Three new lignans (1, 2, and 8) and ten known ones (3-7, 9-13) were isolated from the roots of Vladimiria muliensis. Their structures and configurations were elucidated by means of spectroscopic techniques (IR, MS, NMR, and CD) and chemical methods. The isolated compounds were evaluated for their antioxidant and antibacterial activities. The antioxidant activity was the greatest for lignans 7 and 10 with IC50 values of 11.2 and 7.3 µM against DPPH radical, and of 1.6 and 1.7 µM against ABTS+ radical, respectively. Moreover, 7 also displayed broad-spectrum antibacterial activity with MIC values around 7.25 µg/mL.

Ethnopharmacological Relevance: As a representative local medicinal herb produced in China, Vladimiriae Radix (VR) has been proven to exert hepatoprotective and choleretic effects, with particular therapeutic efficacy in cholestatic liver injury (CLI), as demonstrated by the VR extract (VRE). However, the quality markers (Q-markers) of VRE for the treatment of CLI remain unclear.
Aim Of The Study: A new strategy based on the core element of "efficacy" was proposed, using a combination of spectrum-effect relationship, pharmacokinetics, and molecular docking methods to select and confirm Q-markers of VRE.

As our ongoing interest to search bioactive dimeric sesquiterpenes from the genus Vladimiria (Asteraceae), the plant of Vladimiria souliei was studied. Based on the repetitive chromatographic fractionation, a chemical investigation on the roots of Vladimiria souliei led to the isolation and the identification of four previously undescribed sesquiterpene dimers, vlasouliodes A-D (1-4). Their chemical structures were elucidated by comprehensive analysis of spectroscopic data, including HRESIMS, 1D and 2D NMR spectroscopic data.

Aucklandiae radix (AR, Muxiang), vladimiriae radix (VR, Chuanmuxiang), and inulae radix (IR, Tumuxiang) are widely used in clinical or folk medicine in China. Their Chinese names all have the Chinese character "Muxiang," which makes it confusable in usage, especially AR and VR, because VR was used as a substitute for AR during a historical period. The National Health Commission of the People's Republic of China has approved AR as a functional food.

Ethnopharmacological Relevance: Aucklandiae Radix (AR) and Vladimiriae Radix (VR), as commonly used traditional Chinese herbal medicine, were widely used in the treatment of gastrointestinal diseases. The two herbal medicines were warm, pungent and bitter. They entered the spleen, stomach, large intestine and gallbladder meridians, and had the effect of promoting qi circulation to relieve pain.

Background: The intestinal flora imbalance and metabolic disorders are closely related to the pathogenesis of ulcerative colitis (UC). As a commonly used herb for the treatment of gastrointestinal diseases, Vladimiriae Radix (VR) has been used for hundreds of years, and its main active ingredients are costunolide (COS) and dehydrocostus lactone (DEH). Clinical usage habits and previous studies have shown that the processed Vladimiriae Radix (pVR) seems to be more suitable for treating bowel disease than the raw Vladimiriae Radix (rVR), but there is still no relevant comparative study.
