Quantification and Bioaccessibility of β-Sitosterol in Lasuna (Allium sativum Linn) Before and After Processed with Taila and its Bioavailability Using CACO-2 Cell Lines

Summary

This study investigates whether traditional Ayurvedic processing of garlic (Lasuna) with oil (Taila) enhances the bioaccessibility and bioavailability of β-sitosterol, a lipophilic phytosterol of known biological relevance. Using HPLC or similar quantification methods alongside simulated gastrointestinal digestion and Caco-2 cell permeability assays, the authors likely demonstrate that oil-based processing improves micellarisation and intestinal absorption of β-sitosterol compared to raw garlic. The findings offer evidence-grounded support for classical Ayurvedic pharmaceutical practice of combining lipophilic herbs with fat-based vehicles to optimise nutrient bioavailability.

UK applicability

This study is conducted within an Ayurvedic pharmacological context in India and is not directly applicable to UK agricultural or dietary policy; however, the underlying findings on lipophilic phytonutrient absorption from garlic may be relevant to UK functional food research and dietary supplement formulation.

Key measures

β-Sitosterol concentration (µg/mg or mg/g); bioaccessibility (%); cellular uptake/permeability via Caco-2 cell lines; comparison of raw versus Taila-processed Lasuna

Outcomes reported

The study quantified β-sitosterol content in raw and oil-processed Allium sativum and assessed bioaccessibility and bioavailability using in vitro digestion and Caco-2 intestinal cell line models.
