Mechanism of the color deepening of secretory cavities in Atractylodes lancea during light and air exposure.

Ethnopharmacological Relevance: Atractylodes lancea is widely used as an herbal medicine and functional food in East Asia. The red hue of secretory cavities (SCs) in A. lancea rhizoma (ALR) serves as a marker of superior quality, though the mechanistic link between color deepening and volatile organic compounds (VOCs) under light/air exposure remains unclear.

Identification of candidate genes in sesquiterpenoid biosynthesis of Atractylodes lancea through combined metabolomic and transcriptomic analysis.

Atractylodes lancea is a type of traditional Chinese medicine whose rhizome is rich in sesquiterpenoids. However, the mechanisms underlying the synthesis and metabolism of sesquiterpenoids in A. lancea remain poorly discovered.

[Tissue distribution of volatile compounds in secretory cavities of different rhizome sections of wild Atractylodes lancea and A. lancea transplanted for different years].

Laser capture microdissection(LCM) combined with gas chromatography-mass spectrometry(GC-MS) was employed to investigate the distribution of volatile compound in the secretory cavities of different tissues(cortex, phloem, xylem, and pith) in different rhizome sections of wild Atractylodes lancea. The same method was used to study the metabolic characteristics of the volatile compounds in the secretory cavities of different rhizome tissues of A. lancea transplanted for 1-3 years.

Allochthonous Isolates Boost Herb Quality at the Cost of Rhizome Growth.

is a perennial herb whose rhizome (AR) is a valuable traditional Chinese medicine with immense market demand. The cultivation of faces outbreaks of root rot and deterioration in herb quality due to complex causes. Here, we investigated the effects of spp.

Genetic diversity and population divergence of Leonurus japonicus and its distribution dynamic changes from the last interglacial to the present in China.

Background: Leonurus japonicus, a significant medicinal plant known for its therapeutic effects on gynecological and cardiovascular diseases, has genetic diversity that forms the basis for germplasm preservation and utilization in medicine. Despite its economic value, limited research has focused on its genetic diversity and divergence.
