VARIATIONS IN THE YIELD OF TOTAL AND INDIVIDUAL 25α– AND 25β–SAPOGENINS ON STORAGE OF WHOLE SEED OF TRIGONELLA FOENUMGRAECUM L.

Abstract

Commercial whole seed of Trigonella foenumgraecum L., of Ethiopian origin, was stored for 133 days at temperatures of 5°, 28°, 27°, 18–25° and 26–30°. Rhythmic changes occurred in the 25α– and 25β–steroidal sapogenins and in their total. In this experiment the rhythm appeared to be inherent and affected only by low temperature.
