Abstract

Flavonoids are phenolic compounds widely distributed in plants and are well known for their antioxidant activity, which plays an important role in preventing degenerative diseases. One plant with potential as a flavonoid source is the globe amaranth flower (Gomphrena globosa L.), which has been traditionally used and reported to exhibit various pharmacological activities. This study aimed to determine the total flavonoid content of globe amaranth flower extract grown in Bali. Extraction was carried out using the maceration method with 96% ethanol at a ratio of 1:10, followed by remaceration. Phytochemical screening was performed to identify the presence of flavonoids, while total flavonoid content was determined using UV-Vis spectrophotometry with quercetin as the standard. Phytochemical screening confirmed the presence of flavonoid compounds in the extract. The determination of total flavonoid content showed a maximum wavelength at 433 nm, with a regression equation of Y = 0.0778X + 0.0012 and a correlation coefficient (r) of 0.9982. The total flavonoid content obtained was 81.808 mgQE/100 g extract. In conclusion, the globe amaranth flower (Gomphrena globosa L.) is a promising natural source of flavonoids and has potential to be developed as a raw material for traditional medicine, particularly as a natural antioxidant.

Abstract

Before the availability of a vaccine, Indonesian population relied on traditional medicines to prevent COVID-19. Any species used by indigenous people could lead to further investigations in modern pharmacology, to preserve ancient knowledge, and to plan for plants’ conservation. The study aimed to discover and record species, methods of preparation, route of administration, and motivation in using medicinal plants by the Indonesian population during the COVID-19 pandemic. Participants of survey were selected from the people who live in Java and Bali for responding to an online structured questionnaire. Relative Frequency of Citation (RFC) was employed in the quantitative analysis of the collected data. The pharmacological relevance of the five plants with the highest RFC was further reviewed. The results showed that respondents used 59 plants from 28 families. Five species with the highest RFC were Curcuma longa (0.707), Zingiber officinale (0.674), Cymbopogon citratus (0.269), Kaempferia galanga (0.174), and Curcuma zanthorrhiza (0.165). Most plants were prepared by boiling (77.97%) and administered orally as a single ingredient or mixed with other herbals. Respondents believed that the plants were beneficial as immune-booster (71.26%), maintain good health (24.85%) and stamina (12.28%), and prevent viral infection, including COVID-19 (5.39%). The most commonly used plants might be scientifically based to boost immunity. However, their usage against COVID-19 and the medicinal value of herbal mixtures should be further investigated.
