Terpenoids and Phenylpropanoids in Ligularia duciformis, L. kongkalingensis, L. nelumbifolia, and L. limprichtii.

The diversity in root chemicals and evolutionally neutral DNA regions in the complex of , , and (the d/k/n complex) was studied using eight samples collected in central and northern Sichuan Province of China. Cacalol () and epicacalone (), rearranged eremophilanes, were isolated from the complex for the first time. Two new phenylpropanoids were also obtained.

The motility of Chara corallina myosin was inhibited reversibly by 2,3-butanedione monoxime (BDM).

We studied the effects of 2,3-butanedione monoxime (BDM) on the cytoplasmic streaming of Chara corallina and on the motility of myosin prepared from the same plant to examine whether this reagent really affects the plant class XI myosin. It was found that BDM inhibited both cytoplasmic streaming and the motility of myosin at a very similar concentration range (10-100 mM). BDM introduced directly into tonoplast-free cells also inhibited cytoplasmic streaming.
