Cinnamon Spice obtained from the inner bark of several tree species from the genus Cinnamomum

Cinnamon is a spice obtained from the inner bark of several tree species from the genus Cinnamomum. Cinnamon is used mainly as an aromatic condiment and flavouring additive in a wide variety of cuisines, sweet and savoury dishes, breakfast cereals, snackfoods, tea and traditional foods. The aroma and flavour of cinnamon derive from its essential oil and principal component, cinnamaldehyde, as well as numerous other constituents including eugenol.

Anthracene Chemical compound

Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C14H10, consisting of three fused benzene rings. It is a component of coal tar. Anthracene is used in the production of the red dye alizarin and other dyes. Anthracene is colorless but exhibits a blue (400–500 nm peak) fluorescence under ultraviolet radiation.

<i>Cinnamomum cassia</i> Species of tree

Cinnamomum cassia, called Chinese cassia or Chinese cinnamon, is an evergreen tree originating in southern China, and widely cultivated there and elsewhere in South and Southeast Asia. It is one of several species of Cinnamomum used primarily for their aromatic bark, which is used as a spice. The buds are also used as a spice, especially in India, and were once used by the ancient Romans.

<i>Dioscorea alata</i> Species of yam

Dioscorea alata, also known as purple yam, ube, or greater yam, among many other names, is a species of yam. The tubers are usually a vivid violet-purple to bright lavender in color, but some range in color from cream to plain white. It is sometimes confused with taro and the Okinawa sweet potato, although D. alata is also grown in Okinawa where it is known as beniimo (紅芋).

<i>Cassia</i> (genus) Genus of legumes

Cassia is a genus of flowering plants in the legume family, Fabaceae, and the subfamily Caesalpinioideae. Species are known commonly as cassias. Cassia is also the English common name of some species in the genus Cinnamomum of the family Lauraceae. Species of the genera Senna and Chamaecrista were previously included in Cassia. Cassia now generally includes the largest species of the legume subtribe Cassiinae, usually mid-sized trees.

<i>Senna</i> (plant) Genus of flowering leguminous plants

Senna, the sennas, is a large genus of flowering plants in the legume family. This diverse genus is native throughout the tropics, with a small number of species in temperate regions. The number of species is estimated to be from about 260 to 350. The type species for the genus is Senna alexandrina. About 50 species of Senna are known in cultivation.

<i>Nepenthes alata</i> species of pitcher plant from the Philippines

Nepenthes alata is a tropical pitcher plant endemic to the Philippines. Like all pitcher plants, it is carnivorous and uses its nectar to attract insects that drown in the pitcher and are digested by the plant. It is highly polymorphic, and its taxonomy continues to be subject to revisions.

<i>Catopsilia pyranthe</i> Species of butterfly

Catopsilia pyranthe, the mottled emigrant, is a medium-sized butterfly of the family Pieridae found in south Asia, southeast Asia, and parts of Australia.

<i>Ulmus alata</i> Species of tree

Ulmus alata, the winged elm or wahoo, is a small- to medium-sized deciduous tree endemic to the woodlands of the southeastern and south-central United States. The species is tolerant of a wide range of soils, and of ponding, but is the least shade-tolerant of the North American elms. Its growth rate is often very slow, the trunk increasing in diameter by less than 5 mm per year. The tree is occasionally considered a nuisance as it readily invades old fields, forest clearings, and rangelands, proving particularly difficult to eradicate with herbicides.
