A. mearnsii plays an important role in the ecosystem in its native Australia. As a pioneer plant it quickly binds the erosion-prone soil following the bushfires that are common in its Australian habitats. Like other leguminous plants , it fixes the atmospheric nitrogen in the soil. Other woodland species can rapidly use these increased nitrogen levels provided by the nodules of bacteria present in their expansive root systems. Hence they play a critical part in the natural regeneration of Australian bushland after fires.
Carica pubescens Lenne & K. Koch is one of the species in the tropics, which adapt to the plateau environment and low temperatures. In Indonesia, this plant is found at Cangar, Bromo, and Dieng Plateau. This study aims to determine the results of phytochemical screening and total flavonoids in fruit samples were taken from the third place. Qualitative and quantitative tests carried out in the Laboratory of Department of Biology and Chemistry, Faculty of Science and Technology , Maulana Malik Ibrahim State Islamic University, Malang . Analysis of total flavonoids using a spectrophotometer at λ = 510 nm. The results of qualitative phytochemical screening tests on samples of C. pubescens fruits at Cangar, Bromo, and Dieng Plateau shows that the positive sample contains flavonoids, polyphenols, tannins, and triterpenoids. Quantitative test results show that the C. pubescens at Cangar contains total flavonoids quercetin equivalent with value 800 mg / L, Bromo with value mg / L, and Dieng Plateau with value mg / L, respectively.
One of the plants that are used to regular treatment is behind the wind (Mallotus sp.). Traditionally this is used for the relief of pain and increase stamina by way of boiling the seven pieces of young leaves and drink once a day in the morning. This research aims to know the acute toxicity of ethanol extracts of leaves behind the wind (Mallotus sp) against larvae of Artemia salina Leach BSLT method. The research method used is qualitative analysis of chemical compound and Brine Shrimp Lethality Test (BSLT) method with post-test-only control group design. The results of research on ethanol extracts of leaves behind the wind showed the value of LC 50 of ppm, so can be said of ethanol extracts of leaves behind the wind on this experiment of acute toxicity has on the larvae of Artemia salina Brine Shrimp method using Leach Lethality Test (BSLT).
