Free Amino Acids and Their Derivatives of Ganoderma lucidum

영지 버섯의 유리 아미노산 및 유도체에 관한 연구

To find active components in Ganoderma lucidum, their free amino acid and free amino acid derivatives were analyzed. After extracting with hot water, the extracts were filtrated by three steps. So, supernatants below 10,000 dalton were obtained. Filtrates were derivativated with PITC (phenylthiocarbamyl) derivative reagent and PITC amino acid was obtained. Then, they were analyzed by RP-HPLC. 13 amino acids were analyzed in cultured Korean Nok-kak ji (one of Ganoderma lucidum), 15 amino acids in cultured Korean Ganoderma lucidum, 12 amino acids wild Ganoderma lucidum, 16 amino acids in cultured Taiwan Ganoderma lucidum.
