Abstract

The purslane plant has been designated by the World Health Organization as one of the most widely used medicinal plants in the world and is known as "Global Panacea". The diversity of purslane plants from the genus Portulaca amounts to about 40-100 species found in the tropics and in areas that have four seasons. Candidiasis is one of the most common fungal infections in humans. Candidiasis is an opportunistic infection caused by excessive growth of the genus Candida fungus, 70% of Candida infections are caused by Candida albicans. Research on the antifungal activity of the purslane plant P. grandiflora is still rarely done. This study aims to determine the effective dose of anticandidal activity of purslane herb (P. grandiflora) against the C. albicans test microbe. This research is an experimental study that includes in vitro biological testing with the disc diffusion method, namely testing the inhibition of the extract of P. grandiflora 20%, 40%, 60%, 80%, and 100% against the growth of the fungus C. albicans. The antifungal activity test was carried out by observing the diameter of the inhibition zone formed around the paper disk. Anti-candida activity test of purslane herb (P. grandiflora) magenta variety extract showed that there was a zone of inhibition that was significantly different between all treatment groups. The measurement of the inhibition zone in the treatment group with a concentration of 20 to 100%, respectively, was 6.33±20; 6.86±13; 7.59±21; 8.33±33; 9.66±21; 25.69±98, thus indicating a moderate inhibition category for the growth of C. albicans.

Abstract

Parijoto fruit (Medinilla speciosa Blume) is an endemic fruit around Mount Muria, Kudus, Central Java. The native people utilize Parijoto as traditional herbal medicine. Those utilization due to its metabolite compounds, such as tannin, flavonoid, fenolic, terpenoid, etc. In order to utilize Parijoto fruit properly, it is necessary to have an appropriate extraction and fractination method. So, the bioactive compounds of Parijoto fruit can be optimally extracted. The objective of this study is to obtain fractions of Parijoto fruit using three different solvent, methanol, ethyl acetate, and n-hexane. This study perform maceration as extraction method and liquid-liquid fractination to obtain the fractions. The dry simplicia yield was 85.49%. The maceration result was in the form of a blackish red green liquid with 67.45% yield. The methanol fraction was a thick blackish red liquid with 45.4% yield. While, the ethyl acetate fraction was a slightly fibrous viscous liquid with pinkish milk brown colour and 22.8% yield. On the other hand, the n-hexane fraction was a greenish viscous liquid with 13.8% yield. The highest yield is the result of fractination with methanol as a solvent because it is the most polar among others in this study. The solvent polarity is greatly affects the yield of fractination from natural product materials. In this study, the order of Parijoto yield from the highest to the lowest is methanol fraction, ethyl acetate fraction, and the last is n-hexane fraction. Those results were obtained due to the differences of each solvent polarity.
