Six new triterpene saponins, ilexasprellanosides A–F (1–6, resp.), together with eleven known compounds were isolated from the roots of Ilex asprella. The new saponins were characterized as ursa‐12,18‐dien‐28‐oic acid 3‐O‐β‐D‐xylopyranoside (1), 19α‐hydroxyursolic acid 3‐O‐β‐D‐(2′‐O‐acetylxylopyranoside) (2), 19α‐hydroxyursolic acid 3‐O‐β‐D‐glucuronopyranoside (3), 3β,19α‐dihydroxyolean‐12‐en‐23,28‐dioic acid 28‐O‐β‐D‐glucopyranoside (4), 19α‐hydroxyoleanolic acid 3‐O‐β‐D‐(2′‐O… 
Eleven New Triterpenoid Glycosides from the Roots of Ilex asprella
TLDR
All the saponins isolated showed no significant effects against respiratory syncytial virus (RSV) and lipopolysaccharide‐induced nitric oxide production in Raw264.7 macrophages.
Anticomplement triterpenoids from the roots of Ilex asprella.
Transcriptomic Comparison Reveals Candidate Genes for Triterpenoid Biosynthesis in Two Closely Related Ilex Species
TLDR
This study is the first exploration to profile the transcriptome of I. pubescens and identifies a series of candidate genes involved in the biosynthetic pathway of triterpenoid saponins, providing new insight into their biosynthesis at transcriptome level.
Triterpene Saponins from the Roots of Ilex asprella.
Six new triterpene saponins, ilexasprellanoside A (I) and ilexasprellanosides B-F (II) are isolated along with eleven known compounds from the roots of Ilex asprella.
Asprellcosides B of Ilex asprella Inhibits Influenza A Virus Infection by Blocking the Hemagglutinin- Mediated Membrane Fusion
TLDR
Findings demonstrate that Asprellcosides B inhibits the influenza A virus, through a specific binding to the HA, resulting in the blockade of the HA-mediated membrane fusion.
