Cryptomeria is a monotypic genus of conifer in the cypress family Cupressaceae, formerly belonging to the family Taxodiaceae. It includes only one species, Cryptomeria japonica. It used to be considered by some to be endemic to Japan, where it is known as Sugi. The tree is called Japanese cedar or Japanese redwood in English. It has been extensively introduced and cultivated for wood production on the Azores.
Lonicera japonica, known as Japanese honeysuckle and golden-and-silver honeysuckle, is a species of honeysuckle native to eastern Asia, including many parts of China. It is often grown as an ornamental plant, but has become an invasive species in a number of countries. Japanese honeysuckle is used in traditional Chinese medicine.
Lespedeza is a genus of some 45 species of flowering plants in the pea family (Fabaceae), commonly known as bush clovers or Japanese clovers (hagi). The genus is native to warm temperate to subtropical regions of eastern North America, eastern and southern Asia and Australasia.
Coptis is a genus of between 10–15 species of flowering plants in the family Ranunculaceae, native to Asia and North America.
Scopolia is a genus of four species of flowering plants in the family Solanaceae, native to Europe and Asia. The genus is named after Giovanni Scopoli (1723–88), a Tyrolean naturalist. The genus has a disjunct distribution, with two recognised species in Central to Eastern Europe,, and two species in East Asia. The two European species are:
Coptis trifolia, commonly known as the threeleaf goldthread or savoyane, is a perennial plant in the genus Coptis, a member of the family Ranunculaceae.
Coptis chinensis, the Chinese goldthread, is a species of goldthread flowering plant native to China.
In enzymology, a secologanin synthase (EC 1.14.19.62, was wrongly classified as EC 1.3.3.9 in the past) is an enzyme that catalyzes the chemical reaction
(S)-Tetrahydroberberine oxidase is an enzyme that catalyzes the final transformation in the biosynthesis of berberine, a quaternary benzylisoquinoline alkaloid of the protoberberine structural subgroup. This reaction pathway catalyzes the four-electron oxidation of (S)-tetrahydroberberine in the presence of oxygen to produce berberine and hydrogen peroxide as products.
Phellodendrine is an alkaloid isolated originally from Phellodendron amurense (Rutaceae).
Palmatine is a protoberberine alkaloid found in several plants including Phellodendron amurense, Coptis Chinensis and Corydalis yanhusuo, Tinospora cordifolia, Tinospora sagittata, Phellodendron amurense, Stephania yunnanensis.
Scopolia japonica, also Japanese belladonna or Korean scopolia, is a flowering plant species in the genus Scopolia - one of the eight genera in tribe Hyoscyameae of the nightshade family Solanaceae.
The flora of Japan comprises a large assemblage of plant species which can be found in Japan, such as sakura, katsura, momiji and azalea. There are many species which are endemic to Japan.
Ophiorrhiza is a genus of flowering plants in the coffee family (Rubiaceae). Species of the genus contain camptothecin, an alkaloid used to make chemotherapeutic agents. So many of Ophiorrhiza species are endemic to certain areas of western Ghats. Species include:
Stephania japonica, known as snake vine, is a vine often seen in sheltered areas near the sea.
Nuphar japonica, known as East Asian yellow water-lily, is an aquatic plant species in the genus Nuphar found in Japan and the Korean Peninsula. It is endangered in Russia. The species was not accepted by The Plant List as of November 2013, which regarded it as an "unresolved name".
Orixa japonica, commonly called East Asian orixa or Japanese orixa, is a deciduous shrub growing to 3 metres (10 ft) with an equal spread. Native to Japan and South Korea, it is found on forested, sunny slopes at elevations from 500 to 1300 m. A recent scientific study found this plant to contain previously unknown alkaloids that may be effective against Plasmodium falciparum, one of the protozoan species that cause human malaria.
(S)-Magnoflorine is a quaternary benzylisoquinoline alkaloid (BIA) of the aporphine structural subgroup which has been isolated from various species of the family Menispermaceae, such as Pachygone ovata,Sinomenium acutum, and Cissampelos pareira.
Skimmianine is a furoquinoline alkaloid found in Skimmia japonica, a flowering plant in family Rutaceae that is native to Japan and China. It is also a strong acetylcholinesterase (AChE) inhibitor.
(S)-corytuberine synthase is a cytochrome P450 enzyme purified from the plant Coptis japonica, with EC number EC 1.14.19.51 and CYP Symbol CYP80G2, and catalyses an intramolecular C-C phenol coupling of (S)-reticuline in magnoflorine biosynthesis.
