Fatty acid methyl esters (biodiesel), prepared from transesterification of vegetable oils or animal fats, have gained great importance in substituting petroleum based diesel for combating environmental problems and higher diesel prices. Moringa oleifera fatty acids are among the newly investigated potentials for biodiesel production in recent years. In getting rid of soap formation and thus large waste washing water from biodiesel produced from homogenous catalysts, the use of heterogeneous catalysts is currently preferred due to easily separation and purification of the final products. In this study, biodiesel was produced from moringa oleifera oil using sulfated tin oxide enhanced with SiO2 (SO42−/SnO2−SiO2) as super acid solid catalyst. The experimental design was done using design of experiment (DoE), specifically, response surface methodology based on three-variable central composite design (CCD) with alpha (α) = 2. The reaction parameters in the optimization process were reaction temperature (60°C to 180°C), reaction period (1 to 3 hrs) and methanol to oil ratio (1:6 to 1:24 mol/mol). It was observed that the yield up to 84wt% of moringa oleifera methyl esters can be obtained with reaction conditions of 150°C temperature, 150 minutes reaction time and 1:19.5 methanol to oil ratio, while catalyst concentration and agitation speed are kept at 3wt% and 350 rpm respectively.

Withaferin A (WA) was evaluated for its neuro-protective efficacy on ageing induced striatal dopamine (DA) and behavioural changes in aged rats. Wistar albino rats were divided into group I – young (3 months), Group II – aged (24 months), Group III – aged rats supplemented with WA (50 mg/kg b.w once in a day for 30 days) and Group IV – young rats supplemented with WA (50 mg/kg b.w). The HPLC assay revealed significant decline in the levels of DA and homovanillic acid (HVA) in substantia nigra (SN) and striatum (ST) of aged rat. A marked decline in motor activity of aged rat was observed through open field, beam walking and grid walking motor experiments. These results indicate that ageing reduces nigro-striatal activity as well as nigro-striatal DA levels. Interestingly, the administration of WA (50 mg\kg b.w) resulted in a substantial resurge of DA and HVA in SN and ST and a significant reversal of motor impairment in aged rats. This study is the first report that evidently determines the neuro-protective efficacy of WA on dopaminergic system of SN and ST in aged rats.

Cubeba Officinalis is traditionally effective in the treatment of various kidney ailments, and the main adverse effect of tacrolimus is nephrotoxicity. There is no documented evidence about the ameliorative potential of Cubeba Officinalis in tacrolimus induced nephrotoxicity. The main endeavor of the study was to determine the nephroprotective activity of ethanolic extract of Cubeba Officinalis dried fruits against tacrolimus induced nephrotoxicity in Wistar albino rats. The Cubeba Officinalis dried fruits were collected from the local market, and Male albino rats weighing 200-250 g were used for the study. The dose of is lower 200mg/kg, higher dose 400 mg/kg of test drug (EECO) was used, and silymarin is used as the standard at the dose of 20 mg/kg. The animals were divided into five groups, six animals each, which is started prior to oral administration of tacrolimus and continued with the fourteen days tacrolimus treatment. After the whole period of study, the rats were sacrificed, and histopathological studies and biochemical estimations were carried out. The BUN values  were decreased from 33.60±3.84 in nephrotoxic rats to 28.27±2.48 (200mg/kg) and 20.70±0.81 (400mg/kg),creatinine levels from 1.645±0.21 to 0.926±0.19 (200mg/kg) and 0.638±0.07(400 mg/kg),uric acid levels from 1.822±0.249 to 1.092±0.306 (200 mg/kg) and 0.806±0.181 (400 mg/kg) sodium, potassium and chloride levels from 1.607± 0.091, 2.548± 0.293 and 259.8±6.42 to 1.302± 0.169 , 1.023±0.174 and 134.7±9.138 (200mg/kg of EECO) and 0.586±0.092 , 0.831±0.174 and 130.2±2.29 (400mg/kg of EECO). The Ethanolic extract of cubeba officinalis was found to be effective in treating the nephrotoxicity in tacrolimus induced nephrotoxicity.
