QUINACRINE FLUORESCENCE STUDIES IN PARIS POLYPHYLLA

Canadian Journal of Genetics and Cytology, 1980
The chromosomes of Paris polyphylla Smith (2n = 10, 20) are the largest in the plant kingdom. They possess large regions of reduced fluorescence in addition to discrete fine banding. Excluding the 'bubbling', an effect of fixation, the discrete finer banding pattern is very constant and specific for each chromosome type.

Sodium Bisulfite Improves Rhizome Yield and Quality inParis polyphylla

Planta Medica, 2009
Rhizomes of the perennial herb Paris polyphylla have been used in traditional Chinese medicine for hundreds of years. Agricultural production of the rhizomes requires 7-10 years, which is too long to meet the demand of the medicinal industry. Therefore, studies on improving the yield of the herb and shortening the culturing period are imperative.

[Studies on the parasites of Paris polyphylla var. yunnanensis].

Wei sheng wu xue bao = Acta microbiologica Sinica, 2004
Two bacteria and three fungi were isolated from the hypogeal stems of Paris polyphylla var. yunnanensis. The bacteria were identified as Bacillus cereus and Pseudomonas alcaligenes, and the fungi were identified as Periconia sp., Pachnocybe albida and Hormomyces paridiphilus. The results on liquid culture of B. cereus, P.

Anti-leukemia steroidal saponins from Paris polyphylla var. yunnanensis

Phytochemistry
From the rhizomes of Paris polyphylla var. yunnanensis (Franch.) Hand.-Mazz., five novel steroidal saponins (Polyphyllozsides A-E, 1-5) and four known steroidal saponins (6-9) were isolated. The biological activities of the nine compounds against human hematologic malignancy cell lines (U-937, THP-1 and Jurkat) was evaluated using a cytotoxicity assay.

Study on Anti-fatigue Effects and Mechanisms of Polysaccharide from Paris polyphylla

Doklady Biochemistry and Biophysics
The objectives of this study were to investigate the anti-fatigue effects of Paris polyphylla polysaccharide component 1 (PPPm-1) and explore its mechanisms. A mouse model of exercise-induced fatigue was established by weight-bearing swimming to observe the effects of different concentrations of PPPm-1 on weight-bearing swimming time.
