Objective To study the chemical constituents of the fruiting bodies of Hydnum repandum.Methods Separation and purification were performed on silica gel, Sephadex LH-20 and ODS CC. Their sturctures were established by 2D-NMR (1H-1HCOSY, HMQC, HMBC, and NOESY), MS, HR-MS spectra, and ORD data. Results Eleven compounds were obtained and identified as sarcodonin A ( Ⅰ ),scabronine B (Ⅱ), 3β-hydroxy-5α, 8α-epidioxyergosta-6, 22-dien (Ⅲ), (22E, 24R)-ergosta-7, 22-diene3β, 5α, 6β- triol (Ⅳ), (22E, 24R)-ergosta-7, 22-diene-3β-ol (Ⅴ), benzoic acid (Ⅵ), 4-hydroxylbenzaldehyde (Ⅶ), 4-monopropanoylbenzenediol (Ⅷ), ethyl-β-D-glucopyranoside (Ⅸ), thioacetic anhydride ( Ⅹ ), (2S, 2'R, 3S, 4R)-2-(2-hydroxyoctadecanoylamino) docosane-1, 3, 4-triol (Ⅺ). Conclusion All of the compounds are isolated from this fungus for the first time.

Objective: To explore the effects of individual materialism, social status on victimization, and to provide a reference for the intervention of campus bullying. Methods: A total of 2 597 grade 7 students representing 47 classes from 7 junior middle schools in Zhenzhou were administered with Material Values Scale, Peer Nomination Questionnaire and Victim Questionnaire. Hierarchical Linear Model was used in data analysis. Results: Peer rejection(γ=0.15, P<0.01) and individual materialism(γ=0.13, P<0.01) positively predicted victimization, while popularity negatively predicted victimization(γ=-0.05, P<0.01). Class materialism norm also could positively predict victimization(γ=0.82, P<0.01). Moreover, there was a significant interaction between class materialism norm and peer rejection(γ=0.30, P<0.05), and the results of simple effect showed that with the increase of materialism level, the negative impact of peer rejection on victimization was increasing(γ high=0.18, Z high=7.80; γ low=0.12, Z low=5.50, P<0.01). Conclusion Peer rejection, individual materialism, popularity and class materialism norm affect individual bullying, and class materialism norm could moderate the relationship between peer rejection and victimization.
