Parnassia yunnanensis had been previously described based on mixed specimens containing materials partially belonging to Parnassia cacuminum, which makes the application of Parnassia yunnanensis ambiguous. Therefore, we lectotypified Parnassia yunnanensis and meanwhile synonymized Parnassia lanceolata var. oblongipetala under it. Parnassia yunnanensis var. longistipitata was found more similar ...
A fast method was developed by ultra high performance liquid chromatography (UHPLC) for simultaneous determination of polyphyllin I and polyphyllin II. Chemometric analyses including principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) based on UHPLC chromatography were used to evaluate 38 batches from six species of Paris. Variable importance of projectio...
Arbuscular mycorrhizal fungi (AMF) are important members of the plant microbiome and affect uptake transfer mineral elements by forming a symbiotic relationship with roots. Nitrogen (N), as an element, can directly growth development at different N levels. It has been confirmed that inoculation AMF improve efficiency utilization plants. However, there still fewer reports on dynamic between arbu...
BACKGROUND Total steroidal saponins extracted from the rhizome of Paris polyphylla Sm. var. yunnanensis (TSSPs) have been widely used in China for the treatment of abnormal uterine bleeding. We previously studied the main active constituents of TSSPs and their structure-activity relationships with respect to rat myometrial contractions. Tg (pennogenin tetraglycoside) was identified as one of th...
