Objective: The aim of the study was to have bio-analytical approach for detoxification process of two poisonous plant materials viz. Aconitum laciniatum (root) and Abrus precatorius (seed) which are used in Ayurvedic preparations. Materials and Methods: For both the species proximate analysis was carried out. For the same plants HPTLC fingerprinting was compared , before and after detoxification process, using triphala quath. Infra red spectral studies for Abrus precatorius species (red and white) were compared, with respect to detoxification process. Protein fingerprinting was carried out for various Aconitum species available in the market. In support of the results obtained from the above methods for detoxification, safety evaluation , post single dose administration, C1- post single dose administration]was done using albino mice as the study model for Aconitum laciniatum (root) and Abrus precatorius (seeds- red and white). Outcome Measures: Comparison of the results for the crude poisonous herbal material with the material obtained after detoxification in triphala quath. Results: HPTLC fingerprinting, Infra red spectral studies, safety evaluation study (animal toxicity)...

Rutin belongs to a class of plant secondary metabolites called flavonoids. Rutin is believed to be a vital nourishing supplement as it is able to make the capillaries stronger. But when administered orally it shows poor absorption because of less lipophilicity. To overcome this limitation, the present study was aimed to develop Rutin- phospholipid complex in different ratio to improve the lipophilic properties of rutin. The prepared complex was evaluated for physicochemical properties and in-vitro DPPH radical’s scavenging activity. The physicochemical properties of the complex were analyzed by ultraviolet-visible spectroscopy (UV), infrared spectroscopy (IR) and X-ray diffractometry (XRD). The results showed that rutin-phospholipid in the complex were joined and did not form a new compound. Results of DPPH radical are scavenging activity revealed that among all ratios of complex, 1:3 next to this 1:2 followed by 1:1. The study was concluded that the free radical scavenging activity was observed in concentration dependent...

In the present investigation, 4-chloro acetophenone on condensation with 2-nitro benzaldehydes in methanolic NaOH solution yielded the corresponding chalcone. These chalcone were further reacted with Isonicotyl hydrazide and semicarbazide in ethanol which led to the formation of chalcone Isonicotyl hydrazone and chalcone semicarbazone derivatives respectively. The newly synthesized derivatives and there copper complexes were characterized on the basis of their chemical properties and spectroscopic data such as IR, NMR and UV. All newly synthesized compounds were evaluated for their antibacterial activities against E. coli and S. aureus also for antifungal activities against P....

The study was designed with an aim to evaluate the antiperoxidative potential of ascorbic acid on busulfan-induced lipid peroxidation. The study was performed in vitro using goat liver as lipid source. This evaluation was done by measuring the 4-hydroxy-2-nonenal (4-HNE) and nitric oxide (NO) content of liver tissue homogenates as markers of lipid peroxidation. The study reveals the lipid peroxidation induction capacity of busulfan and the antiperoxidative potential of ascorbic acid on busulfan-induced lipid...

The main objective of study was to formulate SEDDS of Spironolactone in order to achieve a better dissolution rate which would further help in enhancing oral bioavailability. SEDDS are isotropic mixtures of oils and surfactants, sometimes containing cosolvents. The present research work describes a Self Emulsifying Drug Delivery System (SEDDS) of Spironolactone using oils (Arachise oil, Oleic Acid, Castor oil, Soyabean Oil, Neobee M5, Migloyol, Capmul), surfactants (Tween-80, Cremophor RH40,Cremophor EL) and adsorbents (Aerosil-200,Avicel PH101,Lactose, Dextrose, Mannitol and Talc). In case of SEEDS of Spironolactone, the release rates of all oils were very rapid in Avicel PH101(above 82%) because it has the best flow property among the other absorbents. It Self Emulsifying Drug Delivery System observed that the release pattern from Arachis oil (92.95%), Oleic acid (90.21%) and Castor oil (97.54%) were better in comparison to other oils. Besides, it can be comprehend that the release rate of the three oils were very rapid in Tween-80(above 85%) because it has the best emulsifying property than Cremophor RH40 and Cremophor...
