ABSTRACT Radix Angelica Sinensis, the dried root of Angelica sinensis (Danggui), is a herb used in Chinese medicine to enrich blood, promote blood circulation and modulate the immune system. It is also used to treat chronic constipation of the elderly and debilitated as well as menstrual disorders. Research has demonstrated that Danggui and its active ingredients, as anti-arthrosclerotic, anti-hypertensive, antioxidant anti-inflammatory agents which would limit platelet aggregation, are effective in reducing the size of cerebral infarction and improving neurological deficit scores.

    ABSTRACT: The root of Angelica sinensis (Oliv.) Diels (abbreviated as AS) (Danggui) has a long history in Asian herbal medicine. Recently, it was demonstrated that AS possesses anti-cancer and anti-oxidant activities. Because the transcription factor Nrf2 mediates the expression of many cellular anti-oxidative stress genes, including genes that are involved in phase II drug metabolism and anti-oxidative stress, this study sought to investigate whether pure compounds from AS or an AS extract could activate antioxidant response element (ARE)-mediated gene expression and induce anti-inflammatory activities. Z-Ligustilide (Ligu), 3-butylidenephthalide (Buty) and CO2 supercritical fluid-extracted lipophilic AS extract (SFE) were tested in HepG2-C8 cells stabilized with ARE luciferase reporter gene. Ligu and Buty caused significant toxicity only at 100 μM. All three of the samples induced ARE-luciferase activity; however, SFE at 8.5 µg/mL induced ARE-luciferase activity 2-3 fold more potently than did either of the pure compounds. SFE also significantly increased the endogenous mRNA of Nrf2 and the Nrf2 target anti-oxidative gene NAD(P)H dehydrogenase, quinone 1 (NQO1). The protein expression of NQO1 was also significantly induced by SFE. In RAW 264.7 cells, SFE suppressed LPS-induced IL-1β and TNF-α expression about 2 fold stronger than sulforaphane, whereas both the pure compounds and SFE suppressed inflammatory nitric oxide (NO) production. In summary, our study demonstrates that AS has anti-inflammatory effects and activates the Nrf2 pathway, which protects against oxidative stress. This article is protected by copyright.

    ABSTRACT: The present study was performed to investigate the effects of Jin-Ying-Tang (JYT), a Chinese herbal formula containing Lonicera japonica, Herba taraxaci, Fructus trichosanthis, Fructus forsythia, Radix et rhizoma rhei, Astragalus membranaceus, Angelica sinensis, on rabbit mastitis induced by Staphylococcus aureus. Suckling rabbits were challenged with 1.5 × 10(7) colony forming unit (CFU) of S. aureus at the base of the third pair teats, and they were treated and pretreated with JYT to detect the formula effects. The results showed that JYT could reduce the occurrence of Staphylococcal mastitis in rabbit model. To further investigate the action mechanism of JYT, we examined the leukocyte counts and inflammatory mediator levels such as TNF-α and IL-6 in blood and infected tissue. From histological study and blood analysis, we found that JYT could suppress leukocyte infiltration in infected mammary gland tissue and significantly inhibit the total leukocyte counts and lymphocytes (LYM), monocytes (MON) and granulocytes (GRA) fractions of leukocyte counts in blood. Enzyme-linked immunosorbent assay (ELISA) results showed JYT significantly decreased the TNF-α and IL-6 concentrations in serum and mammary gland. The analysis of these data suggested that JYT effectively inhibited inflammatory responses to reduce the occurrence of mastitis in rabbit model.
