Acidification from leaf litter on the O-horizon is more pronounced under coniferous trees such as pine, spruce and fir, which return fewer base cations to the soil, rather than under deciduous trees; however, soil pH differences attributed to vegetation often preexisted that vegetation, and help select for species which tolerate them. Calcium ...
Betulinic acid Ber tree, white birch, winged beans, tropical carnivorous plants Triphyophyllum peltatum, Ancistrocladus heyneanus, Diospyros leucomelas a member of the persimmon family, Tetracera boiviniana, the jambul (Syzygium formosanum), chaga (Inonotus obliquus), and many other Syzygium species.
Formic acid is found naturally in insects, weeds, fruits and vegetables, and forest emissions. It appears in most ants and in stingless bees of the genus Oxytrigona. [6] [7] Wood ants from the genus Formica can spray formic acid on their prey or to defend the nest. The puss moth caterpillar (Cerura vinula) will spray it as well when threatened ...
Spinach (Spinacia oleracea) is a leafy green flowering plant native to central and Western Asia. It is of the order Caryophyllales, family Amaranthaceae, subfamily Chenopodioideae. Its leaves are a common edible vegetable consumed either fresh, or after storage using preservation techniques by canning, freezing, or dehydration.
An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO 2 OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak.
The specific epithet, aconitifolius, refers to the plant’s "Aconitum-like leaves"—coincidentally, another well-known dangerous, even deadly, genus of plants. As with most euphorbias , the entire plant contains a caustic, viscous and potentially dangerous white sap which flows readily when any part of the plant is broken, cut or damaged.
Abscisic acid (ABA) is an isoprenoid plant hormone, which is synthesized in the plastidal 2-C-methyl-D-erythritol-4-phosphate (MEP) pathway; unlike the structurally related sesquiterpenes, which are formed from the mevalonic acid-derived precursor farnesyl diphosphate (FDP), the C 15 backbone of ABA is formed after cleavage of C 40 carotenoids ...
Oleanolic acid can be found in olive oil, Phytolacca americana (American pokeweed), and Syzygium spp, garlic, etc. It was first studied and isolated from several plants, including Olea europaea [3] (leaves, fruit), Rosa woodsii (leaves), Prosopis glandulosa (leaves and twigs), Phoradendron juniperinum (whole plant), Syzygium claviflorum (leaves), Hyptis capitata (whole plant), Mirabilis jalapa ...
