The dichloromethane extracts were separated into neutral and acidic fractions and then analyzed using GC-MS. The neutral fraction analysis revealed that spathulenol, caryophyllene oxide, aromadendrene oxide, and isoaromadendrene epoxide were the major constituents in all three species. Furthermore, the main compound in the neutral fraction of Shorea hopeifolia was isocaryophyllene which was undetected in the other two species. The major constituent of the acidic fraction of the three species was hexadecanoic acid, while pentadecanoic acid was the major constituent in the acidic fraction of Shorea pinanga and Shorea hopeifolia. Therefore, the presence of sesquiterpenes as well as fatty acids in S. macrophylla, S. pinanga, and S. hopeifolia was discovered to be a marker for identifying the genus Shorea.

The cheapest coolant is water, which in the long run can corrode the radiator. To prevent corrosion requires an eco-friendly corrosion inhibitor. One of the corrosion inhibitors found in coastal areas is mangrove (Rhizophora mucronata) leaves. The research aimed to make Mangrove leaves extract as a corrosion inhibitor on steel or iron alloy, identify chemical content of Mangrove leaves extract, and calculating the effect in corrosion rate. 10 kg of dry mangrove leaves, dissolved in 10 liters of 96% ethanol and concentrated into 200 ml. Electrochemical testing using distilled water as media and added with mangrove extracts concentrations were 0, 5, 10, 15, and 20%. A potentiostat/ galvanostat (PGSTAT101) was used to obtain anodic and cathode polarization curves for steel with different concentrations of Mangrove extract. Based on emission spectroscopy, steel or iron alloy contained Fe, Mn, C, Si, and Ni. Based on the GC-MS test result, there are 5 major chemical components of mangrove leaves extracts, i.e., 2-O-methyl hexose, Catechol, 3-O-methyl-d-glucose, Cyclopentyl 4-ethyl benzoate, and 4-O-methyl mannose. Increasing mangroveleaves extracts concentration as steel or iron alloy corrosion inhibitor changes the Tafel diagram downward. Mangroveleaves extracts in water showed corrosion inhibitor of steel or iron alloy efficiency up to 27% at a concentration of 20%.
