Physiological Activities of Perilla Frutescens Var. Frutescens Leaf Extracts and Storage Stability in Kneaded Noodles

Antioxidant activities of polyphenols extracted from Perilla frutescens varieties.

Various cultivars of Perilla frutescens (L.) (var. crispa and var. frutescens) Britt. were harvested in China and Japan. They were easily differentiated on the basis of their foliage color, that varied from red to green. Water extracts of dried plants were investigated for their antioxidant activity (AA) and their polyphenolic compounds compared. Among them, cinnamic acid derivatives (coumaroyl...

Anti-inflammatory Effect of Perilla frutescens (L.) Britton var. frutescens Extract in LPS-stimulated RAW 264.7 Macrophages

This study was designed to investigate the inhibitory effects of Perilla frutescens (L.) Britton var. frutescens extract on the production of inflammation-related mediators (NO, ROS, NF-κB, iNOS and COX-2) and pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) in lipopolysaccharide-stimulated RAW 264.7 macrophages. Perilla frutescents (L.) Britton var. frutescens was air-dried and extracted with e...

Phytochemical study of polyphenols in Perilla Frutescens as an antioxidant

Perilla frutescens is an annual herb of the mint family native to East Asia. Polyphenols present in perilla have various structural varieties with large diversity of biological activities. It is direct influence the quality of perilla plant and their potential functions. Some of these products have been studied and proven to be effective source of phenolic antioxidants. The aqueous extract cont...

Optimization of Antibacterial Activity of Perilla frutescens var. acuta Leaf against Staphylococcus aureus Using Evolutionary Operation Factorial Design Technique

This study was undertaken to optimize extraction using evolutionary operation-factorial (EVOP) design technique to elicit the antibacterial activity of Perilla frutescens var. acuta leaf against Staphylococcus aureus ATCC6538. Higher antibacterial activity was achieved at higher extraction temperature and over a longer extraction time. Antibacterial activity was not affected by differentiation ...
