“…Antibacterial properties assays were conducted as previously reported Salni & Marisa, 2020) with slight modifications. The essential oil of the leaves and fruit of A. monopleura was tested for its ability to inhibit the growth of Staphylococcus aureus ATCC 25023 and Escherichia coli ATCC 35218.…”

Alpinia monopleura is an endemic plant which widespread and abundant in Sulawesi. Nevertheless, previous studies have not studied the chemical compound and biological activity. This study describes the chemical compounds and antibacterial and antioxidant properties of the essential oils isolated from A. monopleura. The essential oil was obtained by the hydro distillation method and interpreted by GCMS. Antibacterial properties were determined by the agar diffusion method, while DPPH and ABTS determined antioxidant activity. The most important components are α-caryophyllene, β-pinene, limonene, α-pinene, β-caryophyllene and caryophyllene oxide. Essential oils of leaves and fruit showed excellent antibacterial properties with a MIC strength of 31.3 μg/mL against Staphylococcus aureus ATCC 25023 and Escherichia coli ATCC 35218. The highest antioxidant effect was also shown by inhibiting ABTS and DPPH radicals, with IC50 strength of essential oil obtained from the leaf being 15.60 and 19.42 μg/mL, respectively, while from the fruit were 10.44 and 11.93 μg/mL. These antibacterial and antioxidant properties indicate that essential oils have advantages in their use in the food and pharmaceutical industries.

WHO will announce the end of the Covid-19 pandemic, but the use of hand sanitizer is likely to become a positive new habit. Frequent use of hand sanitizers can cause effects, including dry hands, and even some people experience allergies to the skin of their hands due to the high alcohol content. It is necessary to look for alternative natural ingredients that do not have side effects but still have effective benefits. The research method begins with the manufacture of ethanol extract and aqueous extract of Piper crocatum and Alpinia galanga. All extracts were made into 5%, 10%, 15%, 25%, and 50% and then into a liquid soaking carp meat pieces that had been put into a test tube. Positive control used alcohol and sterile aqua. The ethanol extract of Piper crocatum 50% and 25% and the ethanol extract of Alpinia galanga 50% and 25% which had the best antimicrobial ability on day 19. The phytochemical test results showed that the ethanol extract of Piper crocatum contained alkaloids, tannins, steroids, and titerpenoids. Phytochemical test of ethanol extract of Alpinia galanga contained flavonoids, tannins, steroids, and titerpenoids. In conclusion, the ethanolic extract of Piper crocatum 50% and then 25% had the best antimicrobial ability, followed by the ethanolic extract of Alpinia galanga 50% and 25%. In the next stage, the best ethanol extract will be tested for microbes in a petri dish, before being used as a raw ingredient for hand sanitizer.

Rose myrtle, or (Rhodomyrtus tomentosa [Ait.] Hassk), is a plant that belongs to the Myrtaceae family. The rose myrtle plant is one of the biodiversity that must be developed sustainably because of its properties as an antidiabetic, diarrhea, burns, bleeding wounds, and stomachaches. Rose myrtle leaves contain rhodomyrtone antibiotic compounds. The rhodomyrtone compound belongs to the phloroglucinol derivatives and active against Escherichia coli and Staphylococcus aureus [5]. Rose myrtle leaves have been used by society to treat various diseases related to bacterial infections, such as dysentery and typhoid fever caused by S. dysenteriae and Salmonella Typhi. The antibacterial test results showed that n-hexane and ethyl acetate extracts were active against both bacteria, while ethanol extract was not. Isolates N1 and E1 were produced, respectively, from n-hexane extract and ethyl acetate extract. The MIC values of both N1 and E1 for S. dysenteriae and S. Typhi were the same, namely, 125 μg/mL. Isolate N1 was an essential oil containing menthol (59.60%), caryophyllene (25.77%), and cubenol (14.63%), while isolate E1 was essential oil containing (73.93%), pentanone (8.30%), alpha calacorene (7.58%), and calacorene (3.78%) [6].The application of rose myrtle leaves as traditional medicine needs to be proven for its efficacy and safety.
