After solvent extraction and drying, the pure unsaponifiables are obtained in the form of a waxy solid. This waxy solid is then redissolved in untreated shea butter to increase the unsaponifiable content and thus lead to the unsaponifiable shea butter concentrate. Used in cosmetics at levels of up to 2%,it provides excellent protection against sunlight and skin dryness.Another example is the extract of the kola nut, known for its anti-irritant properties. As available in the market, it has an objectionable color and odor . At Estee Lauder, we analyzed and separated its constituents, identified the individual components with anti-irritant properties, and recombined them in the most effective ratio. In the process , objectionable color and odor were removed and possible allergens（过敏原） eliminated. All this indicates that cosmetics formulated with plant extracts today can be more effective and , at the same time, more elegant than 10 or 20 years ago. 得 分评卷人五、 Translate the following paragraph into English（共15分）采用一种简单、可靠并且有效的气相色谱法，来同时测定草药鱼腥草和鱼腥草注射液中8种活性组分的含量。在研究的浓度范围内，发现鱼腥草中草药和注射液中8种活性组分的R2的值高于0
