Determination of total lipids and characterization of marigold flower extracts (Calendula officinalis)

Abstract

Bioactive extracts from marigold flower are important ingredients for parapharmaceutical and cosmetic preparations. Their antiflogistic holeretic.antimicrobic, antidermatic and anticancer effects are due to the presence of flavonoids, carotenoids, etheric oils, and terpenoids. This study presents the results of spectrophotometric investigation for the overall carotene content calculated as (3-caroten (442 nm), visual and physico-chemical characteristics according to Ph.Jug. V in oil extracts of marigold flower obtained by maceration (room temperature and 70?C) and percolation (room temperature) with olive oil and sunflower oil by original procedures.The largest content of (3-carotene (57.5 mg/kg of oil extracts) is in the oil extract obtained by maceration for 72 hours with olive oil (solvomodulus 1:5 m/m) at room temperature.
