Essay on Curry Leaves
1. Essay on Curry Leaves (As an Anti-Ageing):
Dementia is a syndrome of gradual onset and continuous decline of higher cognitive functioning. It is a common disorder in older persons and has become more prevalent today. Significant improvement in memory scores of young and aged mice fed curry leaves (20 and 30 mg/kg, p.o.) was demonstrated by Marti et al. (2012).
The alkaloidal extract of curry leaves improved the level of protective antioxidants such as glutathione peroxidase, reduced glutathione, glutathione reductase, superoxide dismutase and catalase in brain homogenate at higher doses (20 and 40mg/kg, p.o.).
Moreover, a dose dependent decline was noted in lipid peroxidation and the nitric oxide assay at all doses (10, 20 and 40mg/kg, p.o.). Interestingly, significant progress was noted with the supplementation of curry leaves by an improvement of the acetylcholine levels and a reduction in the acetyl cholinesterase activity in aged mouse brain.
In addition, a significant elevation of serum albumin, alkaline phosphatase, alanine transaminase, aspartate transaminase and total protein as well as a decline in creatinine, total cholesterol, urea nitrogen and glucose levels with curry leaves also ameliorated the hepatic and renal functions in normal ageing process. Thus Mani et al. (2012; 2013) showed the possible utility of Murraya koenigii leaves in neuro-protection against neurodegenerative disorders such as Alzheimer’s disease.

Dementia is a syndrome of gradual onset and continuous decline of higher cognitive functioning. It is a common disorder in older persons and has become more prevalent today. Significant improvement in memory scores of young and aged mice fed curry leaves (20 and 30 mg/kg, p.o.) was demonstrated by Vasudevan and Parle (2009) and Mani et al. (2012).
The alkaloidal extract of curry leaves improved the level of protective antioxidants such as glutathione peroxidase, reduced glutathione, glutathione reductase, superoxide dismutase and catalase in brain homogenate at higher doses (20 and 40mg/kg, p.o.).

3. Essay on Curry Leaves (As an Anti-Diabetic Foods):
Curry leaves significantly altered the hepatic glycogen metabolism through enzyme modulation i.e. decreased hepatic gluconeogenesis and glycogenolysis by decreasing the activity of glycogen phosphorylase and gluconeogenic enzymes, and increased glycogenesis due to increased activity of glycogen synthetase. Similar results were also observed later by Yadav et al (2002) with different doses of curry leaves (5 per cent, 10 per cent and 15 per cent) fed to normal rats for 7 days as well as mild diabetic and moderate diabetic rats for 5 weeks. Results showed significant hypoglycemic and anti-hyperglycemic effects in diabetic rats.
Aqueous extract of curry leaves lowered blood glucose level in normal as well as in diabetic rabbits. Aqueous as well as methanol extracts of the leaves showed significant reduction (P < 0.05) in blood glucose levels of diabetic rats as compared to diabetic control rats. Plasma insulin was also significantly high on 43rd and 58th days of treatment suggesting that the hypoglycemic effect may be mediated through stimulating insulin synthesis and/or secretion from the beta cells of pancreatic islets of Langerhans.
Similarly, Arulselvan and Subramanian (2007) demonstrated the anti-oxidant and pancreatic β-cell protective effect of M. koenigii. The extract of M. koenigii reverted the increased levels of glucose, glycosylated hemoglobin, insulin, thiobarbituric acid reactive substances (TBARS) to normalcy while improving the enzymatic and non- enzymatic anti-oxidant concentrations.
In addition, curry leaf administration showed nephron protective activity in diabetic rats as the aqueous extract of leaves produced a significant dose-dependent decrease in serum urea and creatinine levels, and a marked increase in the levels of plasma anti-oxidant capacity.
Histological studies of the kidneys of these animals showed comparable tissue regeneration by the aqueous extract thus, scientifically supporting the traditional belief of using the leaves of Murraya koenigii as adjuvant, in the treatment of pain disorders related to renal impairments among diabetics.
Curry leaves also exhibited anti-inflammatory effect in diabetic mice. A reduction in interleukin-2, 4 and 10, tumor necrosis factor-α expression and the reduction of apoptosis in pancreatic cells revealed the anti-inflammatory response.
The hypoglycemic effect of curry leaves was not found to be affected by processing. Freeze dried curry leaves lowered blood glucose level and improved glucose tolerance in normal and diabetic rats on oral administration.
4. Essay on Curry Leaves (As an Anti-Obesity Foods)
Ethanolic as well as methanolic extracts of curry leaves were found to exhibit anti-lipase activity more than 80 per cent. An oral dose of 300 mg/kg/day for 2 weeks of M. koenigii leaves extract for 2 weeks significantly reduced the body weight gain, plasma total cholesterol and triglyceride levels of obese rats.
The anti-obesity and anti-hyperlipidemia activities correlated well with the carbazole alkaloids present in them. Mahanimbine, a carbazole alkaloid, [3, 5-dimethyl-3-(4-methylpent-3-enyl)-11H-pyrano [5,6-a] carbazole], isolated from the petroleum ether extract of the leaves of M. koenigii. (30 mg/kg/day) also significantly lowered the body weight gain as well as plasma total cholesterol and triglyceride levels.
