Two novel furostanol saponins from Ophiopogon japonicus

Journal of Asian Natural Products Research, 2009
Two novel furostanol saponins were isolated from the fresh tubers of Ophiopogon japonicus. Comprehensive spectroscopic analysis allowed the chemical structures of the compounds to be assigned as (25R)-26-[(O-beta-d-glucopyranosyl-(1 --> 2)-beta-d-glucopyranosyl)]-22alpha-hydroxyfurost-5-ene-3-O-beta-d-xylopyranosyl-(1 --> 4)-O-[alpha-l-rhamnopyranosyl-(

A new C27-steroidal glycoside from Ophiopogon japonicus

Chinese Chemical Letters, 2008
Abstract A new C27-steroidal glycoside with three known compounds were isolated from the tuber of Ophiopogon japonicus (Thunb.) Ker-Gawl. Based on the spectral analysis, including HRMS, 1H NMR, 13C NMR, DEPT, 1H–1H COSY, HMQC and HMBC, their chemical structures were determined as pennogenin-3-O-α- l -rhamnopyranosyl-(1 → 2)-β- d -xylopyranosyl-(1 → 4)

Steroidal saponins from the fresh tubers of Ophiopogon japonicus

Phytochemistry Letters, 2016
Abstract Eleven novel furostanol saponins, named ophiofurospisides C–E, G–N (1–3, 5–12), one new spirostanol saponin, named ophiopogonin R (13), were isolated from the fresh tubers of Ophiopogon japonicus. Their structures were determined on the basis of spectroscopic techniques (1D and 2D NMR) and HRESIMS.

[Analysis of polysaccharides contents in Ophiopogon japonicus by NIR].

Guang pu xue yu guang pu fen xi = Guang pu, 2014
In the present paper the polysaccharides in Ophiopogon japonicus was analysed quantitatively by using near infrared spectroscopy. The spectral characteristics of the primary ingredients in ophiopogonis were obtained by applying first derivative, second derivative, smoothing, SNV (standard normal variate), and MSC (multiple scatter correction), and the ...

[Study on endophyte and the growth stages of Ophiopogon japonicus].

Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2007
To study on the relationship between the endophyte and the life cycle of Ophiopogon japonicus in Zhejiang.Sample roots of Ophiopogon japonicus at different growth stages were thoroughly washed and cut into small fragments, then cleared (removing cytoplasmic contents from cells) using hot 10% KOH and stained with acid fuchsin (alternative stain).

[Simultaneous determination of three homoisoflavonoids in Ophiopogon japonicus by HPLC].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2012
Three homoisoflavonoids, 6-aldehydo-3-ophiopogonanone A, methyl ophiopogonanone A and ophiopogonanone A from Ophiopogon japonicus were analyzed simultaneously by HPLC with acetonitrile-water containing 0.5% H3 PO4 (58:42) as the mobile phase, and the detection wavelength was set at 296 nm (0-14 min) and 275 nm (14-22 min).

[Exploration of Ophiopogon japonicus new parts for medicine material].

Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2015
To explore the contents of polysaccharides and flavones in different parts of Ophiopogon japonicus for instead of Radix Ophiopgonis as medisine materials.The content of polysaccharides was quantified by colorimetry, content of total flavones was determined by spectrophotometry.The content of total flavones in the leaf was distinctly higher than that in
