Planta Medica, 1985
Two toxic principles of KALANCHOE DAIGREMONTIANA were isolated and structurally elucidated as bufadienolides with an unusual substitution pattern. Daigremontianin, a novel compound, and bersaldegenin-1,3,5-orthoacetate which was also found in KALANCHOE TUBIFLORA Hamet, show a pronounced sedative, positive inotropic and CNS-activity.

Gradient in the degree of Crassulacean acid metabolism within leaves of Kalanchoe daigremontiana
Planta, 1987Leaves of the Crassulacean acid metabolism plant Kalanchoe daigremontiana Hamet et Perr., about 3.3 mm thick, showed higher rates of net CO2 exchange through the lower than through the upper surface during day and night, although the lower surface received only a small fraction of the light which was incident on the upper surface.

ATP-Dependent Uptake of Malate in Vacuoles from CAM Plant, Kalanchoe Daigremontiana
1987Intracellular translocation of malate during crassulacean acid metabolism (CAM) is a complex phenomenon. The key enzyme phosphoenolpyruvate carboxylase catalyzes the synthesis of malate in cytoplasm has been established (Kluge and Tin, 1978). In the dark period the malate synthesized in the cytoplasm is transported into vacuoles and accumulated in its.
