Variation in floral sex allocation in Polygonatum odoratum (Liliaceae).
BACKGROUND AND AIMS It is well known that resource allocation to male and female functions can be highly variable in hermaphroditic plants. The purpose of this study was to investigate variations in sexual investment at different levels (flower, plant and population) in Polygonatum odoratum, a plant with sequentially opening flowers. METHODS Pollen and ovule production in base, middle and top...
متن کاملA Review on Plants of Genus Polygonatum
Plants of genus Polygonatum (Ruscaceae) are widely used in traditional medicine to cure many diseases such as ageing, antioxidative action, insecticidal, antiherpetic, antinociception and aphrodisiac. A variety of phytoconstituents has been isolated from the Polygonatum species which include lignans, flavonoids, coumarins, steroids, terpenes, fatty acids and aliphatic long chain compounds. Anti...
متن کاملPolygonatum odoratum lectin promotes BECN1 expression and induces autophagy in malignant melanoma by regulation of miR1290
Autophagy is not only a survival response to growth-factor or nutrient deprivation but also an important mechanism for tumor-cell suicide, including melanoma. Polygonatum odoratum lectin (POL) displays apoptosis- and autophagy-inducing effects in many human tumors. POL also inhibits the growth of melanoma cells, but its role and molecular mechanism in malignant melanoma remain unclear. In this ...
متن کاملOptimization and Composition of Volatile Oil from Polygonatum odoratum (Mill Druce) using Supercritical Fluid Extraction
Purpose: To determine the effects of temperature, pressure and extraction time on oil yield obtained from Polygonatum odoratum as well as the optimum processing conditions for supercritical carbon dioxide (CO2) extraction. Methods: Supercritical CO2 extraction technology was adopted in this experiment to study the process of extraction of volatile oil from Polygonatum odoratum while gas chromat...
متن کاملOptimization of Alkaline Extraction and Bioactivities of Polysaccharides from Rhizome of Polygonatum odoratum
The present study is to explore the optimal extraction parameters, antioxidant activity, and antimicrobial activity of alkaline soluble polysaccharides from rhizome of Polygonatum odoratum. The optimal extraction parameters were determined as the following: NaOH concentration (A) 0.3 M, temperature (B) 80 °C, ratio of NaOH to solid (C) 10-fold, and extraction time (D) 4 h, in which ratio of NaO...
