    摘要: PURPOSE: To provide a new plant extract that is extracted from barks of a plant in Phellodendron family and from defatted seeds of a plant in Croton family and shows excellent anticancer and immuno-potentiating effects practically without toxicity. CONSTITUTION: Barks of a plant in Phellodendron family (particularly Phellodendron anurense Rupr. is suitable) and defatted seeds of a plant is Croton family (particularly Croton tiglium (L) is suitable) are mixed, preferably at a weight ratio of 1/2-2/1 and treated with an organic solvent to remove the soluble components. Then, the new extract having properties shown in the table is extracted from the resultant mixture with water. This extract is useful as a medicine for treating diseases caused by defects in homeostatis of immune system and neurosecretory system.

    摘要: PURPOSE:To A cell activating substance composed of a water-soluble ingredient, extracted from Sophora angustifolia Sieb. et Zucc. of a leguminous plant and having a specific molecular weight. CONSTITUTION:Water in an amount of 5-10 times based on Sophora anguetifolia Sieb. et Zucc. is added thereto and the Sophora angustifolia Sieb. et Zucc. is dipped therein at 4 deg.C for several days while being occasionally stirred. A filtrate is then collected by filtration and concentrated until the volume attains (1/10) to (1/20) under reduced pressure. An organic solvent is added to the resultant concentrate so as to provide about 60% concentration thereof. Centrifugation is carried out to collect precipitates, which are then dissolved in water to perform gel filtration using a column (25X60cm) filled with, e.g. Sephadex G-25(R) and afford a fraction eluting at a specified Kav value, e.g. 0.65-0.86. The resultant fraction is subsequently freeze-dried to provide a cell activating substance having 700-1100 molecular weight. The obtained substance can be used as a promoter for tissue culture or regeneration and treatment of ulcerated and traumatic parts.
