Premna serratifolia, commonly known as Arogo in Tentena-Sulawesi, is a popular vegetable. As a promising herbal tea and food ingredient, further investigation is required to find the best knowledge for medicinal use of P. serratifolia leaves. This research investigated the antioxidant activity of the ethanol (EEPS) and water (WEPS) extracts of P. serratifolia leaves, based on their scavenging activities on DPPH radicals and their reducing capacities (CuPRAC, total antioxidant/phosphomolybdenum, and ferric thiocyanate reducing power assays). The DNA-protecting effect by EEPS was tested using pBR322 plasmid DNA against •OH radical-induced damage. The inhibition potentials of both extracts against several enzymes related to metabolic diseases (α-glucosidase, α-amylase, xanthine oxidase, and protease) were evaluated. The phytochemical analysis was conducted by an LC-QTOF-MS/MS technique. EEPS proved to be a better antioxidant and had higher phenolic content compared to WEPS. EEPS demonstrated a protective effect on DNA with recovery percentage linearly correlated with EEPS concentrations. Strong inhibition on α-glucosidase and α-amylase was observed for EEPS; however, EEPS and WEPS showed weak inhibitions on xanthine oxidase and protease. LC-QTOF-MS/MS analysis identified seven main components in EEPS, namely scroside E, forsythoside A and forsythoside B, lavandulifolioside, diosmin, nobilin D, campneoside I, and isoacteoside. These components may be responsible for the observed enzymes inhibitions and antioxidant properties. Premna serratifolia leaves can be an appropriate choice for the development of nutraceutical and drug preparations.

The world is observing an unprecedented development in the usage of herbal product at national as well as international levels. This requires the improvement of current and aimed standards for estimating the quality, safety and efficacy of these drugs. The leaves of Ailanthus excelsa and the fruits of Randia Dumetorum are medicinal plants that are used for many diseases around the world. We then collected the flavonoids and saponin fraction extracted from the leaves of Ailanthus excelsa and the fruits of Randia dumetorum. To determine the reliability, quality and purity of these particles, we provide a crucial pharmacological profile along with the antioxidant activity. Pharmacological studies, such as morphological, physicochemical, TLC, and phytochemical analysis of all fractions containing total phenol and flavonoids, were performed according to specific methods. DPPH tests estimated the antioxidant action of all fractions, Hydrogen peroxide scavenging assay, and reducing power assay method. Previous phytochemical studies discovered the occurrence of saponins, flavonoids, tannins, and especially phenolic chemicals. All fractions have antioxidant effects, depending on the existence of a phenolic compound. The above parameters are vital to establishing pharmacological rules for the authentication of Ailanthus excelsa leaves and Randia Dumetorum fruits.
