BACKGROUND Panax notoginseng is an important Chinese medicinal plant. Dammarene-type triterpenoid saponins are main pharmacologically effective compounds in P. notoginseng. This study aims to investigate the formation and accumulation of saponins in P. notoginseng roots during germination and juvenile stage. METHODS P. notoginseng seeds were collected and stored in wet sand. After germination...

Stroke is the third leading cause of death and the first cause of adult disability in industrial countries [1]. It is charicaterized by hemiplegia, hemianopsia, aphasia, mouth askew and sever sequelae. It is considered that an ischemic disease without any specific treatment method and few effective drugs such as tPA (human tissue-type plasminogen activator) and Edarovone with specific therapeut...

Ilex asprella, which contains abundant α-amyrin type triterpenoid saponins, is an anti-influenza herbal drug widely used in south China. In this work, we first analysed the transcriptome of the I. asprella root using RNA-Seq, which provided a dataset for functional gene mining. mRNA was isolated from the total RNA of the I. asprella root and reverse-transcribed into cDNA. Then, the cDNA library...

BACKGROUND Cycloartane triterpenoids exhibited anticancer effects. This study aims to identify any potential novel anticancer cycloartane triterpenoids from Cimicifuga foetida L. rhizome (Sheng ma) and the mode of actions. METHODS Cycloartane triterpenoids were isolated from the C. foetida rhizome by a series of column chromatography and identified by IR, MS and NMR. Their anticancer effects ...

Eleven new furostanol saponins, typaspidosides B-L (1-11), one new spirostanol saponin, typaspidoside M (12), and five known spirostanol saponins, 25S-atropuroside (13), neoaspidistrin (14), (25S)-pratioside D1 (15), 25S-aspidistrin (16) and 25S-neosibiricoside (17) were isolated from the rhizomes of Aspidistra typica Baill. The structures of the new compounds were established using 1D and 2D N...

Two new 3,4-seco-cycloartane triterpenes, named sootepins H (1) and I (2), were isolated from the ethyl acetate extract of the leaves and twigs of Gardenia sootepensis. Their structures were elucidated on the basis of 1D- and 2D-nuclear magnetic resonance (NMR) analysis, as well as high-resolution mass spectrometry (HR-MS), infrared (IR), and ultra violet (UV).

Phytochemical investigation of the n-BuOH extract of the rhizomes of Anemone rivularis var. flore-minore led to the isolation of five new oleanane-type triterpenoid saponins 1-5, together with five known saponins 6-10. Their structures were determined by the extensive use of 1D and 2D NMR experiments, along with ESIMS analyses and acid hydrolysis. The aglycone of 4 and 5 was determined as 21α-h...

many different plant species synthesize triterpenoid saponins as part of their normal programme of growth and development. examples include plants that are exploited as sources of drugs. interest in these molecules stems from their medicinal properties, antimicrobial activity, and their likely role as determinants of plant disease resistance. daisy (bellis perennis l.) accumulates triterpenoid ...
