Benefits of seeds are often overlooked. This research showed that 95% ethanol extract of pumpkin seeds exhibited greenish colour, while 95% ethanol extract of sunflower seeds extract exhibited yellowish colour. Crude fat analysis (Soxhlet) contained 29.53\u00b10.58% in pumpkin seeds and 27.74\u00b10.31% in sunflower seeds. Crude protein was significantly higher in pumpkin seeds  (36.69\u00b11.26%)  compared  to  sunflower  seeds  (12.03\u00b10.14%).  FTIR  spectroscopy  revealed functional  groups  such as hydroxyl,  nitrile,  nitric  oxide  in  95%  ethanol extract  for  both  seeds compared to 50% ethanol extracts and powdered forms. ICP -OES indicated that potassium was abundant (4408.20\u00b10.00 mg\/100g) and copper least (3.42\u00b10.00 mg\/100g) in pumpkin seeds. Sunflower seeds contained 3665.85\u00b147.46 mg\/100g potassium and 6.78\u00b10.03 mg\/100g copper. Alkaloid content was significantly higher in 95% ethanol extract of sunflower seeds (5.01\u00b10.10 mg\/g) compared to 50% ethanol extract (4.60\u00b10.16 mg\/g). Pumpkin seeds, 95% and 50% ethanol extracts  contained  3.16\u00b10.10  mg\/g  and  3.04\u00b10.10  mg\/g)  of  alkaloids,  respectively.  The  95% ethanol extracts had higher tannin content, with pumpkin seeds containing 0.91\u00b10.008 mg CE\/mL for  pumpkin  seeds  and  sunflower  seeds  (0.81\u00b10.003  mg  CE\/mL),  compared  to  50%  ethanol extracts. This research aligns with sustainability approach and SDG 12 framework.<\/p>\r\n        \r\n                    <p><strong>Keywords:<\/strong>\r\n                colorimetry, Cucurbita moschata, ethanol extraction, FTIR, Helianthus annuus, minerals            <\/p>\r\n            <\/div>\r\n\t\r\n\t\r\n\t\r\n\t<div class=\"asmsj-citation-box\">\r\n        <h3>How to Cite<\/h3>\r\n        <p id=\"citation-text\">\r\n            2026.
