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.

Sparassis crispa (Wulf.) is an edible/medicinal mushroom and has been reported to biological activities such as antitumor, anti-angiogenesis, antioxidant and wound healing. However, there have not been many researches on osteoarthritis of S. crispa. The aim of this study was to investigate the effects of S. crispa extract on rats with osteoarthritis induced by MIA. Osteoarthritis is a gradually developmental disease that early stage, causes joint stiffness and complains of joint pain. In addition, it gives rise to edema and hypo-function. The results of this study, S. crispa extract effectively inhibited ROS production, increased the production of antioxidant protein SOD and catalase in knee joint cartilage tissue. In addition, S. crispa extract inhibited the expression of pro-inflammatory cytokines and enzymes such as NOX4 and $P47^{phox}$, which are involved in the expression of COX-2, iNOS and the production of ROS. Also, S. crispa extract inhibited the destruction of synovial tissue, cartilage tissue and proteoglycans in articular cartilage in rats.

Six strains of Sparassis crispa such as S. crispa DUM-01, DUM-02, DUM-03, DUM-04, DUM-05, and DUM-06 were tested for their mycelial growth on 6 different kinds of sawdust media and primordial formation on 10 different compositions of larch sawdust media. The highest mycelial growth was recorded on the larch sawdust. Of the 6 strains of S. crispa, S. crispa DUM-04 recorded the favorable formation of primordia. The primordial formation of S. crispa DUM-04 was more favorable on L-3 medium than 9 kinds of larch sawdust media. When S. crispa DUM-04 was cultured on the media of larch sawdust+pine sawdust, the formation of its fruiting bodies was more outstanding on the media of larch sawdust+pine sawdust than those of larch sawdust.

A chemical mutagenesis technique was employed for development of mutant strains of Sparassis crispa targeting the shortened cultivation time and the high ${\beta}$-glucan content. The homogenized mycelial fragments of S. crispa IUM4010 strain were treated with 0.2 vol% methyl methanesulfonate, an alkylating agent, yielding 199 mutant strains. Subsequent screening in terms of growth and ${\beta}$-glucan content yielded two mutant strains, B4 and S7. Both mutants exhibited a significant increase in ${\beta}$-glucan productivity by producing 0.254 and 0.236 mg soluble ${\beta}$-glucan/mg dry cell weight for the B4 and S7 strains, respectively, whereas the wild type strain produced 0.102 mg soluble ${\beta}$-glucan/mg dry cell weight. The results demonstrate the usefulness of chemical mutagenesis for generation of mutant mushroom strains.

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.

Sparassis crispa is an edible mushroom with medicinal properties that contains more than 40% ${\beta}$-glucan. The role of S. crispa in regulating the functional activation of macrophages has yet to be fully elucidated. The objective of this study was to investigate the molecular mechanism underlying the immune-stimulatory function of S. crispa soluble ${\beta}$-glucan and extracts on macrophages. In this study, we showed that S. crispa soluble ${\beta}$-glucan was able to stimulate TNF-${\alpha}$ and IL-$1{\beta}$ production through NF-${\kappa}B$ activation in Raw 264.7 cells. We also showed that S. crispa extracts could not only enhance TNF-${\alpha}$ production in Raw 264.7 cells, but also suppress tumor growth in vivo. All of our results suggest that S. crispa could be developed as a promising immunostimulatory principle, applicable to cancer patients.

Sparassis crispa fruits were extracted in 80 % MeOH, and the concentrated extract was partitioned into EtOAc, n-butyl alcohol, and water fractions. The repeated octadecyl $SiO_2$ and silica gel ($SiO_2$) column chromatographies for the EtOAc and nbutyl alcohol fractions led to isolation of two ergosterol peroxides. There chemical structures were determined as ($3{\beta}$,$5{\alpha}$,$8{\alpha}$,22E)-5,8-Epidioxyergosta-6,22-dien-3-ol (ergosterol peroxide) (1) and 3-O-${\beta}$-D-glucopyranosyl ergosterol peroxide (2) based on spectroscopic data analyses including nuclear magnetic resonance, infrared spectrometry, and mass spectrometry (MS). Compounds 1 and 2 were for the first time isolated from S. crispa in this study.
