Nigella Seeds: A Deep Dive into Their Health Power

A recent study examined various Nigella seed types cultivated in India, focusing on oil production and internal chemical composition.

Key Findings

• Oil Yield:
• Highest: ~30 %

• Lowest: ~10 %

• Fatty Acid Composition (via GC‑MS)
• Predominant: Linoleic acid

• Significant amounts of oleic, palmitic, and stearic acids

• Polyunsaturated Fat Content: 57 %–72 %
• PUFA/SFA ratio: up to 5.45

• MUFA + PUFA / SFA ratio: up to 6.95

• Thymoquinone Levels

• Variable across samples; peak at 247 µg per 100 mg seed in the AN‑13 variety

• Other Antioxidants
• Phenols: ~2.5–11 mg/g oil

• Flavonoids: 0.6–2.8 mg/g

• Thymoquinone Index: 0.3–1.6 mg/g oil

Varieties with Superior Profiles

Using multivariate analysis, nine varieties emerged as standout candidates:

These lines combine high oil output, abundant healthy fats, potent antioxidant power, and rich bioactive compounds.

Implications

The identified varieties are prime candidates for:

• Functional foods and nutraceuticals
• Pharmaceutical applications
• Guiding breeding programs aimed at enhancing the nutritional value of Nigella seeds
