Abstract
The present study aimed to determine the effects of ingesting perilla oil derived from the seeds of Perilla frutescens as an inclusion complex with γ-cyclodextrin (γ-CD) in a six-week study, and to elucidate the role of γ-CD in the assimilation of perilla oil. Plasma α-linolenic acid (18:3n-3) levels were significantly higher in rats fed a diet containing this inclusion complex compared to those fed the same amount of perilla oil without γ-CD, indicating that γ-CD enhances perilla oil bioavailability. An in vitro analysis of lipolysis revealed that perilla oil was more resistant to porcine pancreatic lipase than soybean oil, a commonly used lipid source in animal diets. However, adding γ-CD accelerated perilla oil lipolysis, which may explain the elevated 18:3n-3 plasma levels in rats fed the inclusion complex. These findings suggest a more efficient way to increase physiological levels of 18:3n-3 and longer n-3 fatty acids when ingesting perilla oil.
