Is It True That Chili Pepper Got A High Concentration Of Vitamin C?

Unfortunately the answer to this question is no. :) (Unless you got another paper which says yes).

How so? This means that you need to eat at least 10 percent of a kilo of chili pepper fruit just to get half the amount of an ordinary vitamin C tablet (500mg per tablet concentration).

Vitamin C is an important water soluble vitamin that our body needs in order to do some basic bodily repair and serve as an antioxidant. Please see other related articles on Vitamin C, Can Too Much Vitamin C Cause Kidney Stones? and  How Much Vitamin C Do We Really Need?

Vitamin C is naturally occurring to both plants and animals.   Here is the summary of fruits/vegetables/animals with their corresponding vitamin C content in terms of milligrams of vitamin C per 100 grams (taken from Wikipedia).

The highest is Kakadu plum (3,100mg/100g of fruit), followed by Camu Camu (2,800 mg/100g), Rose hips (2000mg/100g), on the ninth place is Green chili pepper (244mg/100g), 12th and 13th place goes to Red pepper (190mg/100g) and Red chili pepper (144mg/100g).  There are 73 plants/vegetables/fruits overall on the list (for the complete list, please click Wikipedia).
