RESUMEN
This study investigated the nutritive properties of the culinary-medicinal mushroom Auricularia auricula- judae. From the analysis, among the major minerals, potassium was found in the highest concentration, with a value of 172.03 ± 8.62 mg/kg, whereas manganese had the highest concentration among trace elements, with a value of 1.66 ± 0.11 mg/kg. Glutamic acid was the amino acid detected in the largest amounts in this study, with a value of 10.09 ± 1.86 mg/kg. Although glutamine and asparagine were not detected in this mushroom, cysteine and methionine had the lowest concentrations, with values of 0.34 ± 0.01 and 0.80 ± 0.03 mg/kg, respectively. The predominant oil was 9,12-octadecadienoic acid (Z,Z)methyl ester, with retention times of 21.246 and 21.715 minutes, and comprising percentages of the total of 4.309 and 47.385, respectively.

Gas chromatography-mass spectrometry analysis of constituent oil from dried Ganoderma lucidum was carried out. Fresh G. lucidum obtained from its natural environment was thoroughly washed with distilled water and air-dried for 2 weeks and the component oils were extracted and analyzed. Four predominant components identified were pentadecanoic acid, 14-methyl-ester (retention time [RT] = 19.752 minutes; percentage total = 25.489), 9,12-octadecadienoic acid (Z,Z)- (RT = 21.629 minutes and 21.663 minutes; percentage total = 25.054), n-hexadecanoic acid (RT = 20.153 minutes; percentage total = 24.275), and 9-octadecenoic acid (Z)-, methyl ester (RT = 21.297 minutes; percentage total = 13.027). The two minor oils identified were 9,12-octadecadienoic acid, methyl ester, (E,E)- and octadecanoic acid, methyl ester (RT = 21.246 minutes and 21.503 minutes; percentage total = 7.057 and 5.097, respectively).
