Oxalis pes-caprae, commonly known as African wood-sorrel, Bermuda buttercup, Bermuda sorrel, buttercup oxalis, Cape sorrel, English weed, goat's-foot, sourgrass, soursob or soursop; Afrikaans: suring; Arabic: hommayda (حميضة), [2] is a species of tristylous yellow-flowering plant in the wood sorrel family Oxalidaceae.
The compound annonacin is contained in the fruit, seeds, and leaves of soursop. [17] [18] [19] The leaves of Annona muricata contain annonamine, which is an aporphine-class alkaloid containing a quaternary ammonium group. [20] The plant also contains lichexanthone, a compound in the xanthone class. [21]
Annona montana, the mountain soursop, is a tree and its edible fruit in the Annonaceae family native to Central America, the Amazon, and islands in the Caribbean. It has fibrous fruits. [ 4 ] A. montana may be used as a rootstock for cultivated Annonas .
Annonacin is a disabling and potentially lethal neurotoxin. [4] [5] [6] Like other acetogenins, it is a mitochondrial complex I (NADH-dehydrogenase) inhibitor. [5]As NADH-dehydrogenase is responsible for the conversion of NADH to NAD+ as well as the establishment of a proton gradient in the mitochondria, annonacin disables the ability of a cell to generate ATP through oxidative phosphorylation ...
The Annonaceae are a family of flowering plants consisting of trees, shrubs, or rarely lianas [3] commonly known as the custard apple family [4] [3] or soursop family. With 108 accepted genera and about 2400 known species, [ 5 ] it is the largest family in the Magnoliales .
Several species are grown as pot plants or as ornamental plants in gardens, for example, O. versicolor. Oxalis flowers range in colour from whites to yellow, peaches, pink, or multi-coloured flowers. [11] Some varieties have double flowers, for example the double form of O. compressus.
Several annonaceous species have been found to contain acetogenins, a class of natural compounds with a wide variety of biological activities. [9] [10] The first complete genome for a species in this genus (Annona muricata) was published in 2021. [11] The earliest fossils have been found in the Lance Formation dating to the Late Cretaceous. [12]
The cherimoya (Annona cherimola), also spelled chirimoya and called chirimuya by the Quechua people, is a species of edible fruit-bearing plant in the genus Annona, from the family Annonaceae, which includes the closely related sweetsop and soursop. The plant has long been believed to be native to Ecuador and Peru, [3] with cultivation ...
