Research progress on chemical constituents and pharmacological activities of Amomum longiligulare T.L.Wu

In order to develop and utilize the tropical medicinal resource Amomum(A.)longiligulare T.L.Wu more reasonably and effectively,this paper summarizes the research progress in chemical constituents and pharmacological activities of A.longiligulare by consulting the literatures,so as to provide a certain theoretical basis for exploring its material basis.The chemical constituents of A.longiligulare mainly include volatile oil,diphenylheptane and flavonoids,which have good efficacy in anti-peptic ulcer,as well as antioxidant,analgesic and other pharmacological activities.This paper briefly discusses the reasons for the differences in the composition of volatile oil studied by different scholars.By summarizing its pharmacological activities,it is found that its various pharmacological activities may be the basis of its anti-peptic ulcer.

Study on the chemical constituents and antitumor activity of galangal

Objective:The main chemical components of galangal(Alpinia officinarum Hance)are flavonoids and diarylheptanes.In the previous work,the total heptane and total flavonoid components of galangal were isolated.In this paper,the two components were separated.The monomeric compound was purified and its cytotoxic activity was determined.Methods:Silica gel column chromatography,ODS column chromatography,preparative thin layer chromatography,preparative and semi-preparative HPLC methods were used to separate and purify the total heptane components and total flavonoid components of galangal.Structures of compounds were identified by 1H-NMR,13C-NMR modern spectroscopic techniques combined with literature.The cytotoxic activity of the isolated compounds against MDA-MB-231(breast cancer),HepG-2(liver cancer)and MKN-45(gastric cancer)cells was tested by CCK-8 method.Results:Six compounds were isolated from the total heptane fractions of galangal,and three compounds were isolated from the total flavonoids of galangal.Their structures were identified as:5-hydroxy-7-(4-hydroxy-3-methoxyphenyl)-1-phenylheptan-3-one(1),(E)-7-(4-hydr-oxy-3-methoxyphenyl)-1-phenylhept-4-en-3-one(2),5-hydroxy-1,7-diphenylheptan-3-one(3)7-(4-hydroxyphenyl)-5-methoxy-1-phenylheptan-3-one(4),(E)-7-(4-hydroxyphenyl)-1-phenylhept-4-en-3-one(5),(E)-1,7-diphenylhept-4-en-3-one(6),pinocembrin(7),galangin(8),3-O-methylgalangin(9).Conclusion:Compounds 1-6 were isolated from the total heptane components of galangal,and compounds 7-9 were isolated from the total flavonoids of galangal.The results of CCK-8 showed that compounds 2,3,5,6,7 and 8 had weak antitumor activity.
