Perilla frutescens is a food plant widely used in Asian cuisine. This plant was investigated for its interesting taste and somatosensory properties. Perillaldehyde and perillaketone are among the components of the aromatic extracts from P. Frutescens. These compounds were shown here to activate the cloned TRPA1 channel when expressed in an heterologous cell system and are therefore suggested to be responsible for the chemesthetic properties of this plant.

This comprehensive review explores the biological functions of seed proteins and peptides, highlighting their significant potential for health and therapeutic applications. This review delves into the mechanisms through which perilla peptides combat oxidative stress and protect cells from oxidative damage, encompassing free radical scavenging, metal chelating, in vivo antioxidant, and cytoprotective activities. Perilla peptides exhibit robust anti-aging properties by activating the Nrf2 pathway, enhancing cellular antioxidant capacity, and supporting skin health through the promotion of keratinocyte growth, maintenance of collagen integrity, and reduction in senescent cells.

Rosmarinic acid (RA) is a natural active compound widely found in many plants belonging to the family of , , and so on, which has various important bioactivities, including being anti-oxidative, anti-inflammatory, antiviral, etc. Herein, novel hydrophilic magnetic molecularly imprinted polymers (HMMIPs) with a regular core-shell structure were successfully developed using RA as a template molecule, acrylamide (AM) as a functional monomer, N-N 'methylenebisacrylamide (MBA) as a cross-linking agent, and water as the porogen. After a series of characterization and adsorption performance analyses, it was found that HMMIPs are hydrophilic with an adsorption capacity of 8.

: Perillyl alcohol (POH), a monoterpene natural product derived from the essential oils of plants such as perilla (), is currently in phase I and II clinical trials as a chemotherapeutic agent. In this study, we investigated the effect of POH on cytochrome P450 (CYP) activity for evaluating POH-drug interaction potential. : The investigation was conducted using pooled human liver microsomes (HLMs), recombinant CYP3A4 (rCYP3A4) enzymes, and human pluripotent stem cell-derived hepatic organoids (hHOs) employing liquid chromatography-tandem mass spectrometry.
