What are triterpenoid glycosides?

Triterpenoid saponins are triterpenes which belong to the saponin group of compounds, making them triterpenoid glycosides. They are produced by plants as part of their self-defense mechanism with important sub-classes including ginsenosides and eleutherosides.

Which can be the best example of Monoterpenoids?

Common aliphatic examples include myrcene, citral, geraniol, lavandulol, and linalool. The important representatives of monocyclic monoterpenoids are α-terpineol, limonene, thymol, menthol, carvone, eucalyptol, and perillaldehyde.

Where are triterpenes found?

They are found in plants, microorganisms, and animals, marine organisms as well as in sedimentary rocks and oils. Several triterpenoids including ursolic and oleanolic acid, betulinic acid, celastrol, pristimerin, lupeol, and avicins have been shown to possess antitumor and antiinflammatory activities.

Is metaldehyde a molluscicide?

Metaldehyde is a potent molluscicide and is applied to land as baited-pellets. Due to its physicochemical properties, metaldehyde runs off readily from fields and enters surface water bodies where often it can be present at drinking water capitation sites at elevated concentrations.

Is used as acaricide in crops?

Acaricides are pesticides used to kill ticks and mites. Acaricides include chlorinated hydrocarbons (e.g., dichlorodiphenyltrichloroethane; DDT), organophosphorous compounds (e.g., Diazinon), carbamates (e.g., carbaryl), pyrethroids (e.g., permethrin, flumethrin), formamidines, and avermectins.

What are triterpenes used for?

Triterpenoids are used for medicinal purposes in many Asian countries for antiinflammatory, analgesic, antipyretic, hepatoprotective, cardiotonic, sedative and tonic effects (28, 33, 34).

Which is triterpenoid saponin sweetener?

Mogrosides are another group of cucurbitane-type tetracyclic triterpenoid saponins, which are mainly produced in the ripe fruit of the Chinese cucurbit, S. grosvenorii. Mogrosides are powerful and zero-caloric sweeteners and are used as a sucrose substitute for diabetic and obese patients.

What are Tetracyclic triterpenes?

Tetracyclic triterpenoids, including the dammarane, cucurbitane, cycloartane, lanostane and protostane groups, is a class of triterpenoids widely distributed in various medicinal plants, particularly those commonly used for the treatment of diabetes and its complications, such as Panax ginseng, Panax quinquefolium.

Is menthol a monoterpene?

Menthol is a cyclic monoterpene alcohol which possesses well-known cooling characteristics and a residual minty smell of the oil remnants from which it was obtained. Because of these attributes it is one of the most important flavouring additives besides vanilla and citrus.

Is camphor a monoterpene?

A cyclic monoterpene ketone that is bornane bearing an oxo substituent at position 2. A naturally occurring monoterpenoid.

What foods contain triterpenes?

A significant amount of triterpenoid saponins are found in foods such as beans, soybeans, spinach, lentils, and oats. Moreover, they may be obtained from many valuable phytomedicines, such as Radix et Rhizoma Ginseng, Radix et rhizoma glycyrrhizae, and Radix astragli [1,4,5].

What products contain metaldehyde?

Metaldehyde is a chemical that is most commonly found in slug and snail baits. Rarely, metaldehyde can also be found in solid fuels used for camp stoves. Slug and snail baits come in granular, liquid, spray, dust, pellet, meal, gel or paste forms.

What is use of metaldehyde?

Metaldehyde is a pesticide used to control snails and slugs and is approved for use in a variety of vegetable and ornamental crops in the field or greenhouse, on fruit trees, small-fruit plants, in avocado and citrus orchards, berry plants, banana plants and in limited residential areas.

Is ivermectin an acaricide?

(B.) annulatus population control has been implemented by the application of several classes of acaricides, including macrocyclic lactone (ML) derivatives such as ivermectin (IVM) [4,5].

Which of the following is used as acaricide?

What is the difference between terpenes and triterpenes?

Terpenes are simple hydrocarbons, while terpenoids are modified class of terpenes with different functional groups and oxidized methyl group moved or removed at various positions.

What are triterpenoids in plants?

Triterpenoid saponins are a diverse group of natural products in plants and are considered defensive compounds against pathogenic microbes and herbivores. Because of their various beneficial properties for humans, saponins are used in wide-ranging applications in addition to medicinally.
