ABSTRACT
Objective: To explore the pharmacological activities of volatile oil in new hybrids of Amomum villosum (Spring No.1) and compare to the female parent "Longfruit No.2". Methods: The auricle swelling model of mice was induced by xylene, the diarrhea model of mice was induced by 10% Senna, the writhing body model of mice was induced by 0.6% acetic acid solution to observe the pharmacological actions of volatile oil in "Spring No.1". Results: The volatile oil in both "Spring No.1" and "Longfruit No.2" had significant antidiarrheal effect, their effect was equivalent to the positive drug (Montmorillonite Powder). There was no significant difference in anti-inflammatory effect compared with the control group, the analgesic effect was significant. Both of them had the bidirectional regulation on gastric emptying. High dose of them had the stimulative effect in the small intestinal propulsion, and low dose of them had no significant effect. Conclusion: There is no significant difference in pharmacological activity between the new hybrid species "Spring No.1" and its female parent. It could be comparable to the traditional cultivars of A. villosum. This study provides a scientific basis for expanding A. villosum medicinal resources.
ABSTRACT
Objective: To study the identification between the Amomum villosum hybrid offspring and the female parent by useing the Fourier transform infrared (FTIR) spectroscopy. Methods: Using the FTIR to determine the infrared spectra of A.villosum hybrid offspring and female parent. Switching and processing the atlas with derivative spectrometry and Fourier self-deconvolution, to contrast for the characteristic differences in absorbance of them. Results: There were no significant differences between the A. villosum hybrid offspring and female parent by using FTIR. But 1 051.014 cm-1 was found to be the most obvious in the fourth-derivative spectrum, 771.563 4 and 1 612.432 5 cm -1 to be the most obvious in the Fourier self-deconvolution spectra. Conclusion: There are obvious differences between the A. villosum hybrid offspring and female parent in the derivative spectrometry and Fourier self-deconvolution spectroscopy atlas. Therefore, this method can be used to identify the A.villosum hybrid offspring and female parent simply, rapidly, and accurately.
ABSTRACT
Palynology, one science of plant's pollen and spores, has been proven to be a new frontier discipline. Because of the characteristics of pollen and spores, such as small size, light weight, large amount, and difficult to be found, they can leave physical evidence and provide new clues to solve a case. Therefore palynology has a good prospect for practical application in forensic medicine. The paper intends to analyze the advantage and limitation of palynology in forensic medicine by reviewing its general characteristics, classification, morphology, and disseminating circadian rhythm. We hope to provide some reference to apply palynology in forensic medicine.
