Abstract

There have many benefits on the Artocarpus species have been used by traditional folk medicine in Indonesia against inflammation, malarial fever, stomachache, ulcers, abscesses, dysentery, diarrhea, defective urinary secretion, skin disease, and asthma. The plant parts contain flavonoids, triterpenic compounds, sapogenins, steroids and carotenoids. This research was undertaken to determine the effect of drying methods and particle sizes on yield of extraction on jackfruit leaves by using different ratio of water/ethanol solvent. This research also to screening the phytochemicals compound of TPC, DPPH radical scavenging activity, sterol and squalene in jackfruit leaves extract. In this research extraction of bioactive compounds and antioxidant activity from Artocarpus heterophyllus Lam’s leaves have been carried out using maceration technique. Result shown that the shortest time taken for drying by oven drying technique which is 23 hours to reach 9.89%. On top of that, the highest percentage of particle size distribution using sieve shaker for both drying methods are 64.56% for oven drying technique and 63.22% for shade drying technique on size between 150 and 250 µm. Furthermore, the highest percentage of extraction of jackfruits leaves is 40% by shade drying with 50% ethanol. Besides that, the highest total phenolic content is 372.3131±1.781 GAE mg/g by oven drying with 80% ethanol. On the other hand, DPPH radical scavenging activity gives the highest percentage which is 46.74% on oven drying with 50% ethanol. For sterol and squalene, shade drying with 100% ethanol gives the highest value of sterol and squalene which are 1.030±0.036 mg/g and 2.724±0.084 mg/g respectively
