Their structures were elucidated on the bases of extensive NMR (&lt;sup&gt;1&lt;/sup&gt;H, &lt;sup&gt;13&lt;/sup&gt;C, DEPT, COSY, HSQC, HMBC, NOESY) and MS analysis. The antihypertensive activity of the alcoholic extract was evaluated against L-NAME&amp;ndash;induced hypertensive rats. &lt;strong&gt;Results:&lt;/strong&gt; One new monoterpene glucoside; (2R, 4S)-p-menth-1-ene- 2-O-b-D-glucopyranoside &lt;strong&gt;[1]&lt;/strong&gt; along with five known compounds; thymoquinol 2-O-b-D-glucopyranoside (zataroside-B) &lt;strong&gt;[2]&lt;/strong&gt;, quercetin 7, 3`-di-Omethylether (rhamnazin) &lt;strong&gt;[3]&lt;/strong&gt;, quercetin 7-O-methylether (rhamnetin) &lt;strong&gt;[4]&lt;/strong&gt;, quercetin 3`-O-methylether (isorhamnetin) &lt;strong&gt;[5]&lt;/strong&gt; and stigmasterol 3-Ob- D-glucopyranoside&lt;strong&gt; [6]&lt;/strong&gt; were isolated. The alcoholic extract significantly reduced the elevated SBP and partially restored the diminished nitric oxide metabolites. &lt;strong&gt;Conclusion:&lt;/strong&gt; Compound &lt;strong&gt;[1] &lt;/strong&gt;is a new and compounds &lt;strong&gt;[2-6]&lt;/strong&gt; are reported for first time from &lt;em&gt;Pulicaria jaubertii&lt;/em&gt;. The possible antihypertensive activity of the alcoholic extract may be due to its flavonoids and phenolic contents.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">80</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;El-Sayed M.
