“…Bioactive potential of wild mushrooms are increasingly recognised owing to a wide range of properties like radical-scavenging, antimicrobial, anticancer, antidiabetes, hepatoprotective, cosmeceutical and nutricosmetic potentials (Lindequist et al 2005; Biswas et al 2011b; Kalogeropoulos et al 2013; Shameem et al 2015; Smith et al 2015; Taofiq et al 2016). Recently, mushroom-based antioxidants have attracted wide attention worldwide against synthetic antioxidants (e.g.…”

The wild mushroom Astraeus hygrometricus is a traditional delicacy during the monsoon season in South-western India. Bioactive principles and antioxidant potential of uncooked and pressure-cooked tender mushroom have been evaluated. Seven bioactive principles of mushroom (tannins, flavonoids, vitamin C, phytic acid, lycopene, β-carotene and trypsin inhibition) were significantly higher, while total phenolics content was significantly lower in uncooked than in cooked samples. Mushroom was devoid of L-DOPA, whereas only uncooked samples showed haemagglutinin activity against A+ blood group. The principal component analysis of uncooked mushroom showed only two bioactive principles clustered with two antioxidant properties, while in cooked mushroom five bioactive principles clustered with three antioxidant properties depicting the nutraceutical potential of cooked mushroom. Future studies should focus on appropriate thermal treatment, which retain maximum bioactive and antioxidant potential to combat health- and lifestyle-related ailments. The A. hygrometricus is ectomycorrhizal, conservation of its host tree species is utmost importance in improvement and expansion of its yield to sustain food security and economic gains of local tribals.

“…Improvement of human health by shiitake mushroom is usually explained by chemical compounds such as lentinan, eritadenine, and l-ergothioneine. It contains also anti-oxidants and vitamins A, C, D, E (Mau et al, 2002;Smith et al, 2002;Baba et al, 2015;Smith et al, 2015). Besides application for the improvement of human health this mushroom can be very efficiently used also in the feeding and veterinary treatment of various animals.…”

The effects of hot water extraction (HWE), enzyme‐assisted extraction (EAE), ultrasonic‐assisted extraction (UAE), and ultrasonic‐enzyme‐assisted extraction (UEAE) methods on the extraction yield, physicochemical properties, and antioxidant activities of Gynura medica polysaccharides (GMPs) were investigated. The GMPs extracted by four methods were designated GMPs‐H, GMPs‐E, GMPs‐U, and GMPs‐UE, respectively. Meanwhile, the EAE method was further optimized by response surface methodology (RSM). The results showed that EAE and UEAE methods both markedly enhanced the yield of GMPs. Four kinds of GMPs possessed different physicochemical properties including molecular weight distributions and surface morphology. EAE had higher scavenging abilities for DPPH radical compared to other methods. The optimal conditions for GMPs were predicted to be cellulase amount of 155 (mg/g), extraction time of 48.4 min and pH of 7.9, with a predicted yield of 11.98%. Under the optimal conditions, the yield of polysaccharides was 12.03%, which matched the predicted value well. Practical applications Enzyme‐assisted extraction (EAE) is an environmentally friendly method that can be used to improve the extraction of active ingredients from various natural sources. Our results demonstrated that EAE could enhance the extraction yield of polysaccharides which was the most important active ingredient. In addition, Gynura medica polysaccharides possess good antioxidant activity, which means that Gynura medica polysaccharides may be a novel source of natural antioxidant in functional food.
