Alkaloid
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids

Papaveraceae
The Papaveraceae are an economically important family of about 42 genera and approximately 775 known species of flowering plants in the order Ranunculales, informally known as the poppy family. The family is cosmopolitan, occurring in temperate and subtropical climates (mostly in the northern hemisphere), but almost unknown in the tropics. Most are herbaceous plants, but a few are shrubs and small trees. The family currently includes two groups that have been considered to be separate families: Fumariaceae and Pteridophyllaceae. Description The plants may be annual, biennial, or perennial. Usually herbaceous, a few species form shrubs or evergreen trees. They are lactiferous, producing latex, which may be milky or watery, coloured or plain. All parts contain a well-developed duct system (these ducts are called "laticifers"), producing a milky latex, a watery white, yellow or red juice. The simple leaves are alternate or sometimes whorled. They have petioles and are not enc ...

Berberidaceae
The Berberidaceae are a family of 18 genera of flowering plants commonly called the barberry family. This family is in the order Ranunculales. The family contains about 700 known species, of which the majority are in ''Berberis''. The species include trees, shrubs and perennial herbaceous plants. General The APG IV system of 2016 recognises the family and places it in the order Ranunculales in the clade eudicots. In some older treatments of the family, Berberidaceae only included four genera (''Berberis, Epimedium, Mahonia, Vancouveria''), with the other genera treated in separate families, Leonticaceae (''Bongardia, Caulophyllum, Gymnospermium, Leontice''), Nandinaceae (''Nandina''), and Podophyllaceae (''Achlys, Diphylleia, Dysosma, Jeffersonia, Podophyllum, Ranzania, Sinopodophyllum''). ''Mahonia'' is very closely related to ''Berberis'', and included in it by many botanists. However, recent DNA-based phylogenetic research has reinstated ''Mahonia'', though with a handfu ...

Lauraceae
Lauraceae, or the laurels, is a plant family that includes the true laurel and its closest relatives. This family comprises about 2850 known species in about 45 genera worldwide (Christenhusz & Byng 2016 ). They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as ''Sassafras'', are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. The genus ''Cassytha'' is unique in the Lauraceae in that its members are parasitic vines. Most laurels are highly-poisonous. Overview The family has a worldwide distribution in tropical and warm climates. The Lauraceae are important components of tropical forests ranging from low-lying to montane. In several forested regions, Lauraceae are among the top five families in terms of the number of species present. The Lauraceae give their name to habitats know ...

Ranunculaceae
Ranunculaceae (buttercup or crowfoot family; Latin "little frog", from "frog") is a family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide. The largest genera are ''Ranunculus'' (600 species), ''Delphinium'' (365), ''Thalictrum'' (330), ''Clematis'' (325), and ''Aconitum'' (300). Description Ranunculaceae are mostly herbaceous annuals or perennials, but some are woody climbers (such as ''Clematis'') or shrubs (e.g. ''Xanthorhiza''). Most members of the family have bisexual flowers which can be showy or inconspicuous. Flowers are solitary, but are also found aggregated in cymes, panicles, or spikes. The flowers are usually radially symmetrical but are also found to be bilaterally symmetrical in the genera ''Aconitum'' and ''Delphinium''. The sepals, petals, stamens and carpels are all generally free (not fused), the outer flower segments typically number four or five. The outer stamens may be modified to produce only nectar, as in Aqui ...

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 ...

Benzylisoquinoline Alkaloids
Substitution of the heterocycle isoquinoline at the C1 position by a benzyl group provides 1‑benzylisoquinoline, the most widely examined of the numerous benzylisoquinoline structural isomers. The 1-benzylisoquinoline moiety can be identified within numerous compounds of pharmaceutical interest, such as moxaverine; but most notably it is found within the structures of a wide variety of plant natural products, collectively referred to as benzylisoquinoline alkaloids. This class is exemplified in part by the following compounds: papaverine, noscapine, codeine, morphine, apomorphine, berberine, tubocurarine. Biosynthesis (''S'')- Norcoclaurine (higenamine) has been identified as the central 1-benzyl-tetrahydro-isoquinoline precursor from which numerous complex biosynthetic pathways eventually emerge. These pathways collectively lead to the structurally disparate compounds comprising the broad classification of plant natural products referred to as benzylisoquinoline alkaloids (B ...
