編辑同志: 仙人掌(Opuntia monacancha Haw.)中含汁液甚多,基于云南农村妇女常用它来洗头的这一事实,我們試用了仙人掌来配制二二三乳剂。仙人掌屬于仙人掌科(Cadtaceae),莖扁平肥厚,汁液很多,夏天开黃赤色复瓣花,成熟后的果实可以食用。现在將我們的初步試驗的結果写在下面,这对进一步研究或可提供一点資料。試料的制备:我們試驗时所用的試料是見明近郊野生仙人掌莖。制备时,取深綠色仙人掌莖若干,剝去深綠部分,把它搗碎,以双層紗布包起,緩緩加压压出液汁,用木片將汁液刮下,然后再包入另一紗布中再压,如此反复 Editorial comrades: Opuntia monacancha Haw. contains a lot of juice. Based on the fact that Yunnan rural women used it to wash their hair, we tried cactus to formulate the two or three emulsions. The cactus belongs to the family of Cactaceae (Cadtaceae). Its stems are thick and plump, with many sap. In the summer, they bloom red and yellow petals, and ripe fruits can be eaten. Now write down the results of our preliminary experiment, which may provide some information for further study. Preparation of samples: The samples used in our experiments were wild cactus stems in the suburbs. When preparing, take a few dark green cactus stems, peel off the dark green part, chop it up, wrap it up with double layers of gauze, slowly press out the juice, scrape the juice with wood chips, and then wrap it in another gauze In the pressure, so repeated
