Karakterisasi Simplisia dan Ekstrak Etanol Serta Uji Aktivitas Antioksidan Rimpang Jahe Merah (Zingiber Officinale Var. Vubrum Theilade) yang Diinokulasi Fungi Mikoriza Arbuskula (FMA)

ABSTRACT: Red ginger (Zingiber officinale var. rubrum Theilade) is one of Zingiberaceae’s family that has been used traditionally for curing asthma, cramps, diabetes, fever, infection, hypertension, muscleache, nausea, sorethroat, stroke, and toothache. Red Ginger Rhizome has been proven pharmacologically as the medicine for many diseases. The purpose of this research is to investigate the characteristization of simplicia and ethanol extract of red ginger rhizome which is inoculated by Arbuscular Mychorrizae Fungi (AMF), to determine the total phenolic level by using Folin – Ciocalteau’s method and antioxidant activity test by using Ferric Reducing Antioxidant Power (FRAP). The researchers used the red ginger rhizome from Bari Village, Padang Pariaman, West Sumatera. Sample sliced 3 mm,  macerated with using 70 % of ethanol solvent, so that will produce ethanol extract. From the characterization of simplicia of red ginger rhizome, we could know that it has brownish yellow with wedge shape and spicy taste with unique smell. The characterization of ethanol extract from red ginger rhizome is thick liquid with brownish yellow and spicy taste with unique smell. Parameter shrinkage drying 6.01% ± 0.22, total ash content is 7.42 % ± 0.86, ash content non soluble acid 0.94 % ± 0.26, the levels of soluble extract of water 13.55 % ± 1.11 and the levels of soluble extract of ethanol 5.31 % ± 0.25. The moisture content of extract is 9.33 % ± 1.53,  total ash content 14.79 % ± 0.86 and ash content non soluble acid 0.97 % ± 0.26. Total phenolic of AMF inoculated red ginger extract is 26,7324 g/100g with ntioxidant activity is 1.65 mmol Fe(II)/100 g
