Sappanone A is a homoisoflavanone that can be found in Caesalpinia sappan . [1]
Paubrasilia echinata is a species of flowering plant in the legume family, Fabaceae, that is endemic to the Atlantic Forest of Brazil. It is a Brazilian timber tree commonly known as Pernambuco wood or brazilwood and is the national tree of Brazil. This plant has a dense, orange-red heartwood that takes a high shine, and it is the premier wood used for making bows for stringed instruments. The wood also yields a historically important red dye called brazilin, which oxidizes to brazilein.
Shibori is a Japanese manual tie-dyeing technique, which produces a number of different patterns on fabric.
Biancaea sappan is a species of flowering tree in the legume family, Fabaceae, that is native to tropical Asia. Common names in English include sappanwood and Indian redwood. It was previously ascribed to the genus Caesalpinia. Sappanwood is related to brazilwood, and was itself called brasilwood in the Middle Ages.
Caesalpinia pulcherrima is a species of flowering plant in the pea family Fabaceae, native to the tropics and subtropics of the Americas. It could be native to the West Indies, but its exact origin is unknown due to widespread cultivation. Common names for this species include poinciana, peacock flower, red bird of paradise, Mexican bird of paradise, dwarf poinciana, pride of Barbados, flos pavonis, and flamboyant-de-jardin. The Hawaiian name for this plant is ʻohai aliʻi.

Tara spinosa, commonly known as tara (Quechua), also known as Peruvian carob or spiny holdback, is a small leguminous tree or thorny shrub native to Peru. T. spinosa is cultivated as a source of tannins based on a galloylated quinic acid structure. This chemical structure has been confirmed also by LC–MS. It is also grown as an ornamental plant because of its large colorful flowers and pods.
Fang is a district (amphoe) in the northern part of Chiang Mai province, northern Thailand.
Brazilin is a naturally occurring, a homoisoflavonoid, red dye obtained from the wood of Paubrasilia echinata, Biancaea sappan, Caesalpinia violacea, and Haematoxylum brasiletto. Brazilin has been used since at least the Middle Ages to dye fabric, and has been used to make paints and inks as well. The specific color produced by the pigment depends on its manner of preparation: in an acidic solution brazilin will appear yellow, but in an alkaline preparation it will appear red. Brazilin is closely related to the blue-black dye precursor hematoxylin, having one fewer hydroxyl group. Brazilein, the active dye agent, is an oxidized form of brazilin.
The Guajira–Barranquilla xeric scrub is a xeric shrubland ecoregion in Colombia, Venezuela, and the ABC Islands, covering an estimated area of 150,000 km2 (58,000 sq mi). Rainfall varies from 125 to 600 mm, and the median temperature is 26 °C (79 °F).
Ramuan is an Indonesian-Malay term referring to a blend of ingredients selected to provide health benefits in the preparation of food or the creation of herbal medicines. Ramuan may consist of leaves, stems, barks, fruits and roots, traditionally gathered from the rainforest.

Cryptophlebia ombrodelta, the litchi fruit moth or macadamia nut borer, is a moth of the family Tortricidae. The species was first described by Oswald Bertram Lower in 1898. It is native to India, Sri Lanka, Nepal, Indonesia, China, Taiwan, Vietnam, Thailand, western Malaysia, New Guinea, the Philippines, Japan, Guam, the Caroline Islands, Australia and has been introduced to Hawaii.
Ectomyelois ceratoniae, the locust bean moth, more ambiguously known as "carob moth", is a moth of the family Pyralidae. It has a nearly cosmopolitan distribution.
Dyeing is the craft of imparting colors to textiles in loose fiber, yarn, cloth or garment form by treatment with a dye. Archaeologists have found evidence of textile dyeing with natural dyes dating back to the Neolithic period. In China, dyeing with plants, barks and insects has been traced back more than 5,000 years. Natural insect dyes such as Tyrian purple and kermes and plant-based dyes such as woad, indigo and madder were important elements of the economies of Asia and Europe until the discovery of man-made synthetic dyes in the mid-19th century. Synthetic dyes quickly superseded natural dyes for the large-scale commercial textile production enabled by the Industrial Revolution, but natural dyes remained in use by traditional cultures around the world.
Fang, officially Wiang Fang Subdistrict Municipality, is a town in the northern Chiang Mai Province, Thailand, the capital of Fang District. It is 154 kilometres (96 mi) north of Chiang Mai, among the highest mountains in the country.
Homoisoflavonoids (3-benzylidenechroman-4-ones) are a type of phenolic compounds occurring naturally in plants.
Sappanol is a 3,4-dihydroxyhomoisoflavan, a type of homoisoflavonoid, that can be found in Caesalpinia sappan.
Biancaea is a genus of flowering plants in the family Fabaceae. It includes seven species, which range from Yemen to south Asia, Indochina, Malesia, China, Korea, and Japan. It belongs to the subfamily Caesalpinioideae and the tribe Caesalpinieae.
