Abstract

Piperonal as a precursor of cancer drug (Curcumin analogues) can be synthesized from extract of lawang’s bark (Cinnamomum culilawan Blume) with multiple stages, among others: isolation of essential oils, isolation safrole, safrole isomerization, and synthesis of piperonal. Essential oils were isolated from the bark of lawang (the water content of 46.2%) using a water distillation system with 1/3 volume of high boiler for five hours. Isolation of safrole from lawang bark oils was performed using NaOH solution and purified using reduced pressure distillation system at a temperature of 90-123°C / 1 mmHg. The safrole isomerization was undergone using alkali catalyst (KOH) without solvent at a temperature of 120°C for 8 hours. Oxidation of isosafrol was performed using KMnO in acidic conditions using a KTF 4 tween 80 at a temperature below 30°C, and purified using silica gel. Results of isolation yield 0.94% with 14 components were determined through GC-MS, including 67.35% eugenol, safrole 13.96%, 12.61% methyl eugenol, 4-terpineol sineol 1.79% and 1.55%. The isolated safrole yield of 17.21% with purity testing and identification using FTIR, HNMR and GCMS confirmed the product was safrole. The isomerization obtained yield of 77.56% with GC analysis indicated compounds of cis-isosafrole and trans-isosafrole. The results of oxidation obtained yield of 65.63% with a purity of 100% by GCMS and the H-NMR indicated the product is piperonal.

Abstract

 Increasing antibiotic resistance has prompted the search for safer and more sustainable natural alternatives. Ipomoea pes-caprae, a coastal plant traditionally used for the treatment of wounds and inflammation, is known to be rich in secondary metabolites such as flavonoids, terpenoids, alkaloids, and phenolic acids that have potential antioxidant and antibacterial properties. This study aimed to map the metabolite profile of the methanolic extract of I. pes-caprae leaves using LC-HRMS, to analyze its relationship with antioxidant activity measured by the DPPH method, and to evaluate its antibacterial activity against Staphylococcus aureus and Escherichia coli. LC-HRMS analysis identified 406 compounds with Palmitic Acid as the dominant component (24.503%), including primary and secondary metabolite groups such as flavonoids (quercetin, rutin, kaempferol), phenolic acids (caffeic, ferulic, chlorogenic acid), terpenoids (caryophyllene oxide, lupeol), alkaloids, and phytohormones. The methanol extract showed moderate antioxidant activity (IC₅₀ = 136.71 ppm) and antibacterial activity against E. coli (inhibition zone 9.5 mm), which is thought to originate from the synergy of various secondary metabolites through free radical scavenging mechanisms and bacterial membrane damage. These findings strengthen the scientific basis for I. pes-caprae as a natural source of antioxidant and antibacterial agents for the development of natural pharmaceutical products.
