Ambrin
Abstract
The present study was conducted to investigate the elemental composition, nutrients and fatty acid profile of various parts of Oenothera biennis L in summer and winter seasons. Results showed Ca and Mg were high in leaves in winter and low in roots and stem respectively in summer. Iron was highest in fruits in summer and lowest in roots in winter. Zn was high in fruits and low in stem in summer. Fats were maximum in fruits in summer and minimum in roots in winter. Fibers were high in roots and less in stem in summer. Proteins were higher in fruit in summer and lower in stem in summer. Carbohydrates were higher in fruits in summer and lower in leaves in summer. The gross energy was higher for fruit in summer and lower for stem in summer. Myristic acid was greater in leaves in summer and absent in leaves in winter. Palmitic acid was greater in seeds and lesser in stem in summer. Stearic acid was greater in seeds while lower in leaves in summer. Arachidic acid was greater in leaves and absent in stem and roots in winter. Linoleic acid, linolenic acid, oleic acid and elaidic acid were also found in Oenothera biennis.
