“…Pengujian kualitatif dilakukan dengan me-nambahkan ekstrak kental sebanyak 50 mg dilarutkan ke dalam 5 ml etanol 95 % lalu diuapkan hingga kering, ditambahkan 0,1 g serbuk magnesium, 10 tetes asam klorida pekat. Warna merah jingga hingga merah ungu yang terbentuk menunjukan positif adanya flavonoid, jika terjadi warna kuning jingga menunjukan adanya flavon, kalkon dan auron (Azizah & Wati, 2018;Malik et al, 2016). Pengujian kandungan flavonoid menggunakan baku pembanding kuersetin dengan reagen AlCl3 10 % (Zou et al, 2004).…”

Staphylococcus epidermidis merupakan bakteri flora normal kulit. Ketidaknormalan flora normal akan menyebabkan gangguan kulit diantaranya jerawat. Pengembangan kosmesetika sebagai antibakteri perlu terus dilakukan salah satunya menggunakan bahan alam daun beluntas. Beluntas merupakan tanaman yang memiliki aktivitas sebagai antibakteri dan anti inflamasi karena mengandung metabolit sekunder seperti tannin, polifenol, flavonoid dan minyak atsiri. Ekstrak dilakukan purifikasi untuk memperkecil massa ekstrak. Tujuan penelitian dilakukan untuk mengevaluasi ekstrak terpurifikasi daun beluntas dalam formulasi krim sebagai kandidat kosmesetika yang dapat menghambat pertumbahan bakteri S. epidermidis. Sediaan krim dilakukan pengamatan karakteristik fisik untuk melihat stabilitas krim dalam penyimpanan. Sediaan krim dilakukan uji antibakteri terhadap S. epidermidis menggunakan metode difusi. Krim yang mengandung ekstrak daun beluntas 5% b/v, 10% b/v dan 15% b/v memiliki aktivitas antibakteri terhadap S. epidermidis dengan diameter zona hambat berturut – turut sebesar 9,9±0,022 mm (sedang), 14,9±0,019 mm (kuat), dan 20,9±0,049 mm (sangat kuat). Krim daun beluntas tidak mengalami perubahan pada pengujian organoleptis. Pengujian nilai pH dan viskositas mengalami peningkatan tetapi masih memenuhi kriteria sediaan krim.

Renggak (Amomum dealbatum Roxb.) is a species from the genus Amomum widely spread in Lombok. Traditionally, Amomum dealbatum Roxb. (renggak) is an antiseptic to treat rheumatism and arthritis. However, there was limited report of its phytochemical contents and biological activity of Amomum dealbatum Roxb. This study is preliminary research that aims to determine the phytochemical content of Amomum dealbatum Roxb. leaf decoction and its ethanolic extract. For this study, we used two different extraction methods. The fully powdered plant used for the successive extraction in the cold process for maceration methods was 800 g, and ethanols were used as solvents. We used a traditional receipt that utilized three fresh leaves in the decoction methods with 4,5 L of water as solvents. Phytochemical screening was carried out qualitatively by using the tube method with specific reagents for each compound. Important phytochemicals that were screened are flavonoids, alkaloids, tannins, saponins, steroids, and triterpenoids. Phytochemical screening from plant extract and decoction revealed the presence of flavonoids, alkaloids, and tannins. Triterpenoid was only detected on the extract, and none of the extract and decoction have saponins and steroids. Our finding provides information about secondary metabolites that present in Amomum dealbatum Roxb. These phytochemical findings are essential and might be useful as quality parameters and to predicts its biological activities.

AKTIVITAS ANTIBAKTERI AIR PERASAN DAN REBUSAN DAUN CALINCING (Oxalis corniculata L.) TERHADAP Streptococcus mutans

Inappropriate use of antibiotics can cause bacteria to become resistant and have side effects, therefore an alternative source of antibacterial is needed. One species of plant that has antibacterial properties is calincing (Oxalis corniculata L.). Antibacterial activities of the juice and decoction of calincing leaves against Streptococcus mutans have not reported yet. This study aims to determine the antibacterial activity of the juice and decoction of calincing leaves against Streptococcus mutans. This study uses a well diffusion method with eight treatment groups, namely juice and decoction at the concentrations of 20%, 40%, 60%; listerin 100% as a positive control, and distilled water as a negative control. The diameter of the inhibitory zone of the juice and decoction of calincing leaf at a concentration of 20% are 19 mm and 24.33 mm respectively, and classified as strong growth inhibition, while the concentrations of 40% and 60% are classified as very strong growth inhibition. Growth inhibition of the juice and decoction of calincing leaf at concentration of 20% was significantly higher than the positive control. The best antibacterial activity against Streptococcus mutans is produced by the juice and decoction of calincing leaf at concentration of 60%. Increasing in the concentration of the juice or decoction of calincing leaf also increases the diameter of the inhibitory zone.
