Its main features are: algae body as a single cell or even into a variety of groups; cell walls composed of silica and pectin, but also by the structure of the shell and the shell under the combined set of the Cheng, vertical section view was "soap-box"-shaped; in the upper and lower shell surface of the shell are patterns arranged in patterns on both sides of the main mode of symmetry and radial symmetry is divided into two categories, for the classification of the most important basis; be able to campaign Type in the shell has a shell side seam, can not be changed no shell seam types; pigment body sheet or ribbon, 1 or 2, or for multiple small discoid, yellow green or brown, containing chlorophyll a, c, also contains fucoxanthin and silicon A flavin and other photosynthetic pigments; storage material mainly for oil droplets; reproduction mainly for cell division and cell division in diatoms obvious features are: each cell division, resulting from two sub-cells,, only one and the mother cell and so big, the other one is smaller.

其主要特征是：藻体为单细胞或连成各式群体；细胞壁由硅质和果胶质组成，而且在结构上都是由上壳和下壳套合而成，纵断面观呈"肥皂盒"形；在上下壳的壳面上有花纹，花纹排列的方式主要分为两侧对称和辐射对称两大类，为分类上的最重要依据；能运动的种类在壳面都有壳缝，不能动的种类均无壳缝；色素体片状或带状，1个或2个，或为多个小盘状，黄绿色或黄褐色，含叶绿素a、c，还含有墨角藻黄素和硅甲黄素等光合色素；贮藏物质主要为油滴；繁殖方式主要为细胞分裂，硅藻的细胞分裂的明显特点是：每次细胞分裂所产生的2个子细胞中，仅有1个和母细胞等大，另1个则稍小。

The 17 of them were tentatively identified as Peonidin3-galactoside, Delphinidin3-galactoside, Cyanidin3-galactoside,Cyanidin3-glucoside,Petunidin3-galactoside ,Petunidin3-glucoside,Cyanidin3-arabinoside,Peonidin3-glucoside, Malvidin3-galactoside,Mal-vidin3-glucoside,Malvidin3-arabinoside,Petunidin3-arabinoside,Delphinidin3- glucoside,Peonidin3-(6''-acetyl)galactoside,Malvidin3-(6''-acetyl)galactoside,Peonidin3-(6''-acetyl)glucoside,Malvidin3-(6''-acetyl)glucoside.

通过制备型高效液相色谱制备2种花色苷单体，经紫外、红外、质谱、核磁共振分析鉴定，样品1主要为锦葵色素3-半乳糖苷，样品2主要为锦葵色素3-葡萄糖苷。

The green pigment in greening garlic is safe, because it has been proved by diet habitude of several thousand years.

大蒜绿变有两种形式，人们最为熟悉的是腊八蒜，这种绿色素作为腊八蒜的主要呈色物质，经过几千年的传统饮食习俗已验证其安全性，具有作为一种天然色素开发价值。

Hyperpigmentation is the result of over production of melanin, or skin pigment.

色素沉著是由於生产的黑色素，或皮肤色素。

Hyperpigmentation is askin condition that involves over production of melanin, the skin's pigment.

色素沉着是皮肤的条件，涉及到生产的黑色素，皮肤的色素。

The pigment in colored cotton fibers was extracted by methanol at room temperature. The results of color reactions HCl-Mg reaction, NaBH4 reaction, NaOH reaction, FeCl3 reaction and Pb(Ac2 reaction of the pigment extractive showed that the pigment extracted by methanol was flavone or flavonol with two adjacent hydroxide groups (Table 2, Fig. 1). The results of UV spectral analysis further proved that the pigment extracted by methanol from brown fiber belonged to flavone with two adjacent hydroxide groups in B ring, and that from the green fiber contained not only flavone but also flavonols with two adjacent hydroxide groups both in A ring and B ring and indican replaced a hydroxide group at 3-site of A ring Fig.

通过盐酸－镁粉反应、四氢硼钠还原反应、碱反应、醋酸铅反应、氯化铁反应和紫外光谱吸收的分析表明，甲醇室温提取的棕色棉纤维色素可能是黄酮类化合物，B环上带有邻二酚羟基；甲醇室温提取的绿色棉纤维色素除黄酮类化合物外，还含有3-位羟基被糖甙化的黄酮醇类化合物，A、B环上都带有邻二酚羟基。
