title = "Optimization of phycocyanin extraction from microalgae Spirulina platensis by sonication as antioxidant",
abstract = "Cardiovascular disease is known as an epidemic disease which has high casualty in the world. One of its trigger factors is the amount of reactive oxygen species (ROS) inside the body. In order to regulate its amount, antioxidant ingestion is compulsory. Microalgae can be adopted as a source of antioxidant. Spirulina platensis is one of the consistently produced microalgae. It contains phycocyanin, a blue pigment, which is known as a nutritious food agent. Phycocyanin could be assumed as an antioxidant and has been clinically validated both in vitro and in vivo. This research is proposed to determine the optimum extraction time. The experiment was conducted by sonication at 37 kHz using phosphate buffer as the solvent. The result exhibited that increasing the sonication time would increase the yield until it achieved the optimum yield. Based on the experiment, the optimum extraction time was 25 minutes with yield of 8.25 mg/g dry biomass and purity of 0.6. It can be summarized that extraction time also affected the extraction efficiency and its antioxidant activity. This paper shows a prospect on future development in cultivating micro flora in Indonesia, particularly in Depok.",
