consists of a simple distillation process repeated a number of times. Soxhlet extraction method is straightforward and inexpensive. The sample phase is always in contact with fresh solvent, thereby enhancing the displacement of target compound from the matrix and the compound are not discomposed due to the moderate extraction condition.

In this research, works will be done to extract the antioxidant, specifically Vitamin C from red dragon fruit or also known as red pitaya. Red pitaya is a great healthy fruit to eat with lots of beneficial nutrients which are readily metabolized from the natural red pitaya fruit. Vitamin C in red pitaya is more easily absorbed than Vitamin C from a pill supplement. Lots of Vitamin C is in red pitaya. The amount of Vitamin C in red pitaya dried is 10 times more than amount of Vitamin C in fresh red pitaya.

Besides, red pitaya can helps to reduce levels of glucose in blood especially for diabetes patient. Other than that, the nutrient profile contained in red pitaya have full of dietary fiber, Vitamin C and even have a high level of antioxidant. These will enhance the nutritional value to our body particularly from the dried or fresh red pitaya fruit.

Identification of Problem

Everyday, our body easily exposed to mutated and oxidized cells, known as "free radicals". With a strong immune system, the human body can recognize and get rid of these cells. Cells can become mutated or oxidized naturally as they are replicating in the body, or from stress, smoking, age, and sun damage.

Our body has developed a natural way to rid off of these cells through the consumption and the use of natural antioxidants. The body naturally creates some antioxidants, but it relies heavily on a proper diet to get the rest of its natural antioxidants. Free radicals are the forerunners of devastating diseases like cancer,
