Steroidal Constituents from Roots and Rhizomes of Smilacina japonica.

ABSTRACT: Four new steroidal constituents (1-4) along with two known steroidal glycosides (5 and 6) were isolated from the roots and rhizomes of Smilacina japonica. Analysis of their physicochemical properties and spectroscopic profiles identified the compounds as (25S)-5?-spirostan-9(11)-en-3?, 17?-diol (1); (25S)-5?-spirostan-9(11)-en-3?, 12?-diol (2); (25S)-5?-spirostan-9(11)-en-3?, 17?-diol-3-O-?-d-glucopyranoside (3); (25S)-5?-spirostan-9(11)-en-3?, 17?-diol-3-O-?-d-glucopyranosyl-(1?2)-[?-d-glucopyranosyl-(1?3)]-?-d-galactopyranoside (4); japonicoside B (5); and japonicoside C (6). All six compounds showed cytotoxic activity against SMMC-7712, Bel-7402, A549, H460, and K562 human cancer cells.

Chemical Constituents from the Roots and Rhizomes of Asarum heterotropoides var. mandshuricum and the In Vitro Anti-Inflammatory Activity.

Project description:Anti-inflammatory compounds were investigated from the ethanol extract of the roots and rhizomes of Asarum heterotropoides var. mandshuricum, a traditional Chinese medicine called Xixin and used for pain and inflammatory. Nine new compounds were isolated, including six new lignans, neoasarinin A-C (1-3), neoasarininoside A and B (4 and 5), and asarinin B (7), and one new monoterpene, asarincin A (8), two new amides, asaramid II and III (10 and 11), and one new natural monoterpene, asaricin B (9), along with 37 known compounds (6, 12-47). Their structures and absolute configurations were elucidated on the basis of spectroscopic methods and chemical analyses. This is the first report of the absolute configuration of asarinin A (6). The 8-O-4' neolignans (1-5) were reported in the genus Asarum for the first time. The 15 compounds 17, 19, 22-25, 28, 31, 36, 40, 42, 43, 45-47 were isolated from the genus Asarum, and compounds 16, 32, 33, 37 and 39 were isolated from A. heterotropoides var. mandshuricum for the first time. Thirty-seven of the isolates were evaluated for anti-inflammatory activity against the release of ?-glucuronidase in polymorphonuclear leukocytes (PMNs) induced by the platelet-activating factor (PAF), and compounds 1, 4, 7, 8, 14, 17-19, 22, 24, 25, 29, 30, 32, 33, 40-43, 45, and 46 showed potent anti-inflammatory activities in vitro, with 27.9%-72.6% inhibitions at 10-5 mol/L. The results of anti-inflammatory assay suggested that lignans obtained from the CHCl? extract might be the main active components of Xixin.

Phytochemical analysis of Canna indica L. roots and rhizomes extract.

Project description:Canna indica L. (Cannaceae) roots and rhizomes were reported to possess various biological properties like antimicrobial, anthelmintic potential and HIV-1 reverse transcriptase inhibition. In our previous studies, they showed antidiabetic activity on normal rats and rats co-addicted with caffeine and nicotine. In the pursuit of the phytochemical/s responsible for these biological activities, present study was aimed at phytochemical evaluation of hydroalcoholic extract (HAE) of C. indica L. roots and rhizomes; including preliminary screening, thin layer chromatography, H1-NMR and HR-LC/MS-MS analysis. After preliminary detection of flavonoids, tannins and sterols, HAE was tested for presence of ?-sitosterol using TLC. H1-NMR spectrum of HAE revealed the presence of around 761 deshielded protons corresponding to different polar compounds. HR-LC/MS-MS analysis carried out at both positive and negative ion mode, indicated the presence of more than 90 compounds including short fragment of peptide. As per METLIN database, predicted major phytochemicals were 3'-hydroxytrimethoprim, 3,7-epoxycaryophyllan-6-one, swietenine, typhasterol, hexacosanedioic acid and 3?, 6?,7?-trihydroxy-5?-cholan-24-oic acid few of which, are biologically active.

New Steroidal Saponins from the Rhizomes of Paris vietnamensis and Their Cytotoxicity.

Project description:Four new spirostanol saponins, named pavitnosides A-D (1-4), with six known steroidal saponins 5-10 were isolated from the rhizomes of Paris vietnamensis. Their chemical structures were determined based on extensive spectroscopic studies and chemical methods. The aglycones of pavitnoside B and pavitnoside C were not reported in previous work. The cytotoxicity of all saponins was evaluated against human glioblastoma U87MG and U251 cell lines. The new spirostanol saponin 1 displayed weak anti-proliferative activity against U87MG cell line and the known saponins 8 and 9 exhibited significant cytotoxicity against the two tumor cell lines, with IC50 values of 2.16 to 3.14 ?M, but did not affect the growth of primary cultures of human astrocytes.

Chemical constituents from the rhizomes of Smilax glabra and their antimicrobial activity.

Project description:Six new phenolic compounds, named smiglabrone A (1), smiglabrone B (2), smilachromanone (3), smiglastilbene (4), smiglactone (5), smiglabrol (6), together with fifty-seven known ones 7-63 were isolated from the rhizomes of Smilax glabra. Their structures were elucidated on the basis of extensive spectroscopic analyses, as well as by comparison with literature data. Twenty-seven of these compounds were obtained from and identified in the genus Smilax for the first time. The absolute configuration of (2S)-1,2-O-di-trans-p-coumaroylglycerol (43) was determined for the first time using the exciton-coupled circular dichroism (ECCD) method. Thirty isolated compounds were evaluated for their antimicrobial activity against three Gram-negative bacteria, three Gram-positive bacteria and one fungus, and the corresponding structure-activity relationships were also discussed. Eighteen compounds were found to be antimicrobial against the microorganisms tested and the minimum inhibitory concentrations (MIC) were in the range of 0.0794-3.09 mM. Among them, compound 1 showed antimicrobial activity against Canidia albicans with MIC value of 0.146 mM, which was stronger than cinchonain Ia with an MIC of 0.332 mM. Compounds 3 and 4 exhibited inhibitory activity against Staphylococcus aureus with MIC values of 0.303 and 0.205 mM, respectively. The results indicated that these antimicrobial constituents of this crude drug might be responsible for its clinical antimicrobial effect.

Identification of Nematicidal Constituents of Notopterygium incisum Rhizomes against Bursaphelenchus xylophilus and Meloidogyne incognita.

Project description:During a screening program for new agrochemicals from Chinese medicinal herbs, the ethanol extract of Notopterygium incisum rhizomes was found to possess strong nematicidal activity against the two species of nematodes, Bursaphelenchus xylophilus and Meloidogyne incognita. Based on bioactivity-guided fractionation, the four constituents were isolated from the ethanol extract and identified as columbianetin, falcarindiol, falcarinol, and isoimperatorin. Among the four isolated constituents, two acetylenic compounds, falcarindiol and falcarinol (2.20-12.60 ?g/mL and 1.06-4.96 ?g/mL, respectively) exhibited stronger nematicidal activity than two furanocoumarins, columbianetin, and isoimperatorin (21.83-103.44 ?g/mL and 17.21-30.91 ?g/mL, respectively) against the two species of nematodes, B. xylophilus and M. incognita. The four isolated constituents also displayed phototoxic activity against the nematodes. The results indicate that the ethanol extract of N. incisum and its four isolated constituents have potential for development into natural nematicides for control of plant-parasitic nematodes.
