Bioaktivitas Ekstrak Etanol Biji Pinang (Arecha catechu L.) terhadap Staphylococcus aureus dan Escherichia coli

Abstract

Areca nut (Areca catechu Linn) is a plant that is widely distributed in tropical and subtropical regions. People have used it to treat various health problems. This study aims to determine the ability of betel nut ethanol extract to inhibit the growth of Staphylococcus aureus and Escherichia coli bacteria. The research method is experimental. Stages of research, first the betel nut is dried by aerating for 7-10 days. After drying, the seeds are ground into powder. The extraction stage of the active compounds uses the maceration method using 92% ethanol, evaporation is carried out using a rotary vacuum evaporator. The results of the maceration extract were carried out with phytochemical tests and bacterial inhibitory tests against E. coli, and S. aureus, carried out by the Kirby Bauer method. The detected metabolites were flavonoids, tannins and terpenoids. These metabolites have the ability as antimicrobials. The results of the inhibition test of the ethanol extract of areca nut seeds showed descriptively that the ethanol extract had a better inhibitory ability against S. aureus bacteria, compared to E. coli. The conclusion of this study is that the ethanol extract of areca nut seeds can inhibit the growth of E.coli and S.aureus.

In vitro and in silico study on the seeds of Veitchia merrillii on trematode worms

“…Ethanol extract of Jatropha curcas seeds inhibits Haemoncus contortus nematodes [17], while Allium sativum and Lawsonia inermis extracts exhibit fluidal activity against F. gigantica [18]. In Indonesia, most people have utilized areca nuts as an anthelmintic medicine [19][20][21][22][23][24][25][26][27][28][29]. The Veitchia merrillii, also referred as its areca nut family name Arecaceae [23,30,31], is a palm species.…”

Electric Mosquito Repellent Effect of Male Breadfruit Flower Mat Causes Mosquito Mortality Anopheles sp.

“…mosquito population. because the biological method does not use chemicals but contains plant phytochemicals which have the ability of vegetable larvicidesor mosquito repellent (Asrianto et al, 2023).Breadfruit is a plant that is spread evenly because it can grow almost all over Indonesia. This plant produces female flowers (fruits) which are usually used as food because the flesh of the fruit is thick so it can be eaten (Sumadji et al, 2022).…”
