“…According to research by Andarwulan et al (2010), the flavonoid component in purslane ethanol extract has antioxidant activity [18]. According to Lolo et al (2017), the phenolic components of purslane have antioxidant activity [19]. Lim et al (2014) investigated the antioxidant activity of the entire purslane plant [20].…”

BACKGROUND: Purslane (Portulaca oleracea L.) is a wild plant that grows in Indonesia and is considered a weed, but it has the highest antioxidant activity in the leaves and stems. Cigarette smoke is one of the exogenous free radicals that can enter blood circulation, interfering with all cells and tissues in the body, including reproductive organs. AIM: The research aims to examine the antioxidant effect of purslane leaf extract on oxidative stress levels (ovarian malondialdehyde [MDA] levels) and reproductive hormone levels (follicle-stimulating hormone [FSH] and 17ß-estradiol) in female white rats exposed to cigarette smoke. METHODS: This study is an experimental study with randomized post only control group design, using 12-week-old female Wistar strain Rattus norvegicus weighing about 200–250 g divided into four treatment groups (n = 6). Negative control without exposure to cigarette smoke and purslane leaf extract (K), cigarette group with cigarette smoke 1 stick/day administration without purslane leaf extract (P1), purslane group with purslane leaf extract 200 mg/Kg BW without exposure to cigarette smoke (P2), and group the group with cigarette smoke 1 stick/day accompanied by purslane leaf extract 200 mg/Kg BW administration (P3). Ovarian MDA measurement measures MDA levels as an indicator of oxidative stress in the ovaries determined by the spectrophotometry method. The enzyme-linked immunosorbent assay method measured the measurement of FSH and 17ß-estradiol levels in blood taken intracardially through the right ventricle of the heart. RESULTS: The results showed that purslane leaf extract at a 200 mg/Kg BW dose reduced ovarian MDA levels of female white rats exposed to cigarette smoke significantly with p < 0.05. CONCLUSION: However, there has been no significant change in FSH and 17ß-estradiol.

“…Jika dibandingkan dengan beberapa tanaman lain, seperti pada propolis dimana pada konsentrasi 400 ppmbaru memiliki proteksi minimal dengan SPF 3 , untuk ekstrak etanol herba krokot memiliki SPF 19,495 (Lolo, Sudewi and Edy, 2017) dan pada ekstrak etanol kulit batang bangkal memiliki kemampuan sebagai tabir surya yaitu pada konsentrasi 250 ppm memiliki nilai SPF 10 (Rahmawanty, Maulina and Fadhilaturrahmah, 2017).…”

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.

“…Penelitian tentang aktivitas antioksidan dari tanaman krokot secara utuh telah banyak dilakukan (Lim et al 2014;Andarwulan et al 2010;Lolo et al 2017), tetapi belum ada yang mengamati perbedaan aktivitas antioksidan dan kandungan senyawa fenolik dan flavonoid pada tiap organ tanaman krokot. Hal ini mendorong studi lanjutan untuk mencari bagian organ tanaman krokot yang paling berpotensi sebagai antioksidan.…”

Antioxidant are needed to prevent free radical inside the body and oxidative stress that promotes the aging process and various degenerative diseases. Portulaca grandiflora Hook. is known to have potential as antioxidant. Differences in plant parts can cause differences in phytochemical content, which can affect its antioxidant activity. This study aims to measure total phenolic and flavonoid content in leaf, old stem, young stem, and flower organs of purslane plant (Portulaca grandiflora Hook.) which is extracted using ethanol 96% and determined the antioxidant activity of the extract with DPPH methode. The result showed that each plant organ of purslane contains different concentration of phenolic and flavonoid compounds. The highest total phenolic and flavonoid content was found in the leaves( 113.26 ± 3.85 mg GAE/g and 97.99 ± 1.28 mg QE/g), but the highest antioxidant activity was found in the old stem with IC50 value 122.15 ± 1.30 ppm (classified as medium antioxidant). Keywords: Antioxidant, Flavonoid, Phenolic, Portulaca grandiflora Hook.
