“…This study and Singh and Kumar (2015), observed that H. brasiliensis extracts revealed the presence of all phytochemical compounds while saponins were absent. The same type of solvent (ethanol) was used to extract the plant and all the extracts showed negative saponin tests, indicating that H. brasiliensis might contain little or no saponin content.…”

“…According to Singh and Kumar (2015), this study reported that the ethanolic extract of H. brasiliensis did not contain anthraquinones and triterpenoids. The lack of anthraquinones and triterpenoids in certain extracts could be attributed to the unsuitability of ethanol as the extraction solvent for these types of compounds.…”

“…The same type of solvent (ethanol) was used to extract the plant and all the extracts showed negative saponin tests, indicating that H. brasiliensis might contain little or no saponin content. Saponin was examined in the water extraction of H. brasiliensis leaf (Singh and Kumar 2015). Typically, saponins exhibit high polarity, are chemically and thermally unstable, lack volatility, and are commonly present in plants in low concentrations (Li et al 2006).…”

“…In this present study, the leaf extract of H. brasiliensis showed broad-spectrum antibiotic activities. The previous study indicated that H. brasiliensis extract possesses antimicrobial activities against E.coli, K. pneumoniae, and P. aeruginosa (Singh and Kumar 2015). Numerous secondary metabolites from plants and their derivatives have been recognized as potential antimicrobial agents.…”

“…Crude H. brasiliensis leaf extract also has a pharmacological activity that can inhibit the growth of various pathogenic bacteria, namely, Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae. This may be because rubber leaf extract contains important pharmacological substances that inhibit bacterial growth, including flavonoids, polyphenols, tannins, polyacetylenes, terpenoids, sterols, and alkaloids (Singh and Kumar 2015). Serum from latex was effective against Aspergillus niger, but not Candida albicans (Daruliza et al 2011).…”

Belonging to the Euphorbiaceae family, the Para rubber tree is formally referred to as Hevea brasiliensis in scientific terms. It is commonly known as an important economic commodity in Thailand because the natural rubber primarily originates from the milky latex obtained from the tree. However, the available research on the phytochemicals found in different parts of the rubber tree and their biological effects is quite restricted. This study aimed to determine the phytochemical constituents, antioxidant and antibacterial activity studies on the crude dry leaf extracts of H. brasiliensis. The results indicated the presence of alkaloids, anthraquinones, cardiac glycosides, coumarin, flavonoids, saponin, steroids, tannins, and terpenoids. The total phenolic content was 63.95±4.31 mgGAE/g in the ethanolic leaf extract. The ethanolic extract displayed notable effectiveness in scavenging free radicals (71.2±0.17%) at 500 μg/ml concentration and antioxidant capacity (the lowest IC50 value 42.57±0.91 μg/ml). The ethanol extract of the leaf of H. brasiliensis showed inhibition zone on all of the selected bacteria (gram-positive; Bacillus subtilis, Staphylococcus aureus, Staphylococcus epidermidis, and gram-negative; Escherichia coli, Pseudomonas aeruginosa) at 200 mg/ml. In conclusion, the dried leaves of H. brasiliensis compose phytochemicals that exhibit antioxidant and antibacterial activities and possesses the potential to act as a reservoir of plant-derived antibiotics and natural antioxidants.
