Trigonella foenum-graecum seeds from Shanxi Province of China were used in this study. The chemical standards of UDP-glucose, UDP-rhamnose, UDP-xylose, diosgenin, yamogenin, cholesterol, β-sitosterol, ergosterol, brassicasterol, campesterol, kaempferol, quercetin, myricetin, protopanoxadiol, ursolic acid, trillin, prosapogenin A (α-L-rhamnopyranosyl-(1 → 2)-β-D-glucopyranoside-3-O-diosgenin), zingiberoside A1 (α-L-rhamnopyranosyl-(1 → 2)-β-D-glucopyranoside-3-O-yamogenin), and dioscin (α-L-rhamnopyranosyl-(1 → 4)-[α-L-rhamnopyranosyl-(1 → 2)]-β-D-glucopyranoside-3-O-diosgenin) were purchased from Shanghai Yuanye Biotechnology Co., Ltd. (Shanghai, China). The ruscogenin and stigmasterol standards were ordered from Chengdu HerbPurify Biotechnology Co., Ltd. (Chengdu, China). High performance liquid chromatography (HPLC)-grade acetonitrile or methanol (Thermo Fisher Scientific, United States) was used for HPLC and liquid chromatograph-mass spectrometer (LC-MS) analysis.

All solvents and reagents used in extraction and analyses were of analytical grade. Formic acid, methanol, ethyl acetate, and acetic acid were purchased from Sigma. The reference compounds ophiopogonin A, ophiopogonin C, prosapogenin A, ophiopogonin D, and ophiopogonin D were obtained from Shanghai Yuanye Bio-Technology Co. Ltd. The purity of all reference compounds was > 98 %. The glass plates for HPTLC (silica gel 60 F254, 20 × 10 cm) were purchased from Merck Millipore.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
