Kajian pendahuluan uji toksisitas ekstrak air miselia dan tubuh buah jamur shitake (Lentinus edodes) dengan metode brine shrimp lethality test (BTS)

Abstract

Shiitake mushroom (Lentinus edodes) is one of the wood mushroom types that can be consumed as a food as well as for a medicalpurpose. Lentinan, a polysaccharide contained in shiitake, is well known for its use on cancer medication. Mycelium of Shiitake mushroomcontains lentinan the same as other part of the mushroom like fruity body. Toxicity of the lentinan in mycelium compare to the fruitybody has been first conducted by using Brine Shrimp Lethality Test (BST). Using Potato Dextrose Broth media with the growth rate of3.88% did mycelium multiplications. Probit analysis showed that the toxicity of the mushroom’s cap, stem, and mycelium of Shiitakemushrooms is LC50 = 648.76507 mg/ml LC50 = 489.39444 mg/ml, and LC50 = 481.16941 mg/ml respectively.
