Flavonol
Flavonols are a class of flavonoids that have the 3-hydroxyflavone backbone (IUPAC name : 3-hydroxy-2-phenylchromen-4-one). Their diversity stems from the different positions of the phenolic -OH groups. They are distinct from flavanols (with "a") such as catechin, another class of flavonoids. Flavonols are present in a wide variety of fruits and vegetables. In Western populations, estimated daily intake is in the range of 20–50 mg per day for flavonols. Individual intake varies depending on the type of diet consumed. The phenomenon of dual fluorescence (due to excited state intramolecular proton transfer or ESIPT) is induced by tautomerism of flavonols (and glucosides) and could contribute to plant UV protection and flower colour. Besides being a subclass of flavonoids, flavonols are suggested by a study of cranberry juice to play a role along with proanthocyanidins, in the juice's ability to block bacterial adhesion, demonstrated by the compressing the fimbria o ...

Rhamnose
Rhamnose (Rha, Rham) is a naturally occurring deoxy sugar. It can be classified as either a methyl- pentose or a 6-deoxy- hexose. Rhamnose predominantly occurs in nature in its L-form as L-rhamnose (6-deoxy-L- mannose). This is unusual, since most of the naturally occurring sugars are in D-form. Exceptions are the methyl pentoses L- fucose and L-rhamnose and the pentose L- arabinose. However, examples of naturally-occurring D-rhamnose include some species of bacteria, such as ''Pseudomonas aeruginosa'' and ''Helicobacter pylori''. Rhamnose can be isolated from Buckthorn (''Rhamnus''), poison sumac, and plants in the genus '' Uncaria''. Rhamnose is also produced by microalgae belonging to class Bacillariophyceae (diatoms). Rhamnose is commonly bound to other sugars in nature. It is a common glycone component of glycosides from many plants. Rhamnose is also a component of the outer cell membrane of acid-fast bacteria in the '' Mycobacterium'' genus, which includes the organi ...

Eupatorium Ligustrinum
''Ageratina ligustrina'', the (privet-leaved ageratina or privet-leaved snakeroot, is Mesoamerican species of evergreen flowering shrub in the sunflower family. It is widespread across much of Mexico and Central America from Tamaulipas to Costa Rica. ''Ageratina ligustrina'' grows to 4 metres tall, producing flat heads of daisy-like white to pink composite flower-heads in autumn. The fragrant flower-heads may be up to 20 centimeters in diameter and attract butterflies. The leaves are light green, elliptic to lance shaped, with toothed margins. Cultivation ''Ageratina ligustrina'' has been in cultivation since the mid 1800s, and in 1996, it gained the Royal Horticultural Society's Award of Garden Merit. It is not fully hardy in temperate regions. In the US, it is suitable to be grown outdoors in hardiness zones 9–11. ''A. ligustrina'' tends to be susceptible to slugs and aphids if grown outside, and whiteflies and red spider mites if grown in a greenhouse. Etymology ''Ag ...
