三十烷醇（TA）是由30个碳原子组成的长链脂肪醇，普遍存在于动植物的蜡质中，常用蜂蜡为原料制取。我国首先在TA剂型研究上取得重大进展，采用CD分子包衣技术研制的TA乳粉属国内外首创，它具有TA乳剂所不具备的增产效果稳定、长期贮存不变质和贮运方便等优点，并开拓TA乳粉在海藻上应用研究的新领域。TA乳粉是一种无毒害、无污染、成本低、效益高的广谱性植物生长调节剂，应用前景广阔。

Triacontanol (TA), a long chain fatty alcohol composed of 30 carbon atoms, generally exists in animal and vegetable waxes. Ordinary beewax is used as raw material for the preparation of TA. Big progress has been made in the study of TA formula. The study and preparation of TA emulsive-powder employing β- CD enclosing and linking technique is the pioneer work at home and abroad. This powdery product has some advantages that the emulsion one does not have such as stable yield increase effect, non-deterioration in long period of storage and convenience in storage and transport. Study on the application of TA emulsive-powder the application to seaweed has been carried out. TA emulsive-powder is a kind of plant growth regulator of non-toxic, non contanmination, low cost, and high effect and with wide prospect of application.
