Abstract

Labu kuning merupakan salah satu tanaman yang dimanfaatkan buahnya dan mempunyai daya antioksidan yang kuat serta  mengandung karotenoid yang kaya akan vitamin larut air, fenolat, flavonoid polisakarida, garam mineral, dan vitamin. Standarisasi ekstrak dilakukan untuk menjamin mutu dari suatu bahan baku obat tradisional termasuk ekstrak untuk dijadikan sediaan yang juga akan berpengaruh terhadap kualitas sediaan maupun efek terapinya. Standarisasi ekstrak etanol labu kuning dilakukan dengan parameter spesifik yang meliputi uji organoleptis degan melihat berdasarkan panca indera (bentuk, bau, warna, dan rasa), uji kualitatif fenol berdasarkan pereaksi warna, uji semi kuantitatif fenol dengan metode KLT (Kromatografi Lapis Tipis), dan uji kuantitatif fenol dengan menggunakan pereaksi Folin-Ciocalteau dan larutan standar asam galat. Parameter non spesifik yang dilakukan adalah pemeriksaan pH ekstrak dengan menggunkan pH meter, bobot jenis ekstrak, dan cemaran mikroba dengan menghitung Angka Lempeng Total (ALT). Hasil standarisasi parameter spesifik ektrak etanol labu kuning berbentuk kental, bau khas, warna coklat kekuningan, dan rasa pahit. Pada uji kualitatif, semi kuantitatif dengan KLT, dan kuantitaif untuk mendeteksi kandungan senyaawa metabolit sekunder fenol menunjukkan hasil positif mengandung fenol dengan kandungan fenol total sebesar 0,74 µg/mL sampel uji. Pada parameter non spesifik ekstrak labu kuning, didapatkan hasil untuk pengukuran pH sebesar 4,56; Bobot jenis 1,01 g/mL; Cemaran Mikroba dengan metode ALT 0x106  koloni/gram (memenuhi standar).Pumpkins is one of the plants that its fruit uses and thought to be active as antioxidant and also contains carotenoids which are rich in water-soluble vitamins, phenolics, polysaccharide flavonoids, mineral salts, and vitamins. Standardization of extract is carried out to ensure the quality of a traditional medicinal raw material to be used as a preparation which will also have an effect on the quality of the preparation and its therapeutic effect. Standardization of the ethanol extract of pumpkin was carried out with specific parameters that have been used in this research are organoleptic tests based on the five senses (shape, smell, colour and taste), qualitative phenol tests based on color reagents, semi-quantitative phenol tests using the TLC method (Thin Layer Chromatography), and quantitative  total phenol test using Folin-Ciocalteau reagent and gallic acid as a standard. The non-specific parameters carried out were checking the pH of the extract using a pH meter, density of extract, and microbiogical contamination levels was carried out by Total Plate Count (TPC).  The results of standardization specific parameters of ethanol extract of pumpkin are thick, have a distinctive smell, yellowish brown, and tastes bitter. In qualitative, semi-quantitative tests with TLC, and quantitative to detect total phenol as secondary metabolites, the results showed that positive results containing phenol with a total phenol content is 0.74 µg / mL in the test sample. For non-specific parameters of ethanol extract of pumpkin, the results for pH measurements were 4.56; density of extract 1.01 g/mL; Microbial contamination used TPC method 0 x 106 colonies/gram.
