作者之一曾报道关于檳榔粉末粗細、煎煮时間及浸出方法对于檳榔煎中醚溶性生物硷煎出效能的比較,认为制备檳榔煎都不能将檳榔中的醚溶性生物硷全部提出。中国药典(1953)对檳榔原药标准仅規定了所含醚溶性生物硷的含量下限(含醚溶性生物硷作为檳榔硷計算不得少于0.25%),而未規定其上限。一般文献中对于檳榔中醚溶性生物硷含量的記載,各有出入,如有的記載为 One of the authors has reported on the comparison of the effectiveness of the betel nut powder size, decocting time, and leaching method in the decocting efficiency of the ether-soluble bio-tackle in the betel nut decoction. It is believed that the preparation of the betel nut decoction cannot raise all the ether-soluble bio-indoles in the betel nut. The Chinese Pharmacopoeia (1953) specifies only the lower limit of the content of ether-soluble bio-derivatives contained in the raw standards of areca (including the ether-soluble bio-indole as betel nut calculation must not be less than 0.25%), and does not specify the upper limit. In the general literature, the contents of ether-soluble bifurzates in betel nuts vary from each other.
