Side effect of aceto-orcein as a dye of chromosome structures remains some risks. This dye may remain tissue damage on eyes mucous membrane, burnt by skin contact, severe irritation of respiratory by spray mist. Exploration of natural dye is an alternative solution. Betacyanine of red dragon fruits Hylocereus polyrhizus pulp might have a potential role to stain chromosome. Aim of this study is to extract dragon fruit pulp to stain chromosomes of mitotic cells of red onion Allium ascalonicum. The method used in this research is qualitative description of application squash method with aceto-orcein as synthetic dye and two ratio of extract ratio of red dragon fruits pulps as natural dye to mitotic cells of red onion roots. The result revealed that 2:1 ratio of red dragon fruits and distilled water could stain chromosomes of red onion somatic cells. Further specific solvent is required to further investigation to get best betacyanine extract of red dragon fruits pulps.

Lipstick is one kind of cosmetics which is used as lips colorant to increase self-confidence. Nowadays, lipsticks from natural source is popular to reduce the negative impact of chemical compound or synthetics colorant in lipstick intensively for health. Super red dragon fruit is one kind of natural ingredients which can be used as colorant for lipstick. Moreover, this fruit is rich of antioxidant and antibacterial component that is good for skin health. In this research, extract of super red dragon fruit flesh was added in the lipstick during preparation with variation of concentration 0, 10, 20, 30 and 40%. Antioxidant analysis resulted the IC50 value in 81.55% indicating the strong antioxidant properties. Furthermore, the concentration of dragon fruit extract 40% was able to inhibit the growth of Staphylococcus aureus bacteria.

  Objective: Indonesia is a country which has various natural resources including medicinal plants. Among the plants, red dragon fruit is interesting to be studied. In this study, antioxidant activity of red dragon fruit peel (Hylocereus polyrhizus (F.A.C. Weber) Britton and Rose) isolate was tested using 2,2-diphenyl-1-picrylhydrazyl method.Methods: Isolation of active compounds was performed through the application of vacuum liquid chromatography and preparative thin-layer chromatography (TLC). Antioxidant activity was tested using both TLC and spectrophotometry.Result: Results revealed that the values of IC50 of isolate 1 and 2 were 2.952, 14 μg/mL and 25.635,95 μg/mL, respectively.Conclusion: Isolate of dragon fruit has antioxidant activity. The compound which results in antioxidant activity is terpenoid and steroid.

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.

AbstractDragon fruit is a cactus species which is indigenous to Americas belongs to Genus Hylocereus. Dragon fruit is commonly known as Noble woman, Pitahaya, strawberry pear, Super fruit etc. It has antioxidant properties which prevents oxidation of cholesterol. Similarly, dragon fruit contains phytonutrient, minerals and vitamins which are beneficial to blood, tissue, bone and overall health. On research it was found out that Lycopene which is responsible for red colour in dragon fruit has been linked with a lower prostate cancer risk. Nowadays it is widely used in restaurant as fruit salad, refreshing drinks, Jams, Ice creams, Jelly, fruit juice, wine etc. In Nepal, Mr. Jagannath Rai brought dragon fruit from USA in 2057 B.S. and later Gorkha Millenium multipurpose cooperatives ltd formally started cultivation of dragon fruit in commercial level from 2070 B.S (2013 A.D). In Nepal there is a wide scope for cultivation as it can cultivate in region of less rainfall at altitude of 1500 from MASL. Availability of Fallow and marginal lands of Terai, Bhitri madhes, valleys and lower range of mountain are suitable for cultivation. Moreover, there are great possibilities of production of organic dragon fruits. Inspite of various benefits and possibilities, farmers’ condition and investment are major challenges for exploration of dragon fruit in Nepal.

Utilization of Trichoderma sp fungi as pathogenic fungi antagonists in red dragon fruit plants (Hylocereus polyrhizus) in vitro. The purpose of this study was to identify foul pathogens of dragon fruit plants and then test the ability of Trichoderma sp antagonists to deciduous pathogens of red dragon fruit plants in vitro. The study was conducted from August to October 2016, The research was conducted at the Laboratory of Pest and Plant Disease Sciences, Faculty of Agriculture, Mulawarman University, Samarinda. Sampling of plants exposed to foul tendrils was carried out in Bukit Merdeka Village, Samboja District, Kutai Kartanegara Regency. There are two data observed in this study, primary data and secondary data. Primary data is data obtained directly from the source through direct field observations and laboratory observations and secondary data data obtained from interviews with farmers. The results showed that the pathogen that causes tendon rot in dragon fruit plants is the fungus Colletotrichum gloesporioides (penz. Ssaac). Trichoderma sp can inhibit the development of pathogens Colletotrichum gloesporioides (Penz.) Ssaac., With the highest average resistance of 71.85%.
