The five selected flowers are divided into five different families: Apocynaceae, Boraginaceae, Fabaceae, Cucurbitaceae and Malvaceae. The colors of the selected flowers are varying from yellow to red. In this work the carotenoid pigments were extracted, separated and identified and quantified for their potential use as low-cost and abundant sources in the food industries.The majority methods of extraction of carotenoids from plant sources make use of organic solvents such as hexane, ethanol, methanol, tetrahydrofuran, benzene, and petroleum ether. It has been observed that the stability of carotenoid extract obtained with hexane, acetone, ethanol was higher than that of extracts obtained with other organic solvents, such as chloroform, methanol or dichromate. The proposed work was done by Soxhlet method and all metrics were analyzed by high performance factor Concentration of β-carotene (μg/g).

Flowers have long held an important role in human societies. They have been used for ornamental purposes as well as in diverse dishes, mainly due to their appealing and diverse colours. In addition, flowers have been used in traditional medicine. In recent years, there has been a growing interest in the study from different points of view of the health- promoting secondary metabolites present in flowers, including carotenoids and phenolics Flowers inherit their appearance from genes. Flower colour is one of the most important traits of ornamental plants and is attributed to various pigments. As a plant looks aesthetic, the colours of a flower must attract us first. Therefore the brighter the flower, the more likely it will be visited .Plants have a number of different means to attract pollinators, with bright showy colours being one of the most common ways to maximize their visual effect. While other flower features, such as texture and fragrances, are also used to attract pollinators, a plant’s colour is vital to its survival from one generation to the next. The colour observed in flowers is actually the result of reflected light from various chemical compounds called “Plant Pigments”. Pigments are born into these plants, producing a range of colours across the spectrum. There are many different plant pigments, and they are found in different classes of organic compounds. The selective absorption of different wavelength determines the color of a pigment. The molecular
