紫苏醛

若以特征成分紫苏醛为紫苏质量的评价指标，本研究中的四个品系紫苏试材均不算优良食用紫苏品种。

If perillaldehyde was the evaluation index of perilla quality , the four test material were not the excellent edible variety .

花为淡紫色，植株全紫者（老叶叶面为绿色，叶背面为紫色）其挥发油的主要成分为紫苏醛，此植物为紫苏醛型。

As the flower is purplish and plant is purple , the main component of essential oil is perillaldehyde ( Perillaldenhyde type ) .
