- 165 Downloads
Cassia angustifolia (Tinnevelly senna) andC. acutifolia (Alexandrian senna) have great medicinal importance because of their sennoside content in leaves and pods, which are used as purgatives. Such properties have not been observed inC. occidentalis. The maximum growth of theseCassia species was observed in black soil followed by sandy and humus soils. The leaf pigments also increased in black soil. The sennoside content of senna was maximum in sandy soil as compared to other soils.
