Cnidium Monnieri
''Cnidium monnieri'' (L.) Cusson ex Juss., Monnier's snowparsley, is a flowering plant species in the genus ''Cnidium''. Also known as Shechuangzi, Osthole, Jashoshi, Cnidii Fructus (Fruits of Cnidium). It may be confused with ''Bacopa monnieri'', ''Ligusticum officinale'' (syn. ''Cnidium officinale''), both similar but different plants. The coumarins osthol, imperatorin and xanthotoxol can be found in ''C. monnieri''. Naming ''Cnidium monnieri'' was already described and the name validly published by Carl Linnaeus. It was Pierre Cusson, however, who reclassified it into today's valid botanical systematics in 1787. Taxonomy ''Cnidium monnieri'' is a species in the genus ''Cnidium'' which contains approximately 11 to 35 species and belongs to thfamilyof thApiaceae(carrot family). Characteristics Plants annual, 10–60(–80) cm. Taproot 2–3 mm thick. Stem solitary, striate, scabrous. Lower petioles 3–8 cm; blade ovate-lanceolate, 3–8 × 2–5 cm, 2â ...

Chemical Compound
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound. A compound can be transformed into a different substance by a chemical reaction, which may involve interactions with other substances. In this process, bonds between atoms may be broken and/or new bonds formed. There are four major types of compounds, distinguished by how the constituent atoms are bonded together. Molecular compounds are held together by covalent bonds; ionic compounds are held together by ionic bonds; intermetallic compounds are held together by metallic bonds; coordination complexes are held together by coordinate covalent bonds. Non-stoichiometric compounds form a disputed marginal case. A chemical formula specifies the number of atoms of each element in a compound molecule, using the s ...

Derivative (chemistry)
In chemistry, a derivative is a compound that is derived from a similar compound by a chemical reaction. In the past, derivative also meant a compound that ''can be imagined to'' arise from another compound, if one atom or group of atoms is replaced with another atom or group of atoms, but modern chemical language now uses the term structural analog for this meaning, thus eliminating ambiguity. The term "structural analogue" is common in organic chemistry. In biochemistry, the word is used for compounds that at least theoretically can be formed from the precursor compound. Chemical derivatives may be used to facilitate analysis. For example, melting point (MP) analysis can assist in identification of many organic compounds. A crystalline derivative may be prepared, such as a semicarbazone or 2,4-dinitrophenylhydrazone (derived from aldehydes or ketones), as a simple way of verifying the identity of the original compound, assuming that a table of derivative MP values is available ...

Coumarin
Coumarin () or 2''H''-chromen-2-one is an aromatic organic chemical compound with formula . Its molecule can be described as a benzene molecule with two adjacent hydrogen atoms replaced by a lactone-like chain , forming a second six-membered heterocycle that shares two carbons with the benzene ring. It can be placed in the benzopyrone chemical class and considered as a lactone. Coumarin is a colorless crystalline solid with a sweet odor resembling the scent of vanilla and a bitter taste. It is found in many plants, where it may serve as a chemical defense against predators. By inhibiting synthesis of vitamin K, a related compound is used as the prescription drug warfarin – an anticoagulant – to inhibit formation of blood clots, deep vein thrombosis, and pulmonary embolism. Etymology Coumarin is derived from ''coumarou'', the French word for the tonka bean. The word ''tonka'' for the tonka bean is taken from the Galibi (Carib) tongue spoken by natives of French G ...

Angelica Archangelica
''Angelica archangelica'', commonly known as garden angelica, wild celery, and Norwegian angelica, is a biennial plant from the family Apiaceae, a subspecies of which is cultivated for its sweetly scented edible stems and roots. Like several other species in Apiaceae, its appearance is similar to several poisonous species (''Conium'', '' Heracleum'', and others), and should not be consumed unless it has been identified with absolute certainty. Synonyms include ''Archangelica officinalis'' Hoffm. and ''Angelica officinalis'' Moench. Description and distribution During its first year, it grows only leaves, but during its second year, its fluted stem can reach a height of 2.5 meters (just over 8 feet), and the root is used in flavoring preparations. Its leaves consist of numerous small leaflets divided into three principal groups, each of which is again subdivided into three lesser groups. The edges of the leaflets are finely toothed or serrated. The flowers, which blossom in July, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angelica Pubescens
''Angelica pubescens'' is a plant in the family Apiaceae, native to Japan and China. The Japanese common name is shishiudo and the Chinese common name is 猪独活, du huo. It is a herbaceous perennial plant growing to 1–2 m tall with tripinnate leaves up to 1 m long, the leaflets being 5–10 cm long. The flowers are white, produced in large umbels. The young stems and leaves are edible. Shishiudo is often mistaken with udo. The plant is used in traditional Chinese medicine Traditional Chinese medicine (TCM) is an alternative medical practice drawn from traditional medicine in China. It has been described as "fraught with pseudoscience", with the majority of its treatments having no logical mechanism of action ....
