Pokak plant, also known as takokak or prickly nightshade (Solanum torvum Sw.), belongs to the Solanaceae family. The part of the plant commonly utilized was its leaves. Takokak leaves contained numerous bioactive components that can be developed into one of the functional foods, such as herbal tea. One crucial aspect in the herbal tea-making process is the drying temperature. The aimed of this research was to investigate the effect of drying temperature variations on the characteristics of takokak leaves herbal tea and to determined the optimal temperature that can yield the best characteristics of takokak leaf herbal tea. Parameters observed in this study included total phenols, total flavonoids, total tannins, vitamin C, antioxidant activity, and sensory properties comprising hedonic tests on color, taste, aroma, and overall acceptances. Data obtained were analyzed using analysis of variance (ANOVA), and if there was a significant effect of treatment on the results (P<0.05), it would be followed by the Tukey test. The results showed that variations in drying temperature significantly affected the values of total phenols, tannins, flavonoids, vitamin C, antioxidant activity, and sensory properties regarding color, aroma, taste, and overall acceptances of takokak leaf herbal tea. The best treatment was obtained at a drying temperature of 40°C with total phenol content of 31.58 mg GAE/g, total tannin content of 0.79 mg TAE/g, total flavonoid content of 14.23 mg QE/g, total vitamin C content of 7.92 mg AAE/g, antioxidant activity of 84.26%, and sensory properties for color, aroma, taste, and overall acceptances respectively were 5.73 (like), 5.27 (slightly like), 3.77 (neutral), and 3.91 (neutral).

“…Antioksidan yang berasal dari alam, seperti vitamin C, vitamin E, golongan fenolik, seperti flavonoid, tanin, dan polifenol, dapat mengikat radikal bebas, menghambat stres oksidatif, merangsang pembentukan kolagen, dan mengencangkan kulit, sehingga mencegah penuaan dini (Aizah, 2016;Kusumawulan et al, 2022;Safnowandi, 2022). Aging (penuaan) didefinisikan sebagai proses penurunan fungsi dan kapasitas kulit yang berlangsung progresif (Yusharyahya, 2021).…”

Wedi snakefruit is one of the local species snakefruit produced in Bojonegoro Regency. Antioxidant activity in salak fruit may be influenced by its cultivar. The peel of snakefruit is reported to have antioxidant activity as in salak fruit flesh. Antioxidants can prevent free radical damage to human skin and prevent aging so can be developed in cosmetic preparations. The current trend of antiaging cosmetic preparations leads to preparations with nanoparticle size. The objectives of this study is to determine the antioxidant activity and to characterisation of nanoparticles Wedi snakefruit peel extract that will be developed as anti-aging cosmetics. Wedi snakefruit peel extract was conducted using maceration method with 96% ethanol solvent, antioxidant activity test was conducted by DPPH method and total phenol content determination method using Folin-Ciocalteu method. Nanoparticles preparation of extract by ionic gelation method with characterisation through particle measurement using PSA and zeta potential measurement. Potential antiaging activity was measured through tyrosinase inhibition testing. The results showed the IC50 value measured by DPPH method of 56.10 ppm, total phenolic content of 13.41 mg GAE/g. PSA test results showed particle size of Wedi snakefruit peel extract 884 nm and zeta sizer value of 2 mv. Tyrosine inhibitory activity of Wedi snakefruit peel extract was 63.8%. The antioxidant activity of Wedi snakefruit peel extract is in the strong category, has not met the nanoparticle requirements and has tyrosinase inhibitory activity so that it has the potential to be developed as an antiaging cosmetic.
