (phenolic acids (1-34), tannins (35-98), flavonoids (99-141), sterols (142-159), triterpenoids (160-175), lignans (176-183), alkaloids (184-197), alkanes (198-212), aromatic micromolecules (213-222), other compounds (223-239)). The isolated compounds and the various extracts of P. emblica Linn presented a diverse spectrum of biological activities such as anti-oxidant, anti-cancer, anti-inflammatory, anti-bacterial, hepatoprotective, hypoglycemic, anti-atherosclerosis, neuroprotective, enhancing immunity, anti-fatigue, anti-myocardial fibrosis. The quality markers of P. emblica Linn were predicted and analyzed based on traditional medicinal properties, traditional efficacy, plant genealogy and chemical component characteristics, biogenic pathway of chemical components, measurability of chemical components, transformation characteristics of polyphenolic components, homologous characteristics of medicine and food, compound compatibility environment, and clinical applications. This review also summarized and prospected applications of P. emblica Linn in beverages, preserved fruits, fermented foods, etc. However, the contents of mechanism, structure-activity relationship, quality control, toxicity, extraction, processing of P. emblica Linn are not clear, and are worth further studies in the future.

Debittering of Emblica (Phyllanthus emblica L.) fruit powder: Preparation and biological activity

Emblica, also known as Phyllanthus emblica L., is a drug homologous food that is rich in polyphenols with various biological activities. However, its bitterness and astringency pose a significant challenge to its utilization in food products. In this study, we aimed to identify the optimal conditions for debittering Emblica. Our findings revealed that the best debittering conditions were: temperature = 50 °C, pH = 4, α-l-rhamnosidase concentration 200 U/g, and time = 5 h. High-performance liquid chromatography (HPLC) and molecular docking analysis revealed that enzymatic hydrolysis partially removed bitterness compounds. The results of antioxidant activity, xanthine oxidase, and α-glucosidase inhibitory activity assays confirmed that the Emblica fruit powder still exhibited good biological activity after enzymatic debitterization. Moreover, gastric fluids treatment might contribute to the above enhancing effect of enzymatic hydrolysates of Emblica. This study provided a theoretical basis for promoting the processing and utilization of Emblica fruit powder, as well as understanding its biological activity.

Exploring the Mechanism through which Phyllanthus emblica L. Extract Exerts Protective Effects against Acute Gouty Arthritis: A Network Pharmacology Study and Experimental Validation

Increased uric acid levels and inflammatory reactions are the main factors considered responsible for the development of gouty arthritis. Phyllanthus emblica L. (PEL) has several promising pharmacological properties, including anti-inflammation and antioxidation. However, only a few studies have investigated its use for treating acute gouty arthritis (AGA), and the mechanism of action of PEL has not yet been clarified. The aim of this study was to verify the protective effects of PEL against gout and explore its underlying mechanism through network pharmacology and animal experiments. The main active components of the extract from PEL including mucic acid, mucic acid lactone, gallic acid, ethyl hexyl phthalate, and glucose were identified by UPLC-ESI-qTOF-MS. Network pharmacological analysis results revealed 13 active compounds in PEL and 85 related targets for the treatment of gout. The core mechanism of action of PEL is mainly associated with inflammation-related pathways, including the HIF-1, PI3K-Akt, TNF, and NOD-like receptor signaling pathways. Previous studies revealed that the NOD-like receptor signaling pathway, especially the NLRP3 inflammasome, plays an important role in the pathogenesis of AGA; therefore, we mainly investigated the effect of PEL on the NLRP3/ASC/caspase-1 pathway in gout rats. In the animal experiments, PEL was shown to have a satisfactory antigout effect, as it effectively reduced uric acid (UA) and xanthine oxidase (XOD) levels. In terms of inhibiting AGA-associated inflammatory reactions, our results showed that PEL significantly decreased the expression of NLRP3 and caspase-1 in ankle synoviocytes as well as the levels of downstream inflammatory factors, such as TNF-α, IL-10, and IL-1β in serum. Moreover, the results of our study show that PEL reduced MMP13 expression in the ankle synovium. Overall, the results of this study indicate that PEL exerted a therapeutic effect against AGA. Reducing uric acid levels, inhibiting inflammation, and decreasing the expression of MMP13 may be responsible for the therapeutic effect of PEL, which suggests that PEL can be further developed as a drug for the treatment of gout.

Coniferaldehyde ameliorates the lipid and glucose metabolism in palmitic acid-induced HepG2 cells via the LKB1/AMPK signaling pathway

Impaired lipid and glucose metabolism in the liver is a crucial characteristic of nonalcoholic fatty liver disease (NAFLD). Coniferaldehyde (CA), a kind of phenolic compound found in many edible plants, has multiple biological and pharmacological functions. However, since the effect and molecular mechanism of CA on hepatic lipid and glucose metabolism disorders in NAFLD remain unknown, this study investigated its impact on the lipid and glucose metabolism of palmitic acid (PA)-induced HepG2 cells. Compared with the HepG2 cells treated only with PA, supplementation with 25, 50, and 100 µM CA reduced the levels of intracellular triglyceride (by 7.11%, 19.62%, and 31.57%) and total cholesterol (by 8.46%, 23.32%, and 27.17%), and enhanced glucose uptake (by 40.91%, 57.49%, and 61.32%) and intracellular glycogen content (by 12.75%, 41.27%, and 53.77%). Moreover, CA supplementation downregulated the expression of sterol regulatory element-binding protein-1, fatty acid synthase, and stearoyl-CoA desaturase 1 related to lipogenesis while upregulating the expression of carnitine palmitoyltransferase 1α related to fatty acid oxidation. CA supplementation also upregulated the glucose transporter 2 protein expression and phosphorylation of glycogen synthase kinase 3β while downregulating the phosphorylation of glycogen synthase. Most importantly, most of these effects of CA were reversed by pretreatment with AMP-activated protein kinase (AMPK) inhibitor and small interfering RNA-liver kinase B1 (LKB1). In conclusion, CA ameliorated the lipid and glucose metabolism in PA-induced HepG2 cells via the LKB1/AMPK signaling pathway. PRACTICAL APPLICATION: In this study, coniferaldehyde appeared to be effective in ameliorating hepatic lipid and glucose metabolism disorders in nonalcoholic fatty liver disease by reducing the levels of intracellular triglyceride and total cholesterol and enhancing glucose uptake and intracellular glycogen content via the LKB1/AMPK signaling pathway in vitro. Therefore, our findings provide new evidence in support of that supplementation with coniferaldehyde or food rich in coniferaldehyde might be considered as a viable dietary intervention strategy for preventing and treating nonalcoholic fatty liver disease.

The effect of coniferaldehyde on neurite outgrowth in neuroblastoma Neuro2a cells

Neurite outgrowth is the differentiation process by which neurons establish synapses. In the dentate gyrus of the hippocampus, new neurons are constantly produced and undergo neurite outgrowth to form synapses, and this process is involved in cognitive ability. Therefore, if an agent could modulate neurite outgrowth, it could potentially be developed as a compound for modulating cognitive ability. In this study, we examined whether coniferaldehyde, a natural compound, regulates neurite outgrowth in Neuro2a cells. We ascertained morphological changes and measured the percentage of neurite-bearing cells and neurite lengths. Coniferaldehyde significantly increased the percentage of neurite-bearing cells, and the length of neurites in a concentration-dependent manner, without inducing cell death. We then have identified that, coniferaldehyde activates the extracellular signals-regulated Kinase 1 and 2 (ERK1/2), and further noted that, U0126, an ERK1/2 inhibitor, blocks coniferaldehyde-facilitated neurite outgrowth. Moreover, Subchronic administration of CA enhanced learning and memory, and increased neurite length of newborn neurons in the hippocampus. These results suggest that coniferaldehyde induces neurite outgrowth by a process possibly mediated by ERK1/2 signaling and enhances learning and memory.

Neuroprotective and Anti-Amyloid β Effect and Main Chemical Profiles of White Tea: Comparison Against Green, Oolong and Black Tea

White tea (WT) is one of six tea types originally derived from Fujian Province, China. White tea is known for its health-promoting properties. However, the neuroprotective and anti-aggregatory properties of WT against the hallmark toxic Alzheimer's protein, Aβ have not been investigated. In this study, WT, green tea (GT), oolong tea (OT) and black tea (BT) were manufactured using tea leaves from the cultivar Camellia sinensis (Jin Guanyin). The protective effects of these tea extracts were then studied under oxidative stress conditions via t-bhp and H₂O₂ exposure, in addition to Aβ treatment using a PC-12 cell model. Each tea type failed to rescue PC-12 cells from either t-bhp or H₂O₂-mediated toxicity, however each extract exerted significant protection against Aβ-evoked neurotoxicity. Results of the Thioflavin T Kinetic (ThT) and TEM assay showed that Aβ aggregate formation was inhibited by each tea type. Additionally, TEM also supported the different anti-aggregatory effect of WT by modifying Aβ into an amorphous and punctate aggregate morphology. Higher accumulated precedent or potential neuroprotective compounds in WT, including ECG''3Me, 8-C-ascorbyl-EGCG, GABA and Gln, in addition to flavonol or flavone glycosides detected by using UPLC-QTOF-MS and UPLC-QqQ-MS, may contribute to a favourable anti-aggregative and neuroprotective effect of WT against Aβ.

Protective effects of ethyl gallate on H2O2-induced mitochondrial dysfunction in PC12 cells

Oxidative stress has been suggested to play an important role in neuronal injury. Ethyl gallate (EG) is the ethyl ester of gallic acid which has been acknowledged as an antioxidant. We previously demonstrated that EG effectively inhibited H₂O₂-induced cytotoxicity and decreased the ROS levels in PC12 cells, while the relevant mechanisms of action of this compound remain largely uncharacterized. The present study was carried out in an attempt to clarify the underlying mechanisms of EG against H₂O₂-induced neurotoxicity in PC12 cells. EG pretreatment attenuated H₂O₂-induced mitochondrial dysfunction as indicated by the decreased caspase-9/-3 activation, PARP cleavage, mitochondrial membrane potential (MMP) depletion, Bax/Bcl-2 ratio, cytochrome c release and ROS overproduction. Furthermore, EG treatment resulted in nuclear translocation of Nrf2 along with increased expression of ARE-dependent cytoprotective genes, such as γ-GCS and NQO1, which indicated EG as an Nrf2 pathway activator. Silencing of Nrf2 signaling by siRNA abrogated the protective effects offered by EG on H₂O₂-induced PC12 cells injury, which suggested the important role of Nrf2 pathway in the protection of EG against oxidative stress induced PC12 cell apoptosis. These results taken together indicated that EG protects PC12 cells against H₂O₂-induced cell mitochondrial dysfunction possibly through activation of Nrf2 pathway. EG might be a potential candidate for further preclinical study aimed at the prevention and treatment of neurodegenerative diseases.

Two new triterpenoids from the roots of Phyllanthus emblica

Two new triterpenes, the seco-friedelane type secofriedelanophyllemblicine and the ursane-derived saponin ursophyllemblicoside were isolated from the roots of the edible fruit-producing Phyllanthus emblica. Their structures were unambiguously elucidated using extensive 1D and 2D NMR analyses, high resolution mass spectrometry and single-crystal X-ray crystallographic analyses along with comparison with literature data. Secofriedelanophyllemblicine represents the first 3,4-secofriedelane bearing a carboxylic acid group substituent at C-20. Ursophyllemblicoside, incorporating the rare 21α hydroxyursolic acid as a sapogenol represents the first example of saponin comprising this aglycone. Secofriedelanophyllemblicine displayed a moderate cytotoxicity against K562 and HepG2 cancer cell lines.

Understanding cancer and its treatment in Thai traditional medicine: An ethnopharmacological-anthropological investigation

ETHNOPHARMACOLOGICAL RELEVANCE

Thai traditional medicine (TTM) is widely practiced in Thailand and continues to gain importance in cancer management, but little is known about the TTM practitioners' emic concepts and practice.

AIM OF THE STUDY

With this study we firstly aim to document the practice of cancer treatment and prevention by TTM practitioners and, secondly, to evaluate how such traditional concepts and practices are correlated with biomedical ones. This in turn can form the basis for developing novel strategies for designing pharmacological experiments and longer term strategies to develop TTM practice.

METHODS

Semi-structured interviews with 33 TTM practitioners were performed in five provinces in different regions of Thailand. The following information were recorded; basic information of informants, descriptions of cancer (mareng in Thai), causes, diagnosis, treatment, and prevention. Plants used in the treatment and prevention of mareng were also collected.

RESULTS

Using an in depth ethnographic approach four representative case studies to assist in a better understanding of the characteristics of mareng, its diagnosis, treatment, and prevention are reported here. Five characteristics of mareng - waste accumulation (khong sia), chronic illnesses (krasai), inflammation (kan aksep), bad blood (luead) and lymph (namlueang), and the imbalance of four basic elements (dhātu si) - have been identified. Explanatory models of cancer in TTM were linked with biomedical concepts and relevant pharmacological actions. Traditional uses and available scientific evidence of medicinal plants mentioned in the case studies for the treatment or prevention of mareng are presented and discussed.

CONCLUSION

Here for the first time five main characteristics of cancer based on Thai traditional medical concepts are analysed. Our findings are relevant not only for the planning of clinical studies or pharmacological experiment in the search for novel compounds for cancer treatment and prevention, but also for the integration of Thai traditional medicine in cancer care.
