Preliminary phytochemical investigation, antioxidation and nitric oxide inhibition of Sugarcane and Toei-hom extracts for healthy drink applications

Abstract

Now a day, black sugar cane is popular as a healthy drink combined with pandan leaves to provide a good taste drink. Therefore, black sugarcane combined with pandan leaf tea should be studied for phytochemical composition and biological activity compared with ethanolic extracts. Therefore, the extraction by hot water as an herbal tea of black sugarcane mixed pandan leaf tea (BPT), black sugarcane tea (BT) and pandan leaf tea (PT), and the 50% ethanol extraction of black sugarcane extract (BE50) and pandan leaf extract (PE50) were investigated for phytochemicals, total phenolic compounds (TPC), total flavonoid compounds (TFC), total anthocyanin (TAC) content, antioxidant activities and nitric oxide (NO) inhibition. The results showed that the different TLC fingerprints were from different chemical compositions in each extract. The ethanolic extracts provided higher TPC TFC and TAC than the herbal tea extracts. Moreover, BPT has TFC and antioxidant activities similar to BE50. For nitric oxide inhibition, the highest %NO inhibition was from PE50. However, the black sugarcane drink mixed with pandan leaves tea (BPT) provided fewer active compounds than ethanolic extracts, but it could show antioxidant activity and NO inhibition that was beneficial to human body. This information was a scientific basis for further study and development of black sugarcane products.
