Trigonella: A plant genus of the family FABACEAE.History, Early Modern 1451-1600: The period of history from 1451 through 1600 of the common era.Diosgenin: A spirostan found in DIOSCOREA and other plants. The 25S isomer is called yamogenin. Solasodine is a natural derivative formed by replacing the spiro-ring with a nitrogen, which can rearrange to SOLANINE.Melilotus: A plant genus of the family FABACEAE.Seeds: The encapsulated embryos of flowering plants. They are used as is or for animal feed because of the high content of concentrated nutrients like starches, proteins, and fats. Rapeseed, cottonseed, and sunflower seed are also produced for the oils (fats) they yield.Phytotherapy: Use of plants or herbs to treat diseases or to alleviate pain.Plant Extracts: Concentrated pharmaceutical preparations of plants obtained by removing active constituents with a suitable solvent, which is evaporated away, and adjusting the residue to a prescribed standard.Random Amplified Polymorphic DNA Technique: Technique that utilizes low-stringency polymerase chain reaction (PCR) amplification with single primers of arbitrary sequence to generate strain-specific arrays of anonymous DNA fragments. RAPD technique may be used to determine taxonomic identity, assess kinship relationships, analyze mixed genome samples, and create specific probes.
