Abstract
Some plants whose leaves can be made into green grass jelly are Cyclea barbata (Cincau rambat bulu), Premna oblongata Miq (Cincau perdu), and Cocculus orbiculatus (Cincau jelly). However, the percentage of the content contained in each plant leaf is not necessarily the same. This study aims to determine the percentage of chlorophyll, flavonoids, dietary fibre, and water content from these three fresh leaves planted by researchers in Semarang. The analysis of chlorophyll content using spectrophotometry method with a 663 nm and 645 nm wavelength. The analysis of flavonoid content using the spectrophotometry method with a 420 nm wavelength. The study of dietary fibre content using the multienzyme method. And the analysis of water content using the heating method. Cyclea barbata leaves have the highest chlorophyll (9.806%) and flavonoids (0.1054%) content of all, while Premna oblongata Miq leaves have the highest water content (79.3370%) and dietary fibre (12.5125%) content of all.
