Abstract

Dillenia suffruticosa is one of the tropical medicinal plants that has been used traditionally for treating several tropical diseases. However, phytochemical and pharmacological investigations of D. suffruticosa wood bark have not been well-investigated. This research aimed to investigate the correlation between antioxidant properties and total phenolic content of phenolics rich extract and fractions from D. suffruticosa wood bark. The phytochemical investigation revealed the existence of phenolics and alkaloids in methanolic crude wood bark extract and all fractions. Meanwhile, the presence of flavonoids was shown in chloroform and methanol fractions. The highest total phenolic content was demonstrated by methanol fraction with 254.34 ± 16.86 mg GAE/g extract. Meanwhile, the highest total flavonoid content was interestingly displayed in chloroform fraction with 15.33 ± 0.26 mg RE/g extract. The crude extract and methanol fraction had a profound antioxidant activity with IC50 values of less than 15.63 ppm and 8.83 ppm, respectively. A strong correlation was shown between the antioxidant activity and total phenolic contents through correlation analysis. Thus, the D. suffruticosa wood bark could be considered a potential natural source of antioxidants.

Abstract

The current Covid-19 pandemic has had a very broad impact on various fields and levels of society, including education and students. Students are a group of people who are vulnerable to getting infected and becoming a COVID-19 transmitter. This Community Service activity aims to 1) Provide a deep understanding to students about covid-19 and how to prevent it. 2) Train students in making hand sanitizer and antiseptic and 3) meeting the basic needs of students affected by COVID-19. The methods used in this activity are: a) Dissemination of COVID-19 and how to prevent it. b) Assistance in the manufacture of antiseptic, including hand sanitizer and, disinfectant and, c) Providing assistance for staple food needs. Based on the results of this training activity, it shows that the participants have knowledge about what they can do to prevent the spread of Covid-19 by not traveling to places that cause crowds, always clean the boarding room or rented house with a disinfectant at least once a week and always use a hand sanitizer after having contact with objects in public areas and avoid direct physical contact such as shaking hands. Furthermore, participants have skills in making hand sanitizers and disinfectants through video tutorials made by the Community Service Team (PKM). In addition, participants were trained to maintain social distancing, especially at the stage of distributing staple food packages independently and eliminating crowds, washing hands before taking packages, measuring blood pressure, and checking body temperature.
