Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

In Taiwan, Phyllodium pulchellum (L.) Desv. (Leguminosae) has been purported in folk medicine to treat fevers and liver fibrosis.  The occurrence of some amines was reported previously in this plant.  In the course of our continuing investigation of bioactive natural products from folk medicinal plants used in Taiwan, we investigated the constituents of the H2O-soluble portion of the MeOH extract of P. pulchellum.  A combination of several chromatographic techniques led to the isolation of eight compounds, including two amines N,N-dimethyltryptamine (1) and 5-methoxy-N,N-dimethyltryptamine (2); three flavonoids citrusinol (3), yukovanol (4) and katuranin (8);  two new cinnamylphenols pulchelstyrene A (5) and pulchelstyrene E (6), and Methyl protocatechuate (7).  Herein the structural characterization of these eight compounds are confirmed by the spectrums of mass and NMR. Compound 5 and 6 are the new compounds of nature product. Draconis Resina, which the colophonium　of the dragon tree has been purported in folk medicine to treat in hemostasis or catamenia ache. The occurrence of some flavans and flavonoids was reported previously in this plant. We investigated the constituents of the acetone-soluble portion of the acetone extract of Draconis Resina. A combination of several chromatographic techniques led to the isolation of five compounds, including two flavans (-)-5-methoxyflavan-7-ol (9) and (±)-5-methoxy-6-methylflavan-7-ol (10) one dracorhodin (11); one new chalcone 4,6-dihydroxy-2-methoxy-3-methyldihydrochalcone (12); and one triterpene dammaradienol (13). Herein the structural characterization of these five compounds are confirmed by the spectrums of mass and NMR. Compound 12 is the new compounds of nature product.
