“…The FDLF extracts were found to be significantly (P < 0.05) stronger radical scavenger than FLF at all maturity stages tested with all IC 50 values of lower than 10 mg/ml. This is in accordance to Lee et al (2007) who reported that IC 50 values lower than 10 mg/ml are indicative of the effective antioxidant activity. Freeze drying process has been popularly applied in laboratory practice and food industry to preserve fresh plant material.…”

Antioxidant and phytochemical compounds of fruits can vary widely depending on many factors such as processing and maturity stage as one of the major contributors. Therefore, this study investigated the antioxidant activity and phytochemical attributes of fresh and freeze-dried Lepisanthes fruticosa fruit extracts at eight different maturity stages. The freeze-dried extracts were obtained by lyophilisation using a freeze-dryer. In general, antioxidant activity and phytochemical contents of both fresh (FLF) and freeze-dried (FDLF) extracts showed a decrease with fruit maturation. Among the eight maturity stages developed for L. fruticosa, the lower maturity (unripe) stages exhibited the strongest potential, with stage 1 being the most notable. The FDLF fruit extracts were found to be significantly (P < 0.05) stronger radical scavenger than FLF extracts at all maturity stages tested. The IC 50 values of FDLF for the eight maturity stages were more effective, with stage 1 showing the lowest IC 50 (1.57 mg/ml). Total phenolic content of FDLF was also significantly (P < 0.05) higher than FLF at all eight stages tested, with the highest also being shown at stage 1 (15848.96 ± 401.82 mg/100 g). On the contrary, FLF extracts displayed significantly (P < 0.05) higher total flavonoid content than FDLF at almost all stages except for 2, 3 and 6. The highest content was shown in stage 1 with 37.35 ± 0.77 mg/100 g. These findings showed that antioxidant activity and phytochemical content of L. fruticosa fruits were significantly affected by processing and maturity. The obtained results are important for the promotion of use of L. fruticosa fruit extracts as a natural antioxidant in functional food production in the future.

“…The IC 50 values of FDLF for the eight maturity stages ranged from 1.57-6.51 mg/ml. Lee et al (2007) reported that IC 50 values lower than 10 mg/ml are indicative of the effective antioxidant activity. However, there was no significance difference (P < 0.05) shown among FDLF extracts when they compared to each other.…”

“…Similar antioxidant properties have also been reported for other edible mushrooms, including Agrocybe cylindracea and H. marmoreus, both of which belong to the Tricholomataceae family (Tsai et al, 2006). Potent antioxidant activity was also found in crude methanolic and aqueous extracts of the common Chinese edible mushrooms L. edodes (shiitake mushroom), Pleurotus tuber-regium and V. volvacea (straw mushroom) and a lesser known edible mushroom, A. aegerita, belonging to the family Bolbitiaceae, was evaluated by the β-carotene bleaching method, DPPH radical scavenging activity and erythrocyte hemolysis assay (Lee et al, 2007). Fractionation of the crude methanolic and aqueous extracts of L. edodes, P. tuber-regium and V. volvacea further indicated that the dichloromethane and ethyl acetate fractions of these mushrooms have the strongest antioxidant activity and have the lowest median effective…”

Abstract:Mushrooms have been known for their nutritional and culinary values and used as medicines and tonics by humans for ages. In modern terms, they can be considered as functional foods which can provide health benefits beyond the traditional nutrients. There are monographs that cover the medicinal and healing properties of some individual traditional mushrooms. There has been a recent upsurge of interest in mushrooms not only as a health food which is rich in protein but also as a source of biologically active compounds of medicinal value which include complementary medicine/dietary supplements for anticancer, antiviral, hepatoprotective, immunopotentiating and hypocholesterolemic agents. However the mechanisms of the various health benefits of mushrooms to humans still require intensive investigation, especially given the emergence of new evidence of their health benefits. In the present paper the medicinal potential of mushrooms is being discussed.

“…According to Lee et al, ethanolic and aqueous extracts of H. marmoreus had moderate antioxidative activities, suggesting that the major antioxidative components in the extracts were phenolic compounds. 1) It has been reported that proteins from H. marmoreus had growth-inhibiting actions against various fungal species and cancer cells. 2,3) However, among its various constituents, the biological activities of the water-soluble extracts have not been extensively studied.…”
