In this study, the anti-inflammatory and anti-oxidative activities were compared for the extracts of non-fermented Ligustrum japonicum fruits (LJF) and fermented counterparts. U se of Latilactobacillus curvatus (L. curvatus) and Weissella minor (W. minor), isolated from the Jeju Chromis notata, as fermented strains led to the extracts of LJF-LC and LJF-WM in this experiment. The yield of each fermented extract (LJF-LC and LJF-WM) was 40.5 ~ 46.0%, higher than 29.5% of non-fermented extract (LJF). As a result of an activity experiment using RAW 264.7 macrophages stimulated by lipopolysaccaride (LPS), it was confirmed that LJF-WM, a fermented extract, has an excellent effect of inhibiting NO production in a concentration-dependent manner without cytotoxicity. Upon the screening of DPPH and ABTS⁺ radical scavenging activities, the fermented LJF-LC and LJF-WM showed comparable to the non-fermented LJF. In the study of cell protection effect using HaCaT keratinocytes damaged by hydrogen peroxide (H₂O₂), the fermented LJF-WM indicated protective effect against oxidative stress. In addition, quantitative analysis of a major constituent salidroside by HPLC indicated about 15.6 mg/g for the LJF-LC and 13.9 mg/g for the LJF-WM, which were higher than that of non-fermented LJF (12.0 mg/g). Based on these results, it was suggested that the fermented extract from L. japonicum fruits could be used as a natural cosmetics material with anti-inflammatory and anti-oxidative effects.

The Acer tegmentosum (3 kg) were extracted with boiled water and the freeze dried extract powder was partitioned with $CH_2Cl_2$, EtOAc, n-BuOH and $H_2O$, successively. From the EtOAc and n-BuOH fraction, six phenolic compounds were isolated through the silica gel, octadecyl silica gel and sephadex LH-20 column chromatography. On the basis of spectroscopic methods, such as $^1H$-NMR and $^{13}C$-NMR, and LC/MS, the chemical structures of the compounds as feniculin (1), avicularin (2), (+)-catechin (3), (-)-epicatechin (4), salidroside (5) and 6'-O-galloylsalidroside (6). In this study, compounds 1 and 2 have been first isolated from the A. tegmentosum. To provide insight into the effects of six compounds isolated from A. tegmentosum on inflammation, we investigated its effect on nitric oxide (NO) production in RAW 264.7 cells using lipopolysaccharide (LPS) stimulation. Compounds 1 and 6 slightly repressed NO production. Also, compounds 3 and 4 inhibited NO secretion with statistical significance. However, compounds 2 and 5 did not show any inhibitory effect on NO production.

Twenty-five compounds were isolated from the methanolic extract of Geum japonicum (Rosaceae), and their structures were identified as eleven triterpenoids [ursolic acid 3-acetate (2), cecropiacic acid 3-methyl ester (3), pomolic acid 3-acetate (5), ursonic acid (6), ursolic acid (7), pomolic acid (8), corosolic acid (9), euscaphic acid (11), arjunic acid (16), tormentic acid (18), 23-hydroxytormentic acid (21)], two saponins [rosamultin (22) and kaji-ichigoside $F_1$ (23)], two megastigmanes [blumenol A (14) and (+)-dehydrovomifoliol (15)], three flavonoids [apigenin (13), isoquercitrin (17) and tiliroside (24)], two ellagic acid derivatives [3,3'-di-O-methylellagic acid (12) and ducheside B (25)] and five others [eugenol (1), emodin (4), vanillic acid (10), gallic aldehyde (19), salidroside (20)]. The chemical structures of these compounds were identified on the basis of spectroscopic methods and comparison with literature values. This is the first report of the eleven compounds, 2~6, 10, 15, 16, 20, 23, and 25 from the genus Geum, as well as the first report of apigenin (13) and 3,3'-di-O-methylellagic acid (12) from G. japonicum. The antioxidant properties of 22 isolates (1~11, 14, 16~25) were evaluated by the intracellular reactive oxygen species (ROS) radical scavenging using 2',7'-dichlorodihydrofluorescein diacetate (DCF-DA) assay. Among them, isoquercitrin (17) showed significant scavenging activity, and gallic aldehyde (19) and ducheside B (25) showed weak scavenging activity.

Background: Ginseng (G) and Ligustrum lucidum Ait (LLA) are core traditional Chinese medicines in treating myelosuppression formula. The present study was designed to profile effect of G and LLA herb pair (G-LLA) on myelosuppressed mice. Methods: The mice myelosuppression model was established by intraperitoneal (i.p.) injection of cyclophosphamide (Cy). Hematopoietic function of bone marrow was measured by hemopoietic progenitor cell culture and peripheral blood count, and serum hemopoietic factors were tested by enzyme-linked immunosorbent assay. Bone marrow cell cycle was performed by flow cytometry. HPLC was used to measure 20 potential chemical components related to myelosuppression, including ginsenoside Rg₁, Re, Rb₁, Rc, Rb₂, Rb₃, Rd, Rk₃, Rh₄, 20 (S)-Rg₃, 20 (R)-Rg₃, Rk₁, Rg₅, salidroside, and so on. Results: G, LLA, and G-LLA improved the amount of peripheral blood cells and bone marrow cells of myelosuppressed mice (P < 0.01). They significantly increased the colony quantity of colony-forming unit-granulocyte macrophage, burst-forming unit-erythroid, colony-forming unit-erythroid, and colony-forming unit-megakaryocyte and amount of G₂/M and S phase cells (P < 0.01). They also significantly decreased the amount of hematopoiesis-related cytokines (P < 0.01). The content of chemical components in G-LLA changed, and the change of rare saponin was the most obvious. Conclusion: These results show that G-LLA herb pair might produce synergistic or complementary compatibility effects on bone marrow suppression after chemotherapy. It suggests that the substance basis of G-LLA for treating bone marrow suppression may be effective chemical components.

The transitivity of Chemical constituents by Pleurotus ostreatus cultivated in different raw sawdusts, which are Acer tegmentosum MAX, Rhus verniciflura, was investigated. The HPLC chromatography patterns on the chemical constituents of P. ostreatus showed the similar chromatography patterns in the different raw sawdusts and control sawdust. The unknown chemical constituents of P. ostreatus cultivated in the mixed medium added 10 %, 20% raw sawdusts, respectively, were increased. But the significance results in the mixed medium added 50% raw sawdusts were not showed. The chromatography patterns of mycelia grown in media added the 80% MeOH extracts of A. tegmentosum and R. verniciflura showed the similar patterns in comparison with control mycelia. In the results, the secondary metabolites of functional media were not degrade and changed to other derivatives compounds by P. ostreatus.
