Objectives: The goals of this research were to observe antioxidant properties from different parts of super red dragon fruit (Hylocereus costaricensis) using two antioxidant testing methods which were 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2’-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS).Methods: Antioxidant activities were determined using DPPH and ABTS assays, total phenolic content (TPC) using Folin–Ciocalteu reagent, flavonoid content by Chang’s method.Results: Inhibitory concentration 50% (IC50) of DPPH scavenging activity of all of the extracts in the range of 2.69 μg/ml was −94.17 μg/ml. The ethyl acetate peel extract of super red dragon fruit expressed the highest TPC (4.56 g GAE/100 g) and the highest total flavonoid content (12.63 g QE/100 g). TPC in flesh extract of super red dragon fruit had a negative and significant correlation with their IC50 of ABTS. The IC50 of DPPH and IC50 of ABTS of flesh extract of super red dragon fruit showed positive and significant correlation.Conclusion: All different parts extracts of super red dragon fruit (except n-hexane flesh extract) were categorized as a very strong antioxidant by DPPH method. Phenolic compounds in flesh extract of super red dragon fruit were the major contributor in antioxidant activities by ABTS method. DPPH and ABTS showed linear results in antioxidant activities of super red dragon fruit flesh extract.

Black ginger or is one useful medicinal plant that urges the need to be cultivated widely. This plant has some previous studies about their rhizomes and callus growth optimization, but their total content and antioxidant activities are not very . This study aims to study the total content and antioxidant activities of callus of K.. This study is to determine the type and concentration of hormone that give the best effect on the growth of callus in culture from different parts (, and basal part) of K.. Different concentrations were tested with medium 2,4-dichlorophenoxyacetic acid (2,4-D) and acid (NAA) in callus cultivation. The highest total content tested in callus is one with 10.00 mg/L 2,4-D from the part of the plant. The highest antioxidant activity is from the part of the plant with 5.00 mg/L 2,4-D.
