Phytochemical investigation of 80% MeOH extract of the aerial parts of Capsella bursa-pastoris yielded fourteen compounds (1 – 14). The structures of the compounds were elucidated by spectroscopic methods to be methyl-1-thio-β-D-glucopyranosyl disulfide (1), 10-methylsulphinyl-decanenitrile (2), 11-methyl-sulphinyl-undecanenitrile (3), 1-O-(lauroyl)glycerol (4), phytene-1, 2-diol (5), (3S,5R,6S,7E)-5,6-epoxy-3-hydroxy-7-megastigmen-9-one (6), loliolide (7), β-sitosterol (8), 3-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-1-propanone (9), 1-feruloyl-β-D-glucopyranoside (10), pinoresinol-4′-O-β-D-glucopyranoside (11), luteolin (12), quercetin-3-O-β-D-glucopyranoside (13), and luteolin 6-C-β-glucopyranoside (14). Although compound 1 was reported as synthetic compound, 1 was first isolated from natural source. NMR spectral data assignments of 1, 2 and 3 were reported for the first time, and compounds 1 – 14 were for the first time reported from this plant source. The anti-inflammatory effects of 1 – 14 were evaluated in lipopolysaccharide (LPS)-stimulated murine microglia BV-2 cells. Compounds 12 exhibited strong inhibitory effects on nitric oxide production in LPS-activated BV-2 cells with IC50 values of 9.70 µM.

Water extracts of six plants, such as Allium sativum, A. cepa, Zingiber officinale, Platycodon grandiflorum, Oenanthe javanica, and Capsella brusapastoris, were tested in vitro for inhibitory activity against mycelial growth of anthracnose fungi, Colletotrichum gloeosporioides, C. dematium, and C. coccodes. Among the plant extracts, an Allium sativum extract has good inhibitory effects in all the fungi. Four phytohormones namely, IAA (indole-3-acetic acid), NAA (a-Naphthyl acetic acid), 2,4-D (2,4-Dichloro phenoxy acetic acid) and BAP (Benzyl adenine purine) were used to find out the role over mycelial growth of these fungi. All the concentrations of BAP have good inhibitory effect against mycelial growth of these fungi than that of other tested plant hormones.

Shepherd's purse, Capsella bursa-pastoris (L.) Medik., has been considered a health food for centuries in Asia and is known to contain the isothiocyanate compound sulforaphane. In this study, we evaluated the anti-inflammatory and antibacterial properties of a sulforaphane-containing solution (SCS) isolated from shepherd's purse. SCS had significant anti-inflammatory activity indicated by the decreased levels of nitric oxide (NO), cytokines (interleukin 1beta [IL-1beta], IL-6, and IL-10), and prostaglandin E2 (PGE2) in lipopolysaccharide-stimulated RAW 264.7 murine macrophages. In addition, SCS decreased the inducible NO synthase (iNOS) and cyclooxygenase 2 (COX-2) levels, which confirmed the anti-inflammatory activity of SCS. Further, SCS inhibited vancomycin-resistant enterococci (VRE) and Bacillus anthracis. The minimal inhibitory concentration was 250 microg/ml for VRE and 1,000 microg/ml for B. anthracis. Taken together, these data indicate that SCS has potential anti-inflammatory and anti-superbacterial properties, and thus it can be used as a functional food or pharmaceutical.
