Introduction: The benefits of Imperata cylindrica (I. cylindrica) leaves and their relationship to the content of phytochemical compounds have been widely studied. The aim of this study was to promote I. cylindrica leaves from Kertajati Subdistrict in Majalengka Regency in their use as a medicinal plant based on the four parameters, namely the content of total phenolic content, total flavonoid content, total tannin content, and antioxidant activity. The four parameters that become the basis for the benefits of the leaves were compared with the four parameters of the roots. Methods: Quantification of total phenolic content, total flavonoid content, total tannin content, and antioxidant activity used Folin-Ciocalteu, aluminium chloride, Fe(III) chloride and 1.10-Phenanthroline, and 1,1-diphenyl-2-pikrilhidrazil (DPPH) methods, respectively. All methods used visible spectrophotometric method. Results: The percentages of total phenolic content, total flavonoid content, total tannin content, and IC50 of antioxidant activity of I. cylindrica leaves extract were 9\% (GAE), 2.1\% (QE), 5.6\% (TAE), and 100.5 ppm, respectively. Then, the percentages of I. cylindrica roots extract showed the percentages of total phenolic content, total flavonoid content, total tannin content, and IC50 of antioxidant activity were 5.8\% (GAE), 0.64\% (QE), 3\% (TAE), and 241 ppm, respectively. Conclusion: The extract of I. cylindrica leaves contained the phenolic compound, namely flavonoids, tannins and other phenolic compounds, and had antioxidant activity. All parameters have been reported to have positive effect on health. Therefore, the leaves of I. cylindrica from Kertajati Subdistrict are discovered to have effects on health which are suitable to be promoted as a medicinal plant.

Background: The storage roots of Pachyrhizus erosus (PE) have been traditionally used as a skin whitening agent in Indonesia and are also consumed fresh in many Southeast Asian countries, including Thailand. However, research on the biological activities of PE is limited. Objective: This study aimed to measure the total phenolic and flavonoid contents and to test the anti-tyrosinase and antioxidant activities of PE extracts. The Folin-Ciocalteu colorimetric, the Aluminium chloride colorimetric, the DPPH scavenging, and the Dopachrome assays were used for the experiments. Results: The dichloromethane extract had the highest anti-tyrosinase activity (IC50= 2.08 {\textpm} 0.40 mg/mL), total flavonoid content (9.93 {\textpm} 0.02 mg QE/g extract), and antioxidant activity (IC50= 40 {\textpm} 0.02 μg/mL). The largest total phenolic concentration was found in the 80\% ethanol extract, albeit (11.97 {\textpm} 0.55 mg GAE/g extract). Conclusion: Based on its remarkable activities, the dichloromethane extract is recommended for future development in skinlightening products. The study{\textquoteright}s findings conclude that PE extracts may be used as an alternate source of antioxidants and anti-tyrosinase agents

Objective: Excessive reactive oxygen species (ROS) often trigger the activation of elastase to degrade the elastin, an extracellular matrix (ECM) protein that provides resilience and elasticity of the skin. Therefore, the inhibition of elastase could reduce the wrinkles formation in the skin. Rumput teki (Cyperus rotundus L.) is used empirically to increase the skin elasticity but the scientific justification was still limited. This study aimed to determine the activity of Cyperus rotundus L (CyR) in inhibiting the elastase activity. Methods: Extraction of CyR was performed by maceration method using 70\% ethanol. The inhibition percentage and IC50 were determined by the colorimetric method using porcine pancreatic elastase (PPE) and N-Succ-(Ala)3-p- nitroanilide (SANA) as substrate. Phytochemical screening, determination of Total Phenolic content (TPC), and Total Flavonoid Content (TFC) were also performed to calculate the level of phenolic and flavonoid content in the sample. Results: The extract of CyR rhizomes contained TPC and TFC of 62.72 mgGAE/g and 10.72 mgEQ/g extract respectively and showed an inhibitory activity on elastase with IC50 of 178.72 μg/mL, smaller than IC50 of quercetin as reference drug (200.00 μg/mL). Conclusion: This finding suggested that extract of CyR rhizomes could be used as elastase inhibitor but the further research still needs to be developed.

Introduction: Electron Paramagnetic Resonance (EPR) spectroscopy is a unique technique able to identify and quantify free radicals in the complex biological matrices. In this study, free radical scavenging activity of aqueous and methanol extracts of fruits, shoots and roots of dill and parsley was examined using EPR technique, in addition to the determination of their contents of total polyphenols (TPC) and flavonoids (TFC). Method: The hydroxyl anion scavenging activity (HASA) of the tested extracts was determined using EPR spin trapping technique and hypoxanthine/xanthine oxidase system generating (O{\textbullet}-2). The TPC and TFC were determined using Folin-Ciocalteu and aluminum chloride colorimetric assays. Results: Both aqueous shoot of dill (ADSh) and methanol root of parsley (MPR) demonstrated the strongest inhibition of HASA. On the contrary, the aqueous extract of dill fruit at a concentration of 0.5 mg/ml was found to be pro-oxidant (49.43 \%), but at 10 mg/ml demonstrated potent inhibition of HASA (98.12 \%). TPC was found to be the highest in the methanol extract of parsley fruit (MPF, 88.62 {\textpm} 0.6 mg GAE/g) and the lowest in MPR (4.34 {\textpm} 0.050 mg GAE/g). On the other hand, TFC was the highest in MPF (584.29 {\textpm} 2.10 mg GAE/g) and the lowest in the methanol extract of dill fruit (MDF, 1.28 {\textpm} 0.02 mg rutin/g). Conclusion: In this study, EPR provided a direct insight that all tested apiaceous plants extracts showed effective HASA except two extracts that proved to be pro-oxidant at 0.5 mg/mL This study confirmed that there is no correlation between antioxidant potential and TPC and TFC.

Introduction: Accumulation of reactive species higher than permissible limits in biological systems may lead to various degenerative disorders due to oxidative damage. Materials and Methods: Oxidation is a serious concern faced by the food industry causing deterioration of shelved-food quality. Antioxidant compounds like polyphenolics scavenge such free radicals and thus protect against oxidative stress. Consumption of polyphenol-rich plants as dietary component confers protection against such cellular damage. Results: Present study explores antioxidant capacity, total phenolic content (TPC) and total flavonoid content (TFC) of different extracts prepared from various parts of Moringa oleifera Lam. Higher TPC, TFC and antioxidant activity was shown by methanolic extracts followed by aqueous, petroleum benzene and chloroform extracts.The present study suggests that all the extracts might act as radical scavengers to certain extent possibly due to presence of polyphenolic compounds. Conclusion: M. oleifera exhibits strong antioxidant activity and could serve as prospective source of natural antioxidants to food and health industries.
