Abstract

Aging is a natural skin process that occurs due to intrinsic and extrinsic factors, such as excessive exposure to ultraviolet light (photoaging). The mechanism of damage involves the production of excess free radicals that trigger oxidative stress in the skin. Determining the natural products that have high antioxidant activities as antiaging is up most important. Cinnamomum burmannii and Michelia champaca are typical Aceh plants that are believed to have high antioxidant effects. The aim of this study was to determining the contents of C. burmannii and M. champaca as well as to determine the antioxidant and antiaging activities of either individually or combinations. The qualitative phytochemical and semi-quantitative analysis of the extracts were conducted using gas chromatography and mass spectroscopy (GC-MS). The antioxidant activity was examined by radical scavenging using the DPPH radical while the antiaging activity was tested the tyrosinase enzyme inhibition test. The phenolic and flavonoid contents of C. burmannii were higher than M. champaca (66.34 vs 24.71 mg gallic acid equivalent/gr) and (80.52 vs 60.20 mg quercetin equivalent/gr). The inhibitory concentration (IC₅₀) of M. champaca extract in inhibiting DPPH indicated that M. champaca had a better antioxidant activity than C. burmannii. The combination of C. burmannii and M. champaca extracts had a lower IC₅₀ compared to M. champaca alone. C. burmannii and M. champaca extract had a weak potential to inhibit tyrosinase activity (IC₅₀ value ≥1000 µg/mL). In conclusion, this study indicates that M. champaca and C. burmannii have strong antioxidant activities and these might associate with polyphenol contents.

Abstract

Second-degree burn, the most common among burn degrees, underscores the importance of timely and proper treatment in influencing prognosis. Nutmeg (Myristica fragrans), renowned for its potent antibacterial and antifungal properties, also serves as an effective antiseptic for open wounds. The aim of this study was to identify the phytochemical constituents of nutmeg essential oil and analyze the wound healing effect of nutmeg cream on second-degree burns in an animal model. An experimental study with a completed randomized design was conducted on Rattus norvegicus strain Wistar rats with second-degree burn. This study had four groups and each group consisting of four rats: B (burn-treated base cream), B+N (burn-treated 3% nutmeg cream), B+SSD (burn-treated silver sulfadiazine (BSS)), and B+N+SSD (burn-treated 3% nutmeg cream and SSD in a 1:1 ratio). The phytochemical analysis of nutmeg essential oil was conducted by gas chromatography and mass spectroscopy (GC-MS). The burn diameter and burn wound healing percentage were measured from day 0 to 18. One-way ANOVA followed by post hoc analysis using the least significant difference (LSD) was employed to analysis the effect. The phytochemical analysis of nutmeg essential oil found that myristicin, terpinene-4-ol, terpinene, safrole and terpinolene were the most abundant putative compounds in nutmeg essential oil. On day 0, the average burn wound diameters were 1.4 cm in all groups and increases were observed in all groups in day 3. The wound diameter decreased until day 18 with the smallest burn wound diameter was found in the B+N group (0.86±0.37 cm), followed by B+SSD (0.93±0.29 cm). The B+SSD group exhibited the highest percentage of burn wound healing (56.80±14.05%), which was significantly different from the base cream (p<0.05). The percentage of burn wound healing in rats given 3% nutmeg cream was 41.88±13.81% suggesting that nutmeg cream could promote burn wound healing in rats induced by second-degree burns.
