Phytochemical Components

Most of biochemical reactions in the body generates Reactive Oxygen Species (ROS), which are involved in the pathogenesis of oxidative stress-related disorders like diabetes, nephrotoxicity, cancer, cardiovascular disorders, inflammation and neurological disorders when they attack biochemical molecules like proteins, lipids and nucleic acid. Antioxidants are used to protect the cells or tissues against potential attack by ROS. Most medicinal plants possess a rich source of antioxidants such as flavonoids, phenols, tannins, alkaloids among others. These phytochemicals are currently pursued as an alternative and complimentary drug. In this study, phytochemical components, antioxidant and acute toxicity study of the methanol extract of stem bark and root of F. sycomorus were carried out using standard methods. Findings from this study revealed the presence of some diagnostic microscopical features such as calcium oxalate, starch, gum/mucilage, lignin, Aleurone grain, suberized/Cuticular cell wall and inulin but calcium carbonate was absent in stem bark but present in the powdered root. Quantitative physical constants include moisture contents (6.40% and 7.82%), ash value (7.20% and 9.30 %) in stem bark and root respectively. Carbohydrates, alkaloid, flavonoids, saponins, tannins, glycoside, steroid, triterpenes and phenols were present in all the extracts. They were found to exhibit potent 1,1,-diphenyl 2-picryl hydrazyl (DPPH) free scavenging activity. The DPPH radical scavenging ability of the extracts showed the following trend Ascorbic acid < stem bark extract˃ root extract. The LD50 of the methanolic stem bark and root extracts were found to be greater than 5000 mg /kg and is considered safe for use. Nonetheless, further

Study Results

Background: Diabetes mellitus is major issue to public health as its prevalence is rising day by day. Synthetic agents available for the diabetic treatment are expensive or produce undesirable side effect on chronic use and some of them are not suitable during pregnancy. Herbal medicines accepted widely due to side effects and low cost. Objective: The aim of present study was to evaluate the activity of Withania coagulans extract using In-vitro and In-vivo model. Methods: Different three types of Withania coagulans extract were prepared using aqueous (W1), Alcohol (W2) and hydro-alcoholic (50:50) mixture (W3). In-vitro Anti-diabetic activity of the all three extracts evaluated using RINm5F Pancreatic beta cells.Further, n-vivo anti-diabetic evaluation performed by administering 50 mg/kg (p.o) aqueous extract for 7 days in Streptozotocin (STZ)-induced mice. Body weight of the animals was also determined to perform acute toxicity study. Results: The results of in –vitro cell based study indicated that among all three extract, aqueous extract (W1) of Withania coagulans showed potential increase in inulin release. The EC50 of the W1 (249.6 µg/L) which is compared with standard (Glibenclamide) EC50. From the results of In-vitro study, W1 subjected for acute toxicity study and the acute toxicity study results indicated LD50 of 50mg/kg. Diabetic rats treated with W1 extract at oral dose of 50 mg/kg for 7 days showed 34.17% reduction in blood glucose in comparison to untreated diabetic (STZ-induced) rats. Blood glucose levels of Standard treated (Glibenclamide) and control untreated. Conclusion: In conclusion, results of pancreatic beta cell based study showed increase in insulin release by administration of extract. Further aqueous extract (W1) was potentially reduced blood glucose level in STZ induced diabetic mice.

Background: The Eucalyptus globulus extractions have been used by the traditional healers to treat diseases in the study area. Our previous study revealed that the essential oil has antimicrobial and antifungal activity. This study determined phytochemical analysis, skin irritation, acute and subacute toxicity of Eucalyptus globulus essential oil in mice and rats. Methods: The phytochemicals were analyzed using GC-MS mass spectrometry. The acute toxicity study was determined at three dose levels of 1500 mg/kg, 1750mg/kg, and 2000 mg/kg. The essential oil limit test at a dose of 1000 mg/kg was administered to mice for 28 consecutive days for sub-acute toxicity study. The mice mortality, behavioral change, injury and other signs of illness were recorded once daily. Biochemical parameters were evaluated. Liver and kidney were analyzed for histopathological analyses. The 5% ointment formulation was applied to the rat skin to determine skin irritation effects. Results: The Eucalyptus globulus essential oil showed no effect on the mice at a dose of 1500mg/kg and below, but caused signs of toxicity and death at a dose of 1750mg/kg and above compared to the controls (p<0.05). The LD50 value was 1650 mg/kg. There was no significant difference (p > 0.05) in the body weights, gross abnormalities of the organs and biochemical parameters compared to the control at 1000 mg/kg subacute toxicity study. No histopathological changes were detected in the organs tested. The 5% ointment formulation did not show any abnormal skin reaction. Discussion: In the present study, the Eucalyptus globulus essential oil was comparable with other studies in terms of both chemical composition and its effects on sub-acute and topical application. Conclusion: This toxicity study demonstrated that Eucalyptus globulus essential oil is nontoxic at a relatively lower concentration.

BACKGROUND: Porang (Amorphophallus oncophyllus) is a local tuber food that high in bioactive compound glucomannan. It uses are limited due to oxalate acid content which poses health risks. Strobilanthes crispus leaves could reduce the level of calcium oxalate in porang. However, there is still no study to prove its safety. AIM: This study aimed to investigate the acute oral toxicity study of porang (A. oncophyllus) macerated with S. crispus based on observation of mortality rate (LD50), the changes in behavior during 72 h, renal and hepatic function such as urinary protein, serum glutamic oxaloacetic transaminase (SGOT), and serum glutamic pyruvic transaminase (SGPT) levels of Wistar rat (Rattus norvegicus) METHODS: An acute toxicity test was conducted based on the Organization of Economic Co-Operation and Development 420 Fixed-Dose Procedure Guideline that consists of preliminary and main studies. For the preliminary study, rats were divided into control and five treatment groups with the dosage of 50, 300, 2000, and 5000 mg/kg body weight (BW) for each natural porang flour (NPF) and S. crispus-macerated porang flour (SPF). For the main study, rats were divided into four groups, those were NPF and SPF with the dosage of 2000 and 5000 mg/kg BW. Levels of urinary protein and blood serum SGOT and SGPT levels were measured at 0, 24, and 72 after treatment. RESULTS: The acute toxicity study showed that porang and porang macerated with S. crispus were not toxic until the highest dose of 5000 mg/kg BW. It was proved by the absence of LD50, no change in behavior, no weight losses, and also the results of biochemical tests, such as urinary protein, SGOT, and SGPT which were still in the normal range. CONCLUSIONS: Porang flour and SPF were concluded as non-toxic food based on acute toxicity study.
