Chlorella pyrenoidosa is a fresh water microalgae used as substrate for production of value added products like biodiesel. In this investigation C.pyrenoidosa was grown for ten days in an internally illuminated bubble column photobioreactor at: 450 lux green light (495–570 nm), 480 lux red light (620–750 nm), 1663 lux blue light (450–495 nm), 1986 luxwhite light (380 to 750 nm).The results after a period of ten days of growth, showed that C.pyrenoidosa has grown better under blue light when compared to the other types of light. C.pyrenoidosa biomass produced 33.8% of lipid contentwhen grown under blue light, indicating its potential as alternative source of...

To investigate the effects of ginger-juice (Zingiber officinale roscoe) on amphetamine-induced locomotor activity in rat. Methods: (A) Albino rats (n=6-12) were administered G.J at the single doses (4 ml/rat, p.o) as single administration (acute) and chronic treatment over period of 7 days. Following this assessment was done. Effect of treatment with G.J acutely and chronically (7days) administered, was assessed. Parameters used during assessment were locomotor activity. Results: The ginger-juice treatment of acute and chronic (4ml/rat for 7 days) and amphetamine-induced locomotor activity has not produced any effect on any parameter of the loco motor activity Conclusion: Ginger administered itself did not affect loco motor activity as well as amphetamine-induced enhancement of loco motor...

A simple and sensitive spectrophotometric method was developed and optimized for the determination of content of mono isopropylamine at very low levels in Carisoprodol and Isoproterenol hydrochloride. The method was based upon the observation, that characterstic colour results up on addition of colour reagent (consists of Acetyl acetone, formaldehyde and pyridine) and heat for 10 minutes on water bath to form coloured complex. This coloured complex is slightly yellow and its absorption maximum at 420 nm. The optimized method was validated to prove its performance characterstic by demonstrating selectivity, sensitivity(limit of detection and quantification), linearity, precision and accuracy. The established limit of detection and limit of quantification of mono isopropylamine was found to be 3.3µg/ml and 10µg/ml respectively. The present work was aimed to develop a visible spectrophotometric method, which is simple, sensitive, accurate and cost effective to evaluate the quality of the bulk...

Zingiber cernuum belongs to family Zingiberaceae is a perennial herb, also called as Curved stem ginger. The rhizomes of Zingiber cernuum is steam distilled and the composition of essential oil was studied. The essential oil obtained was yellow in colour and the yield was about 0.007%. The chemical profile of the oil was obtained from their GC-MS analysis. The major components present in the oil are trans-Caryophyllene, α-Humulene and δ-3-Carene. The antimicrobial activity of the essential oil was studied using disc diffusion method. The essential oil was tested against four pathogenic stains of gram positive and gram negative bacteria. The essential oil of Zingiber cernuum show considerable antibacterial activity. The oil was found to be active against both gram positive and gram negative bacteria. The anti bacterial activity is mainly due to the major components present in the oil or due to the synergistic effect of the major and minor...

Objective: to investigate the anti diabetic effect of ethanolic extract of Cinnamomum zeylanicum on Alloxan induced diabetes in experimental animals (Rats). Materials and Methods: the alcohol extract of Cinnamomum zeylanicum was tested for its efficacy in Alloxan (150mg/kg) induced diabetic rats. The diabetic rats were divided into 5groups. Group I (control) received 2% gumacasia, groupie (positive control) received standard drug Glibenclamide (10mg/kg+2%GA), group III, IV, V (T1 T2 T3) were treated orally with a daily dose of 50mg/kg, 100mg, 200mg, respectively for 30 days, for all diabetic rats after giving Test, NC, PC preparations, the blood samples were collected and determined the blood glucose level 0,1,3,24hrs intervals. 0hr reading is before drug giving and remaining 3 readings after drugs giving. 24th her reading is considered as 0hr reading for the next day. Results: administration of alcohol of an extract of Cinnamomum zeylanicum produced a dose dependent decrease in blood glucose levels in Alloxan induced rats. There was significant fall in blood sugar level in High dose (200mg/kg) in comparison...
