Quercitron is a yellow natural dye obtained from the bark of the Eastern Black Oak, a forest tree indigenous in North America. It was formerly called Dutch pink, English pink, or Italian pink.
Phyllostachys nigra, commonly known as black bamboo or purple bamboo, is a species of bamboo, native to Hunan Province of China, and is widely cultivated elsewhere.
Apigenin (4′,5,7-trihydroxyflavone), found in many plants, is a natural product belonging to the flavone class that is the aglycone of several naturally occurring glycosides. It is a yellow crystalline solid that has been used to dye wool.
Flavones are a class of flavonoids based on the backbone of 2-phenylchromen-4-one (2-phenyl-1-benzopyran-4-one).
Flavonoids are synthesized by the phenylpropanoid metabolic pathway in which the amino acid phenylalanine is used to produce 4-coumaroyl-CoA. This can be combined with malonyl-CoA to yield the true backbone of flavonoids, a group of compounds called chalcones, which contain two phenyl rings. Conjugate ring-closure of chalcones results in the familiar form of flavonoids, the three-ringed structure of a flavone. The metabolic pathway continues through a series of enzymatic modifications to yield flavanones → dihydroflavonols → anthocyanins. Along this pathway, many products can be formed, including the flavonols, flavan-3-ols, proanthocyanidins (tannins) and a host of other various polyphenolics.

Tricin is a chemical compound. It is an O-methylated flavone, a type of flavonoid. It can be found in rice bran and sugarcane.
Vitexin is an apigenin flavone glucoside, a chemical compound found in the passion flower, Vitex agnus-castus, in the Phyllostachys nigra bamboo leaves, in the pearl millet, and in Hawthorn.
The molecular formula C21H20O10 (molar mass: 432.38 g/mol, exact mass: 432.105647 u) may refer to:
Apiin is a natural flavonoid, a diglycoside of the flavone apigenin found in the winter-hardy plants parsley and celery, and in banana leaf. The glycoside moiety at carbon-7 of apigenin, O-β-D-apiofuranosyl(→)2-β-D-glucosyl, is carried by several other flavones in parsley plant and seed. The sugar apiose possibly play a role in winter hardiness of celery, duckweed and parsley.
Phyllostachys edulis, the mōsō bamboo, or tortoise-shell bamboo, or mao zhu, , is a temperate species of giant timber bamboo native to China and Taiwan and naturalised elsewhere, including Japan where it is widely distributed from south of Hokkaido to Kagoshima. The edulis part of the Latin name refers to its edible shoots. This bamboo can reach heights of up to 28 m (92 ft). This particular species of bamboo is the most common species used in the bamboo textile industry of China and other countries, for the production of rayon. Moso is less cold-hardy than many phyllostachys, surviving at a reduced height down to 5 degrees Fahrenheit (-15 °C).
Apiose is a branched-chain sugar found as residues in galacturonans-type pectins; that occurs in parsley and many other plants. Apiose is a component of cell wall polysaccharides.
Acacetin is a 4′-O-methylated flavone of the parent compound apigenin, found in Robinia pseudoacacia, Turnera diffusa (damiana), Betula pendula, and in the fern Asplenium normale.
Cunninghamella elegans is a species of fungus in the genus Cunninghamella found in soil.
Echinops echinatus, the Indian globe thistle, commonly known as Usnakantaka, is a species of globe thistle, found in India, Pakistan, and Sri Lanka. Indian globe thistle is an erect branched herb about 100 cm high. It has short, stout stems, branching from the base, covered with white cottony hair. Alternately arranged oblong, deeply pinnatifid leaves are 7–12 cm long. Flower heads occur in solitary white spherical balls, 3–5 cm across. Petals of the tiny white disc florets are 5 mm long. Flowers are surrounded by straight, strong, white bristles. Often misidentified with Silybum marianum (L.) Gaertner, it is colloquially known as Camel's thistle.
Teucrium gnaphalodes is a plant species in the genus Teucrium. It is endemic to the Iberian Peninsula and grows at altitudes between 200 and 1500 m. It flowers from March to July.
Silene jenisseensis, is a species of flowering plant in the family Caryophyllaceae, native to Siberia, Far East and Mongolia.
