“…Mengingat pentingnya manfaat senyawa flavonoid dan fenolik sehingga perlu dilakukan penetapan kadar fenolik dan flavonoid total yang terkandung dalam buah parijoto agar penggunaan buah parijoto dapat lebih optimal untuk dimanfaatkan sebagai alternatif obat herbal. Senyawa fenolik dan flavonoid memiliki gugus kromofor yang dapat menyerap radiasi sinar ultraviolet dan sinar tampak sehingga dapat ditentukan kadarnya menggunakan spektrofotometer UV-Vis (Sari et al, 2018).…”

Parijoto (Medinilla speciosa) has a wide range of pharmacological activities due to its secondary metabolite content, especially flavonoid, and phenolic compounds. Flavonoid and phenolic compounds have a major role in human health with their activities as antioxidants, anti-inflammatories, antimicrobials, etc. This study aimed to determine the total levels of phenolic and flavonoid compounds from the ethanol extract of Parijoto fruit. Parijoto fruit is obtained from Bandungan, Semarang Regency, Central Java. Extraction was carried out by maceration method with 70% ethanol solvent then concentrated using a rotary evaporator. The total phenolic and flavonoid content amount was determined using the colorimetric method with Folin-ciocalteau complex reagent on phenolic with gallic acid as the reference standard and AlCl3 complex reagent on flavonoids with quercetin as the reference standard. Absorbance was measured using a UV-Vis spectrophotometer. The results showed that the color of the viscous extract of Parijoto fruit was dark brown with a yield of 6.67% w/w. The total phenolic content of the ethanol extract of Parijoto fruit was 21.67 µgGAE/g extract and the total flavonoid content was 9.21 µg QE/g extract.

Chinese betel can be used to lower cholesterol, heal broken bones, rheumatoid arthritis, anti-fungal medication, gout, protect the digestive system, treat urinary tract disorders and so on. Chinese betel plants contain active compounds such as terpenoids, flavonoids, alkaloids, saponins and phenols. Flavonoids are natural chemicals found in plants. Flavonoids also have antioxidant properties to reduce the effects of free radicals. The research aims to determine the total flavonoid content of Chinese betel extract with variations of 70%, 80% and 96% ethanol using the UV-Vis spectrophotometric method. This method was carried out by quantitative analysis of the total flavonoid content of Chinese betel ethanol extract using UV-Vis spectrophotometry and qualitative analysis using concentrated Mg and HCL powder. The material used is Chinese betel extract (Peperomia pellucida) obtained from Jembrana district, Bali province. Other materials used are 70% ethanol, 80% ethanol, 96% ethanol and ethanol p.a., sodium acetate, distilled water, AlCl3, quercetin, Mg powder and concentrated HCL. The results of testing the total flavonoid content in Chinese betel ethanol extract varied in concentration of 70%, namely containing flavonoids of 2.78576 g/100g EQ, 80% ethanol Chinese betel extract containing flavonoids of 5.132503 g/100g EQ, and Chinese betel ethanol extract 96 % contains flavonoids of 6.77682 g/100g EQ. The highest flavonoid content results were obtained by the 96% ethanol concentration extract because 96% ethanol has polar properties so it can attract flavonoid compounds well. Qualitative analysis of flavonoids showed positive results with the formation of a brownish red color.

Tanaman kerai payung (Filicium decipiens) merupakan salah satu jenis tanaman yang dapat digunakan sebagai bahan alternatif dalam pembuatan obat. Tanaman ini mengandung berbagai senyawa metabolit sekunder seperti senyawa fenolik, flavonoid, tanin, alkaloid, saponin dan terpenoid. Adapun tujuan penelitian ini adalah untuk menentukan kadar total fenolik, total flavonoid ekstrak etanol daun Filicium decipiens serta aktivitasnya terhadap bakteri Propionibacterium acnes dan Staphylococcus epidermis. Ekstrak etanol daun Filicium secipiens diperoleh melalui metode ekstraksi secara maserasi dengan pelarut etanol. Kadar total fenolik dan flavonoid ekstrak etanol daun Filicium decipiens ditentukan dengan menggunakan metode spektrofotometri UV-Visible. Penentuan kadar total fenolik dan flavonoid masing-masing menggunakan pereaksi Folin-Ciocalteau dan . Ekstrak dibuat dalam variasi konsentrasi (25%,50%%,100%) dan dilakukan pengujian aktivitas antibakteri dengan menggunakan metode difusi cakram. Berdasarkan pada hasil penelitian diperoleh bahwa kadar total fenolik dan flavonoid ekstrak etanol daun Kerai Payung masing-masing adalah 234,79 mg/GAE/g dan 4,5905 mg/QE/g. Hasil uji aktivitas antibakteri pada berbagai variasi konsentrasi ekstrak terhadap bakteri Propionibacterium acnes dan Staphylococcus epidermis diperoleh masing-masing zona hambat terbesar pada konsentrasi ekstrak 100% yaitu 17,72 mm untuk Propionibacterium acnes dan 18,18 mm untuk Staphylococcus epidermis. Zona hambat yang dihasilkan tersebut tergolong kuat.
