Acalypha Indica

Many local plants in Indonesia were used as traditional medicines, such as sunflower (Helianthus annuus) and anting-anting (Acalypha indica Linn) plants. Both of them can be used as an antimalarial, antibacterial, antifungal, analgesic, and antihyperlipidemic. This study aims to provide an overview of the secondary metabolites groups contained in sunflower leaf and anting-anting plants for the testing of alkaloids, flavonoids, tannins, saponins, steroids/triterpenoids, and sesquiterpenoids. This study included the extraction of sunflower leaves and anting-anting plants separately using the maceration method for 24 hours with 80% ethanol solvent. The stirring was aided by a shaker for three hours. Each extract was tested by phytochemicals with reagents. The results of phytochemical tests with reagents showed that 80% ethanol extract of sunflower leaves contained an alkaloid, tannin, steroid, and sesquiterpenoid compounds whereas anting-anting plants contained an alkaloid, flavonoid, and triterpenoid compounds.

Acalypha Indica

Acalypha indica Linn is a tropical weed, grows annually in East Nusa Tenggara. The weed is member of Euphorbiaceae family, a largest plant family known as medicinal plant. The weed leaves were used by local people in NTT to treat wounds, diseases or myasis on their livestock. This study aim to investigate the secondary metabolites in A. indica L leaves as a scientific proven for its local use.  The extract preparation comprises of several steps, i.e collection of fresh leaves, dry and wet sortation. The clean leaves were air dried in a room temperature for about 2 weeks before grounded into powder and subjected to extraction. The extraction method was maceration with ethanol 96% as solvent. The dense extract was evaporated using rotary evaporator and subjected to phytochemical screening. The result shows that ethanol extract of A.indica leaves were tested positive for flavonoid and tannin. Alkaloid, saponins, triterpenes and steroid were tested negative on the extract.

Bundung plants (Actinuscirpus Grossus) are widely spread in Borneo and used by society empirically as antimicrobials. Nevertheless, the use of Bundung plants as traditional medicine has not been equipped with convincing data, because there is no research that is related to the plants. In order to the use of the plants accountable, it is necessary to conduct research about phytochemical screening studies and tests the antimicrobial activity of ethanol extract of Bundung plants to staphylococcus aureusandEschericia Coli bacteria. Moreover, extraction does with maceration method. Secondary metabolite groups which are contained in the ethanol extract of Bundung plants were determined qualitatively using several of phytochemical reagents. The result of phytochemical screening test showed that ethanol extract of Bundung plants contains a group of secondary metabolites; namely flavonoid, tannin, saponin, phenolic, steroid and terpenoid. The method that was used to test antimicrobial activity to Staphylococcus aureusandEschericia Coli bacteria was a liquid dilution method with variations in extract concentration of 0,5%, 1%, 2%, 4% and 8% by considering at the clarity of each sample. The result of antimicrobial activity of liquid dilution to bacteria had inhibition at all concentrations and the biggest inhibitory activity was shown at concentration 8% with the clearest level and the MIC grade of the test is at a concentration of 1%. Based on the findings, it can be concluded that ethanol extract of Bundung plants has the potential of activities of an antimicrobial, especially from secondary flavonoid metabolites.

Free radicals are one form of reactive oxygen compounds, which are generally known as compounds that have unpaired electrons. Kemangi leaves are used as an aphrodisiac because they contain araginin which can strengthen sperm resistance and prevent infertility. Besides araginin, Kemangi leaves also contain other secondary metabolites such as essential oils, phytosterols, alkaloids, phenolic compounds, tannins, lignin, saponins, flavonoids, terpenoids and anthraquinones. Phytochemical screening results of 70% ethanol extract of kemangi herbs themselves showed the presence of secondary metabolites of flavonoids, saponins, tannins and triterpenoids / steroids. In this study, antioxidant activity was tested using the FRAP (Ferric Reducing Antioxidant Power) method, with concentrations of kemangi leaf extract and comparative compounds Euginol each concentration of 1000 μL/ml, 5000 μL/ml, 250 μL/ml, and 125 μL/ml, 62.50 μL/ml, and 31.25 μL/ml measured at 745 nm wavelength and collagenase inhibition test with ethanol extract of kemangi leaves with a comparison of eugenol compounds measured at a wavelength of 335 nm. The FRAP antioxidant activity results obtained based on IC50 Eugenol value of 261.36 μg/ml and Kemangi leaf extract at 111.32 μg/ml, antolagenagenase from Eugenol at 255.32 μg/ml and Kemangi leaf extract at 110.65 μ/ml.

Abstract Aquilaria beccariana van Tiegh is one of the agarwood (gaharu) species that grows naturally and cultivatived. However, the chemical and antioxidant potential of its leaves have not been studied much. This research aimed to examine the chemical compounds and the antioxidant activity of the ethanol extract of the agarwood leaves A. beccariana van Tiegh which grows naturally and cultivatived. The leaves were processed into simplicia and then extracted using 96% ethanol as solvent. Phytochemical screening agarwood leaves to determine the chemical compounds such as of alkaloids, flavonoids, glycosides, steroids/triterpenoids, saponins and tannis. The antioxidant activity test was carried out using the DPPH method to obtain the IC50 (Inhibitory Concentration) value. The compound tracing used GC-MS. The results showed that the simplicia and the extract of the leaves both natural-grown and cultivated contained secondary metabolites of alkaloids, flavonoids, steroids/triterpenoids, and tannins positively, whereas the glycosides were only found in cultivated type. The result of the antioxidant activity test showed that the ethanol extract of the leaves of A. beccariana van Tiegh both natural-grown and cultivated was categorized as very strong. The results of the identification of chemical compounds by GC-MS were identified 18 compounds in the natural-grown leaves, while 40 compounds were identified in the cultivated ones.

The purpose of this study was to determine the IC50 value and antioxidant potential of the ethanol extract of mangga kasturi leaves (Mangifera casturi Kosterm.). The ethanol extract of mangga kasturi leaves (Mangifera casturi Kosterm.) was extracted using maceration with 96% ethanol as solvent. The antioxidant activity test was carried out using the DPPH (1,1-Diphenyl-2-Picrylhydrazil) method using a UV-Vis spectrophotometer and vitamin C as a comparison. The results of phytochemical screening tests on ethanol extracts showed positive secondary metabolites such as alkaloids, flavonoids, tannins, and quinones.
