Abstract

Forsythia viridissima Lindl. is a perennial woody plant for gardening, and its fruits have been used as herbal medicine. Changes in morphological characteristics and lignan components of fruits by Uiseong local germplasm of F. viridissima Lindl. and harvest time (from July to November) were investigated. Fruits have long ovate shapes and similar structures to sesame (Sesamum indicum L.) capsules, containing about 15.7 seeds. Across all 8 local germplasm, whole fruit weighs 0.12 g on average, 67% pericarp and 33% seed. Average content of arctigenin in whole fruit is 5.04 ㎎/g, showing the highest (5.99 ㎎/g) in FV10 line. The content of arctigenin in whole fruit is positively correlated with one of pericarp but lacks correlation with one of seed. In the study of the harvest time for fruits, fruit size was almost the same from July to November. Fruit weight increased from July (0.24 g) to August (0.29 g), remained similar till September (0.28 g), and then decreased with seed shattering. Arctigenin content decreased gradually from July (26.84 ㎎/g) to November (3.72 ㎎/g). Our results suggest that the pericarp in whole fruit is an important factor related to the fruit weight and arctigenin content, and the proper time to harvest fruits is in August, showing relatively higher weights of fruits and arctigenin content than in October.
