“…Several researchers have recently presented a correlation between total phenolic content and antioxidant activity in mushroom extracts [1,2,15]. The correlation for reducing power and scavenging effect on superoxide anion is built by taking into consideration that various phenolic contents are present in fermented A. mellea mushroom extracts.…”

Antioxidant components, ascorbic acid, total flavonoids and total phenols are produced effectively by Armillaria mellea submerged cultures. Dried mycelia and mycelia-free broths obtained by A. mellea submerged cultures are extracted with methanol and hot water and investigated for antioxidant properties. Methanolic extracts from dried mycelia (MEM) and mycelia-free broth (MEB) and hot water extracts from dried mycelia (HWEM) by A. mellea submerged cultures show good antioxidant properties as evidenced by low EC50 values (<10 mg/mL). Total flavonoid is mainly found in hot water extracts; however, total phenol is rich in methanol and hot water extracts from mycelia. Ascorbic acid and total phenol contents are well correlated with the reducing power and the scavenging effect on superoxide anions. Total flavonoid content is dependent on the antioxidant activity and the chelating effect on ferrous ions. Total antioxidant component contents are closely related to the antioxidant activity and the scavenging superoxide anion ability. Results confirm that extracts with good antioxidant properties from fermenting products by A. mellea are potential good substitutes for synthetic antioxidants and can be applied to antioxidant-related functional food and pharmaceutical industries.

“…Therefore, the capacity of the prostate is decreased [21,22]. Phellinus linteus can also be seen as a natural antioxidant and anti-cancer food as it contains large amounts of polyphenol ingredients including β-glucan and flavonoid [23,24]. Accordingly, it appears that various antioxidant ingredients of Phellinus linteus extract and the physiological chemical action caused by β-glucan are valid in the rat model; hence, statistically, significant decreases in the bulk and weight of the prostate in Phellinus linteus -injected group was observed when compared to the benign prostatic hyperplasia induced group.…”

Benign prostatic hyperplasia (BPH) is one of the most common diseases among elderly men. As the old-age population is increasing recently, it is to our interest to observe the growing BPH within them. In BPH, the dihydrotestosterone (DHT) acts as promotes prostate growth. It inhibits enzyme 5α-reductase that is involved in the conversion of testosterone to the DHT activity which reduces the excessive prostate growth. Through experiments, the effects of Phellius linteus water extract performed on the BPH rats were induced by testosterone treatments. For 12 weeks, Sprague-Dawley rats were treated with testosterone for the induction of BPH. Rats were divided into four experimental groups: the not treated group (N), the testosterone injection and D.W treatment group (TN), the testosterone injection and Phellinus linteus treatment group (TP) and testosterone injection and finasteride treatment group (TF). Prostate weight, volume and weight ratio in the TP group and the TF group were significantly lower than the TN group. Testosterone and DHT levels in the TN group were significantly higher than that of the N group. And the TP group was significantly decreased than that of the TN group. While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation; the TP and TF groups showed trophic symptoms and were lined by flattened epithelial cells, thus, the stromal proliferation is relatively low as compared to the TN group. These suggest that Phellinus linteus water extracts may be an useful remedy for treating the benign prostatic hyperplasia.

In the present study, Premna microphylla turcz leaves (PMTLs) containing rich pectin and isoflavones were introduced to prepare packed tofu coagulated by lactic fermentation, in order to promote its physicochemical and functional properties. Results showed that the final storage (G 0 ) moduli of packed tofu added with PMTL extracts range from 195.2 AE 5.6 Pa to 420.6 AE 10.3 Pa, which were significantly higher (P < 0.05) than the control (PMTL-free, 99.5 AE 8.3 Pa). The hardness, gumminess and chewiness of packed tofu added with 0.8% (w/w) PMTL extracts were 1.43-1.49 times higher than the control without decreasing its water-holding capacity and exhibited the highest scores of overall acceptability, which was recommended as the most acceptable concentration. The total phenolic and flavonoid contents of 0.8%-PMTL supplementation in packed tofu were 1.20 and 1.65 times higher than the control and showed enhanced antioxidant properties in DPPH radical-scavenging capacity, FRAP and RP.Addition of PMTL changed the quality of tofu Z.
