  • Stachys affinis tubers are known for its high content of stachyose and eaten as an edible vegetable. In this work, we assessed on the anti-inflammatory and anti-proliferation activity of a various type of extracts derived from S. affinis tubers. The n-hexane and dichloromethane fractions were showed the high cytotoxicity on the cell lines including RAW264.7 macrophages, HEK293 human kidney cell, A549 human lung cancer cell, KB human oral cancer cell, and a PC-3 human prostate cancer cell. N-butanol and water fractions were not exhibited cytotoxicity on the tested cancer cells, limited in anti-inflammatory and anti-cancer activities. Nevertheless, the ethyl acetate fraction showed little harm to RAW264.7 cells but inhibited the production of nitric oxide (NO) and prostaglandin E2 (PGE2) significantly. In addition, it arrests the cell growth in A549, KB, and PC-3 cell while little cytotoxicity on HEK293 cells. Consequently, these results supported that the ethyl acetate fraction of S. affinis tubers could be a potential anti-inflammatory and anti-cancer ingredient.

  • The aim of the study was to determine the anti-inflammatory activities of the plants with origin of China. The Fissistigma poilanei, which is a species of plant in the family Annonaceae and Rubus laxus Focke, which is a species of plant in the family Rosaceae from China were tested for anti-inflammatory activities. Samples were prepared using 95% ethanol using nitric oxide (NO) assay for assessing the anti-inflammatory activity. NO assay experiment showed that extracts of the Fissistigma poilanei give 28.3% increases in anti-inflammatory activity and extracts of Rubus laxus Focke give 57.1% decreases in anti-inflammatory activity, compared to control. To determine the cell toxicity, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay was used. MTT assay experiment showed that Fissistigma poilanei and Rubus laxus Focke might have less toxicity of 60.5% and 62.3%, respectively, compared to control. Taken together, these experiments showed that Fissistigma poilanei extracts might have significantly higher anti-inflammatory activities and relatively lower toxicity, compared to control. This implies that this study might give a tool to develop a new potential anti-inflammatory therapeutic candidate.

  • Anti-inflammatory, anti-arthritic and analgesic activity of each herbal extract, which is extracted from Bacopa monnieriis, Cassia fistula and Phyllanthus polyphyllus, respectively. The treatment of herbal extract exhibited anti-inflammatory effect as a dose-dependent manner, from 1.25 mg/kg to 12.5 mg/kg, in acute inflammatory models (carrageen and egg-albumin induced rat hind paw edema). It also elicited significant anti-inflammatory activity in chronic inflammatory models (cotton pellet granuloma and Freund's adjuvant induced polyarthritis in rat). In cotton pellet granuloma test, the extract exhibited the inhibitory effect of 23 and 57% at the dose of 6.25 and 12.5 mg/kg, respectively. In Freund's adjuvant induced model, the treatment of the extract of 1.25, 6.25 and 12.5 mg/kg showed the inhibitory effect of 23, 56 and 66% at 8 days, respectively. In the acetic acid-induced model, the extract significantly reduced abdominal writhing in mice when compared to the control group, reducing the mean number of writhing from $41{\pm}2$ in the control group to $17{\pm}3$ and $15{\pm}2$ at the dose of 6.25 and 12.5 mg/kg. From these experiments, the extract, which was extracted from the combination of Bacopa monnieriis, Cassia fistula and Phyllanthus polyphyllus, (w/w/w = 1/2/1) is surprisingly found a significant analgesic and anti-inflammatory activity.

  • Inflammation is an immune response that protects against pathogens and cellular stress. The hallmark of inflammatory responses is inflammasome activation in response to various stimuli. This subsequently activates downstream effectors, that is, inflammatory caspases such as caspase-1, 4, 5, 11, and 12. Extensive efforts have been made on developing effective and safe anti-inflammatory therapeutics, and ginseng has long been traditionally used as efficacious and safe herbal medicine in treating various inflammatory and inflammation-mediated diseases. Many studies have successfully shown that ginseng plays an anti-inflammatory role by inhibiting inflammasomes and inflammasome-activated inflammatory caspases. This review discusses the regulatory roles of ginseng on inflammatory caspases in inflammatory responses and also suggests new research areas on the anti-inflammatory function of ginseng, which provides a novel insight into the development of ginseng as an effective and safe anti-inflammatory herbal medicine.

  • In an attempt to elucidate the anti-inflammatory action of ginseng total saponin, protopanaxadiol and protopanaxatriol, the anti-inflammatory activity of three compounds was investigated under various acute and chronic inflammatory models. The blood vessel permeability was slightly inhibited by total saponin and protopanaxatriol treatments. Granuloma formation induced by 2% carrageenan was inhibited by total saponin and protopanaxatriol. The cotton-pellet granuloma formation was significantly inhibited by intraperitoneal injection of total saponin. Total saponin and protopanaxadiol inhibited leukocyte emigration and protein exudation in CMC-induced pouch but protopanaxauiol increased leukocyte emigration. The swelling of rat hind paw induced by 1% carrageenan was significantly inhibited by total saponin, protopanaxadiol and protopanaxatriol both single and 2 weeks treatments. Total saponin, protopanaxadiol and protopanaxatriol decreased the anti-inflammatory activity in adrenalectomized rat. Our results suggest that total saponin, protopanaxadiol and protopanaxatriol have potent anti-inflammatory activity, this may be mediated in part through stimulation of adrenal glands.

  • The fruit of the black raspberry (Rubus coreanus Miquel) has been employed in traditional medicine, and recent studies have demonstrated its measureable biological activities. However, the root of the black raspberry has not been studied. Therefore, in this study, we evaluated the anti-inflammatory and antibacterial properties of the root and unripe fruit polyphenols of the black raspberry. Both polyphenols proved to have anti-inflammatory activity as evidenced by the decreased nitric oxide (NO), cytokines (IL-$1{\beta}$, IL-6, and IL-10) and prostaglandin E2 ($PGE_2$) levels in lipopolysaccharide (LPS)-stimulated RAW 264.7 murine macrophages. However, root polyphenols showed stronger anti-inflammatory activity than fruit polyphenols. LPS-induced mRNA and protein expressions of inducible NO synthase (iNOS) and cyclooxygenase (COX)-2 levels were also decreased, confirming the anti-inflammatory activity. Root polyphenols showed lethal activity against methicillin-resistant Staphy-lococcus aureus (MRSA), carbapenem-resistant Acinetobacter baumannii (CRAB), and Bacillus anthracis. In contrast, the black raspberry fruit did not demonstrate these properties. These data provide the first demonstration that black raspberry root has potential anti-inflammatory and anti-superbacterial properties that can be exploited as alternatives for use in the food and cosmetic industries and/or as pharmaceuticals.

  • Soy sauce is one of the representatives of traditional fermented foods in Korea. However, studies on soy sauce are relatively insufficient in Korea compared to Japan. In this study, antioxidant and anti-inflammatory activities of polysaccharides were measured by polysaccharides isolated from two different soy sauces, Korean and Japanese (KSS-0 and JSS-0). KSS-0 was purified into two fractions using gel chromatography and named them as KSS-I and KSS-II. To investigate the antioxidant activity of the polysaccharides, we measured the polyphenol content and radical scavenging activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). To investigate the anti-inflammatory activity of polysaccharides, we used RAW 264.7 macrophage cells and induced inflammation using lipopolysaccharide (LPS). Then, we measured levels of inflammatory mediators such as nitric oxide (NO) and tumor necrosis factor (TNF)-α. Among the four polysaccharides, KSS-II showed the highest antioxidant activity and had good anti-inflammatory activity; KSS-II decreased inflammatory mediators in a dose-dependent manner. In conclusion, the polysaccharide isolated from Korean soy sauce (KSS-II) showed better anti-oxidant and anti-inflammatory activities than polysaccharides isolated from Japanese soy sauce, and may be useful as substances for functional foods.

  • In Northeast Asia, Paeoniae Radix has been used in treatments of inflammation-causing diseases such as arthritis for many centuries. Paeoniflorin, one of the principle bioactive monoterpene glucosides from the paeony root, is reported to be mostly responsible for the effectiveness of the treatments. However, the anti-inflammatory effect of a monoterpene, paeoniflorigenone (PFG) which partially has the moiety of paeoniflorin minus a glucose structure is unknown. Thus, the aim of this work was to investigate anti-inflammatory activity of PFG. For the investigation, PFG activity on the NO (nitric oxide) production from LPS-stimulated macrophages, and the anti-inflammatory effect was tested in the animal model of septic arthritis caused by Candida albicans, a major etiological agent for septic arthritis. For induction of the arthritis, mice were administered with an emulsion of C. albicans cell wall (CACW) mixed with Complete Freund's Adjuvant (CFA) via footpad-injection (Day 0); PFG at a dose of 0.5 or 1 mg/mouse (25 or 50 mg/kg of body-weight) was given to the animals on Day 3, 6, and 9; footpads were scored for arthritis. Moreover, the PFG effect on proliferation of T-lymphocyte that causes aggravation of arthritis was additionally tested. Data resulting from those tests showed that PFG inhibited the NO production from the stimulated macrophage in a dose dependent manner (P<0.05), indicating that PFG is an anti-inflammatory. To confirm the in-vitro results, anti-inflammatory activity of PFG was determined against C. albicans-caused septic arthritis. Data showed that PFG-treatment reduced footpad-swelling which indicates that PFG has anti-arthritic effect (P<0.05), which is therapeutic. The anti-arthritic effect appeared to be mediated by PFG suppression of T-cell proliferation. Ultimately, PFG, a monoterpene component, has anti-inflammatory activity analogous to paeoniflorin. The anti-inflammatory activity treats the septic arthritis due to a pathogenic fungus C. albicans.
