Annona Squamosa
''Annona squamosa'' is a small, well-branched tree or shrub from the family Annonaceae that bears edible fruits called sugar-apples or . It tolerates a tropical lowland climate better than its relatives ''Annona reticulata'' and ''Annona cherimola'' (whose fruits often share the same name) helping make it the most widely cultivated of these species. ''Annona squamosa'' is a small, semi-(or late) deciduous, much-branched shrub or small tree tall similar to soursop ('' Annona muricata''). Description The fruit of ''A. squamosa'' (sugar-apple) has sweet whitish pulp, and is popular in tropical markets. Stems and leaves Branches with light brown bark and visible leaf scars; inner bark light yellow and slightly bitter; twigs become brown with light brown dots (lenticels – small, oval, rounded spots upon the stem or branch of a plant, from which the underlying tissues may protrude or roots may issue). Thin, simple, alternate leaves occur singly, long and wide; rounded at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sugar-apple
The sugar-apple or sweet-sop is the edible fruit of ''Annona squamosa'', the most widely grown species of '' Annona'' and a native of tropical climate in the Americas and West Indies. Spanish traders aboard the Manila galleons docking in the Philippines brought it to Asia. The fruit is spherical-conical, in diameter and long, and weighing , with a thick rind composed of knobby segments. The color is typically pale green through blue-green, with a deep pink blush in certain varieties, and typically has a bloom. It is unique among ''Annona'' fruits in being segmented; the segments tend to separate when ripe, exposing the interior. The flesh is fragrant and sweet, creamy white through light yellow, and resembles and tastes like custard. It is found adhering to seeds forming individual segments arranged in a single layer around a conical core. It is soft, slightly grainy, and slippery. The hard, shiny seeds may number 20–40 or more per fruit and have a brown to black coat, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitidulidae
The sap beetles, also known as Nitidulidae, are a family (biology), family of beetles. They are small (2–6 mm) ovoid, usually dull-coloured beetles, with knobbed antenna (biology), antennae. Some have red or yellow spots or bands. They feed mainly on decaying vegetable matter, over-ripe fruit, and sap. Sap beetles coexist with fungi species and live in habitats of coniferous trees. They are found all across Europe and Siberia and are the biggest nutudulid species known in those areas. There are a few Pest (organism), pest species. An example of a pest species is the Stelidota geminata, strawberry sap beetle that infest crops in Brazil between the months of August and February. * the picnic beetle, ''Glischrochilus quadrisignatus'' * the dusky sap beetle, ''Carpophilus lugubris'' * the Stelidota geminata, strawberry sap beetle, ''Stelidota geminata'' * the small hive beetle, ''Aethina tumida'' The oldest unambiguous fossils of the family date to the Early Cretaceous, belong ...

Quercetin-3-O-glucoside
Isoquercetin, isoquercitrin or isotrifoliin is a flavonoid, a type of chemical compound. It is the 3-''O''- glucoside of quercetin. Isoquercitrin can be isolated from various plant species including ''Mangifera indica'' ( mango) and '' Rheum nobile'' (the Noble rhubarb). It is also present in the leaves of ''Annona squamosa'', '' Camellia sinensis'' (tea). and '' Vestia foetida'' Spectral data The lambda-max for isoquercetin is 254.8 and 352.6 nm. Potential clinical uses Isoquercetin is presently being investigated for prevention of thromboembolism in selected cancer patients and as an anti- fatigue agent in kidney cancer patients treated with sunitinib. There is a single case report of its use in the successful treatment of prurigo nodularis, a difficult to treat pruritic eruption of the skin. However it belongs to the PAINS (Pan-assay interference compounds) categories of chemicals. References See also * Quercitrin Quercitrin is a glycoside formed from the fl ...

Flavonoid
Flavonoids (or bioflavonoids; from the Latin word ''flavus'', meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans. Chemically, flavonoids have the general structure of a 15-carbon skeleton, which consists of two phenyl rings (A and B) and a heterocyclic ring (C, the ring containing the embedded oxygen). This carbon structure can be abbreviated C6-C3-C6. According to the IUPAC nomenclature, they can be classified into: *flavonoids or bioflavonoids *isoflavonoids, derived from 3-phenyl chromen-4-one (3-phenyl-1,4-benzopyrone) structure *neoflavonoids, derived from 4-phenylcoumarine (4-phenyl-1,2-benzopyrone) structure The three flavonoid classes above are all ketone-containing compounds and as such, anthoxanthins ( flavones and flavonols). This class was the first to be termed bioflavonoids. The terms flavonoid and bioflavonoid have also been more loosely used to describe non ...

Reticuline
Reticuline is a chemical compound found in a variety of plants including ''Lindera aggregata'', ''Annona squamosa'', and '' Ocotea fasciculata'' (also known as ''Ocotea duckei''). It is based on the benzylisoquinoline structure. Reticuline is one of the alkaloids found in opium, and experiments in rodents suggest it possesses potent central nervous system depressing effects. It is the precursor of morphine and many other alkaloids. It is also toxic to dopaminergic neurons causing a form of atypical parkinsonism known as Guadeloupean Parkinsonism. Metabolism 3'-hydroxy-N-methyl-(S)-coclaurine 4'-O-methyltransferase uses ''S''-adenosyl methionine and 3'-hydroxy-''N''-methyl-(''S'')- coclaurine to produce ''S''-adenosylhomocysteine and (''S'')-reticuline. Reticuline oxidase uses (''S'')-reticuline and O2 to produce (''S'')-scoulerine and H2O2. Salutaridine synthase uses (''R'')-reticuline, NADPH, H+, and O2 to produce salutaridine, NADP+, and H2O. Salutaridine can then be t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 xumuk.ru Alkaloids are produced by a large variety of organisms including , , Medicinal plant, plants, an ...

Diterpenoid
Diterpenes are a class of chemical compounds composed of four isoprene units, often with the molecular formula C20H32. They are biosynthesized by plants, animals and fungi via the HMG-CoA reductase pathway, with geranylgeranyl pyrophosphate being a primary intermediate. Diterpenes form the basis for biologically important compounds such as retinol, retinal, and phytol. They are known to be antimicrobial and antiinflammatory. Structures As with most terpenes a huge number of potential structures exists, which may be broadly divided according to the number of rings present. Biosynthesis Diterpenes are derived from the addition of one IPP unit to FPP to form geranylgeranyl-pyrophosphate (GGPP). From GGPP, structural diversity is achieved mainly by two classes of enzymes; the diterpene synthases and cytochromes P450. Several diterpenes are produced by plants and cyanobacteria. GGPP is also the precursor for the synthesis of the phytane by the action of the enzyme geranylger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raspberry
The raspberry is the edible fruit of a multitude of plant species in the genus ''Rubus'' of the rose family, most of which are in the subgenus '' Idaeobatus''. The name also applies to these plants themselves. Raspberries are perennial with woody stems. World production of raspberries in 2020 was 895,771 tonnes, led by Russia with 20% of the total. Description A raspberry is an aggregate fruit, developing from the numerous distinct carpels of a single flower. What distinguishes the raspberry from its blackberry relatives is whether or not the torus ( receptacle or stem) "picks with" (i.e., stays with) the fruit. When picking a blackberry fruit, the torus stays with the fruit. With a raspberry, the torus remains on the plant, leaving a hollow core in the raspberry fruit. Raspberries are grown for the fresh fruit market and for commercial processing into individually quick frozen (IQF) fruit, purée, juice, or as dried fruit used in a variety of grocery products such as raspb ...
