As the prevalence of obesity and hypercholesterolemia are very common in our society, plants with cholesterol lowering action has great value in modern therapeutics. The phytochemicals present in the extracts of Averrhoa bilimbi were analyzed and its effect on lowering cholesterol in various fatty food materials was evaluated in vitro. Various phytochemical compounds like tannins, saponins, alkaloids, emodins, proteins, carbohydrate, terpenoids, glycosides, flavonoids, coumarins and phenols were found in the fruit extracts of the plant. The level of cholesterol was evaluated by Zak’s method in five different fatty food materials. After the treatment with extract four of them showed significant reduction in the cholesterol level day by day and no change in the cholesterol level was observed in one sample.

5. Results and discussion
The phytochemical screening of the extract of Averrhoa bilimbi revealed the presence of compounds like alkaloids, coumarins, carbohydrates, flavonoids, proteins, phenol, phlobatannins, saponins, steroids and terpenoids.
The presence of flavonoids and phenols indicated that Averrhoa bilimbi, has potential antioxidant activity due to the synergistic effect of these phytoconstituents (Thamizh Selvam et al., 2015). The present study has well demonstrated the phytochemical diversity of Averrhoa bilimbi fruit extract. The presence of flavonoids, coumarins, saponins and phenols was well established in the present study which is also at par with available reports from different regions (Kumar et al., 2013). The presence of primary metabolites like carbohydrate and protein and secondary metabolites like flavanoid, alkaloid, phenol and coumarin was reported from Averrhoa bilimbi leaves (Alisha and Raphael, 2016). Similar observations are reported by Yan et al. (2013) too. In short, Averrhoa bilimbi fruit can be recommended as a neutraceutical functional food.

Frequently Asked Questions
What is the primary focus of this research study?
The study focuses on the phytochemical characterization of the Averrhoa bilimbi fruit and its potential to lower cholesterol levels in various high-fat food items.
What are the main thematic fields covered in the work?
The work integrates plant pharmacology, biochemistry, and nutritional science, specifically looking at how natural plant compounds can be used to manage lipid levels.
What is the central research question?
The study seeks to determine if extracts from Averrhoa bilimbi fruit pulp can effectively reduce the cholesterol content in fatty foods under laboratory conditions.
Which scientific method is used to measure cholesterol?
The researchers utilized the standard Zak’s method to estimate and compare cholesterol concentrations in samples before and after treatment with the plant extract.
What does the main body of the work address?
The main body covers the systematic extraction of plant materials, a comprehensive screening for various phytochemicals (such as alkaloids, flavonoids, and phenols), and the experimental analysis of cholesterol reduction over time.
Which keywords best describe the paper?
The paper is best described by keywords such as Averrhoa bilimbi, hypercholesterolemia, lipid-lowering, phytochemical screening, and anti-hyperlipidemic activity.
Did the researchers observe any changes in the cod liver oil samples?
Interestingly, the study noted that while other fatty foods showed a day-by-day reduction in cholesterol, the cholesterol levels in cod liver oil remained unchanged during the experiment.
How long did it take for significant cholesterol reduction to occur?
The results indicated that while initial changes were minimal, a significant reduction in cholesterol levels was observed after one week of incubation with the plant extract.
