Tansy
Tansy (''Tanacetum vulgare'') is a perennial, herbaceous flowering plant in the genus ''Tanacetum'' in the aster family, native to temperate Europe and Asia. It has been introduced to other parts of the world, including North America, and in some areas has become invasive. It is also known as common tansy, bitter buttons, cow bitter, or golden buttons. The Latin word ''vulgare'' means "common". Description Tansy is a flowering herbaceous plant with finely divided compound leaves and yellow, button-like flowers. It has a stout, somewhat reddish, erect stem, usually smooth, tall, and branching near the top. The leaves are alternate, long and are pinnately lobed, divided almost to the center into about seven pairs of segments, or lobes, which are again divided into smaller lobes having saw-toothed edges, giving the leaf a somewhat fern-like appearance. The roundish, flat-topped, button-like, yellow flower heads are produced in terminal clusters from mid-to-late summer. The ...

Inula Britannica
''Pentanema britannica'', the British yellowhead or meadow fleabane, is a Eurasian species of plant in the Asteraceae, daisy family. It is widespread across much of Europe and Asia, and sparingly naturalized in scattered locations in North America. ''Pentanema britannica'' is an erect herb up to 75 cm (30 inches) tall, with fine hairs but not the thick woolly coat characterizing some related species. Leaves are lance-shaped, up to 5 cm (2 inches) long. One plant produces a few heads, each on a long flower stalk. Each had contains 50-150 yellow ray flowers and 100-250 yellow disc flowers. The plant produces the flavonol axillarin. Medicinal uses ''Pentanema brittanica'' is used in Chinese Herbalism by harvesting and drying the flower. It has been used to treat sputum, as the Chinese found it to be beneficial when phlegm has accumulated in the bronchi. Other symptoms in which it has been found to be a clinical remedy for are nausea, vomiting, hiccups, and flatulence. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
O-methylated Flavonoid
The O-methylated flavonoids or methoxyflavonoids are flavonoids with methylations on hydroxyl groups (methoxy bonds). O-methylation has an effect on the solubility of flavonoids. Enzymes O-methylated flavonoids formation implies the presence of specific O-methyltransferase (OMT) enzymes which accept a variety of substrates. Those enzymes mediate the O-methylation on a specific hydroxyl group, like on 4' (example in ''Catharanthus roseus'') or 3' (example in rice) positions. Those positions can be ortho, meta, para and there can be a special 3-O-methyltransferase for the 3-OH position. Calamondin orange ('' Citrus mitis'') exhibits all of those activities.

Wyethia Bolanderi
''Agnorhiza bolanderi'' is a species of flowering plant known by the common name Bolander's mule's ears. It is endemic to California, where it is known only from a narrow section of the Sierra Nevada foothills about 275 kilometers long from Shasta County to Mariposa County.Ayres, D. R. and F. J. Ryan. (1999)Genetic diversity and structure of the narrow endemic ''Wyethia reticulata'' and its congener ''W. bolanderi'' (Asteraceae) using RAPD and allozyme techniques.American Journal of Botany 86 344-53. It grows in chaparral and grassland habitat, usually on serpentine soils. Description ''Agnorhiza bolanderi'' is a perennial herb growing from a thick taproot and caudex unit. This underground stem part helps it survive wildfire, which is common in its chaparral habitat. The aboveground stem grows up to 30 centimeters long. It is glandular and sticky in texture.

Catechols
Catechol ( or ), also known as pyrocatechol or 1,2-dihydroxybenzene, is a toxic organic compound with the molecular formula . It is the ''ortho'' isomer of the three isomeric benzenediols. This colorless compound occurs naturally in trace amounts. It was first discovered by destructive distillation of the plant extract catechin. About 20,000 tonnes of catechol are now synthetically produced annually as a commodity organic chemical, mainly as a precursor to pesticides, flavors, and fragrances. Catechol occurs as feathery white crystals that are very rapidly soluble in water. Isolation and synthesis Catechol was first isolated in 1839 by Edgar Hugo Emil Reinsch (1809–1884) by distilling it from the solid tannic preparation catechin, which is the residuum of catechu, the boiled or concentrated juice of ''Mimosa catechu'' (''Acacia catechu''). Upon heating catechin above its decomposition point, a substance that Reinsch first named ''Brenz-Katechusäure'' (burned catechu acid) ...
