“…This result aligns with the research of 26,27 , stating that the total phenolic content of methanol extract was more significant than the n-hexane fraction. It could be due to the polar nature of methanol, which could attract phenolic compounds well in the extraction process.…”

Propolis is one of the natural products produced by kelulut bees and is still not widely used. The type of stingless bee that is the prima donna in the community is Heterotrigona itama. This study aims to determine the phytochemical content of the n-hexane fraction of Heterotrigona itama bee propolis collected from Kutai Kartanegara, East Kalimantan. The n-hexane fraction was obtained from the methanol extract of H. itama propolis by the liquid-liquid partition method. After obtaining the n-hexane fraction, the research continued with a qualitative phytochemical test to identify the compound and determine total phenolic. Antibacterial activity was determined by the agar well diffusion method with a serial concentration in Escherichia coli bacteria. Qualitative phytochemical analysis in the form of color changes showed that the n-hexane fraction of H. itama propolis contained flavonoids, alkaloids, saponins, and tannins. Based on the results, the total phenolic content of the n-hexane fraction sample was 490 mgGAE/100 g. It caused the n-hexane fraction to have lower phenolic content than the methanol extract (792 mg GAE100 g). Furthermore, this result indicated that the non-polar fraction was not substantial enough to extracted phenolic compounds. It correlated to the antibacterial activity of the n-hexane fraction, which was very weak (2 mm ± 1.5) at 200µg/mL concentration.

Kombucha is a popular traditional tea prepared from different parts (leaves and flowers) of medicinal plants, including the leaves of telang (Clitoria ternatea L.). The fermented tea is usually flavoured with sugar. However, the concentration of added sugar affects the content of kombucha phytochemicals. Therefore, this study aimed to analyse the content of phenols and flavonoids and the antioxidant activity (DPPH) of telang flower kombucha sweetened with sugar. Three tea formulas were prepared with sugar concentrations of 20%, 30%, and 40%, respectively. The tea's total phenols and flavonoid contents and DPPH free radical scavenging activity were assessed using UV-Vis spectrophotometric analysis. The results showed an increase in total phenols and flavonoid contents after the fermentation process of telang flower tea into kombucha, from 87.2 to 110.8 ppm and 2.14 to 3.44 ppm, respectively. The highest phenolic content value of 129.6 ppm was obtained at 30% sugar (p<0.05). Results also show that adding sugar was directly proportional to the total flavonoid content (p<0.05). The antioxidant activity increased proportionally to 83.2 ppm at 30% sugar concentration, hence classified under the strong category (p>0.05). Based on the results, the fermentation process and adding sugar could increase the total phenols, flavonoids, and antioxidant activity in the formulation of telang flower kombucha.

“…Salah satu minuman herbal yang mulai naik daun saat pandemi adalah minuman ekstrak atau sari buah kurma. Jus Buah Kurma dan Sari Buah Kurma memiliki kandungan polifenol yang terbukti dapat meredam aktivitas radikal bebas (Elisya et al, 2017;Primurdia dan Joni Kusnadi, 2014). Kandungan antioksidan pada sari kurma adalah polifenol.…”

Covid-19 pandemic that is happening in Indonesia and throughout the world has caused changes in people’s eating habits. Food and beverages which can increase immunity become the main focus for the community during this pandemic. This study aimed to analyze the drinking habits on the immunity of SMA Muhammadiyah 25 Pamulang students. This study used a cross-sectional design. There were 78 subjects at the age of 16-17 years old who are 12th grade of SMA Muhammadiyah 25 Pamulang. Drinking habits were collected into 11 beverages types and divided into three categories (1: tea, coffee, and boba drinks; 2: fresh milk, powdered milk, sweetened condensed milk, ice cream containing milk, and yogurt; 3: date juice, honey, and traditional herbal medicine). Data were analyzed descriptively by applying the univariate test method. The results show that 66,67% of subjects consumed boba drinks more often. 32,05% of subjects always consumed coffee, and the last 39,74% of subjects rarely consumed tea. Furthermore, there are 62,82% of subjects more often consume ice cream, 25,64% of subjects constantly consume powdered milk, and 47,44% of subjects rarely consume fresh milk. Hereafter, there are 64,10% of subjects who always consume date juice. subjects often consume honey (47,44%) as well as traditional herbal medicine (46,15%). Subjects drink various beverages such as tea, milk, and their processed products, date juice, honey, and traditional herbal medicine to increase their immunity due to nutrient and antioxidant contents, to protect themselves from virus infection, including Covid-19.
