The invention belongs to the field of plant extraction, and particularly discloses a method for extracting peony fresh flower cell water from peony fresh flowers. The method includes the following steps that 1, the peony fresh flowers are picked; 2, squeezing is conducted; 3, ultrasonic rotary evaporation is conducted; 4, enzymolysis is conducted; 5, cell water juice is merged. With the picked peony fresh pedals being raw materials, a fragrance component, thermosensitive substances and other active components in the peony pedals are kept to a large degree, when the cell water is extracted, natural preservative treatment is conducted, therefore, the shelf life of the cell water is prolonged, and the pure natural activity of the cell water is improved; desensitization treatment is conductedto avoid that part of people have pollen allergy. Meanwhile, the defects are overcome that since an organic solvent is adopted for extraction, harmful substances have residues, and the organic solventneeds to be treated and recovered, environmental pollution is reduced, and energy consumption is lowered.

The invention relates to bactericidal formulations that come into contact with human body, particularly wash formulations including liquid soaps, comprising perfume ingredients active against gram-negative bacteria. Such compositions contact the target site, for example the skin surface, only for a short time, usually not longer than 30 seconds. Therefore the antibacterial action has to be of the bactericidal type and rapid. Furthermore, the bactericidal activity has to be sufficiently high to ensure an effect even when applied to wet substrates that will dilute the bactericidal formulation.

The invention relates to pills capable of adding fragrance to cigarettes. The method for preparing the pills comprises the following steps: mixing 10-20% by mass of pill wall material and 80-90% of pill cores as the pill material, making the pill material into hot-melt liquid, making the liquid into liquid drops by using drop making equipment, making the liquid drops into pills with the diameter of 1.0-3.5 mm, and adding the pills into filter tips. Since the adopted materials can effectively fix the active ingredients and can be easily eluted by smoke, the pills can gradually release the fragrance ingredient when the cigarette is sucked, so that cigarettes with different tastes can be designed according to different requirements of consumers. The pills not only can satisfy the requirements for cigarette harmful components of National Bureau but also can keep the style of the cigarettes.
