Phycocyanin was extracted from using conventional extraction (CE), direct ultrasonic-assisted extraction (direct UAE), indirect ultrasonic-assisted extraction (indirect UAE), and microwave-assisted extraction (MAE) methods at different temperatures, extraction intervals, stirring rate, and power intensities while maintaining the same algae to solvent ratio (1:15 ). The optimization of the extraction parameters indicated that the direct UAE yielded the highest phycocyanin concentration (29.31 ± 0.

- - Grape marc, a by-product from winemaking, contains beneficial compounds that can be extracted and used to create sun protection creams, specifically using polyphenolic extracts from different grape varieties like Merlot and others.
- - The best extraction method was found to be 70% ethanol in water, with Merlot extracts showing the highest sun protection factor (SPF) of 7.83 ± 0.76.
- - When formulating the sunscreens, the cream made from the aqueous extract of Merlot achieved an SPF of 14.07 ± 1.50, demonstrating better stability compared to creams made from ethanolic extracts.
