breynia officinalis/glycoside

From the leaves of Breynia officinalis, collected on Okinawa Island, six terpenic glucosides and six phenolic glycosides were isolated. Two of the terpenic glucosides were found to be known, and they were identified as turpinionoside B and betulalbuside A. The structures of the remaining terpenic

Glycosides, 3-acetyl-(-)-epicatechin 7-O-beta-glucopyranoside (1), 3-acetyl-(-)-epicatechin 7-O-(6-isobutanoyloxyl)-beta-glucopyranoside (2), 3-acetyl-(-)-epicatechin 7-O-[6-(2-methyl-butanoyloxyl)]-beta-glucopyranoside (3),

A new sulfur-containing spiroketal glycoside, breynin I (1), and a new terpenic glycoside, breyniaionoside E (2), together with 10 known compounds, were isolated from the aerial parts of Breynia vitis-idaea (Euphorbiaceae), a traditional Chinese medicine used for the treatment of chronic bronchitis

Phytochemical investigation of the chemical constituents of the aerial parts of Breynia fruticosa afforded 10 sulfur-containing spiroketal glycosides, including eight new compounds (1-8) and two known compounds, epibreynin B (9) and breynin B (10). Epibreynin B (9) was previously reported as a

OBJECTIVE To study the chemical constituents of Breynia rostrata Merr. METHODS Chromatography was used to isolate and purify the chemical constituents, their structures were identified by spectral analysis. RESULTS Four glycosides were identified as 6-O-methylpropanoyl-alpha-D-glucopyranoside (1),

A simple, green method is described for the synthesis of Gold (Au) and Silver (Ag) nanoparticles (NPs) from the stem extract of Breynia rhamnoides. Unlike other biological methods for NP synthesis, the uniqueness of our method lies in its fast synthesis rates (~7 min for AuNPs) and the ability to
