Screening of ESR2-targeted anti-postmenopausal osteoporosis chemistry from Rehmanniae Radix Preparata based on affinity ultrafiltration with UPLC-QE-Orbitrap-MS.

Rehmanniae Radix Preparata, a processed form of the traditional Chinese medicinal plant Rehmannia glutinosa Libosch, has long been valued for its medicinal properties and use as a food. It is notably effective in treating postmenopausal osteoporosis. This study utilized C18 to separate and purify different concentrations of its eluent streams.

Using a Dual-Disease Target Mapping Network Pharmacology Approach, Verbascoside Ameliorates Osteoporosis by Activating Estrogen Signaling to Alleviate Oxidative Stress.

Background: Verbascoside, a compound classified as a phenylethanol glycoside in Dihuang, has been the subject of modern pharmacological investigations. These studies have revealed its noteworthy antioxidant, anti-inflammatory, memory-enhancing, neuroprotective, antitumor, and various other pharmacological properties. While verbascoside exhibits favorable antioxidant effects, its precise mechanism of action in ameliorating osteoporosis through the treatment of oxidative stress remains unclear.

Integrated cell metabolomics and network pharmacology approach deciphers the anti-testosterone deficiency mechanisms of Bushen Zhuanggu Tang.

Testicular dysfunction is distinguished by a deficiency in testosterone levels, which can be attributed to the occurrence of oxidative stress injury in Leydig cells. The empirical prescription known as Bushen Zhuanggu Tang, developed by a highly experienced traditional Chinese medicine practitioner with six decades of clinical expertize, aligns with the traditional Chinese medicine principle of "kidney governing bone". Researchers have demonstrated that the administration of BSZGT can effectively enhance testosterone production.
