MALDONADO-SANTOYO, María  e  MORALES-LOPEZ, Gladys. Chemical and nutritional Analysis in leaves of Ricinus communis. Rev Cub Quim [online]. 2022, vol.34, n.1, pp. 3-18.  Epub 18-Fev-2022. ISSN 2224-5421.

The objective of this work was to identify some bioactive compounds present in the leaves of Ricinus communis. For this, healthy leaves were collected, which were washed, dried and pulverized. Subsequently, its primary phytochemical analysis was carried out and its chemical composition was quantitatively evaluated. The presence of tannins, steroids, terpenoids and saponins were identified. The content of carbon, nitrogen and sulfur was 42,03; 5,33 and 0,43 %, respectively. The proximal analysis revealed a content of crude protein (33,31 %), crude fiber (5,97 %), lipids (3,71 %), ash (9,63 %) and the presence of some macrominerals. Flavonoids such as quercetin (2,28 %), myricetin (0,82 %), and kaempferol (0,22 %) were identified. Essential amino acids such as lysine, methionine, threonine, leucine, isoleucine, valine, arginine and glutamic acid were found (0,55-3,61 %). Ricinus communis leaves are a raw material, rich in various bioactive compounds of nutritional and commercial interest.
