Cytotoxic germacranolide sesquiterpene from Inula cappa.
Xie HG, Chen H, Cao B, Zhang HW, Zou ZM.
Abstract
A new germacranolide, inulacappolide (1), was isolated from the EtOH extract of the whole plant of Inula cappa along with 16 known compounds. The structure of inulacappolide was a rare 1(10)-saturated type of germacran-6,12-olide, identified as 2alpha-acetoxy-3beta-hydroxy-9beta-angeloyloxygermacra-4-en-6alpha,12-olide by spectral analysis (IR, HR-ESI/MS, (1)H-NMR, (13)C-NMR, HMQC, HMBC, NOESY). In vitro, it showed antiproliferative effects against human cervical cancer HeLa, human leukemia K562 and human nasopharyngeal carcinoma KB cell lines with IC(50) values of 1.2 microM, 3.8 microM and 5.3 microM, respectively.

Anti-inflammatory and immunomodulatory activities of Inula cappa roots (Compositae).

Abstract
Background The medicinal properties of Inula cappa, a perennial shrub, are ascribed to its roots. In this article, we study the anti-inflammatory and immunomodulatory activities of I. cappa root extracts based on its utilization in traditional medicine-treatment of rheumatoid arthritis, menoxenia, fever, jaundice and many others. Methods Anti-inflammatory and immunomodulatory activities of I. cappa extracts were studied. The anti-inflammatory activity was determined by carrageenan-induced rat paw edema and cotton pellet-induced granulation method while the immunomodulatory activity was estimated by phagocytic assay method, hemagglutinating antibody (HA) titer assay, delayed-type hypersensitivity assay method, plaque forming cell assay and determination of immunoprophylatic activity. Results The methanolic extract showed maximum reduction in the rat paw edema and showed significant inhibition of the cotton pellet-induced granulomas in rats. The methanolic extract also showed potential immunomodulatory activity in all the assays performed. Two sesquiterpenes, isoalantolactone and germacranolide were also isolated from the methanolic extract. Conclusions The present study supports the evidence that the roots of I. cappa can be used as a potent anti-inflammatory and immunomodulatory agent.

Anti-inflammatory Inositol Derivatives from the Whole Plant of Inula cappa.
Wu J, Tang C, Yao S, Zhang L, Ke C, Feng L, Lin G, Ye Y.
Abstract
Twelve new inositol derivatives, classified into myoinositol (1-6) and l-inositol (10-15) types, along with five known analogues were isolated from the whole plant of Inula cappa. The structures of the new compounds were established by extensive analysis of mass spectrometric and 1D and 2D NMR spectroscopic data. All the tested compounds showed anti-inflammatory activities against the production of NO in RAW264.7 macrophages stimulated by lipopolysaccharide, with IC50 values ranging from 7 to 23 μM.
