[PMID: 37487918 DOI: 10.1016/j.phytochem.2023.113795] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 06/28/2023] [Accepted: 07/19/2023] [Indexed: 07/26/2023]
Abstract
Herein, five undescribed oleanane-type triterpenoid saponins, namely, psammosaponins A-E, along with nine known compounds, were isolated from the roots of Psammosilene tunicoides. Moreover, part of the ethanolic extract of P. tunicoides was acid-hydrolyzed and three aglycones were isolated from the resulting hydrolysate. The structures of all compounds were established through extensive analysis involving 1D and 2D NMR experiments, HRESIMS measurements, chemical derivatization, and comparison of spectroscopic data with the values reported in the literature. In all, 10 of the isolated saponins and the three aglycones were evaluated in the acetic acid-induced writhing model for their antinociceptive activity. At a dose of 40 mg/kg, these compounds exhibited significant inhibitory effects on the mouse writhing response, with inhibitions ranging from 31.9% to 79.3%. In addition, the structure-activity relationships of the isolates were discussed. Among the isolates, quillaic acid 3-O-glucuronide and 16α-hydroxygypsogenic acid showed better antinociceptive activity with inhibitions of 79.3% and 73.7%, respectively. Both isolates also exhibited antinociceptive activities in hot plate and formalin tests on mice. Their antinociceptive mechanism was explored in lipopolysaccharide-stimulated RAW 264.7 cells. These isolates could significantly inhibit the production of nitric oxide and interleukin-6 and downregulate the expression levels of inducible NO synthase, COX-1, and COX-2.

Szewczyk K, Bonikowski R, Maciąg-Krajewska A, Abramek J, Bogucka-Kocka A. Lipophilic components and evaluation of the cytotoxic and antioxidant activities of Impatiens glandulifera Royle and Impatiens noli – tangere L. (Balsaminaceae). GRASAS Y ACEITES 2018.

Abstract
The chemical composition of the lipophilic fractions of Impatiens glandulifera Royle and I. noli-tangere L. were analyzed by gas chromatography-mass spectrometry (GC-MS)., The study focused on the fatty acids, triterpenoids and sterols in the leaves, roots and seeds. Most of the identified compounds are new for these species. a-linolenic, oleic and palmitic acids were the most abundant in the fatty acid fractions, β-amyrin and 5a-lup-20(29)-en-3β-ol in the triterpenoid fractions, and β-sitosterol, spinasterol and chondrillasterol in the sterol fractions. The fatty acid and triterpenoid fractions showed strong antioxidant activity, similar to positive controls. Moreover, the triterpenoid fraction from I. noli-tangere seeds significantly inhibited HL-60 human leukemia cells. Other fractions showed moderate cytotoxicity. The present study suggests that I. glandulifera and I. noli-tangere are good source of omega-3 fatty acids, and they might be considered as antioxidant and chemopreventive agents.

Abstract
The present paper describes the chemical composition of the essential oils obtained by hydrodistillation from four Impatiens species, Impatiens glandulifera Royle, I. parviflora DC., I. balsamina L. and I. noli-tangere L. The GC and GC-MS methods resulted in identification of 226 volatile compounds comprising from 61.7%-88.2% of the total amount. The essential oils differed significantly in their composition. Fifteen compounds were shared among the essential oils of all investigated Impatiens species. The majority of these constituents was linalool (0.7%-15.1%), hexanal (0.2%-5.3%) and benzaldehyde (0.1%-10.2%). Moreover, the antioxidant activity of the essential oils was investigated using different methods. The chemical composition of the essential oils and its antioxidant evaluation are reported for the first time from the investigated taxon.

JOURNAL OF ETHNOPHARMACOLOGY 2015; 162:163-167. [PMID: 25543019 DOI: 10.1016/j.jep.2014.12.024] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/02/2014] [Revised: 12/07/2014] [Accepted: 12/16/2014] [Indexed: 06/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Many different tribes of American Indians used jewelweed, Impatiens capensis Meerb, as a plant mash to reduce development of poison ivy dermatitis. Saponins are a natural soapy constituent found within plants. A 2012 study suggested that saponins may be present in jewelweed which could be responsible for its efficacy in preventing rash development following contact with Toxicodendron radicans (L.) Kuntze (poison ivy). This study validated this hypothesis and demonstrated additional biological activity of the jewelweed saponin containing extract. MATERIALS AND METHODS Fresh I. capensis leaves were extracted with methanol and further partitioned between ethyl acetate and water, with a final separation between water and n-butanol, to obtain a saponin containing extract. The presence of saponins in the extract was demonstrated by the observation of foaming and using a vanillin colorimetric assay for total saponins. Efficacy of the saponin containing extracts in rash reduction was tested by brushing poison ivy (PI) onto the forearms of volunteers (N=23) in six locations and treating these PI exposed areas with distilled water (control), saponin containing extracts, fresh plant mashes, and soaps made with and without plant extracts. Saponin containing extracts were further tested for biological activity against both gram negative and gram positive bacteria and against cancer cell lines A-375, HT-29, and MCF-7. Additionally, because saponins have been shown to have a stimulatory effect in cardiac muscle 2 µl saponin extract was applied superficially to black worms, Lumbriculus variegatus (N=5). RESULTS, AND CONCLUSIONS Both saponin containing extracts and all soaps tested were effective in reducing poison ivy dermatitis; thus, saponin content correlates with PI rash prevention. No apparent antibiosis was observed against any bacteria tested; however, dose response cytotoxicity was documented against MCF-7 breast cancer cells and cytostatic activity was seen against the HT-29 colon cancer cell lines. Lumbriculus variegatus exhibited a 138% increase in heart rate over baseline rate five minutes post treatment implying a possible positive chronotropic effect.

Abstract
An isomeric mixture of two cerebrosides, soya-cerebrosides I and II, was isolated from an ethno drug, the rhizomes of Impatiens pritzellii Hook. f. var. hupehensis Hook. f., and their structures were identified by spectroscopic (NMR, MS) analysis. In order to determine the immunomodulatory activities of soya-cerebrosides I and II, the effects of the mixture of cerebrosides (MC) on cytotoxicity of human peripheral blood mononuclear cells (PBMC) and the inhibitory activities to lipopolysaccharide (LPS)-induced interleukin (IL)-18 in PBMC were studied. The MC at concentrations of 10 and 1 microM, without toxicity to PBMC in 24 h, showed obvious inhibitory activity on IL-18 secretion. Because of this effect of modulating the cellular immune response, soya-cerebrosides I and II were considered to be the active substances of this ethno drug.

Abstract
Triterpenoid saponins, impatienosides A-G, together with 12 known saponins, were isolated from the whole plants of Impatiens siculifer. Their structures were established on the basis of extensive 1D and 2D NMR and MS analyses coupled with chemical degradation. Cytotoxic activities of the isolated saponins were evaluated against three human cancer cell lines: human myeloid leukemia HL-60 cells, human stomach KATO-III adenocarcinoma, and human lung A549 adenocarcinoma.
