ABSTRACT

OBJECTIVE To compare the similarities and differences between raw and different preparations of Terminalia chebula based on fingerprint, antioxidant spectrum-effect correlation and multi-component contents, and to provide a reference for searching for modern processing methods of T. chebula that are similar to classical ancient methods. METHODS Ten batches of raw and different preparations of T. chebula (single stir-fried products, bran-roasted products, sand-scorched products, ash-roasted products, stir-fried charcoal products, and wine-steamed products) were used as test samples. The high-performance liquid chromatography (HPLC) fingerprints of different samples were established by using the Similarity Evaluation System for Chromatographic Fingerprint of TCM (2012 edition), the chromatographic peaks were identified, and chemometrics analysis was carried out. At the same time, HPLC method was used to determine the contents of 8 identified components. The antioxidant capacity of raw and different preparations of T. chebula was determined by DPPH free radical scavenging method, and the spectrum- effect relationship was analyzed. RESULTS A total of 20 common peaks were identified in the fingerprints of the raw and different preparations of T. chebula, and the similarity of each sample was >0.9. Nine common peaks were identified from the raw and different preparations of T. chebula, including chromatographic peak 2 (chebulic acid), 3 (gallic acid), 6 (punicalagin A), 8 (punicalagin B), 12 (corilagin), 15 (chebulagic acid), 18 (ellagic acid), 19 (1,2,3,4,6-O-pentagalloyl glucose), 20 (chebulinic acid), etc. Compared with crude drug, the contents of the above 8 components (punicalagin A and B are recorded as punicalagin) in different preparations of T. chebula were changed, and the changes of the contents of the stir-fried charcoal and wine-steamed products were more obvious than those of other processed products. Chemometric analysis showed that the fingerprints of stir-fried charcoal and wine-steamed products of T. chebula were obviously distinguished from other processed products, and the fingerprint information of raw products and other processed products of T. chebula was partially overlapped. Four main differential components (chebulinic acid, chebulagic acid, gallic acid, ellagic acid) were obtained between raw and processed products of T. chebula; and four main effective components (chebulinic acid, chebulagic acid, gallic acid, corilagin) were obtained by analyzing the spectrum-effect relationship of antioxidant activity. The single stir-fried product of T. chebula showed the strongest antioxidant activity. CONCLUSIONS The single stir-frying method is a modern processing method of T. chebula which is similar to the classical ancient method and is more excellent.

METHODS :Using H 9c2 cardiomyocytes isolated from rat as subjects ,CCK-8 assay was used to detect the effects of 0.5,1,2,4,6,8,10 mg/mL raw A. kusnezoffii and A. kusnezoffii processed with T. chebula on cell inhibition rate after cultured for 4,8,12,24 h. Hoechst 33258 staining was used to observe the effects on cell morphology characteristics after treated with 2,4,6 mg/mL raw A. kusnezoffii and A. kusnezoffii processed with T. chebula . Using macrophages RAW264.7 cells as subjects ,CCK-8 assay was used to detect the effects of 0.05,0.1,0.25,0.5,0.75,1,1.5,2 mg/mL raw A. kusnezoffii and A. kusnezoffii processed with T. chebula on cell survival rate after cultured for 24 h. ELISA assay was used to detect the effects of 0.05,0.1,0.25,0.5 mg/mL raw A. kusnezoffii and A. kusnezoffii processed with T. chebula on the release of NO , TNF-α and IL-6 in RAW 264.7 inflammation cells induced by LPS. RESULTS :When the mass concentration was 0.5,1 mg/mL, neither raw A. kusnezoffii and A. kusnezoffii processed with T. chebula had no inhibitory effect on H 9c2 cells. When the mass concentration was 2 mg/mL,the inhibitory effects of A. kusnezoffii processed with T. chebula on H 9c2 cells was higher than that of raw A. kusnezoffii (P<0.05 or P<0.01);fluorescence intensity of cells treated for 24 h was stronger than that of raw A. kusnezoffii,but its nucleus was intact. When the mass concentration was 4-10 mg/mL,the inhibitory rate of A. kusnezoffii processed with T. chebula on H 9c2 cells at different time points (except for 24 h culture of 8,10 mg/mL)was significantly lower than raw A. kusnezoffii (P<0.05 or P<0.01). The characteristics of cell morphology also showed that the fluorescence intensity of raw A. kusnezoffii group at 4,6 mg/mL was stronger than that of A. kusnezoffii processed with T. chebula group,and the cell nucleus fragmentation was more serious in the raw A. kusnezoffii group. 0.05-0.5 mg/mL raw A. kusnezoffii and A. kusnezoffii processed with T. chebula had no toxicity to RAW264.7 cells. 0.25,0.5 mg/mL raw A. kusnezoffii and 0.1,0.25,0.5 mg/mL A. kusnezoffii processed with T. chebula showed significant inhibitory effect on the release of NO ,0.05,0.1,0.25,0.5 mg/mL raw A. kusnezoffii and A. kusnezoffii processed with T. chebula showed significant inhibitory effect on the release of TNF-α and IL-6 in RAW 264.7 cell(P<0.05 or P< 0.01). The inhibitory effects of A. kusnezoffii processed with T. chebula at the same concentration on the release of NO was better than that of raw A. kusnezoffii ,but poorer than raw A. kusnezoffii in the inhibitory effects on the release of TNF-α and IL-6. CONCLUSIONS:The toxicity of A. kusnezoffii can be reduced after processed with T. chebula ,especially the toxicity of it in medium or high concentration and short-term use is lower than that of raw A. kusnezoffii . At the same time ,the anti-inflammatory effect of A. kusnezoffii processed with T. chebula is comparable to that of raw A. kusnezoffii at the same concentration.

ABSTRACT

Aim:To study the anti-hyperlipidemic activity of Terminalia chebulain rats.Study Design:Hyperlipidemia was induced by administering doxorubicin and the effect of Terminalia chebulawas studied in male and female rats.Methodology:Three doses of hydroalcoholic extract of Terminalia chebula(0.25, 0.5 and 1.0 gm/kg, body weight, per orally for 28 days) was tested against the doxorubicin (0.25 mg/kg, intra-peritoneal, 6 doses for 12 days) in male and female rats. Serum levels of total cholesterol, triglycerides, low-density lipoprotein (LDL-cholesterol) and high-density lipoprotein (HDL-cholesterol) were estimated. The antioxidant effect was determined by estimating the serum peroxidation levels. The result of the data was analyzed statistically by One-way Anova followed by Bonferroni comparison test. p<0.05 was considered to indicate the significance of the results.Results and Discussion: The data indicated that a dose-dependent significant (p<0.05) reversal was observed in the doxorubicin-induced elevated total cholesterol, triglycerides, LDL-cholesterol and diminished HDL-cholesterol upon treatment with Terminalia chebulain male rats. In the female rats, only the highest tested doseof Terminalia chebula(1 gm/kg) produced the inhibitory effect in the elevated lipid levels without affecting significantly the HDL-cholesterol activity. Further, when Terminalia chebulawas tested separately at 0.5 g before and after the administration of doxorubicin, a significant inhibition was observed in the post treatment in both sexes. Serum lipid peroxidation was found to be significantly (p<0.05) reduced by the extract compared to the doxorubicin group. Conclusion:The results suggest that Terminalia chebulaextract might have the potential to reduce doxorubicin-induced hyperlipidemic complications if administered together or after thedoxorubicin therapy

ABSTRACT

OBJECTIVE: To investigate the best compatibility proportion of Mongolian medicine “Terminalia chebula decomposing the poison of Aconitum kusnezoffii”. METHODS: Totally 40 rats were randomly divided into blank control group (0.05% CMC-Na), raw A. kusnezoffii group (0.12 g/kg by crude drug) and raw A. kusnezoffii-T. chebula  (1 ∶ 3,1 ∶ 1,3 ∶ 1, mass ratio) group (0.12 g/kg raw A. kusnezoffii by raw material), 8 rats in each group. They were given relevant medicine intragastrically once a day, for consecutive 28 d. 0.5 h after last medication, serum contents of cTn-I and MB were determined, and the changes of cardiological structure were observed; the detoxification effects of T. chebula on cardiotoxicity induced by A. kusnezoffii were investigated. Binding rates of 3 kinds of aconitine (concentrations of aconitine, mesaconitine and hypaconitine were 5, 10, 20, 40, 80, 160, 400 ng/mL) to binding rate of plasma protein with normal human plasma were determined by equilibrium dialysis combined with liquid chromtography-mass spectrometry. The concentrations of 3 kinds of aconitine were fixed as 100 ng/mL. After adding main detoxification component tannic acid in different proportions of T. chebula (1 ∶ 0.025, 1 ∶ 0.075, 1 ∶ 0.1, 1 ∶ 0.5), the effects of them on plasma protein binding rate of 3 kinds of aconitine were investigated; the possible mechanism  of T. chebula decomposing the poison of A. kusnezoffii inducing cardiotoxicity were investigated. RESULTS: In detoxification experiment, compared with blank control group, serum contents of cTn-I and MB were increased significantly in raw A. kusnezoffii group (P<0.05). There were obvious pathological changes in myocardial tissue, such as disorder of cell arrangement, cell shrinkage and cytoplasm staining. Compared with raw A. kusnezoffii group, serum contents of cTn-I and MB in raw A. kusnezoffii-T. chebula (1 ∶ 3, 1 ∶ 1, 3 ∶ 1) groups were decreased significantly (P<0.05), and there was no significant difference between the raw A. kusnezoffii-T. chebula (3 ∶ 1, 1 ∶ 1) groups and blank control group (P>0.05); myocardial pathological changes were improved to varying degrees. The structure of myocardial tissue in raw A. kusnezoffii-T. chebula (3 ∶ 1) groups were similar to blank control group. In the mechanism investigation experiment under the condition of different concentrations, plasma protein binding rates of 3 kinds of aconitine with normal human plasma were about 30%, without statistical significance (P>0.05) and significant concentration-dependent manner. After adding tannic acid, plasma protein binding rate of 3 kinds of aconitine in A. kusnezoffii was decreased to different extent; when 3 kinds of aconitine were combined with tannic acid in the ratio of 1 ∶ 0.1, 1 ∶ 0.075 and 1 ∶ 0.5, the plasma protein binding rate decreased significantly (P<0.05), in proportion-dependent manner. CONCLUSIONS: Compatible use of raw A. kusnezoffii-T. chebula (3 ∶ 1) show that best detoxification effect on A. kusnezoffii-induced cardiotoxicity. Under this compatibility ratio, the plasma protein binding rate of 3 kinds of aconitine in A. kusnezoffii with normal human plasma is relatively high and the free drug concentration is relatively low.

Harbal plants such as Terminalia chebula (Haritaki) may have free radical scavenging activity thereby can be used for the prevention and treatment of liver damage. Objective: To observe the effect of Terminalia chebula on paracetamol induced changes of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in Wister albino rats. Methods: This experimental study was carried out in the Department of Physiology, Dhaka Medical College, Dhaka from January to December’ 2013. Total 44 rats with age 90 to 120 days, weighing between 150 to 200 gm were selected. After acclimatization for 14 days, they were divided into base line control (BC, n=11), paracetamol treated control (PC, n=11),Terminalia chebula pretreated and paracetamol treated (TCP-PCT n=11) and paracetamol pretreated and Terminalia chebula treated group (PCP-TCT, n=11). All groups received basal diet for 21 consecutive days. In addition to basal diet, rats of BC received propylene glycol (2ml/kg body weight, orally) and PC received single dose of paracetamol suspension (750mg/kg body weight, orally) on 21st day. Rats of TCP-PCT received Terminalia chebula extract (200 mg/kg body weight, orally) for 21 consecutive days and paracetamol suspension (750mg/kg body weight, orally) on 21st day. Again, rats of PCP-TCT received paracetamol suspension (750mg/kg body weight, orally) on the 1st day and Terminalia chebula extract (200 mg/kg body weight orally) for 21 consecutive days. All rats were sacrificed on 22nd day and then blood samples were collected. For assessment of liver function serum AST and ALT levels were estimated by using standard laboratory kits. The statistical analysis was done by one way ANOVA and post hoc Bonferroni test as applicable. Results: The mean serum AST and ALT levels were significantly (p<0.001) higher in PC in comparison to those of BC. Serum AST and ALT levels of all experimental groups were significantly (P<0.001) lower than PC group. Conclusion: From the results of this study, it may be concluded that Terminalia chebula may have some hepatoprotective effects in paracetamol induced liver damage in rats.

ABSTRACT

The present study was aimed to investigate antioxidant, analgesic and cytotoxic activity of the methanolic extract of Terminalia chebula Retz. fruits. Antioxidant potential of the extract was evaluated by using nitric oxide scavenging assay, reducing power and total antioxidant capacity. The extract showed significant activities in all antioxidant assays compared to ascorbic acid in a dose dependent mode. In nitric oxide scavenging assay, the IC50 value of the extract was found to be 51.3 μg/mL while the IC50 value of ascorbic acid was 77.4 μg/mL. In addition to strong reducing power, total antioxidant activity of the extract was also found to increase in a dose dependent manner. The analgesic activity was evaluated using acetic acid-induced writhing test in mice. The extract, at a dose of 500 mg/kg, showed a maximum of 44.17 % inhibition (p < 0.05) of writhing reaction compared to the reference drug diclofenac-sodium (66.96 %). The extract also showed moderate cytotoxic activity in brine shrimp lethality bioassay and the LC50 value was found to be 97.36 μg/mL.

ABSTRACT

The present study aims to evaluate healing effect of 50% ethanolic extract of Terminalia chebula fruit pulp (TCE) on trinitrobenzene sulfonic acid (TNBS, intra-colonic route) induced colitis in rats. TCE (600 mg/kg, oral) was studied in TNBS-induced colitis for its effects on fecal output, food and water intake and body weight changes, histology, antibacterial activity and levels of free radicals (nitric oxide and lipid peroxidation), antioxidants (superoxide dismutase; catalase and reduced glutathione) and acute inflammatory marker (myeloperoxidase) in colonic tissue. TNBS administration increased colonic mucosal damage and inflammation (macroscopic and microscopic) and stool output but decreased body weight which was reversed by TCE treatment. TCE showed significant antibacterial activity and enhanced the antioxidants but decreased free radicals and myeloperoxidase activities affected in TNBS colitis. Thus, Terminalia chebula dried fruit pulp extract healed colitis by promoting antioxidant status and decreasing intestinal bacterial load, free radicals and myeloperoxidase responsible for tissue damage and delayed healing.

ABSTRACT

Medicinal plants are part and parcel of human society to combat diseases from the dawn of civilization. Terminalia chebula Retz. (Fam. Combretaceae), is called the 'King of Medicine' in Tibet and is always listed at the top of the list of 'Ayurvedic Materia Medica' because of its extraordinary power of healing. The whole plant possesses high medicinal value and traditionally used for the treatment of various ailments for human beings. Some of the folklore people used this plant in the treatment of asthma, sore throat, vomiting, hiccough, diarrhea, dysentery, bleeding piles, ulcers, gout, heart and bladder diseases. The plant has been demonstrated to possess multiple pharmacological and medicinal activities, such as antioxidant, antimicrobial, antidiabetic, hepatoprotective, anti-inflammatory, antimutagenic, antiproliferative, radioprotective, cardioprotective, antiarthritic, anticaries, gastrointestinal motility and wound healing activity. But no systematic updated information on the therapeutic effectiveness of Terminalia chebula, a popular herbal remedy in India and South-East Asia has so far been reported. This review highlights an updated information particularly on the phytochemistry and various pharmacological and medicinal properties of Terminalia chebula Retz. and some of its isolated compounds, along with their safety evaluation. This may provide incentive for proper evaluation of the plant as medicinal agent against the human diseases and also to bridge the lacunae in the existing literature and future scope which may offer immense opportunity for researchers engaged in validation of the traditional claims and development of safe and effective botanical medicine.
