RESUMEN
ObjectiveTo investigate the correlation among the botanical characteristics， biological characteristics， chemical composition， and medicinal properties and efficacy of traditional Chinese medicines （TCM） from latex-containing plants， so as to strengthen the theory of "identifying symptoms for qualities" and provide a reference for the development and utilization of the latex-containing plant resources. MethodStatistics on the meridians for properties and tastes， efficacy， medicinal parts， family and genus， and chemical components of TCM from latex-containing plants were carried out. A total of 53 TCM from latex-containing plants included in the 2020 edition of the Chinese Pharmacopoeia were screened by mining the Chinese Botanical Journal， Chinese Materia Medica， Dictionary of Traditional Chinese Medicines， and related literature. In addition， their meridians for properties and tastes， medicinal parts， chemical components， and TCM classifications were summarized and statistically analyzed by using Excel 2013 and ChiPlot 2023.3.31 software. ResultIt was found that latex-containing plants were mainly distributed in one kingdom， one phylum， two classes， and 20 families， and most of the TCM from latex-containing plants belonged to Dicotyledonaceae under Angiosperms. In terms of properties and tastes， plain>cold>warm>cool>hot and bitter>pungent>sweet>sour>salty. In terms of meridians， liver>lung>kidney>spleen=large intestine=stomach>heart>bladder=gallbladder=small intestines. In terms of medicinal parts， roots （root， rhizomes， tuberous root， and root bark）>resin>seed>whole herb （whole herb and above-ground part）>stem （stem and branch）>fruit>leaf>flower=skin. In terms of research on chemical components， they were mostly glycosides. In terms of TCM classification， they were mostly medicines for activating blood circulation and removing blood stasis. ConclusionThe TCM from latex-containing plants is mainly plain， with a uniform warm and cold distribution. The tastes are mainly bitter and pungent， and the major meridians are the liver and lung. The roots and resins are mainly used as medicines. The components mostly contain glycosides， alkaloids， and volatile oils， and most of them are medicines for activating blood circulation and removing blood stasis， as well as for removing heat and toxins. There is a certain degree of correlation among the growth habits， medicinal parts， chemical components， and the properties， tastes， and efficacy of the TCM from latex-containing plants. It may provide a reference for resource development and utilization of TCM from latex-containing plants.
RESUMEN
ObjectiveThe relevant laws among the biological characteristics， medicinal parts， growth environment， and medicinal properties and efficacy of traditional Chinese medicines （TCM） from fungi were excavated， so as to strengthen the theory of distinguishing symptoms for quality and provide a reference for the development and utilization of TCM from fungi. MethodThe medicinal parts， meridians for properties and tastes， heterotrophic mode， and efficacy of commonly used TCM from fungi were summarized. By consulting the Compendium of Materia Medica， Shennong Materia Medica， Flora of China， and literature， the TCM from fungi indexed in the 2020 edition of the Chinese Pharmacopoeia and some local pharmacopeias were checked. ResultA total of 28 common TCM from fungi were selected. Different TCMs from fungi have different meridians for properties and tastes， medicinal parts， habits， and growth environments. The relevant information was counted. Among the four properties， plain>cold>warm. Among the five tastes， sweet>bitter>light>pungent=salty. In terms of medicinal parts， fruiting body>sclerotia>complex>spermia=outer skin=other. In terms of meridians， lung>liver=heart>spleen=kidney>stomach. In terms of habits， parasitism>saprophysis>symbiosis=facultative parasitism=facultative saprophysis. ConclusionTCM from fungi are mainly parasitic and saprophytic， and the plain property and sweet taste the most. The meridians are mostly lung， heart， and liver. Nourishment and diuresis are the main efficacy. There is a certain correlation between the color， habit， medicinal parts， and growth environment of TCM from fungi and their properties， tastes， and efficacy， providing comprehensive literature reference and theoretical basis for their in-depth research， clinical use， and resource development.
RESUMEN
ObjectiveThe correlation of Pueraria lobata producing areas， climate factors， total flavonoids of P. lobata， polysaccharide content of P. lobata， and antioxidant activity of P.lobata for medicinal application was analyzed， and the relationship between climate factors and the formation of P. lobata quality was evaluated. MethodThe scavenging rates of 1,1-diphenyl-2-picrylhydrazyl radical 2,2-diphenyl-1-(2,4,6-trinitrophenyl)hydrazyl（DPPH） and 2, 2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)（ABTS） radicals by total flavonoids and polysaccharides of P. lobata were detected， and the correlation between the contents of each component and the information of producing areas and climate factors was analyzed. ResultThe ABTS+ scavenging rate by total flavonoids of P.lobata was negatively correlated with altitude （P<0.05） and positively correlated with annual sunshine hours （P<0.05）. The altitude was positively correlated with the total flavonoid content， while the annual sunshine hours were negatively correlated with the total flavonoid content. There was a negative correlation between total flavonoid content and ABTS+ scavenging rate by total flavonoids. In other words， lower altitude and longer annual sunshine hours indicated lower total flavonoid content and higher ABTS+ scavenging rate by total flavonoids. The ABTS+ scavenging rate by polysaccharides of P. lobata was negatively correlated with the frost-free period （P<0.05） and the mean temperature in July （P<0.01）. There was a positive correlation between the polysaccharide content of P. lobata and the frost-free period. The mean temperature in July was positively correlated with the polysaccharide content of P. lobata （P<0.05）. The polysaccharide content of P. lobata was negatively correlated with the ABTS+ scavenging rate by polysaccharides of P. lobata. In other words， a shorter frost-free period in the producing area and lower mean temperature in July indicated lower polysaccharide content of P. lobata and higher ABTS+ scavenging rate by polysaccharides of P. lobata. The mean temperature in July was significantly correlated with the contents of total flavonoids and polysaccharides in P. lobata samples （P<0.05）. The lower mean temperature in July was often accompanied by lower total flavonoid content of P. lobata， lower polysaccharide content of Pueraria lobata， and stronger antioxidant activity of P. lobata samples. ConclusionThe ability of P. lobata to remove ABTS+ is stronger than that of DPPH+. There is a significant correlation between climate factors， content， and antioxidant capacity in each producing area. Further research on the internal law of the formation of medicinal active components of P. lobata induced by core climate factors will provide a scientific basis for revealing the formation mechanism of genuine P. lobata and the subsequent control of P. lobata quality according to the environment of producing areas.

ObjectiveTo investigate the functions and characteristics of traditional Chinese medicine （TCM） from plant skin and their Chinese patent medicines and explore the related laws of the medicinal tissue， property， taste， efficacy， and clinical application， so as to strengthen the theory of identifying symptoms for qualities and provide references for the development and utilization of TCM from plant skin and their Chinese patent medicines. MethodBy reviewing the 2020 edition of the Chinese Pharmacopoeia and some local pharmacopeias， TCM from plant skin and their Chinese patent medicines were screened out， and the characteristics， functions， and precautions of TCM from plant skin and their Chinese patent medicines were summarized. Statistical analysis was carried out with Excel. ResultA total of 62 TCM from plant skin were found， mainly distributed in one kingdom， three phyla， and 31 families. In terms of the family genus， Rutaceae>Leguminosae>Cucurbitaceae. In terms of the medicinal tissue， bark>root bark>fruit bark>seed bark. In terms of property and taste， warm>cold>plain>cool>hot， and bitter>sweet=pungent>acidic. In terms of meridians， lung>liver>spleen>heart>colorectal>kidney>stomach=bladder. In terms of TCM classification， most of them belong to the category of heat-clearing medicines. There were 485 types of Chinese patent medicines from plant skin， with the most Chinese patent medicines containing Citri Reticulatae Pericarpium. Among the forms of administration， pills were the most predominant. In terms of the tastes of the medicines， bitter and sweet flavors predominated. In terms of functions， medicines for strengthening the body resistance were the most. For the precautions， contraindications during pregnancy were the most common. ConclusionThere is a correlation among medicinal tissue， property， taste， efficacy， and clinical application of TCM from plant skin. It is also necessary to pay attention to the contraindications of the medicines and rationally choose TCM from plant skin and their Chinese patent medicines under the guidance of TCM theory based on syndrome differentiation and treatment.
RESUMEN
ObjectiveThe relevant laws among the growth habits， habitat， medicinal site and sex， taste and efficacy of rattan derived traditional Chinese medicine（TCM） were explored to strengthen the demonstration of the quality theory and to provide theoretical basis for the clinical use and resource development of rattan. MethodThe characteristics， effects， parts， families and growth habits of some TCM from rattan were analyzed. By referring to Chinese Flora， Chinese Materia Medica， Chinese Materia Medica Dictionary and other literature， a total of 48 kinds of Rattan from Chinese medicines included in the 2020 edition of Chinese Pharmacopoeia were screened out， and their property and meridian tropism， medicinal parts， habitat and classification of TCM were statistically analyzed. Excel 2013 and SPSS Statistics 26.0 were employed for statistical research. ResultThe results of the analysis of rattan derived Chinese medicine showed that in the families and genera， Tetrandaceae > Dioscorea > Leguminoa > Cucurbitaceae > Woodtonaceae， etc. In the nature， cold > warm > flat > cool > hot； Bitter > sweet > octane > acid. In the liver meridian， liver > lung > heart > spleen > stomach = bladder = kidney > large intestine. In medicinal parts， root and rhizome > vine stem > fruit seed > flower > vascular bundle = whole grass. In terms of habitat distribution， Guangdong > Guangxi > Yunnan > Fujian > Zhejiang， et al. In the classification of TCM， dispelling wind and dampness > clearing heat > improving water and dampness > promoting blood circulation and removing blood stasis. ConclusionRattan from TCM are mainly cold in nature， bitter in flavors， and entered liver meridian， and the root and stem of Rattan are mainly used in medicine， mostly distributed in the southeast coast of China. The main effects are to channel and activate collaterals， dispel wind and dehumidification， promote blood circulation and relieve pain， clear heat and detoxify. The morphology habit， growth environment and medicinal parts of Rattan from Chinese medicine were correlated with the property and efficacy. There was a certain correlation between the growth habits， habitat and medicinal site of rattan derived Chinese medicine and its sexual and taste effect， which provided reference for the development and utilization of rattan derived Chinese medicine resources.
