Background: Ethnopharmacological relevance: Ruta chalepensis L For years, various portions of this plant have been utilized in traditional medicine to treat a number of illnesses, including nervous disorders, rheumatism, menstrual issues, fever, convulsions, mental disorders, dropsy, and neuralgia. Objection: In this study, we aim to characterize three flavonoids extracted from Ruta chalepensis L.\ Material and Methods: In this study, various concentrations (80\% and 100\%) of methanol and ethanol in water were used as solvents in the extraction of flavonoids (rutin, hesperidin, and quercetin) from Ruta chalepensis L. by using conventional extraction methods (reflex and maceration). Result: HPLC results confirm Using maceration with 80\% methanol was recommended for extracting flavonoids from Ruta chalepensis L. to obtain the highest yields, whereas reflex with 80\% ethanol showed a slight increase in quercetin amount. The phytochemical screening of Ruta chalepensis L. exhibited the presence of flavonoids. Conclusion: The highest amount of the three flavonoids was found in maceration with 80\% methanol.

Background and Objective: Staphylococcus aureus and Methicillin-Resistant Staphylococcus aureus (MRSA) can cause an abscess, a skin condition with a build-up of pus due to a fluid or pus-filled tissue covering. This study aimed to determine the antibacterial activity of the ethanolic extract and its fraction from jawer kotok (Indonesian), Coleus atropurpureus (L) Benth.) against abscess-causing bacteria, S. aureus and MRSA. Materials and Methods: Laboratory Experimental Design. C. atropurpureus was collected, macerated using 96\% ethanol extract, then fractionated using ethyl acetate and n-hexane. Antibacterial properties of ethanol extract and its fraction using S. aureus ATTC 25923 and MRSA. Statistical analysis used: descriptive statistics. Results: It was found that the MIC values for S. aureus ATTC 25923 and MRSA were in the range of 0.78\% - 1.56\% w/v and the MBC value for the two test bacteria was 1.56\% Conclusions: Ethanol extract and n.hexane fraction from C. atropurpureus were new drugs for abscess treatment. It is necessary to research the formulation and evaluation of the ethanolic extract and the n-hexane fraction from C. atropurpureus against the two bacteria that cause abscesses first.

Introduction: Kjellbergiodendron celebicum (Koord.) Merr. (local name: tombe uwa) is a plant endemic to Sulawesi, Indonesia, and grows around lakes or aquatic environments where fish live. Based on phytochemical screening in previous studies, i.e. methanol extract and ethyl acetate fraction from the leaves of Kjellbergiodendron celebicum (Koord.) Merr., the methanol extract gives positive results containing polyphenol compounds in the flavonoid group which have been known to have strong antioxidant and antibacterial properties. Objective: To test the effectiveness of the comparison of the natural content in the compounds (antibacterial and antioxidant properties) and the total content of phenol in Kjellbergiodendron celebicum (Koord.) Merr., which was extracted using two methods, i.e. maceration and Ultrasonic- Assisted Extraction (UAE), in fish-disease bacteria. Method: The leaves were separated to be extracted with two different methods: maceration and Ultrasound-Assisted Extraction (UAE). Extracts were first screened qualitatively for antioxidant activity and then quantified with respect to in vitro antioxidant activity using the 2.2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay and the ferric-reducing antioxidant power (FRAP) assay. Antibacterial activity was determined by the paper disc diffusion method and microdilution. Results: 70\% Ethanol in leaves extract of Kjellbergiodendron celebicum (Koord.) Merr. The extract which has the highest activity based on the DPPH test and FRAP test is the extract from UAE extraction with IC50 value of 9.81512 μg/mL and ferrous equivalent antioxidant capacity (FeEAC) value of 1.661.3 μmol/gr. UAE method also has a higher potential in antibacterial activity based on the diffusion method of paper discs and microdilution with the MIC obtained as much as 390.6 μg/mL. Conclusion: the UAE extraction method is better at scanning polyphenol compounds compared to the conventional maceration extraction method. Therefore, the results of the antioxidant and antibacterial activity using the UAE method are better than the maceration method.

Introduction: Sesewanuwa (Clerodendrum fragrans Wild) is one of the plants with abundant flavonoid content in the leaves. The characteristic flavonoids with the two benzene ring groups cause the process of finding an appropriate extraction technique. Objective: This study aims to determine the total flavonoid levels of ethanol extract of sesewanuwa leaves obtained from maceration extraction methods. Method: This research was carried out by extracting the simplicia of sesewanuwa leaves by maceration method using 96\% ethanol solvent. Comparison between the simplicia and the solvent used is 1:7, then the extract obtained was carried out with initial qualitative identification of flavonoids with simple reagents and the total flavonoid levels were determined using UV-Vis spectrophotometry. Results: The results showed that the ethanol extract of sesewanuwa leaves obtained by maceration extraction method in qualitative and quantitative tests contained flavonoids with quercetin standard with a total content of 13.47\%.This research was carried out by extracting the simplicia of sesewanuwa leaves by maceration method using 96\% ethanol solvent.

Objectives: A free radical is a molecular species characterized by the presence of an unpaired electron in its outer orbital. Free radicals are highly reactive and are known to damage biomolecules including lipids resulting in a myriad of pathophysiological conditions. The present investigation was carried out to screen antiradical and lipid peroxidation inhibitory activity of ripe and unripe fruit of R. steudneri. Methods: The powdered ripe and unripe fruit materials were extracted by maceration process using methanol. Antiradical activity of extracts was evaluated by DPPH and hydroxyl radical scavenging assays. Lipid peroxidation inhibition assay was carried out by estimating the thiobarbituric acid reactive substances. Both ripe and unripe fruit extracts were screened for the presence of phytochemicals viz. alkaloids, flavonoids, tannins, phenolic compounds, saponins, glycosides, sterols and triterpenoids by standard tests. Results: Preliminary phytochemical analysis indicated that both ripe and unripe fruit extracts contain saponins, alkaloids, phenolic compounds, flavonoids, tannins, sterols and triterpenoids. When compared to unripe fruit extract, ripe fruit extract displayed marked scavenging of DPPH and hydroxyl radicals and inhibition of lipid peroxidation as indicated by lower IC50 values. Conclusion: Overall, ripe fruit extract displayed marked free radical scavenging and lipid peroxidation inhibitory activity. The presence of phenolic and flavonoid compounds in the extracts might be responsible for observed bioactivities of ripe and unripe fruit of R. steudneri.
