An extensive research review of existing scientific findings involving bioactive compounds in Ganoderma Lucidum and the physiological effects of these compounds.
Researchers compared the tumour inhibitory effects of Ganoderma spores broken by two methods. Sporoderm-broken spores broken by enzymatic method had improved inhibitory effect on cancer cell growth c.f. physically-broken spores.
Certain cancer therapy agents can cause cardiotoxicity. Recent research reveals that Ganoderma spore oil demonstrates promising anti-cancer and cardioprotective effects.
Ergosterol peroxide, within Ganoderma Lucidum oil, is a key bioactive compound that inhibits tumour growth by reducing reducing cancer cell survival and migration. In this study, researchers investigated how, ergosterol peroxide causes cell death among liver cancer cells.

Ganoderma lucidum, a traditional Chinese medicinal fungus, has been a favourite remedy in oriental medicine for centuries. The objective of this study is to analyze whether G. lucidum affects cancer cell proliferation and cell death. Malignant human breast carcinoma cells were used in our studies. Different preparations of G. lucidum spores were added to the cancer cells at a final concentration of 1 mg/ml followed by incubation of the cultures for two days. Treatment with G. lucidum resulted in tumour cells detachment from the tissue culture plates and death. The proliferation of the adherent cells was also inhibited. The experiments indicated that the inhibitory effects of G. lucidum on cancer cell growth were sporoderm-broken spores (broken by enzymatic method) > sporoderm-broken spores (broken by physical method) > intact spores > buffer control....

Ganoderma lucidum is a herbal mushroom known to have many health benefits, including the inhibition of tumor cell growth. However, the effect of Ganoderma lucidum on epithelial ovarian cancer (EOC), the most fatal gynecological malignancy, has not yet been reported. In this study, we determined whether Ganoderma lucidum regulates EOC cell activity. Using several cell lines derived from EOC, we found that Ganoderma lucidum strongly decreased cell numbers in a dose-dependent manner. Ganoderma lucidum also inhibited colony formation, cell migration and spheroid formation. In particular, Ganoderma lucidum was effective in inhibiting cell growth in both chemosensitive and chemoresistant cells and the treatment with Ganoderma lucidum significantly enhanced the effect of cisplatin on EOC cells. Furthermore, Ganoderma lucidum induced cell cycle arrest at the G2/M phase and also induced apoptosis by activating caspase 3. Finally, Ganoderma lucidum increased p53 but inhibited Akt expression. Taken together, these findings suggest that Ganoderma lucidum exerts multiple anti-tumor effects on ovarian cancer cells and can enhance the sensitivity of EOC cells to cisplatin.

This study was carried out to isolate chemical constituents from the lipid enriched fraction of Ganoderma lucidum extract and to evaluate their anti-proliferative effect on tumor cells and human umbilical vein endothelial cells (HUVECs). Ergosterol derivatives (1–14) were isolated and purified from the lipid enriched fraction of G. lucidum. Their chemical structures were established by spectroscopic analyses or by comparison of mass and NMR spectral data with those reported previously. Amongst, compound 1 was purified and identified as a new one. All the compounds were evaluated for their anti-proliferative effect on human tumor cells and HUVECs in vitro. Compounds 9–13 displayed inhibitory activity against two types of human tumor cells and HUVECs, which indicated that these four compounds had both anti-tumor and anti-angiogenesis activities. Compound 2 had significant selective inhibition against two tumor cell lines, while 3 exhibited selective inhibition against HUVECs. The structure–activity relationships for inhibiting human HepG2 cells were revealed by 3D-QASR. Ergosterol content in different parts of the raw material and products of G. lucidum was quantified. This study provides a basis for further development and utilization of ergosterol derivatives as natural nutraceuticals and functional food ingredients, or as source of new potential antitumor or anti-angiogenesis chemotherapy agent.
The present invention relates to a method for preparing Ganoderma spore oil which is in the field of biotechnology. The method includes using Ganoderma spore powder and Ganoderma powder (obtained from grinding fruiting bodies) as raw materials, applying enzymatic Ganoderma sporoderm broken methods, one-step granulation, supercritical CO2 extraction method, as well as centrifugation and refining. The light yellow oleaginous substances obtained posses a variety of physiological functions such as strengthening immunity, protecting the liver and inhibiting tumor cell growth, etc. Ganoderma spore oil prepared with the present technology contains not only spore extracts, but also extracts from Ganoderma fruiting bodies and mycelium by CO2 supercritical extraction, with more types of triterpenoids. The inhibitory effects of Ganoderma spore oil is a onefold higher than spore oil prepared from the physical preparation of the sporoderm-broken spore. Meanwhile, the problem of spore oil spoilage arising from oxidation is solved due to the low peroxide value within Ganoderma spore oil, and thereby the quality of Ganoderma spore oil is greatly improved.

Complementary and alternative medicines have attracted increasing attention as disease treatments, adjuvants, and alternative supplements [1-4]. Medicinal mushrooms comprise a large proportion of these alternative products, among which Ganoderma lucidum is the most highly studied [5-8]. Preclinical studies have demonstrated anti-tumorigenic roles in a range of medicinal mushrooms [9-11]. A Cochrane meta- analysis showed that patients who had been administered Ganoderma lucidum alongside chemo/radiotherapy were more likely to respond positively compared to chemo/radiotherapy alone. These trials demonstrated improved immune functions as measured by increased CD3, CD4, and CD8 immune response cells . In vitro, Ganoderma lucidum was also found to inhibit proliferation and induce apoptosis in ovarian, colon, and gastric cancer cell lines [13-15]. Ganoderma lucidum contains beta glucans and other polysaccharides which stimulate innate immunity and activate host dendritic cells [16, 17]. Ganoderma lucidum also produces a group of ganoderic acids, which have molecular structures that are similar to steroids [18, 19].
