Ōgonkan
or are the common names for a small sized variety of Japanese citrus, whose rind is of a characteristic "golden" bright yellow color. The variety has been published as the species ''Citrus flaviculpus'' by Chōzaburō Tanaka in his 160-species scheme, but this is considered an effort of a " splitter", as opposed to Swingle's classification system which is generally preferred in the West. Alternate spellings (romanizations) include "Ougonkan" or "Ogon-kan". It has also been called "Golden orange" in Kanagawa Prefecture. History The variety has long been known in Kagoshima Prefecture as but, precise origins are unknown. According to one assertion, it has been known in Higashi-ichiki-chō ( ja) and its neighborhood (now Hioki, Kagoshima) since the Meiji Period. Anecdotally in this Hioki area, the variety is said to have been either introduced by the Jesuit Francisco de Xavier, or brought back from the Korean Peninsula during Hideyoshi's invasions of Korea in the late 16t ...

Japanese Citrus
Japanese citrus fruits were first mentioned in the ''Kojiki'' and ''Nihonshoki'', compiled in the 700s, and the ''Man'yōshū'' and ''Kokin Wakashū'', poetry anthologies compiled in the 700s and 900s, mention the Tachibana orange as a subject of ''Waka (poetry), waka'' poetry and describe its use as a medicinal, ornamental, and incense plant. Throughout their history, the Japanese have created and cultivated various varieties of citrus fruits, taking advantage of the mild climate that is ideal for growing citrus. In particular, from the 1600s during the Edo period (1603–1868) to the present, various varieties of citrus fruits have been produced, including Citrus unshiu, Unshū, :ja:ナツミカン, Natsumikan, Hassaku, Iyokan, and Dekopon. At present, Unshū is the most widely grown in Japan, and various cultivars have been developed. At present, the largest citrus growing areas are located in the Prefectures of Japan, prefectures of Wakayama Prefecture, Wakayama, Shizuoka P ...

Hyuganatsu
Hyuganatsu (''Citrus tamurana'', Japanese: 日向夏) is a citrus fruit and plant grown in Japan. The name comes from Hyūga, the ancient name of Miyazaki Prefecture in Kyushu, where the citrus is said to have originated, while means summer. Hyūganatsu grown outside Kyushu are sometimes shipped under different names such as , , or . Origin A hyūganatsu sapling was said to have been found in a Miyazaki garden sometime in the 1820s, after which it became widely cultivated throughout the region. It is theorized to be either a mutated yuzu or perhaps more likely, a chance hybrid between yuzu and pomelo. Description The fruit is of medium size and its shape is round to slightly oblong. When ripe, it turns a light yellow. Its flesh is juicy and sweet with a slightly sour taste. It is usually eaten cut up, sprinkled with sugar and with most of its rather thick pith intact. The fruit's oil is higher than other citrus fruits in trans-β-farnesene, l-carvone, and has a higher ...

Mikan
''Citrus unshiu'' is a semi-seedless and easy-peeling citrus species, also known as the satsuma mandarin or Japanese mandarin. During the Edo period of Japan, kishu mikans were more popular because there was a popular superstition that eating ''Citrus unshiu'' without seeds made people prone to infertility. ''Citrus unshiu'' became popular in Japan after modernization started in the Meiji period. It was introduced to the West from the Satsuma region of Japan in 1878. ''Citrus unshiu'' was named after Unshu (Wenzhou), a famous production area of ''Citrus'' species in China, in the late Edo period of Japan. Before the name ''unshu mikan'' was established in Japan, it was called ''nakajima mikain'' or ''nagashima mikan'' after the place name of Nishi-Nakajima in Amakusa District of the Higo Province (later Nagashima, Kagoshima), where the species is said to have been born. There are two theories about the origin of the ''Citrus unshiu''. One is that ''Citrus unshiu'' originated ...

Monoterpene
Monoterpenes are a class of terpenes that consist of two isoprene units and have the molecular formula C10H16. Monoterpenes may be linear (acyclic) or contain rings (monocyclic and bicyclic). Modified terpenes, such as those containing oxygen functionality or missing a methyl group, are called monoterpenoids. Monoterpenes and monoterpenoids are diverse. They have relevance to the pharmaceutical, cosmetic, agricultural, and food industries. Biosynthesis Monoterpenes are derived biosynthetically from units of isopentenyl pyrophosphate, which is formed from acetyl-CoA via the intermediacy of mevalonic acid in the HMG-CoA reductase pathway. An alternative, unrelated biosynthesis pathway of IPP is known in some bacterial groups and the plastids of plants, the so-called MEP-(2-methyl-D-erythritol-4-phosphate) pathway, which is initiated from C5 sugars. In both pathways, IPP is isomerized to DMAPP by the enzyme isopentenyl pyrophosphate isomerase. Geranyl pyrophosphate is the precu ...
