Pumpkin (Cucurbita maxima) is a vegetable crop which is commonly consumed as<br />

vegetables or incorporated into food products. Pumpkin flesh is rich in carotenoid<br />

compounds, which includes α-carotene, β-carotene, β-cryptoxanthin, lutein and<br />

zeaxanthin. There is a possibility that these nutrients to be in other parts of pumpkin such<br />

as peel and seed. Therefore, the objective of this study is to determine the total lutein<br />

content in different parts of pumpkin. The antioxidant properties and antimicrobial<br />

properties of total lutein content in different parts of pumpkin will be also studied.<br />

Consequently, the outcome of this study may utilize the pumpkin waste as natural<br />

antioxidants and antimicrobial agents. For instance, the presence of the antioxidant<br />

properties of total lutein in different parts of pumpkin will be tested through DPPH assay,<br />

FRAP assay and ABTS assay whereas the antimicrobial properties of total lutein in<br />

different parts of pumpkin will be tested by well diffusion method.<br />
