Article Abstract
Phytochemical investigation on roots extract of (L.) Holub led to the isolation of two novel ecdysteroids, 11-hydroxy-25-inokosterone (1) and 11-hydroxy-24, 25 -amarasterone A (2), along with 20 known constituents. The structures of novel compounds were confirmed by NMR and ECD spectroscopy. Compounds and exhibited anticomplementary activity with classical pathway, their CH values were 138.4 ± 0.07 µg·mL and 158.3 ± 0.09 µg·mL, respectively.

Introduction: Myricariae Ramulus (MR) is a traditional anti-inflammatory Tibetan medicine derived from the branches and leafy twigs of various Myricaria plants, such as Myricaria wardii Marquand.
Objective: This study performed spectrum-effect analyses on 15 batches of MR, sourced from various origins and medicinal parts, to identify quality markers associated with its anti-inflammatory effects.
Materials And Methods: The anti-inflammatory effects of different extracts and fractions from M.

Article Synopsis
- EU, a tree species from China, has significant economic and medicinal value, especially its bark and leaves used in traditional Chinese medicine since the first century BC.
- In recent years, there's been increased research on polysaccharides from EU, which exhibit diverse biological functions like immunomodulatory, antioxidant, and anti-inflammatory activities.
- This review highlights advancements in the extraction, purification, and application of EU polysaccharides, suggesting their potential in medicine, particularly as alternatives to other immunomodulatory agents.
