Introduction: Andrographolide is a bioactive component found in the medicinal herb Andrographis paniculata (Burm. f.) Wall. ex Nees (Family-Acanthaceae) is well-known for its ability to cure liver disorders and as a bitter tonic.
Objective: In this study, the rate of degradation of andrographolide was examined over the course of a year of storage.
Materials And Methods: New and old (1-year storage) A. paniculata powder samples were used in the study. High-performance liquid chromatography (HPLC) was used to assess the concentration of andrographolide after its extraction using ethanol as the solvent.
Results: The findings demonstrated a 69.26% progressive deterioration of andrographolide over the storage period. Temperature and crystallinity are two factors that affect how quickly andrographolide degrades.
Conclusion: The results emphasize how crucial it is to retain the effectiveness of A. paniculata extract by avoiding prolonged storage or by providing ideal storage conditions.

In this manuscript, the effects of two extracts from were tested: (a) an extract titrated to 49.7% of andrographolide and obtained from leaves of the plant: (b) the pure andrographolide titrated to 99%. The extracts were dissolved in 1-butanol and tested on tumor lines (MCF7 and SH-SY5Y) and the non-tumor line (Huvec) to understand the effects on cell proliferation.

Aim: Insufficient quality control and limited dissolution of extract capsules restricts their bioavailability and hinder the clinical use for treating mild coronavirus disease 2019 (COVID-19) patients.
Objective: This study aims to investigate pharmacokinetics and safety of high-dosage ethanolic extract (equivalent to 180 or 360 mg/day of andrographolide), relevant dosages used for mild COVID-19 treatment.
Methods: An open-label, single-dose, and repeated-dose conducted in healthy volunteers.

MicroRNA-222 (miR-222) plays a crucial role in neurodegeneration and is up-regulated in Alzheimer's disease (AD) patients. Andrographolide (Andro) has been reported to have anti-inflammatory and neuroprotective effects, showing potential for treating AD. The relationship between Andro's anti-AD mechanism and the regulation of miR-222 was discussed in this study.

Drug nanocrystal engineering is an attractive pharmaceutical approach to enhancing the oral bioavailability of poorly soluble drugs. The mechanism of drug nanocrystal stabilization, however, is unclear. Here we developed andrographolide nanocrystals (AG-NCs) with various nonionic surfactants (Pluronic-F127, TPGS, or Brij-S20).

The purpose of this study was to explore the inhibitory effect of andrographolide on the expression of key regulatory genes involved in the biofilm formation of Staphylococcus epidermidis (SE). Taking the film-producing strain Staphylococcus epidermidis SE1457 as the research object, the effect of andrographolide on the formation of Staphylococcus epidermidis biofilms was analyzed via crystal violet staining, and biofilm models of SE adhesion, aggregation and maturity were established in vitro. RT‒PCR was used to detect the effects of the expression of icaA-, atlE-, aap- and luxS-related genes of andrographolide on biofilm formation in SE.
