Leaf-opening substance of a nyctinastic plant, Cassia mimosoides

1, isolated from Cassia mimosoides L., was quite effective for leaf-opening of the plant 4 × 10 −6 M at night. Two inversely effective leaf-movement factors, 1 and 2, were isolated from the same plant. Calcium 4- O-β- d-glucopyranosyl-(Z)- p-coumarate, isolated from Cassia mimosoides, was effective...

Description
Summary:1, isolated from Cassia mimosoides L., was quite effective for leaf-opening of the plant 4 × 10 −6 M at night. Two inversely effective leaf-movement factors, 1 and 2, were isolated from the same plant. Calcium 4- O-β- d-glucopyranosyl-(Z)- p-coumarate, isolated from Cassia mimosoides, was effective for leaf-opening of the plant 4 × 10 −6 M at night. This leaf opening substance and potassium chelidonate, which is a leaf-closing factor isolated previously, were inversely effective for the leaf of Cassia mimosoides.
