The bitter principle in the radicchio is lactucopicrin (intybin) , a sesquiterpene lactone. Lactucopicrin is a potent anti-malarial agent and has a sedative and analgesic (painkiller) effect. Its leaves are an excellent source of phenolic flavonoid antioxidants such as zea-xanthin, and lutein.
It typically takes two years to get an associate degree, but depending on the program and your own schedule it may take more or a bit less.
A master's degree is a graduate degree and also takes about 2 years, but you'll need a bachelor's degree first before you can get a master's. Which is better depends a little on what you want to do with your degree. An associate's degree is 60 credits. Going full time (5 classes per semester), that takes two years.
