Astragalus ernestii has been used as a substitute for Radix Astragali (Huang-Qi) in southwest China. To better understand the chem. rationale for the medicinal usage, the phytochem. of A. ernestii was recently studied. As a result, a novel aurone-phenylpropanoid adduct astrernestin (1), together with five known phenoloids calycosin-7-O-β-D-glucopyranoside (2), 4,4′-dimethoxy-3′-hydroxy-7,9′:7′,9-diepoxylignan-3-O-β-D-glucopyranoside (3), syringaresinol-4-O-β-D-monoglucoside (4), hedyotol D 4”-O-β-D-glucopyranoside (5) and trifolirhizin (6), were isolated from the roots of A. ernestii. The structure of compound was elucidated by extensive spectroscopic anal. and optical rotation calculation In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-2-(((6aR,12aR)-6a,12a-Dihydro-6H-[1,3]dioxolo[4′,5′:5,6]benzofuro[3,2-c]chromen-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 6807-83-6Electric Literature of C22H22O10).

Trifolium pratense, a widespread legume forage plant, is reported to exhibit phytotoxic activity on other plants, but the active metabolites have not been clarified so far. A bioassay-guided fractionation of the root extracts led to the isolation of five isoflavonoids, which were elucidated by spectroscopic anal. All of the purified compounds observably showed phytotoxic activities against Arabidopsis thaliana. Moreover, the inhibitory effects were concentration-dependent. The furan ring linked at C-4 and C-2′ positions by an oxygen atom and a 1,3-dioxolane at C-4′ and C-5′ positions are considered to be critical factors for the phytotoxic activity. The concentrations of (6aR,11aR)-maackiain and (6aR,11aR)-trifolirhizin, concluded to be allelochems. from soil around plants of T. pratense, were determined by HPLC and LC-MS to be 4.12 and 2.37 μg/g, resp. These allelochems., which showed remarkable activities against the weed Poa annua may play an important role in assisting the widespread occurrence of T. pratense in nature.

In this study, a high performance liquid chromatog. coupled with multi-stage mass spectrometry method (HPLC-MS) was developed for simultaneous characterization of alkaloids and flavonoids, the main active components, in Kushen with diverse phys. and chem. properties. Forty-two major constituents, including sixteen Kushen alkaloids and twenty-six Kushen flavonoids were tentatively identified. Addnl., useful and characteristic fragmentation pathways of two types of Kushen alkaloids, namely cytisine-type and sparteine-type, in pos. ions mode were proposed and summarized, which would lay a foundation for the rapid identification of the active ingredients in traditional Chinese medicine Kushen. In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-2-(((6aR,12aR)-6a,12a-Dihydro-6H-[1,3]dioxolo[4′,5′:5,6]benzofuro[3,2-c]chromen-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 6807-83-6Reference of 6807-83-6).

And the article was included in Tropical Journal of Pharmaceutical Research in 2020.Quality Control of (2S,3R,4S,5S,6R)-2-(((6aR,12aR)-6a,12a-Dihydro-6H-[1,3]dioxolo[4′,5′:5,6]benzofuro[3,2-c]chromen-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol This article mentions the following:

To investigate the effect of trifolirhizin on neonatal rat model of asthma, and the mechanism of action involved. Neonatal rats (n = 50) were randomly assigned to 5 groups (10 pups/group): sham, asthma and three treatment groups. With the exception of sham group, the rat pups were sensitized i.p. with ovalbumin (OVA) at a dose of 20μg/kg on days 7 and 21 postpartum. Rats in the treatment groups received trifolirhizin intragastrically at doses of 2, 4 and 5 mg/kg on day 7 postpartum. Eosinophils in bronchoalveolar lavage fluid (BALF) were counted using hematol. analyzer. Serum Ig (Ig)E and interleukin (IL)-4, IL-5 and IL-13 levels in BALF were determined using their resp. ELISA (ELISA) kits. MRNA (mRNA) expressions of mucin 5AC (Muc5AC), mucin 5B (Muc5B), tumor necrosis factor α (TNF-α) and intercellular adhesion mol.-1 (ICAM-1) were determined using immunohistochem. staining, while the protein expression of inhibitor of nuclear factor of kappa light polypeptide gene enhancer in B-cells alpha (IκBα) was assayed by Western blotting. Serum IgE level was significantly higher in asthma group than in sham group, but was significantly and dose-dependently reduced after treatment with trifolirhizin (p < 0.05). Lung tissue damage was also significantly mitigated in the treatment groups, relative to asthma group (p < 0.05). Trifolirhizin treatment significantly and dose-dependently downregulated the mRNA expressions of Muc5AC, Muc5B, TNF-α and ICAM-1, but upregulated IκBα protein expression significantly and dose-dependently (p < 0.05). Bronchoalveolar lavage fluid (BALF) levels of IL-4, IL-5 and IL-13 were significantly higher in asthma group, but were significantly and dose-dependently reduced after treatment with trifolirhizin (p < 0.05). Conclusion: These results indicate that trifolirhizin mitigates OVA-induced lung inflammation and tissue damage in neonatal rats via inhibition of NF-κB signaling pathway, thus affording a potential therapeutic strategy for the management of asthma.
