Asteracantha longifolia, Asparagus falcatus, Vetiveria zizanioides, Coriandrum sativum and Epaltes divaricate have proven hepatoprotective and antioxidative effects against carbon tetrachloride and paracetamol induced hepatotoxicity in mice and are widely used in Sri Lanka for the treatment of liver disorders. However, toxicological information regarding their safety after exposure to experimental animals or humans is not available. The present study was designed to evaluate repeated dose toxicity of the five aqueous extracts mentioned above. Healthy, ICR mice were treated with 0.9g/kg (orally) of aqueous extracts daily, for a period of 30 days. Animals were observed for effects on body weight, food consumption, external appearance and mortality. Biochemical, haematological and histopathological parameters were estimated in all groups at the end of 30 days. Aqueous extracts tested didn’t produce mortality, changes in behaviour, difference in body weight, feeding habits or any other physiological activities in mice, at the dose administered. Biochemical or haematological analysis showed no marked differences in any of the parameters examined in either the control group or in the plant...

Enhanced production of anthraquinones from cell suspension cultures of Oldenlandia umbellata were established through elicitor or precursor treatment. Stock cell suspension cultures were developed in liquid MS medium supplemented with 2.5 µM NAA using friable calli. Standardization experiments of suspension cultures revealed that 10 µM NAA added liquid MS medium was optimum for the growth and AQ accumulation from O. umbellata suspension cultures. 10 µM NAA produced 9.96 mg g -1dw AQ on 30th day of incubation. Later enhanced AQ production was achieved by the addition of elicitors or precursors into the standardized media on 25th day of incubation and AQ quantification was done after 5 days of incubation. Addition of elicitors or precursors resulted in a sudden increase in AQ content. 25 mg L-1 pectinadded suspension cultures produced 35.67 mg g-1dw AQ and precursor feeding with 50 mg L-1α-keto glutaric acid resulted in the accumulation of 42.63 mg g-1dw AQ. HPLC analysis of elicitor or precursor mediated suspension cultures revealed the presence of alizarin and purpurin in samples....

The best QSAR model were generated with left of adept and significant descriptors like electronic, lipophilic and topological, using multiple linear regression (MLR) and partial least square (PLS), model further explained by using forward feed neural network analysis (FFNN). QSAR is a kind of technique that directly correlates in between chemical structure to their biological activity. The best MLR statistical expressions were evaluated with good predictive and authenticated ability and the values were S =0.367, F =53.06 r =0.910, r² =0.828, r2(cv)=0.780. The r2 (training and test-set) values of MLR, PLS and FFNN are 0.82, 0.71, 0.82, 0.71 and 0. 81, 0.74 respectively, which predicts the soundness of the model. The model reveals that total dipole moment, bond lipole and kappa 3 are prerequisite descriptors for determining further promising GSK-3β antagonist with high and liable potency against target. In addition to QSAR modelling, Lipinski’s rule of five was employed on a series and we found no violation in it, which means 3-aryl- 4-(arylhydrazono) 1H pyrazol-5-ones has enough good pharmacokinetic...

Caralluma lasiantha is a succulent plant belongs to Ascalpedaceae family. The objective of this study was to evaluate and to compare the anti-hyperglycemic effect of Caralluma lasiantha with Chromium Picolinate on hyperglycemia induced by Cafeteria-Diet in Wistar albino rats. Hyperglycemia was induced in experimental rats by feeding Cafeteria-Diet for a study period of 90 days. Caralluma lasiantha (10, 20, and 40 mg/kg b.w.) & Chromium Picolinate (10 mg/kg b.w.) were administered orally once every day throughout the study and serum glucose levels were determined in different experimental days. Treatment with Caralluma lasiantha significantly reduced the serum glucose level in dose dependant manner. Data reveal an appreciated beneficial effect of Caralluma lasiantha on hyperglycemic rats. Caralluma lasiantha possesses anti-hyperglycemic effect, which promisingly support the use of Caralluma lasiantha as a food supplement or an adjunct treatment for...

The present study explores the nutritional properties of R. mucronata leaves, an edible red mangrove which has been proven as an antidiabetic and as an alternative source of tea leaves and animal feed. Proximate composition, amino acid profiles and physico-chemical properties were analyzed to evaluate the nutritional property. Nutritional evaluation of R.mucronata illustrates it as a rich source of essential aminoacids and unsaturated fatty acid (alpha linoleic and linoleic acid). Total dietary fiber content, protein, ash, carbohydrate and lipid content was found to be 11.9 ± 0.2, 2.445 ± 0.179, 13.5 ± 0.0021, 79.277± 0.079 and 0.749 ± 0.049 % DW respectively. Mineral and vitamin analysis per 100 g (DW) showed the presence of sodium (80.804 ± 4.0 g), calcium (22.32± 1.1g), potassium (7.96 ± 3.9 g), iron (53.6 ± 0.5mg), magnesium (38.15 ± 0.38 mg) and Vitamin A (2.2 ± 0.02 mg), Vitamin C (3.23 ± 2.3g), Vitamin E (1.180± 1.8 g), vitamin B1 and B2 (18.04 ±0.1 and 0.89 ± 0.08 mg). Swelling, water-holding and oil-holding capacity...
