説明

The time course of growth and content of saikosaponins (saikosaponin a, c and d) in the root of Bupleurum falcatum cultivated by sand culture system were investigated between October in 1994 and September in 1995.<BR>The plant showed a bimodal growth pattern. During the months of M3 and M4 (Mn ; n months after sowing), all plants were in a rosette form and the dry weight of both shoot and root increased gradually. After bolting started in M5, both parts of the plants grew exponentially. The dry weight of both parts reached a maximum at M9 when flowers bloomed on the main axis, and decreased significantly thereafter because the rosette leaves started to die and then leaves along main axis wilted successively from bottom to top. Axillary buds developed about one month later and the dry weight of both parts reached a second peak during the flowering of the axillary buds (M12).<BR>The content of saikosaponins in the main root during rosette form was higher when the plant was in the rosette form particularly at M4 than that during the remaining growth stages. The contents in the main root after bolting decreased during flowering (M9 and M12). However, change in the content of saikosaponins in the 1st-order and 2nd-order lateral roots and in the 3rd-order lateral roots differed significantly from those of the main root. The contents in the 3rd-order lateral roots was always lower than content in other roots throughout the culture period.
