Outline
• Bitter gourd- a vegetable and medicinal plant
• Primary and secondary antidiabetic effects
• Antidiabetic compounds
• Phytochemical diversity and variation: – In selected germplasm accessions
– In selected commercial varieties
– As affected by ripening stage
– As affected by storage length
– As affected by planting season
Bitter gourd • A vegetable
– Popular in India, China, the Philippines, Taiwan, and Japan
– Consumed worldwide, particularly in Chinese and India communities
• A medicinal plant
– Anti-hyperglycemia
– Anti-hyperlipidemia
– Anti-oxidation
– Anti-inflammation
– Anti-microbial pathogens

Primary effect of anti-diabetics
• Plasma glucose homeostasis
– Decrease carbohydrate digestion & absorption
– Increase insulin secretion
– Increase hepatic glucose utilization
– Increase insulin sensitivity in liver & muscle cells
5
Secondary effects of anti-diabetics
• Reduce inflammation
• Anti-oxidation and reduce/delay oxidative stress
• Increase fatty acid utilization
• Lower blood lipids
• Reduce pre-fat cell proliferation
• Broad-spectrum anti-microbial activity

Bitter Gourd Project
• Goal
– Improved income and quality of life of diabetics in developing countries
• Objectives
– Optimize production of anti-diabetic compounds in bitter gourd through varietal selection, postharvest practices, and preparation methods
– Develop evidence-based dietary strategies using bitter gourd to reduce hyperglycemia (high blood sugar) in type 2 diabetic populations in Asia and Africa

Fig. Base peak chromatogram of of M. charantia (NO 76, spring)
The 30 most affected metabolites were identified: -Amino acids -Alkaloids -Fatty acids -Lysophosphatidylcholines -Lysophosphatidylethanols -Triterpenoids
Conclusions
• Varietal differences were found for all three compound groups (fatty acids, triterpenoids, alkaloids).
• Among germplasm, variation within fatty acids, triterpenoids, and alkaloid were 4-fold, 10-70-fold, 3-fold, respectively.
• Magnitudes of variation within fatty acids, triterpenoids, and alkaloid were similar for commercial varieties.
• Opportunities exist to improve all three compound groups, especially triterpenoids.
Conclusions
• Longer storage led to decreased fatty acids and vitamin C contents, and increased carotenoids and antioxidant activities, but not triterpenoids and alkaloids
• Metabolite types and amounts in bitter gourd fruits were affected by seasons. The 30 most affected metabolites were identified and belonged to the groups of amino acids, alkaloids, fatty acids, lysophosphatidylcholines, lysophosphatidylethanols, and triterpenoids
