[Objective] To sum up researches on components, pharmacological actions and toxicity of Polygonum multiflorum Thunb(Heshouwu). [Method] The research reference about Heshouwu in CNKI, VIP and PUBMAD database is col ected and calssified to three aspects on components, pharmacological actions and toxicity.[Result]①On components:Heshouwu contains stilbene, lecithin, anthraquinone, flavonoids, tannin and trace elements. The stilbene and anthraquinone are the mainly active components. Producing area, growth years, harvest time and processing methods are factors affecting the content of the components such as TSG in Heshouwu; Macroporous adsorption resin is the main separation method for preconcentration of TSG and anthraquinone constituents; ② On pharmacological actions and toxicity: Heshouwu has effects of hypolipidemic and liver protection, antioxidative, anti-osteoporosi, hpyerglycemic, antidepressive and antibiosis, the hypolipidemic and liver protection are the main effects which have been studied more. A reversible liver injury which displays as abnormal liver function parameter and bile metabolic disorder would be induced if the Heshouwu is administrated with a large dosage for long term. The possible components which would induce the toxicity in Heshouwu are tannin and anthraquinone, and the anthraquinone is the component with double effects of toxicity and therapy which should be considered in clinical application. [Conclusion]Reducing lipid and protecting liver is the main pharmaceutical function of the herb. As a commonly used Chinese herb for liver protection, the studies on alcoholic hepatic injury protection of Heshouwu may be a point for the researchers to focus on. The comparison studies on hypolipidemic and liver protection between Hesouwu and its processing products, and the correlations between components and pharmacological actions are worth study further.

OBJECTIVETo reveal the factors that affect the contents of volatile oil and beta-elemene in oil in Sarcandrae and to provide scientific basis for Sarcandrae's reasonable exploitation and quality assessment.

METHODA GC method was established and the contents of volatile oil and beta-elemene were determined in Sarcandrae from different length of time to grow, different medicament portions, different collection periods and different length of time to dry.

RESULTThe length of time to grow had no significant effect and the collection periods had effect on the volatile oil yield and content of beta-elemene. The volatile oil yield and content of beta-elemene were the highest in Sarcandrae harvested in December. The yield of volatile oil in different medicament portions descended in an order of roots, leaves and stems. The content of beta-elemene was the highest in leaves and the lowest in stems. With the increasing of the length of time to dry, the volatile oil yield and content of beta-elemene decreased calculated on an anhydrous basis.

CONCLUSIONThe established method is simple, accurate and repeatable. It can be used for the quality control of beta-elemene in Sarcandrae. The study provides a valuable basis for the quality assessment, the development and utilization of Sarcandrae.

The "lung and large intestine being interior-exteriorly related" is one of the classical theories in traditional Chinese medicine, which indicates a close correlation between the lung and large intestine in physiology and pathology, and plays a pivotal role in guiding the treatment of the lung and bowel diseases. Modern medicine has revealed some connections between the lung and large intestine in tissue origin and mucosal immunity, and preliminarily illuminated the material basis and possible regulatory mechanism of the theory. Recently, this theory has been applied to guide the treatment of refractory lung and intestine diseases such as COVID-19 and ulcerative colitis and has obtained reliable efficacy. Existing research results show that the anatomical homogeneity of lung and large intestine promotes the correlation between lung-bowel mucosal immunity, and mucosal immunity and migration and homing of innate lymphocytes are one of the physiological and pathological mechanisms for lung and large intestine to share. Under the guidance of this theory, Chinese medicines with heat-clearing and detoxifying or tonic effects are commonly used in the treatment of the lung and intestinal diseases by regulating lung-bowel mucosal immunity and they can be candidate drugs to treat lung/intestinal diseases simultaneously. However, the existing studies on immune regulation are mainly focused on the expression levels of sIgA and cytokines, as well as the changes in the number of immune cells such as innate lymphocytes and B lymphocytes. While the following aspects need further investigation: the airway/intestinal mucous hypersecretion, the functional changes of pulmonary and intestinal mucosal barrier immune cells, the dynamic process of lung/intestinal mucosal immune interaction, the intervention effect of local pulmonary/intestinal microecology, the correlation and biological basis between the heat-clearing and detoxifying effect and the tonic effect, and its regulation of pulmonary/intestinal mucosal immunity. In this paper, we try to analyze the internal relationship between lung and intestine related diseases from the point of view of the common mucosal immune system of lung and intestine, and summarize the characteristics and rules of traditional Chinese medicine compound and its active ingredients, which have regulatory effect on lung and intestine mucosal immune system, so as to further explain the theoretical connotation of "lung and large intestine being interior-exteriorly related" and provide reference for the research and development of drugs for related diseases.
