Polysaccharides and triterpenes are the major pharmacologically active components in Ganoderma lucidum or Lingzhi, a medicinal mushroom well known for its immunomodulating activity. The Ganoderma lucidum used for this experiment were cultivars (MG1, MG2, and MG5) cultivated in Thailand collected from Muang Ngai Special Agricultural Project under the Patronage of Her Majesty Queen Sirikit, Chiang Mai province. The objectives of this study were to select the appropriate Lingzhi cultivars for cultivation, to investigate suitable wood logs as well as to study the appropriate harvest time. Quantitative determinations were performed using colorimetry and high performance liquid chromatography (HPLC). The results of this study indicated that the optimal harvest time of Lingzhi was 110 days after cultivation, the wood logs suitable for Lingzhi growth were paper mulberry, and longan wood logs, and the appropriate Lingzhi cultivar for cultivation in Thailand was MG2 since it produced the highest total polysaccharide content. The broken spore walls provide the highest percentage yield of major chemical compounds, especially triterpenoids.
