鹿茸片的鉴别 商品鹿茸的品名很多，质量的优劣相差也很大。一般是从色泽、质地、气味等方面加以鉴别比较。鹿茸片的形态，通常呈贺形或椭圆形，直径为1～4厘米，片极薄。外皮为红棕色。锯口面为黄白至棕黄色，外围有一明显环状骨质或无、色较深，里面具蜂窝状细孔，中间渐宽或呈空洞状，有的呈棕褐色。体轻，质硬而脆。气微腥、味咸。
Identification of the commodity name antler velvet are many quality will differ widely. Generally be identified from the comparison color, texture, smell and so on. Velvet sheet form, usually in the form He shaped or oval, 1 to 4 cm in diameter, very thin slices. Skin is reddish brown. Jukou face is yellow to brown, there is a distinct annular peripheral or without bone, dark in color, with honeycomb inside the pores, or in the middle of getting wide cavity shape, and some were brown. Light body, hard and brittle. Gas slightly fishy, salty taste.
一般来说，鹿茸片以体轻，断面蜂窝状，组织致密者为上乘品。古人对鹿茸片积累了丰富的鉴别经验。如在《增订伪药条辨》一书中所载："茸之顶尖，最首层之白如蜡，油润如脂，名之曰蜡片；次层白中兼黄，纯系血液贯注其中，故名之曰血片；最次层片有蜂窝，色紫黑透孔，名曰风片，俗云木通片，如木通之空通也。最次则骨毗连，同角相仿，名曰骨片，效力最薄矣。"由此可见其鉴别之精说，辨析之明了。在现代药材商品市场上，常把鹿茸的切片，近顶处切下的，叫做"血片"。血片厚约1毫米，呈蜜脂色，微红润，片面光滑。把在鹿茸下段切下的称做"粉片"。粉片厚约1.5毫米，呈灰白色，起粉，片面光，有细孔，周皮紫黑色，有腥气。"沙片"则临近骨端，片面粗糙，有蜂窝状细孔。血片功效甚佳，价格昂贵，粉片次之，价格也较便宜，沙片又次之。"骨片"最近骨端，质量比沙片为差。
In general, velvet with light body, honeycomb sections, dense and were for the superior product. Ancients velvet accumulated rich experience discrimination. As contained in the book "updating counterfeit drugs identified": "Velvet top, the first floor of the white as wax, such as oily fat, the name of said wax; the second layer of white and yellow, pure line blood concentrate among them, hence the name, called blood films; most times plies honeycomb, color Zihei through hole, it is called wind sheet, the saying goes, wooden tablets, such as air through the wood and most times through the adjacent bone, similar to the same angle. , it is called bone chip, the effectiveness of the thinnest men. "Thus it is said fine discrimination, discrimination of clear. In modern medicine commodity markets, often the antler slices, near the top of the cut, called "blood spots." Blood film thickness of 1 mm, was honey butter color, slightly rosy, smooth-sided. Called at the lower cut velvet "flakes." Flakes thickness of 1.5 mm, was gray, from the powder, one-sided light, fine pores, skin purple weeks, there is the smell of fish. "Sand sheet" is located near the bone ends, rough-sided, honeycomb pores. Blood sheet effect is very good, the price is expensive, flakes followed, and they are cheaper, sand sheet and followed. "Bone chip" Recently bone ends, worse than the quality of the sand sheet.
近代药物学家通过药物化学分析发现，鹿茸的顶部浸出液的生物活性最高，鹿茸的浅表组织细胞也是愈近顶部愈呈幼稚像，及至髓部顶端充满大而长的纺锤形细胞。鹿茸的基底部生物活性最低，而中间部的化学成分及含量，基本上可以代表整个鹿茸的平均值。
Modern chemical analysis of drugs by pharmaceutical scientists found that the top of the antler leachate highest biological activity, superficial tissue velvet is more near the top was more like a naive, until the top is full of pith large and long spindle cells. The base of the antler biologically active minimum, while the chemical composition and content of the intermediate portion, basically represents the average of the entire antler.
