There are a lot of efforts to develop new compounds having skin whitening effect from natural products. Sparassis crispa is a medicinal mushroom containing more than 40% β-glucan, which exhibits anticancer and immunostimulating effects. The aim of this study was to assess the availability of β-glucan extracted from cauliflower mushroom S. crispa as a skin whitener through the evaluation of inhibitory effects of melanin synthesis and tyrosinase activity and their mechanisms. B16F1 cells were treated with S. crispa β-glucan (10, 100, and 1,000 ㎍/ml, respectively) and α-melanocyte stimulating hormone (α-MSH), simultaneously. Content of melanin synthesis and tyrosinase activity were determined. The expressions levels of tyrosinase, tyrosinase related protein-1 (TRP-1), TRP-2 and microphthalmia-associated transcription factor (MITF) were also measured by western blotting. Treatment with 10, 100 and 1,000 ㎍/ml S. crispa β-glucan and 200 nM α-MSH significantly decreased melanin synthesis by 13.9%, 18.7% and 39.5%, respectively, and tyrosinase activity by 15.6%, 26.9% and 43.2%, respectively, compared to the α-MSH alone group. In addition, S. crispa β-glucan inhibited expressions of tyrosinase, TRP-1, TRP-2 and MITF induced by α-MSH. These results indicated that S. crispa β-glucan inhibited MITF expression, thereby reducing tyrosinase expression and inhibiting melanin production in B16F1 melanoma cells. Therefore, S. crispa β-glucan might be available as a skin whitener.

Objective : Sparassis crispa has been recognized for its therapeutic value since the late 20th century because of its high β-glucan content. Since then, researches have been conducted on the pharmacological effects but most of these are individual studies on the effects of β-glucan from S. crispa and the comprehensive reviews are lacking. The purpose of this study was to review the compounds composition and pharmacological effects of S. crispa. Methods : This review analyzes the papers about chemical and nutritional composition and pharmacological effects of S. crispa. The data in this review is based on selected papers after reviewing all studies containing the keyword "sparassis crispa" for PubMed, NDSL, and J-Stage published before February 2019. Results : S. crispa is composed of protein, lipids, and carbohydrates. Most of the compounds are carbohydrates and the highest content is β-glucan. More than 40% of the dried fruiting body of S. crispa is composed of β-glucan. In addition, it contains polyphenols, flavonoids, terpenoids and phthalide-based compounds. Broad spectrum of its pharmacological actions have been established which include immunomodulatory, anticancer, antiinflammatory, antioxidant, hypoglycemic, antiobesic and neuroprotective effects. Conclusion : The most studied fields have been shown to have immunomodulatory and anticancer effects by inhibiting the proliferation of cancer cells and angiogenesis and increasing hematopoitic responses. Unique structure and characteristic of high molecular weight β-glucan are considered to have high immunomodulatory effects of S. crispa. And low molecular fractions or phthalides of S. crispa also have antioxidant, immunomodulatory and anticancer effects.

The objective of this study was to investigate the nutritional composition and antioxidant activity of a mixture of rice bran and bodies of Sparassis crispa fermented with lactic acid bacteria (LAB). LAB-fermented S. crispa mixture had higher water, crude lipid and crude ash content than that of S. crispa. Insoluble dietary fiber contents of the dried powder of S. crispa and LAB-fermented S. crispa mixture were 46.13% and 33.46%, respectively. ${\beta}$-glucan was higher in dried S. crispa (38.03%) than in LAB-fermented S. crispa mixture (5.44%). Dried S. crispa contained mainly fructose and glucose instead of containing sucrose in LAB-fermented S. crispa mixture. No significant differences in the total polyphenol contents were found in between dried S. crispa and LAB-fermented S. crispa mixture. Total flavonoid content was significantly higher in LAB-fermented S. crispa mixture than in dried S. crispa. No significant differences were found in the DPPH radical scavenging activity and in the antioxidant index between dried S. crispa and LAB-fermented S. crispa mixture. Finally, ABTS radical scavenging activity of LAB-fermented S. crispa mixture was significantly higher than that of dried S. crispa. These results may provide the basic data for future studies for a better understanding of the biological activities of LAB-fermented S. crispa mixture.

The aims of this study were to investigate the quality characteristics of yellow layer cake added with Sparassis crispa powder that were abundant in dietary fiber, and also to determine the most suitable amount of added S. crispa powder. Dried powder of S. crispa containing 61.8 g/100 g insoluble dietary fiber was added to the cake batter in Baker's percentage of 1%, 2%, 4%, and 8%. Cake batter containing 1% and 2% S. crispa powder showed similar pH, specific gravity, and viscosity values to the batter without S. crispa powder (control). As the amount of added S. crispa power increased, the volume, specific volume, baking loss, and brightness (for both crust and crumb) of the cake containing the powder tended to decrease. A greater amount of added S. crispa powder resulted in a decrease in hardness, gumminess, and chewiness of the cake containing the powder and also reduced the changes in hardness of the cake during 8 days of storage. The sensory analysis showed that cake containing 2% S. crispa had several desirable kinds of sensory attributes, such as color, flavor, taste, and texture compared to the control; whereas an addition of more than 2% S. crispa deteriorated the sensory quality of the cake. These results suggest that the most suitable amount of added S. crispa powder for preparing yellow layer cake was 2% in Baker's percentage.

Cultivation characteristics of 12 strains of cauliflower mushroom (Sparassis crispa) collected in Korea were investigated by growing the mushroom on sawdust medium of Larix kaempferi. As cultivation characteristics, incubation period for full growth of mycelium in a cultivation bottle, cultivation time period taken for first harvest, and mushroom color and yield were examined. S. crispa KFRI 723 showed the shortest for incubation period with 59 days while S. crispa KFRI 746 showed the longest with 94 days. The earliest mushroom harvesting was achieved by 29 days from S. crispa KFRI 746 and the latest was by 63 days from S. crispa KFRI 691. The colors of fruit body of the tested strains can be divided into three groups; S. crispa KFRI 700 was white, S. crispa KFRI 747 was yellow brown, and the others were light yellowish. KFRI 700 yielded the most as 163 g from 380 g sawdust media, while KFRI 746 and KFRI 747 were the lowest with 58 g and 35 g, respectively. As results of cultivation characteristics of 12 strains of cauliflower mushroom, we consider that three strains (KFRI 700, 723 and 724) of S. crispa are suitable for sawdust cultivation on L. kaempferi in the aspects of mycelial growth period, harvesting period and mushroom production, respectively.

Sparassis (S.) crispa is an edible mushroom abundant in dietary fiber and ${\beta}$-glucan. The aim of this study was to prepare extracts and residues of the fruit bodies of S. crispa fermented with Lactobacillus (L.) brevis and Monascus (M.) pilosus and to measure the remaining dietary fiber and ${\beta}$-glucan. Dried powder of S. crispa containing 64.4 g/100 g total dietary fiber (2.6 g/100 g soluble and 61.8 g/100 g insoluble dietary fibers) and 24.0 g/100 g ${\beta}$-glucan was used as the starting material for the extraction. Raw and fermented S. crispa were extracted with hot water and three kinds of aqueous ethanol (50, 70, and 90%, v/v), respectively. A hot water extract from S. crispa fermented with M. pilosus had greater soluble dietary fiber content (19.3 g/100 g) than that from raw S. crispa with 14.6 g/100 g soluble dietary fiber or that from L. brevis-fermented S. crispa with 8.2 g/100 g soluble dietary fiber. The yield of the extract was 16.6% of intial weight of dried S. crispa. After hot water extraction of S. crispa fermented with M. pilosus, residues containing 90.5 g/100 g total dietary fiber (1.3 g/100 g soluble and 89.2 g/100 g insoluble dietary fibers) were obtained, and the yield was 69.6% of intial weight of dried S. crispa. The residue (31.0 g/100 g) contained more ${\beta}$-glucan than raw S. crispa or M. pilosus-fermented S. crispa (24.4 g/100 g). The resulting hot water extract and residue from S. crispa fermented with M. pilosus would be suitable for use in preparing liquid and powdered health functional foods, respectively.

This study examined the immune response of Philippines eel (Anguilla bicolor) to the oral administration of fermented Sparassis crispa stipe extract for 6 weeks. The S. crispa extract fermented with Lactobacillus plantarum showed a higher total phenol content (301.68 ppm) and DPPH radical scavenging activity (63.9%) than those fermented with other strains. Therefore, L. plantarum was selected as a suitable starter culture for the fermentation of S. crispa stipe. The eels were fed a commercial diet supplemented with 1% of fermented S. crispa stipe extract for 6 weeks. The mortality rate of the eels fed the supplemented diet was significantly lower than those of the control after 6 weeks. The lysozyme activity of the serum was increased significantly (12.33 ${\rightarrow}$ 54.66 units) after 6 weeks in the eel fed supplemented diets of fermented S. crispa stipe. The serum of the eel fed the supplemented diet of the S. crispa stipe extract showed higher bactericidal activity. These results suggest that both the S. crispa stipe extract and fermented S. crispa stipe have strong potential to activate the innate immune response of the Philippines eel.
