The cultivation strategy of enhancing triterpenoid production in submerged cultures of Antrodia cinnamomea by adding monoterpenes

Structural diversity, fermentation production, bioactivities and applications of triterpenoids from several common medicinal fungi: Recent advances and future perspectives

Medicinal fungi are beneficial to human health and it reduces the risk of chronic diseases. Triterpenoids are polycyclic compounds derived from the straight-chain hydrocarbon squalene, which are widely distributed in medicinal fungi. Triterpenoids from medicinal fungal sources possess diverse bioactive activities such as anti-cancer, immunomodulatory, anti-inflammatory, anti-obesity. This review article describes the structure, fermentation production, biological activities, and application of triterpenoids from the medicinal fungi including Ganoderma lucidum, Poria cocos, Antrodia camphorata, Inonotus obliquus, Phellinus linteus, Pleurotus ostreatus, and Laetiporus sulphureus. Besides, the research perspectives of triterpenoids from medicinal fungi are also proposed. This paper provides useful guidance and reference for further research on medicinal fungi triterpenoids.

Metabolomic Profiling of Different Antrodia cinnamomea Phenotypes

Antrodia cinnamomea (AC) is a precious medicinal fungus with numerous therapeutic benefits. Based on the color appearance of its fruiting bodies, AC can be divided into red AC (RAC), yellow AC (YAC), and white AC (WAC); however, the differences in their metabolomic profiles remain unknown. This study aimed to analyze the metabolomic profiles of three different AC phenotypes and examine their relationship to the color appearance of fruiting bodies. The results showed that although RAC, YAC, and WAC appear to have a relatively similar profile of index triterpenoids, their total triterpenoid contents were significantly different. Among the annotated triterpenoids, many of them were highly present in RAC but not in YAC and WAC, and the relative contents of the four ergostanes (antcamphin F, antcamphin L, antcin B, and antcin K) and one lanostane (versisponic acid D) were found to be significantly different among AC phenotypes. The metabolomic profiles of the AC fruiting bodies demonstrated a total of 140 metabolites, and 41 of them were very different among AC phenotypes. This study indicates that red, yellow, and white AC can biosynthesize the diverse structures of triterpenoids, and RAC possesses a relatively higher contents of triterpenoids and diverse unannotated metabolites than YAC and WAC.

Terpenoids from the medicinal mushroom Antrodia camphorata: chemistry and medicinal potential

Covering: up to February 2020Antrodia camphorata is a medicinal mushroom endemic to Taiwan for the treatment of intoxication, liver injury, cancer, and inflammation. Owing to its rare occurrence and potent pharmacological activities, efforts have been devoted to identify its bioactive constituents, especially terpenoids. Since 1995, a total of 162 terpenoids including triterpenoids, meroterpenoids, sesquiterpenoids, diterpenoids, and steroids have been characterized. The ergostane-type triterpenoids (antcins) and meroterpenoids (antroquinonols) are characteristic constituents of A. camphorata. The terpenoids show anti-cancer, hepatoprotective, anti-inflammatory, anti-diabetic, and neuroprotective activities. This review summarizes the research progress on terpenoids in A. camphorata during 1995-2020, including structural diversity, resources, biosynthesis, pharmacological activities, metabolism, and toxicity. The medicinal potential of the terpenoids is also discussed.

Alpha-terpineol affects synthesis and antitumor activity of triterpenoids fromAntrodia cinnamomeamycelia in solid-state culture

To enhance production ofAntrodia cinnamomeatriterpenoids (ACTs) from mycelia in solid-state culture, α-terpineol was added to the medium as an elicitor at an optimal concentration of 0.05 mL L⁻¹.
