Abstract
The pineapple (Ananas comosus L. Merr.) is a tropical fruit in the Bromeliaceous family, with a short stem and thin, stiff leaves that grow into medium- to large-sized fruit. The pineapple has special qualities, and only the fruits are eaten because of how sweet they are. The plant’s other components are frequently discarded, representing a substantial loss of potential value. The purpose of this investigation was to evaluate the proximate and phytochemicals of pineapple crown to ascertain their compositions utilizing conventional analytical procedures. Proximate analysis revealed that the pineapple crown is a rich source of carbohydrates (52.45%) and die-tary fiber (25.54%), alongside appreciable levels of protein (8.86%), ash (5.08%), and moder-ate fat content (4.63%), yielding an energy value of 286.91 kcal/100g. These findings show its suitability for nutritional applications, such as animal feed supplementation or as a functional food ingredient. The screening of phytochemicals showed that tannins, alkaloids, flavonoids and terpenoids were present while steroids, phenol and cardiac glycoside were absent. Quanti-tative analysis further elucidated significant concentrations of these compounds, with alkaloids at 6.23%, saponins at 4.68%, and flavonoids at 1.66%. The presence of these phytochemicals highlights the crown’s promising medicinal attributes, including antioxidant, antimicrobial, and anti-inflammatory properties. The findings show that pineapple crown contains different levels of nutritional components. The presence of medicinally important bioactive constituents in the crown is a potential source of metabolites for pharmacological, functional dietary, and medici-nal uses.
