New terpenes fromSalvia palaestinaBenth. andSalvia syriacaL. growing wild in Jordan

Abstract

The novel seco-ursane-type triterpenoid 3β,11α-dihydroxy-17,22-seco-17(28), 12-ursadien-22-oic acid (1) was isolated for the first time from a natural source from two Salvia species growing wild in Jordan, Salvia palaestina Benth. and Salvia syrica L. In addition to compound 1, S. syriaca afforded a new sesquiterpene named syriacine (2). S. palaestina also afforded 15 other known compounds, 6 of which are isolated for the first time from the plant, and these include velutin, hyptadienic acid, cirsilineol, 2α,3β-dihydroxyurs-12-en-28-oic acid, 2α,3α-dihydroxy-24-nor-4(23),12-oleanan-28-oic acid, and 2α,3β,24-trihydroxyurs-12-en-28-oic acid. S. syriaca also afforded 16 other known compounds, 7 of which are isolated for the first time from the plant. These are 1α,3α-dihydroxyolean-9(11),12-diene, maslinic acid, 2α,3β,24-trihydroxyolean-12-en-28-oic acid, 11-oxo-oleanolic acid, 11-oxo-ursolic acid, poriferast-5-en-3,7-diol, and pectolinangenin.

Aroma Profile of Two Populations of Salvia verbenaca Collected from Two Bio‐Geographical Zones from Jordan

“…In a continuation of our work on Salvia species from Jordan, the present work aims at reporting and comparing the chemical composition of the volatile organic compounds (VOCs) in the aroma emitted spontaneously from the different aerial organs of S. verbenaca collected from two geographical zones, the Mediterranean and Irano‐Turanian. These VOCs were extracted by Head Space Solid Phase Micro‐Extraction (HS‐SPME) method and then analyzed by GC/MS.…”

Functional components, antidiabetic, anti-Alzheimer’s disease, and antioxidant activities of Salvia syriaca L.

“…Salvia syriaca is used as forage. [15] Previous phytochemical studies on S. syriaca reported the isolation of some flavonoids, [16] one sesterterpenoid salvisyriacolide, [17] a new sesquiterpene named syriacine, [18] and four novel seco-ursadiene triterpenoids [18,19] from the aerial parts of the plant. Three triterpenoids, sitosterol, and daucosterol with acetylcholinesterase inhibitory activity, [20] and some di-and triterpenoids and one flavonoid were isolated from the roots of the plant with cardiovascular activities.…”

Reticine A, a new potent natural elicitor: isolation from the fruit peel of Citrus reticulate and induction of systemic resistance against tobacco mosaic virus and other plant fungal diseases

“…Of the isolated compounds, alkaloid 7 has not been reported previously, whereas 1 , 40 2 , 41 3 , 42 4 , 43 5 , 44 6 45 and 8 46 are known compounds.…”
