Abstract

Seasonal Variation In The Content Of Sennosides And Rhein In Leaves And Pods Of Cassia Fistula

Author(s): Anusree Dutta, D. E Bratati

The seasonal variations of sennoside and rhein content (both glycosidic and non-glycosidic) in leaves and pods of Cassia fistula grown in Calcutta, India was studied. In the leaves, both these anthraquinone glycosides remain high in the mature and old leaves in the months from January to April when the contents of mature pods are low. In the developing green pods the content is high compared to the older ones, while the young leaves have lower glycosidal content compared to their mature stage. In general, leaves are a richer source of these glycosides.
