Olibanum
Frankincense (also known as olibanum) is an aromatic resin used in incense and perfumes, obtained from trees of the genus ''Boswellia'' in the family Burseraceae. The word is from Old French ('high-quality incense'). There are several species of ''Boswellia'' that produce true frankincense: ''Boswellia sacra'' ( syn. ''B. bhaw-dajiana'', syn. ''B. carteri''), '' B. frereana'', '' B. serrata'' (''B. thurifera'', Indian frankincense), and '' B. papyrifera''. Resin from each is available in various grades, which depend on the time of harvesting. The resin is hand-sorted for quality. Etymology and other names The English word ''frankincense'' derives from the Old French expression , meaning 'high-quality incense'. The word in Old French meant 'noble, pure'. Although named ''frank''incense, the name is not referring to the Franks. The name of frankincense in Koine Greek (the language of the New Testament): grc-koi, λίβανος, translit=líbanos, label=none (or grc-koi, λι ...

Perfume
Perfume (, ; french: parfum) is a mixture of fragrant essential oils or aroma compounds (fragrances), fixatives and solvents, usually in liquid form, used to give the human body, animals, food, objects, and living-spaces an agreeable scent. The 1939 Nobel Laureate for Chemistry, Leopold Ružička stated in 1945 that "right from the earliest days of scientific chemistry up to the present time, perfumes have substantially contributed to the development of organic chemistry as regards methods, systematic classification, and theory." Ancient texts and archaeological excavations show the use of perfumes in some of the earliest human civilizations. Modern perfumery began in the late 19th century with the commercial synthesis of aroma compounds such as vanillin or coumarin, which allowed for the composition of perfumes with smells previously unattainable solely from natural aromatics. History The word ''perfume'' derives from the Latin ''perfumare'', meaning "to smoke through". ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boswellia Sacra
''Boswellia sacra'' (commonly known as frankincense or olibanum-tree) is a tree in the Burseraceae family. It is the primary tree in the genus ''Boswellia'' from which frankincense, a resinous dried sap, is harvested. It is native to the Arabian Peninsula (Oman, Yemen), and horn of Africa (Somalia). Description This species of ''Boswellia'' is a small deciduous tree, which reaches a height of , with one or more trunks. Its bark has the texture of paper and can be removed easily. It has compound leaves and an odd number of leaflet (botany), leaflets, which grow opposite to one another along its branches. Its tiny flowers, a yellowish white, are gathered in axillary clusters composed of five petals, ten stamens and a cup with five teeth. The fruit is a capsule (botany), capsule about long. The new leaves are covered with a fine down. Individual trees growing on steep slopes tend to develop some buttress root, buttressing that extends from the roots up into the base of the stem. T ...

Burseraceae
The Burseraceae are a moderate-sized family of 17-19 genera and about 540 species of flowering plants. The actual numbers differ according to the time period in which a given source is written describing this family. The Burseraceae are also known as the torchwood family, the frankincense and myrrh family, or simply the incense tree family. The family includes both trees and shrubs, and is native to tropical regions of Africa, Asia. Australasia, and the Americas. Just as the family size (in terms of genera and species) differs according to the time period of the study, so, too, does its placement in the higher ranks. Nevertheless, the family is a genetically supported monophyletic group currently and frequently cited within the Sapindales and is recognized as a sister group to the Anacardiaceae. The Burseraceae are characterized by the nonallergenic resin they produce in virtually all plant tissue and the distinctive smooth, yet flaking, aromatic bark.Judd, W.S., Campbell, C.S., ...

Diterpene
Diterpenes are a class of chemical compounds composed of four isoprene units, often with the molecular formula C20H32. They are biosynthesized by plants, animals and fungi via the HMG-CoA reductase pathway, with geranylgeranyl pyrophosphate being a primary intermediate. Diterpenes form the basis for biologically important compounds such as retinol, retinal, and phytol. They are known to be antimicrobial and antiinflammatory. Structures As with most terpenes a huge number of potential structures exists, which may be broadly divided according to the number of rings present. Biosynthesis Diterpenes are derived from the addition of one IPP unit to FPP to form geranylgeranyl-pyrophosphate (GGPP). From GGPP, structural diversity is achieved mainly by two classes of enzymes; the diterpene synthases and cytochromes P450. Several diterpenes are produced by plants and cyanobacteria. GGPP is also the precursor for the synthesis of the phytane by the action of the enzyme geranylger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roman Catholic Church
The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with 1.3 billion baptized Catholics worldwide . It is among the world's oldest and largest international institutions, and has played a prominent role in the history and development of Western civilization.O'Collins, p. v (preface). The church consists of 24 ''sui iuris'' churches, including the Latin Church and 23 Eastern Catholic Churches, which comprise almost 3,500 dioceses and eparchies located around the world. The pope, who is the bishop of Rome, is the chief pastor of the church. The bishopric of Rome, known as the Holy See, is the central governing authority of the church. The administrative body of the Holy See, the Roman Curia, has its principal offices in Vatican City, a small enclave of the Italian city of Rome, of which the pope is head of state. The core beliefs of Catholicism are found in the Nicene Creed. The Catholic Church teaches that it is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sesquiterpene
Sesquiterpenes are a class of terpenes that consist of three isoprene units and often have the molecular formula C15H24. Like monoterpenes, sesquiterpenes may be cyclic or contain rings, including many unique combinations. Biochemical modifications such as oxidation or rearrangement produce the related sesquiterpenoids. Sesquiterpenes are found naturally in plants and insects, as semiochemicals, e.g. defensive agents or pheromones. Biosynthesis and examples The reaction of geranyl pyrophosphate with isopentenyl pyrophosphate results in the 15-carbon farnesyl pyrophosphate (FPP), which is an intermediate in the biosynthesis of sesquiterpenes such as farnesene. Cyclic sesquiterpenes are more common than cyclic monoterpenes because of the increased chain length and additional double bond in the sesquiterpene precursors. In addition to common six-membered ring systems such as the ones found in zingiberene and bisacurone, cyclization of one end of the chain to the other end can l ...

Terpene
Terpenes () are a class of natural products consisting of compounds with the formula (C5H8)n for n > 1. Comprising more than 30,000 compounds, these unsaturated hydrocarbons are produced predominantly by plants, particularly conifers. Terpenes are further classified by the number of carbons: monoterpenes (C10), sesquiterpenes (C15), diterpenes (C20), as examples. The terpene alpha-pinene, is a major component of the common solvent, turpentine. History and terminology The term ''terpene'' was coined in 1866 by the German chemist August Kekulé to denote all hydrocarbons having the empirical formula C10H16, of which camphene was one. Previously, many hydrocarbons having the empirical formula C10H16 had been called "camphene", but many other hydrocarbons of the same composition had had different names. Kekulé coined the term "terpene" in order to reduce the confusion. The name "terpene" is a shortened form of "terpentine", an obsolete spelling of "turpentine". Although sometimes ...

Koine Greek
Koine Greek (; Koine el, ἡ κοινὴ διάλεκτος, hē koinè diálektos, the common dialect; ), also known as Hellenistic Greek, common Attic, the Alexandrian dialect, Biblical Greek or New Testament Greek, was the common supra-regional form of Greek spoken and written during the Hellenistic period, the Roman Empire and the early Byzantine Empire. It evolved from the spread of Greek following the conquests of Alexander the Great in the fourth century BC, and served as the lingua franca of much of the Mediterranean region and the Middle East during the following centuries. It was based mainly on Attic and related Ionic speech forms, with various admixtures brought about through dialect levelling with other varieties. Koine Greek included styles ranging from conservative literary forms to the spoken vernaculars of the time. As the dominant language of the Byzantine Empire, it developed further into Medieval Greek, which then turned into Modern Greek. Literary Koine ...

Classical Latin
Classical Latin is the form of Literary Latin recognized as a literary standard by writers of the late Roman Republic and early Roman Empire. It was used from 75 BC to the 3rd century AD, when it developed into Late Latin. In some later periods, it was regarded as good or proper Latin, with following versions viewed as debased, degenerate, or corrupted. The word ''Latin'' is now understood by default to mean "Classical Latin"; for example, modern Latin textbooks almost exclusively teach Classical Latin. Cicero and his contemporaries of the late republic referred to the Latin language, in contrast to other languages such as Greek, as or . They distinguished the common vernacular, however, as Vulgar Latin (''sermo vulgaris'' and ''sermo vulgi''), in contrast to the higher register that they called , sometimes translated as "Latinity". ''Latinitas'' was also called ("speech of the good families"), ''sermo urbanus'' ("speech of the city"), and in rare cases ''sermo nobilis'' ("nob ...

Article (grammar)
An article is any member of a class of dedicated words that are used with noun phrases to mark the identifiability of the referents of the noun phrases. The category of articles constitutes a part of speech. In English, both "the" and "a(n)" are articles, which combine with nouns to form noun phrases. Articles typically specify the grammatical definiteness of the noun phrase, but in many languages, they carry additional grammatical information such as gender, number, and case. Articles are part of a broader category called determiners, which also include demonstratives, possessive determiners, and quantifiers. In linguistic interlinear glossing, articles are abbreviated as . Types Definite article A definite article is an article that marks a definite noun phrase. Definite articles such as English ''the'' are used to refer to a particular member of a group. It may be something that the speaker has already mentioned or it may be otherwise something uniquely specified. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Arabia
South Arabia () is a historical region that consists of the southern region of the Arabian Peninsula in Western Asia, mainly centered in what is now the Republic of Yemen, yet it has also historically included Najran, Jizan, Al-Bahah, and 'Asir, which are presently in Saudi Arabia, and the Dhofar of present-day Oman. South Arabia is inhabited by people possessing distinctive linguistic and ethnic affinities, as well as traditions and culture, transcending recent political boundaries. There are two indigenous language groups: the now extinct Old South Arabian languages and the unrelated Modern South Arabian languages, both members of the Semitic family. Etymology The term ''Yamnat'' was mentioned in Old South Arabian inscriptions on the title of one of the kings of the second Himyarite Kingdom known as Shammar Yahrʽish II. The term was probably referring to the southwestern coastline of the Arabian peninsula and the southern coastline between Aden and Hadramout. One etymolog ...
