Nigella Seeds: A Deep Dive into Their Health Power

A study looked closely at different types of Nigella seeds grown in India, checking how much oil they produce and what chemicals live inside them. Researchers measured oil yield, found that some varieties give almost 30 % oil while others only give about 10 %. They used a technique called GC‑MS to identify the fats in each seed. Linoleic acid was the main fatty acid, but oleic, palmitic and stearic acids were also present in meaningful amounts. The seeds contained a high share of polyunsaturated fats—between 57 % and 72 %. This gives good health numbers, such as a PUFA to SFA ratio that can reach 5. 45 and an overall MUFA+PUFA to SFA ratio up to 6. 95. The active compound thymoquinone varied a lot among the samples, reaching 247 µg per 100 mg of seed in one type called AN‑13.Other antioxidants, like phenols and flavonoids, were also measured. Their levels ranged from roughly 2½ to 11 mg per gram of oil for phenols and 0. 6–2. 8 mg/g for flavonoids. An index that shows how much thymoquinone is present compared to other oils was between 0. 3 and 1. 6 mg per gram of oil. When the team looked at how sugars, antioxidants and other bioactive chemicals were distributed, they found clear differences between the seed types. Using multivariate statistics, nine varieties stood out: NSC‑6, NSC‑5, AN‑8, AN‑11, AN‑12, AN‑2, NSC‑1, NSC‑2, AN‑35 and AN‑13. These lines combined high oil output, a lot of healthy fats, strong antioxidant power and lots of useful compounds. Because of these traits, the highlighted varieties are valuable for making health‑boosting foods and medicines. They can also guide breeding programs that aim to improve the nutritional benefits of Nigella seeds.
