Abstract: In this lab‚ the chemical components of Excedrin and Tylenol‚ two common‚ over-the-counter analgesic drugs‚ were determined by utilizing the technique of thin-layer chromatography‚ or TLC. The active ingredients of Excedrin were caffeine‚ acetaminophen‚ and aspirin with Rf values of 0.11‚ 0.38‚ and 0.61‚ respectively. The lone active ingredient of Tylenol was acetaminophen with an Rf value of 0.39. The elution sequence obtained in the experiment is as follows: ibuprofen (least polar)

Traditional way of synthesizing sensitive rhodamine starts with rhodamine B‚ amino compound‚ and some alkali additive in the presence of weak base. However‚ for RH-PY‚ the stearic hindrance of pyrene slows the reactivity‚ and the reaction does not go to completion. Therefore‚ the reaction procedure was modified as follows. First‚ HATU and DIPEA were used to activate the carboxyl group of rhodamine B‚ then the activated rhodamine B was reacted with 1-aminopyrene. By introducing this method‚ the reaction

Nutritional requirements The composition of medium for the tissue culture is the most important key factor in the successful culture of plant cells. The medium should be accurately defined of inorganic and organic chemical additives so as to provide i) the nutrients for the survival of the plant cells‚ tissues and organs under culture and ii) the optimal physical condition of pH‚ osmotic pressure‚ etc. In the culture of plant cells formulating optimum type of medium favorable for in vitro
