Cestrum nocturnum with white flowers has potential as a medicine, so it is possible that yellow, red and purple flowering plants also have bioactivity. Toxicity tests on plants can increase research on new sources of ingredients for food additives, drugs, pesticides, etc., so as to find the prospective economic value of these plants and maintain plant biodiversity. The aims of this research were to determine the differences in the toxicity of terpasan leaves (Cestrum elegans) of yellow, red and purple flowers. Steps of this research were made the simplicial of terpasan leaves, phytochemical screening, and toxicity test using the Brine Shrimp Lethality Test (BSLT) method. The yield of ethanol extract terpasan leaves with yellow, red and purple was 16.58%, 22.06% and 22.14%, respectively. The results of phytochemicals screening of three types terpasan leaves using the third tube method attached contain secondary metabolites of alkaloids and terpenoids. Based on the toxicity test with the BSLT method using a variation of 150; 200; 250; 300 and 350 ppm mortality percentages were 0.77%, 5.71%, 8.64%, 22.38% and 42.3%. The C50 of the red-pressed ethanol extract was 458.00 ppm, the LC50 of the purple-pressed ethanol extract was 180.127 ppm, the LC50 of the yellow-pressed ethanol extract is 30 – 200 ppm. Conclusion:Based on the LC50 value, the ethanolic extract of the yellow and red leaves has activity as a pesticide, because it has an LC50 value of 200 -1000ppm. The ethanolic extract of purple terpasan leaves has antimicrobial activity because it has an LC50 value of 30-200 ppm

Tarap (Artocarpus odoratissimus Blanco) is one of the plants in the tropics that are consumed by dayak tribe in East Kalimantan. Toxicity tests on seeds and bark have been done but there is no data regarding the acute toxicity of Artocarpus odoratissimus Blanco seeds and flesh of fruit causing the need for acute toxicity tests. This Research to know the acute toxic effects of tarap (Artocarpus odoratissimus Blanco) seed and flesh extracts on larvae of Daphnia magna. Tarap seeds and flesh (Artocarpus odoratissimus Blanco) was taken from dayak market in Samarinda, is East Kalimantan, Indonesia. The seeds and flesh of the tarap fruit are extracted by maceration with ethanol solvent. An acute toxicity test was performed by exposing Dapnia magna larvae aged ≤ 24 hours with a solution of the experimental group and the control group for 48 hours. Toxicity test results are expressed in percentage of immobilization of larvae of Daphnia magna calculated by probit test to obtain EC50 (Half maximal effective concentration) values. Extracts are toxic if the EC50 value > 1000ppm. EC50 Ethanol extract of tarap seeds obtained values ( 3922,301 ± 324,590 ) for EC50 24h and ( 2964,498 ± 412,498 ) for EC50 48h. The EC50 value of ethanol extract from flesh of tarap fruit is ( 12224.514 ± 2186. 899 ) EC50 24h and ( 6165,235 ± 1940,006 ) EC50 48h.Ethanol extract of tarap fruit and flesh is non toxic to larvae of Daphnia magna.

Free radicals and reactive species are widely believed to contribute to the development of several diseases by causing oxidative stress and eventually oxidative. Vernonia amygdalina (Astereacea) is a small shrub or tree between 1 and 5m high growing throughout tropical Africa. Plants are generally known as bitter leaves is well cultivated and is a general market for merchandise in several countries. The purpose of this study was to determine the antioxidant activity of hexane fraction from ethanol extract od Frican leaves (Vernonia amygdalina Del.). The method used in this study was the DPPH (1,1-Diphenil-2-Picrylhydrazyl) method. The result of phytochemical screening showed that ethanolic extract of African leaves contained a composition of secondary metabolites of alkaloids, flavonoids, tannins, steroids/triterpenoids and saponins. The antioxidant activity of the extract of n-hexane fraction was classified as very weak with an IC50 value of 317.98 ppm.

This study was started by extraction of Eucalyptus deglupta Blume. Using organic solvent   (n-hexane, ethyl acetate, ethanol and water) followed by phytochemical screening and toxicity test using Brine Shrimp Lethality Test (BSLT) method. Isolation and identification of chemical compounds contained in the fraction were done by column chromatography and Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Phytochemical screening revealed the presence of alkaloids, flavonoids, steroids and phenolics in the extract. Toxicity test results showed that the ethyl acetate extract was potentially active with LC50 value of  617.95 ppm. The extract was continued to isolation stage and gave fraction EKEA-3.1 with LC50 value of 2759.93 ppm. Identification of chemical compounds in EKEA-3.1 with KG-MS analysis showed that EKEA-3.1 was suspected to be Stigmastan-3,5-diene.

Objective: To evaluate antianxiety effect of dried fruits of Prunus americana Marsh. Family Rosaceae.Methods: Phytochemical screening was performed on various extracts of the fruits. Elevated plus maze and light/dark choice tests were used for screening of antianxiety activity. Diazepam (2 mg/kg) was used as the standard drug.Results: Phytochemical screening has shown the presence of various constituents such as flavonoids, carbohydrates, tannins, alkaloids, phenols, and saponins. Different concentrations (100 and 200 mg/kg) of the ethanolic extract of P. americana have shown promising results. Significant antianxiety activity was observed in ethanol extract at the dose of 200 mg/kg in both models.Conclusion: The present study suggests that ethanolic extract of P. americana contains certain chemical components that are responsible for the antianxiety effect of the fruits of the plant. The plant may be considered for the management of various disorders related to anxiety.

Macaranga bancana (Euphorbiaceae) known as “mahang” which is wide spread in Indragiri Hulu, Riau Province and also believed to has medicinal properties. This study to evaluate the secondary metabolites contents and toxicity activity from various extracts of M. bancana leaves. Extraction process were done by using maceration method with various solvents, such as n-hexane, dichloromethane, ethyl acetate, methanol, and ethanol. Toxicity analysis was done by Brine Shrimp Lethality Test (BSLT). The results of phytochemical screening showed that M. bancana leaves contain terpenoid, steroid, flavonoid and phenolic. Toxicity analysis showed that n-hexane extracts prossessed the highest level of toxicity followed by dichloromethane, ethyl acetate and methanol extracts with LC50 value of 65; 87; 227; 605 μg/mL, respectively while ethanol extract has not toxic. Therefore, it could be concluded that M. bancana has good toxicity level and could be used as screening for anticancer.

The aim of present study was to investigate the preliminary phytochemical, physicochemical, TLC, minerals analysis and In-vitro antioxidant activity of leaves of ethanolic extract of Heldigardia populifolia. The preliminary phytochemical screening of ethanolic extract showed the presence of triterpenoids, flavonoids, glycosides, sterols, steroids, phenols, carbohydrates and saponins. The composition of minerals found in the leaf powder was within the permissible limits. TLC analysis of ethanol extract showed the five spots which indicate the presence of five phytoconstituents. The extractive value of ethanol was high than acetone. Ash values were within the limits. The in-vitro antioxidant activity of ethanolic extract increased with increasing the concentration. The ethanolic extract in all the concentration showed the significant antioxidant activity.

Bauhinia variegata is a plant that has many virtues and widely grown in Indonesia. Yet the virtues and uses are still limited as the shade and ornamental plant. The purpose of this study is to determine the antibacterial ethanol extract activity and the infuse of Bauhinia Variegata leaves toward Streptococcus pyogenes and to determine the classes of compounds that have antibacterial activity. Bauhinia variegata leaves are extracted by maceration and infundation with 96% ethanol and distilled water. The test method of antibacterial activity is used disc difusson Kirby Bauer methods. The Analyses of the compounds which are contained in the Bauhinia Variegata leaves are done by TLC (Thin Layer Chromatography) and test tubes. The results showed that ethanol extract and infuse of Bauhinia Variegata leaves has no antibacterial activity toward Streptococcus pyogenes. TLC results and test tubes showed that the ethanol extract of Bauhinia Variegata leaves contain tannins, saponins, terpenoids, and alkaloids. While, the infuse of Bauhinia variegata leaves are saponins and alkaloids. Keywords: Bauhinia variegata, antibacterial, Streptococcus pyogenes, maceration, infundation.
