Study Findings
• Antibacterial: Study of S jambos leaf extract showed inhibition of gram-positive and gram-negative bacteria, the latter more susceptible than the former.
• Antinociceptive: Study showed Syzygium jambos extract has remarkable analgesic effects on both cutaneous and deep muscle pain not mediated by opioid receptors in an efficacy higher than that shown by diclofenac.
• Antimicrobial / Tannins: Study showSJ extracts showed antibacterial activity against S aureus, Y enterocolitica, Coagulase-negative staph. The activity seemed related to the high tannin content.
• Antidermatophytic / Triterpenoids:Study yielded known triterpenoids – friedelin, ß-amyrin acetate, betulinic acid and lupeol. Results showed antidermatophytic activity against three species: Microsporum audounii, Tricophyton soudanense and T mentagrophytes.
• Radical Scavenging / Dihydrochalcones: Study of leave extracts yielded three dihydrochalcones – phloretin 4′-O-methylester(2’6′-dihydroxy-4-methoxydihydrochalcone, myrigalone G and myrigalone B which showed radical scavenging properties towards the DPPH assay.
• Hypotensive: Study of aqueous fraction of the young boiled leaves extract of Syzygium jambos, treated with ethyl acetate, has an important hypotensive effect.
• Antimicrobial: Study evaluated the antimicrobial efficacy of S. jambos against 8 different microorganisms, viz., S aureus, B subtilis, E Coli, K pneumonia, P vulgaris, P aeruginosa, S typhi and V cholera. Different extracts showed varying degrees of inhibitory activity. Overall the acetone extract was found to be more effective.
• Antioxidant / Hepatoprotective / Leaves: Study evaluated the leaves of Syzgium jambos for antioxidant activity in vitro and hepatoprotective activity in vivo. The extract showed significant dose-dependent antioxidant activity and hepatoprotective activity in CCl4-induced liver damage.
• Aroma Compounds / Fruit: Study evaluated the rose apple fruit for aroma compounds. Results yielded medium and high volatility components. Hexanal, 3-penten-2-one, hexanol, (Z)-3-hexen-1-ol, linalool, isovaleric acid, benzyl alcohol, 2-phenylethylalcohol and (E)-cinnamaldehyde were potent odorants contributing to the headspace aroma.
• Antibacterial / Anti-Inflammatory / Acne Vulgaris: Acne is considered a chronic skin disorder resulting from the production of reactive oxygen species due to involvement of Propionibacterium acnes in the skin. Study showed S. jambos possesses antibacterial, antioxidant, and anti-inflammatory effects warranting clinical studies for use as possible alternative anti-acne agent.
• Leaf Essential Oils / Anti-Inflammatory / Acne Vulgaris: Study showed the main factor that influenced the chemical composition of leaf essential oil was the collection period. Results also suggest composition was influenced mainly by foliar nutrients (N, Mn, Co, Fe, S, and Mg) and soil nutrients (Na, Al, S, and H+Al).
• Antioxidant / Ripe and Unripe Fruits: Study showed the rose apple pulp extract in ripe state has lower antioxidant and free radical scavenging activity than that found in unripe state. However, both show benefit as natural antioxidants.
