A plant genus of the family ASTERACEAE. M. chamomilla appears similar to Anthemis but this flower disk is conical and hollow and lacks chaffy bract scales and the odor is weaker. The common name of 'manzanilla' is confused with other meanings of the word. 'Matricaria chamomilla sensu' is classified by some as Tripleurospermum perforata. Other plants with similar common names include CHAMAEMELUM; TRIPLEUROSPERMUM and ANTHEMIS.
Common name for several daisy-like plants (MATRICARIA; TRIPLEUROSPERMUM; ANTHEMIS; CHAMAEMELUM) native to Europe and Western Asia, now naturalized in the United States and Australia.
A plant genus of the family ASTERACEAE that is similar to CONYZA. Members contain SESQUITERPENES.
Hydrocarbons with more than one triple bond; or an oxidized form of POLYENES. They can react with SULFUR to form THIOPHENES.
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.
SESQUITERPENES cyclized into two adjoining cyclohexane rings but with a different configuration from the ARTEMISININS.
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.
A plant genus of the family SALICACEAE. Balm of Gilead is a common name used for P. candicans, or P. gileadensis, or P. jackii, and sometimes also used for ABIES BALSAMEA or for COMMIPHORA.
A nutritious food consisting primarily of the curd or the semisolid substance formed when milk coagulates.
Mammalian pigment cells that produce MELANINS, pigments found mainly in the EPIDERMIS, but also in the eyes and the hair, by a process called melanogenesis. Coloration can be altered by the number of melanocytes or the amount of pigment produced and stored in the organelles called MELANOSOMES. The large non-mammalian melanin-containing cells are called MELANOPHORES.
Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
