POTENSI AKTIVITAS TABIR SURYA EKSTRAK DAUN DAN KULIT BATANG DENGEN (Dillenia serrata) SECARA IN VITRO

Abstract

Dengen (Dillenia serrata) is an endemic plant found in Luwu Regency. Its primary utilization is still limited to the fruit as a food ingredient, such as dodol, though leaves and barks are often used as medicine. According to Santi , dengen leaves and bark contain large polyphenols. This study determines the sunscreen activity of the Dengen plant, specifically leaves and bark obtained from Malangke City in Luwu Regency. Also, the study aims to establish the part of the plant with great potential for sunscreen. The leaves and bark of the tree are extracted by maceration using 70% ethanol solvent. The determination of the SPF value was carried out in vitro based on the principle of measuring extraction absorption with a certain concentration at wavelengths of 290-320 nm. The ethanol extract of the bark is made with a concentration series of 100, 200, 300, 400, and 500 ppm, where 100 ppm produced an SPF value of 4,611. Furthermore, the ethanol extracts of the leaves were made in series 50, 100, 150, 200, 250 ppm, where 100 ppm produced an SPF value of 2. This study concluded that the ethanol extract of dengen bark has maximum sunscreen activity with a low concentration compared to ethanol leaves.

Potential Ethanol Exract Kapuk Randu Leaves (Ceiba petandra (L.) Gaertn) as Sunscreen

“…This organic compound is an aromatic group that is conjugated with the para and ortho groups between the electron receiving group and the electron release group, thus allowing for the delocalization and transfer of electrons from the electron-releasing group to the electron receiving group. Mechanical quantum calculations show that the delocalization energy of this electron is related to the radiation energy in the UVA and UV B regions [8]. Based on the results obtained from the test of sunscreen extract ethanol leaves kapuk randu, the concentration value and SPF value are directly proportional.…”

“…Then it measured its absorbance value at wavelengths of 290-320 nm at intervals of 5 nm. The data were analyzed with the Mansur equation as in equation ( 1) to get the SPF value [8]. Based on equation (1) it can be stated that CF is a correction factor, EE is the spectrum of erythema effect, I is the spectrum of solar intensity, and Abs is the absorbance of the sample.…”

“…Based on equation (1) it can be stated that CF is a correction factor, EE is the spectrum of erythema effect, I is the spectrum of solar intensity, and Abs is the absorbance of the sample. Meanwhile, the value of EE x I is constant, where the value has been set by Sayre in Dutra [8] as shown in Table 1 below.…”

“…Secondary metabolite compounds such as flavonoids and polyphenols have good potential as sunscreen agents. This is because these secondary metabolite compounds have aromatic groups conjugated with carbonyl groups where these compounds can stabilize electron displacement because they can absorb or reduce the intensity of UV radiation [8] [9]. One of the natural ingredients that can be used as sunscreen is kapuk randu leaf (Ceiba petandra (L.) Gaertn) because it contains polyphenols and flavonoid compounds [10].…”

Extraction of The Chemical Components of Dengen Leaves (Dillenia serrata Thunb) by MAE Method and Activity Test as Antioxidant and Toxicity

“…Dengen plant is used in traditional medicine. Dengen bark decoction is used as a medicine for vomiting blood Windardi et al, 2006;Sinala et al, 2021. Dengen leaf decoction is used as a remedy for indigestion. Dengen fruit juice is used as a thrush medicine (Purnawati et al, 2020).…”
