(-)-Myrtenol, Propanoic acid, 2-methyl-, 3-hydroxy-2,4,4-trimethylpentyl ester, 1,4-Cyclohexadiene-1-methanol, 4-(1-methylethyl)-, 1,3-Cyclohexadiene-1-methanol, 4-(1-methylethyl)-, Ethyl (2E)-3-(4-hydroxy-3-methoxyphenyl)-2-propenoate, 4-((1E)-3-Hydroxy-1-propenyl)-2-methoxyphenol, n-Amyl ether, o-Methoxy-\(\alpha\),\(\alpha\)-dimethyl benzyl alcohol, 2-Furanmethanol, 5-ethenyltetrahydrofuran-\(\alpha\),\(\alpha\),5-trimethyl-, and cis-, 2-Furancarboxylic acid were not found. Oxygenated monoterepenes and monoterepene hydrocarbon compounds play a crucial role in biological and medical applications. It is also known that monoterepenes and their derivatives exhibit anti-inflammatory, antimicrobial, anticonvulsant, analgesic, antiviral, antitumor, Antituberculosis, and antioxidant biological activities [35]. The chromatogram of _S. eversii_'s flowering aerial part (Figure 5) shows high peaks with the retention times (minutes) of compounds such as Bicyclo[3,1,1]hept-2-ene-2-methanol, 6,6-dimethyl- (5.95%)--16.3 min; 4H-Pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl

(5,26%)--25.0 min; Benzofuran, 2,3-dihydro- (14.77%)--27.5 min; 9,12,15-Octadecatrienoic acid, ethyl ester, (Z,Z,Z)- (9.41%)--31.1 min; Phytol (8.98%)--31.6 min; and Ethyl \(\alpha\)-d-glucopyranoside (22.04%)--42.9 min. Depending on their skeletal core, diterpenes can be categorized as linear, bicyclic, tricyclic or tetracyclic, pentacyclic, and macrocyclic [36]. Of the diterpenes found in this plant, Phytol, which is present in the root (aerial part) at 1.56%, at 5.56% in the leaf and stem, and 8.98% in the flowering aerial part, in the root (underground part), was not found. Natural diterpenes have a variety of biological effects, including anti-inflammatory, antibacterial, and antispasmodic effects [37]. Numerous diterpenes have demonstrated significant effects on the cardiovascular system. They include marrubenol, which inhibits smooth muscle contraction by blocking L-type calcium channels; eleganolone and 14-deoxyandrographolide, which exhibit vasrelaxant qualities; and grayanotoxin I, which elicits positive inotropic responses [38]. Two hydrocarbon substituents joined to a carbonyl atom form a ketone. The body produces ketones when cells do not receive enough glucose, which is the body's main energy source. Blood or urine can contain ketones, and elevated levels of these compounds may signify ketoacidosis [39]. Ketones were found in varying amounts across different parts of _S. eversii_. In the root (underground part), ketones were present at a level of 6.72%, with notable compounds including 4-Cyclopentene-1,3-dione (0.78%), 2-Cyclopenten-1-one, 2-hydroxy-(1.16%), 2,5-Dimethyl-4-hydroxy-3(2H)-furanone (0.43%), 1,3-Dioxol-2-one,4,5-dimethyl-(2.44%), and 4H-Pyman-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl-(1.91%). 4-(p-Acetoxy phenyl)-2-butanone was not found. In the root (aerial part), ketones were more abundant at 13.54%, featuring similar compounds but with differing concentrations: 4-Cyclopentene-1,3-dione (1.34%), 2-Cyclopenten-1-one, 2-hydroxy- (2.23%), 2,5-Dimethyl-4-hydroxy-3(2H)-furanone (0.65%), 1,3-Dioxol-2-one,4,5-dimethyl- (5.66%), and 4H-Pyman-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl- (3.66%). 4-(p-Acetoxy phenyl)-2-butanone was not detected. Similarly, in the leaf and stem, ketones were present at 13.57%, with notable compounds such as 4-Cyclopentene-1,3-dione (0.94%), 2,Cyclopenten-1-one, 2-hydroxy-(1.48%), 2,5-Dimethyl-4-hydroxy-3(2H)-furanone (1.07%), 1,3-Dioxol-2-one,4,5-dimethyl-(5.13%), and 4H-Pyman-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl- (4.95%). 4-(p-Acetoxy phenyl)-2-butanone was not found.
