Abstract

  Infectious diseases by bacteria are one of the problems in the world of health. The therapy that can be given to people with bacterial infections is antibiotics. However, the increasing incidence of antibiotic resistance and bacterial infections requires other antibiotic alternatives such as those sourced from natural materials. Bay leaf (Syzygium polyanthum (Wight) Walp) included in the Myrtaceae family is one of the plants that is widely known among Indonesian people which empirically has properties in curing various diseases. Bay leaves are known to contain secondary metabolite compounds such as flavonoids, tannins, alkaloids, saponins, triterpenoids, steroids, eugenol, and essential oils that function as antibacterials. This literature review aims to discuss the antibacterial activity of bay leaves against gram-positive and gram-negative bacteria as well as the components of active compounds in bay leaves and their mechanism as antibacterials. The method used in the preparation of this review article is the literature study method. This research uses secondary data taken from the results of other researchers' research in the form of scientific articles that have been published in national and international scientific journals with a year limit from 2014 to 2023. Based on the literature study that has been done, it is known that bay leaves have potential as antibacterials against both gram-positive and gram-negative bacteria. The antibacterial activity is known to be related to the content of active compounds such as flavonoids, tannins, alkaloids, saponins, triterpenoids, steroids, phenols, and essential oils.

Abstract

Cascara refers to the dried husk of coffee cherries. It has garnered significant attention in recent research due to its phytochemical composition and potential health benefits. Several studies have highlighted the presence of bioactive compounds and the antioxidant activity exhibited by cascara. This study aims to investigate the phytochemical content and antioxidant potential of cascara. The cascara was extracted using the maceration method with 96% ethanol, followed by phytochemical screening for alkaloids, flavonoids, tannins, saponins, terpenoids, steroids, and quinones using standard color reactions in test tubes. Antioxidant activity was assessed via the DPPH (2,2-diphenyl-1-picrylhydrazyl) assay, with ascorbic acid as a reference compound. The phytochemical profile of the extract was identified using gas chromatography-mass spectrometry (GC-MS). The findings indicated that cascara contains alkaloids, flavonoids, tannins, saponins, and triterpenoids. GC-MS analysis identified caffeine, hexadecanoic acid (methyl ester), and hexadecanoic acid (ethyl ester) as the predominant compounds in cascara. The antioxidant activity test using the DPPH method demonstrated that the ethanol extract of cascara possesses moderate antioxidant potential, with an average IC50 value of 108.49 ± 1.28 ppm. Ascorbic acid, the reference compound used in this study, yielded an IC50 of 2.53 ppm, categorized as very strong. This research underscores cascara’s potential as a valuable source of antioxidants with significant health benefits, influenced by geographic factors affecting its bioactive compound profile. Consequently, cascara holds promise for further development as a raw material for functional health-promoting products.

Abstract

Pomelo peel (Citrus maxima) is an agricultural by-product rich in bioactive compounds, particularly flavonoids and phenolic compounds, which have potential antioxidant and anti-aging properties. However, the high pectin content in citrus peels can hinder the release of these active compounds. The objective of this study was to improve the extraction efficiency of bioactive compounds from pomelo peel using an environmentally friendly Enzyme-Assisted Extraction (EAE) method employing pectinase enzymes and to formulate the extract into instant effervescent granules. The granules produced using enzymatic extraction, granules prepared without enzymes, and control granules were evaluated through sensory assessment, physical quality analysis, total phenolic content, antioxidant activity (DPPH method), and crude fiber content. The results showed that enzyme-assisted extraction granules (EEG) exhibited significantly higher free radical scavenging activity (49.57 ± 6.10%) compared to non-enzymatic granules (NEG) (28.48 ± 8.67%). EEG also demonstrated a higher total phenolic content (0.027 g/100 g) than NEG (0.017 g/100 g). In addition, EEG showed better sensory acceptance and physical quality, including a more balanced taste, a stronger citrus aroma, and higher fiber content. These findings indicate that the application of the EAE method can enhance phenolic and fiber content, physical quality, and antioxidant activity of instant pomelo peel granules, suggesting their potential development as an environmentally friendly natural antioxidant product.

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.
