Calli from leaves and internodes are an important source of bioactive compounds with the capability to scavenge diverse free radicals, with potential as therapeutic agents for treating radical-related pathogenic cell damages. (22)
Forage Quality Index: Study evaluated the mimosine content and nutritive values of Neolamarckia cadamba and Leucaena leucocephala in comparison to Medicago sativa (alfalfa hay) as forage quality index. L. cadamba had low mimosine content (0.03%). Crude protein was 20.90%. Crude protein, crude fat, gross energy, protein to energy (P/E) ration, organic matter and total ash was higher compared to L. sativa. N. cadamba yielded higher nitrogen free extract, crude fiver and total ash than L. leucocephala. Results clearly indicate N. cadamba has high forage quality, comparable to traditional L. leucocephala and M. sativa as forage for ruminant and non-ruminants. (23)

Results showed intraperitoneal administration of chlorogenic acid (isolated from N. cadamba) to mice exhibited hepatoprotective action better than silymarin. The hepatoprotective activity was attributed to the antioxidative activity of CGA. (25)
