Efficacy of an extract of UV-carotene carotenoids from marigolds. There are 3 main objectives: 1. Efficacy of the solvent used to extract calendula flower extract 2. The extraction of carotene from marigold and Boyd 3. Efficacy of extract. Carotene from marigold increases in radiation protection. UV
, solvents used to extract from marigolds are Acetone, Hexane and Ethanol on the solvent that is used to extract carotene carotenoids by Ben - Amotz and fishler method and extract cache. Roberto carotenoids were tested UV protection with type fibroblast cell culture and cell count was still alive to see effective protection from UV cell
research extracts from marigold. Found a solvent that can be extracted from marigold out the most Hexane and extracts from extraction by Ben - Amotz and fishler method to detect carotene carotenoids measured. the absorbance found. Marigold extract solvents Acetone and Ethanol contains carotene carotenoids exist. And when tested UV protection with cell culture and counting cell to live to see the effectiveness in preventing cell UV rays found that the extract carotene carotenoids from the solvent Acetone can prevent UV. best by a cell number of live cells remaining from the 9051 total of 10,000 cells.
