Abstract

Naturally, the human body has tolerance to free radical attacks. However, the natural antioxidant ability will decrease when exposure to free radicals from within and outside the body occurs intensively. Antioxidants play potential preventive role to protect the body from damage associated with oxidative stress by free radicals. One of the potential marine resources used as an antioxidant is macroalgae. Turbinaria is widely distributed in tropical waters of Indonesia, including West Kalimantan. This genus produces secondary metabolites with several biological activities. This genus abundantly grows in Kabung Island. However, it has not been used by the local community, even tends to be considered as a weed that disturbs others marine biota. This study aimed to evaluate the potential antioxidant activity of tropical brown macroalgae Turbinaria ethanol extract from Kabung Island, West Kalimantan. antioxidant activity was evaluated using the DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenger method with UV-vis spectrophotometer. The result showed that the ethanolic extract had a high of potential antioxidant activity which IC50 was 87.31 mg/L and it was classified into strong antioxidant potential.

Abstract

The many side effects of consuming chemical-based drugs in maintaining human health have led to a tendency to return to nature. Consumption of medicinal plants in fresh or dried form has been considered to minimize side effects. This research will examine the feasibility of cat's claw (Uncaria tomentosa Wild. Ex Schult) tea as a functional drink based on physicochemical parameters and total phenol content. The physicochemical parameters tested included pH, water content, ash content and organoleptic examination of herbal teas including taste, odor and color of the brewed solution, while the total content of phenolic compounds was carried out based on the Folin–Ciocalteu method. Organoleptic examination showed a characteristic odor of the leaves, such as the smell of herbal teas in general with a bland and astringent taste, and the juice of the solution was yellowish green. The results of the physicochemical parameter test showed that the pH of the solution was 6.9, the water content was 7.7, the ash content was 8.00%, while the total phenol content measured was 68.77 mg GAE/g sample.  The physicochemical parameters measured from the testing of cat's claw herbal tea in this study met the quality requirements of dry tea according to SNI No 3836 BSN 2013
