| dc.description.abstract | This study was undertaken to evaluate the optimum culture condition for secondary mycelial growth and determine the nutraceutical attributes of P. eryngii. Various indigenous media such as potato dextrose broth, coconut water, rice bran broth, corn grit broth and soybean broth were evaluated. The effect of pH, temperature, illumination and agitation were determined. Dry weight of mycelia and volume loss after 10 days of incubation period were assessed to determine the optimum growth condition. On the other hand, the The secondary mycelia grew best on potato dextrose broth at a pH range of 5.0-8.5 incubated in air conditioned (23°C), alternating light and dark and agitated condition. Based on the mycochemical analysis, the mycelia contain essential oils, triterpenes, coumarins, fatty acids, antraquinones, tannins, steroids, phenols and alkaloids. However, anthrones, phenolic compounds and flavonoids were not detected. It also exhibited radical scavenging activity of 61.19% and contain a total phenolic of 22.29 mg GAE/g of sample. Moreover, the ethanolic extract did not exhibit antibacterial activity against E. coli and S. aureus. | |
