Caffeic acid and rosmarinic acid are common components of Labiatae plants, such as shiso (Perilla frutescens Britton var. crispa W. Deane) and Boraginaceae plants. These compounds have various pharmacological activities, such as anti-inflammatory, anti-anxiety, and anti-depressive activities, but the content of these compounds in perilla has not been studied in detail. This study investigated the caffeic acid and rosmarinic acid contents of several pure strains in genus Perilla. Perilla plants cultivated under a certain set of conditions had different caffeic acid and rosmarinic acid contents. For example, their contents were higher in P. setoyensis (“Setoegoma”), suggesting that the genetic background of the species greatly affects caffeic acid and rosmarinic acid contents. Several strains of P. frutescens var. crispa were cultivated at the Experimental Station for Medicinal Plants, Graduate School of Pharmaceutical Sciences, Kyoto University and differences in their caffeic acid and rosmarinic acid contents were also observed. The total content of anthocyanins, which are closely related to the leaf color of perilla, was measured as cyanidin-3-glucoside equivalents, and a weak positive correlation was observed between the content of rosmarinic acid, and the total content of total anthocyanins. Furthermore, the results suggest that luminosity and photon flux density of light during cultivation can affect rosmarinic acid content.

紫苏属中的咖啡酸和迷迭香酸含量。

咖啡酸和迷迭香酸是唇形科植物的常见成分，例如紫苏（紫苏（Perilla frutescens Britton var。crispa W. Deane）和紫苏科）。这些化合物具有多种药理活性，例如抗炎，抗焦虑和抗抑郁活性，但未对紫苏中这些化合物的含量进行详细研究。本研究调查了紫苏属中几种纯菌株的咖啡酸和迷迭香酸含量。在一定条件下种植的紫苏植物具有不同的咖啡酸和迷迭香酸含量。例如，其含量在P. setoyensis中较高（“濑户egoma”），表明该物种的遗传背景极大地影响了咖啡酸和迷迭香酸含量。P. frutescens var。的几种菌株 紫苏是在试验站栽培药用植物，药物科学，京都大学，并在其咖啡酸差异和迷迭香酸含量的研究生院也观察到。花青素的总含量与紫苏的叶色密切相关，被测定为花青素-3-葡糖苷当量，并且在迷迭香酸的含量与总花青素的总含量之间观察到弱的正相关。此外，结果表明，培养期间光的光度和光子通量密度可能影响迷迭香酸含量。
