还有,又是称番红花为郁金——

番红花 番红花

Stigma Croci

(英)Saffron

别名 西红花、藏红花。

来源 为鸢尾科植物番红花Crocus sativus L.的柱头。

植物形态 多年生草本。鳞茎扁球形,大小不一,直径0.5~10cm,外被褐色膜质鳞叶。自鳞茎生出2~14株丛,每丛有叶2~13片,基部为3~5片广阔鳞片乌黑叶线形,长15~35cm,宽2~4mm,边缘反卷,具细毛。花顶生;花被片6,倒卵圆形,淡紫色,花筒细管状;雄蕊3,花药基部箭形;子房下位,3室,花柱细长,黄色,柱头3,膨大呈漏斗状,伸出花被筒外而下垂,深红色。蒴果长圆形,具三钝棱。种子多数,球形。花期10~11月。

鸢尾科(Iridaceae)具鳞茎的多年生植物,学名为Crocus sativus。其辛辣的金色柱头很名贵,用于食品调味和上色,又用作染料。《圣经?雅歌》第4章第14节中提到一些香草时包括番红花。带有强烈的独特香气和苦味。在地中海地区和东方菜肴以及英国、斯堪的那维亚和巴尔干的面包中作调色和调味佐料。也是法式菜浓味炖鱼的重要成分。古代印度蒸馏番红花柱头得到一种金色水溶性布匹染料。在释迦牟尼去世后,其弟子以番红花为他们法衣的正式颜色。在几种文化中,王室服装均用这种染料染色。在希腊和罗马,番红花作为香料撒在会堂、宫廷、剧场和浴室。番红花与古希腊的艺妓关系密切。尼禄回罗马时,街道上洒满番红花。

一般认为番红花原产於地中海地区、小亚细亚和伊朗。在伊朗和喀什米尔有栽种,并认为由蒙古远征军传入中国。曾记载於中国的《本草纲目》(1552~1578)。早期主要栽培中心是西利西亚和小亚细亚。约961年阿拉伯人将其栽种於西班牙。10世纪一本英格兰医书中有记载。但可能后来在西欧消失,直至十字军又将其重新引入,在许多时期,番红花贵於同重量的黄金,今天仍是世界上最贵重的香料。现主要种植於西班牙、法国、西西里岛、义大利亚平宁山脉以及伊朗和喀什米尔。从花中采摘三个柱头,摊放於托盘。用炭火烤乾便可用於食品调味和调色。0.45公斤(1磅)番红花即来自75,000朵花。为世界上最贵重的香料。香精油含量0.5~1%,主要成分是苦藏花素(C16H26O7)。著色物质为藏花素(C44H64O26?H2O)。

北京、上海、浙江、江苏等地有引种栽培。

采制 10~11月中下旬,晴天早晨采花,于室内摘取柱头,晒干或低温烘干。

性状 柱头线形,长约3cm,暗红色,上部较宽而略扁平,顶端边缘具不整齐的齿状,下端有的残留一小段黄色花柱。体轻,质松软,无油润光泽,干燥后质脆易断。气特异微有刺激性,味微苦。

化学成分 含番红花甙-1,2,3,4(crocin-1~4)、番红花苦甙(picrocrocin)、番红花酸二甲酯(crocetin dimethyl ester)、α-番红花酸(a-crocetin)番红花醛(safranal)、挥发油等。

栀子黄是什么食品添加剂?

藏花素(Crocin),又称栀子黄,是一种在番红花和栀子中发现的类胡萝卜素类天然色素,是由龙胆二糖和藏花酸形成的酯化物。熔点186℃,结晶体为深红色,在水溶液中显橘黄色。

近年来,随着现代医学药学以及分子生物学技术的飞速发展,发现藏红花除了在保护神经系统以及抗心血管系统疾病等方面有良好功效外,在抗肿瘤方面也有功效。藏花素最早用于作为红色染色剂,且具有抗氧化、抗抑郁和抗癌活性,最新的研究发现它还具有壮阳的功效。

具有抗癌、抑制肿瘤、 降血脂、护肝、淬灭自由基、抗氧化等作用,还具有水溶性好、着色力强、对光温稳定、pH1~ 14范围内均呈鲜艳的黄色等优点中,而被广泛地应用于食品领域,日本年需要量320吨,居日本天然色素市场第四位。

我国分别于1987年、1998 年颁布实施了食品添加剂-栀子黄、食品中栀子黄的测定的国家标准,标准中以色价作为栀子黄质量评价和控制的指标, 以薄层色谱的Rf值作为栀子黄色素定性的依据,但还缺乏有效的栀子黄即藏花素的定量标准。

生理学的作用

藏红花的主要活性成分是黄色色素藏红花素 2(已知具有不同糖基化的其他三种衍生物),在分子的每一端都含有龙胆二糖(二糖)基团。藏红花的五种主要生物活性成分,即四种藏红花素和藏红花素,可以用 HPLC-UV 测定。

藏红花素可减轻乙醇对学习功能造成的部分损害,并防止乙醇抑制海马体的长时程增强 (LTP)。这是一种依赖于活动的突触可塑性,是学习和记忆的基础。相关的中枢神经系统效应是二苯硫代二糖酯特有的。

Crocetin Glucose Genthiobiose 的强度只有一半,而二葡萄糖酯则完全无效。

Saffron

Description

Saffron is a herbal preparation harvested from the stigma of the Crocus sativus flower. It is dark orange and threadlike in appearance, with a spicy flavor and pungent odor. The plant is grown in India, Spain, France, Italy, the Middle East, and the eastern Mediterranean region.

General Use

In addition to its culinary uses, saffron is prescribed as a herbal remedy to stimulate the digestive system, ease colic and stomach discomfort, and minimize gas. It is also used as an emmenagogue, to stimulate and promote menstrual flow in women.

Preliminary studies have shown that saffron may also be a useful tool in fighting cancer. According to a 1999 study, use of the herb slowed tumor growth and extended lifespan in female rats. A 2002 study done at Indiana University indicates that saffron may not only be effective in treating certain types of cancer, but significantly less likely to cause birth defects if given to pregnant women than all-trans-retinoic acid (ATRA), the compound most often given to treat these cancers. Saffron may thus be a preferable alternative to treating ATRA-sensitive cancers in women of childbearing age.

Additional human studies have indicated that saffron has powerful antioxidant properties; that is, it helps to protect living tissues from free radicals and other harmful effects of oxidation.

Two chemical components of saffron extract, crocetin and crocin, reportedly improved memory and learning skills in learning-impaired rats in a Japanese study published in early 2000. These properties indicate that saffron extract may be a useful treatment for neurodegenerative disorders and related memory impairment.

2.关于薰衣草:英文名字lavender

Any of various aromatic Old World plants of the genus Lavandula, especially L. angustifolia, having clusters of small purplish flowers that yield an oil used in perfumery. 熏衣草:任一种产于欧洲的熏衣草 属芳香植物,尤指 狭叶熏衣草 ,开成串的紫色小花,其香精油可用于制香水。

Lavender

Description

Lavender is a hardy perennial in the Lamiaciae, or mint, family. The herb is a Mediterranean native. There are many species of lavendula which vary somewhat in appearance and aromatic quality. English lavender, L. augustifolia, also known as true lavender, is commercially valuable in the perfume industry and is a mainstay of English country gardens. French lavender, L.stoechas, is the species most probably used in Roman times as a scenting agent in washing water. The species L. officinalis is the official species used in medicinal preparations, though all lavenders have medicinal properties in varying degrees.

This fragrant, bushy shrub has been widely cultivated for its essential oil. The tiny, tubular, mauve-blue blossoms grow in whorls of six to ten flowers along square, angular stems and form a terminal spike. These flower spikes stretch upward beyond the 12-18 inch (3.6-5.4 m) height of the shrub, blooming from June to August. The blossoms are well liked by bees and a good source of honey. The needle-like, evergreen, downy leaves are a light, silver-gray. They are lanceolate, opposite, and sessile, and grow from a branched stem. The bark is gray and flaky. The herb thrives in full sun and poor soil. Ancient Greeks and Romans used lavender blossoms to scent bath water, a common use that gave the herb its name, derived from the Latin lavare, meaning to wash.

General Use

Lavender is best known and loved for its fragrance. The herb has been used since ancient times in perfumery. As an aromatic plant, lavender lifts the spirits and chases melancholy. Taking just a few whiffs of this sweet-smelling herb is said to dispel dizziness. Traditionally, women in labor clutched sprigs of lavender to bring added courage and strength to the task of childbearing. A decoction of the flower may be used as a feminine douche for leucorrhoea. The dried blossoms, sewn into sachets, may be used to repel moths and to scent clothing, or may be lit like incense to scent a room. Because of its fumigant properties, the herb was hung in the home to repel flies and mosquitoes, and strewn about to sanitize the floors. Lavender essential oil was a component of smelling salts in Victorian times.

The essential oil of certain lavender species has a sedative, antispasmodic, and tranquilizing effect. Lavender has been long valued as a headache remedy. It can be taken in a mild infusion, or can be rubbed on the temples, or sniffed like smelling salts to provide relief from headaches caused by stress. Lavender oil is antiseptic, and has been used as a topical disinfectant for wounds. In high doses, it can kill many common bacteria such as typhoid, diphtheria, streptococcus, and pneumococcus, according to some research. The essential oil has also been used as a folk treatment for the bite of some venomous snakes. When used in hydrotherapy as part of an aromatic, Epsom salt bath, the essential oils of some species will soothe tired nerves and relieve the pain of neuralgia. They are also used topically on burns and have been shown to speed healing. It is also a fine addition to a foot bath for sore feet. Lavender essence makes a pleasant massage oil for kneading sore muscles and joints. Acting internally, lavender's chemical properties increase the flow of bile into the intestines, relieving indigestion. Its carminative properties help expel intestinal gas. Lavender is an adjuvant and may be used in combination with other herbs to make a tonic cordial to strengthen the nervous system.

A 2002 report from Korea showed that aromatherapy massage with lavender oil and tea tree oil on patients undergoing hemodialysis for kidney failure received relief from the itching the treatment often causes.
