Functional activities of three Rehmannia glutinosa enzymes: Elucidation of the Rehmannia glutinosa salidroside biosynthesis pathway in Saccharomyces cerevisiae

Gene
Rehmannia glutinosa produces many phenylethanoid glycoside (PhG) compounds, including salidroside, which not only possesses various biological activities but also is a core precursor of some medicinal PhGs, so it is very important to elucidate the species' salidroside biosynthesis pathway to enhance the production of salidroside and its derivations ...

Five cyclopentanoid monoterpenes from Rehmannia glutinosa

Phytochemistry, 1989
Abstract Five new cyclopentanoid monoterpenes named jioglutins A, B, C, jioglutolide and jiofuran, along with other known compounds, have been isolated from the steamed roots of Rehmannia glutinosa var. hueichingensis and their structures elucidated on the basis of chemical and spectroscopic methods.

[Study on the HPCE fingerprint of Rehmannia glutinosa].

Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2013
To establish the analytical method for the fingerprint of Rehmannia glutinosa by HPCE and compare the fingerprints of Rehmannia glutinosa and its processed products.Based on the mode of high performance capillary electrophoresis, 60 mmol/L sodium borate was used as buffer solution (5% MeOH, pH 9.5).

[Preservation of germplasm of Rehmannia glutinosa in vitro].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2004
To establish a method for the germplasm preservation of R. glutinosa.Plantlets of different cultivars obtained by tip culture were inoculated into test tubes with MS medium supplemented with 0.2 mg.L-1 BA and 0.02 mg.L-1 NAA, and preserved at 4-6 degrees C in dark. At the same time, different media (A. distilled water + 10 g.L-1 agar; B. 1/2 MS + 5 g.L-

Norcarotenoid glycosides of Rehmannia glutinosa var. Purpurea

Phytochemistry, 1991
Abstract Three new norcarotenoid glycosides named jiocarotenosides A1, A2 and 6-O-sec-hydroxyaeginetoyl ajugol, together with two known compounds, have been isolated from the dried roots of Rehmannia glutinosa var. purpurea. Their structures were determined by chemical and spectral studies, and confirmed by X-ray analysis of jiocarotenoside A1.

Two iridoid glycosides from Rehmannia glutinosa

Phytochemistry, 1989
Two new iridoid glycosides named jioglutosides A and B, together with 11 known iridoid glycosides, have been isolated from the fresh roots of Rehmannia glutinosa var. hueichingensis. On the basis of chemical and spectral analyses, the structures of jioglutosides A and B have been elucidated.

[Determination of adenosine in Rehmannia glutinosa Libosch. by HPLC].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2003
To establish a method to determine the contents of asenosine in different species of Rehmannia glutinosa.The contents were determined by HPLC, with a column of KYWG-C18 as stationary phase, 6% ace tonitrile as mobile phase and detecting wavelength at 260 nm.Adenosine has a good linearity in the range of 0.002 mg/ml-0.01 mg/ml, Y = 1.7742 x 10(-4) + 8 ...

Immunosuppressive principles of Rehmannia glutinosa var. hueichingensis.

Planta medica, 1989
Separation of the immunosuppressive principles from Rehmanniae radix was done by monitoring hemolytic plaque-forming cells (HPFC) inhibitory activity to give two new phenethyl alcohol glycosides: jionosides A1 (4) and B1 (5), along with six known compounds: acetoside, isoacteoside, purpureaside C, echinacoside, and cistanosides A and F.

[Constituents of the dry roots of Rehmannia glutinosa Libosch].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 1992
From the extract of dry roots of Rehmannia glutimosa, fatty acids, palmitic acid, beta-sitosterol, daucosterol and sulfur (Ss) cyclic compound were isolated and identified. The latter four were isolated for the first time.
