Euphorbia milii cv., “The Crown of Thorns”, is a common species of Euphorbia that is widely distributed among different countries in Asia. Studies have indicated its toxicity against humans, and more studies have indicated its anti-oxidant, anti-mutagenic, anti-tumor and anti-cancer and many more of its biological activities. The researchers have come to recognize cancer as a prevailing cause of mortality worldwide, thus, this study aimed to determine the possible cytotoxic effect of Euphorbia milii cv. leaves on lung and colorectal cancer cell lines in order to provide a basis for upcoming similar researches.

Free radicals are atoms or molecules that have unpaired electrons which can cause numerous diseases. Antioxidants, on the other hand, are substances that inhibit the oxidation of free radicals. Lately, there is an increasing interest in antioxidants, particularly towards the antioxidant activity of Dragon fruit. Dragon fruit, which is also known as pitaya is the fruit of a night blooming cactus. The study aims to evaluate the total phenolic content and the radical scavenging activity of the white fleshed dragon fruit peel, red fleshed dragon fruit peel, and the combination of the white fleshed dragon fruit and the red fleshed dragon fruit. The dragon fruit peels were consecutively extracted with ethanol to produce dragon fruit crude extracts. The extracts were separately added with their respective reagents with 3 replicates of the three extracts each in the determination of Total Phenolics Content and DPPH free radical scavenging activity.
