Vacuum fractional distillation of Cunila galioides Benth. essential oil: chemical composition and biological activities of raw oil and its fractions. Nat Prod Res 2024:1-11. [PMID: 38829275 DOI: 10.1080/14786419.2024.2360149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2024] [Accepted: 05/21/2024] [Indexed: 06/05/2024]
Abstract
This work aimed to rectify Cunila galioides essential oil and evaluate the raw oil and the fractions' antifungal, allelopathic, and antioxidant activities. The results showed that the raw essential oil and the bottom fraction were primarily composed of linalyl propionate (42.9 wt.% and 60.2 wt.%). The top fraction was composed mainly of limonene (45.7 wt.%). The antioxidant activity changed with the radical and the fraction. The bottom had a weaker antifungal effect than the raw oil and the top. Nevertheless, the essential oil and the fractions had a similar antifungal activity at 0.50 % v/v and higher. Similar behavior was observed for the allelopathic tests. No difference occurred between the raw oil and the fractions, with reduced germination percentages and speed at 0.25 % v/v and complete inhibition at 0.50 % v/v. The oil can be rectified, and the fractions may be used without harming their biological activity.

Taxonomic Insights and Its Type Cyclization Correlation of Volatile Sesquiterpenes in Vitex Species and Potential Source Insecticidal Compounds: A Review. Molecules 2021; 26:molecules26216405. [PMID: 34770814 PMCID: PMC8587464 DOI: 10.3390/molecules26216405] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 10/21/2021] [Accepted: 10/22/2021] [Indexed: 11/17/2022] Open
Abstract
Sesquiterpenes (SS) are secondary metabolites formed by the bonding of 3 isoprene (C5) units. They play an important role in the defense and signaling of plants to adapt to the environment, face stress, and communicate with the outside world, and their evolutionary history is closely related to their physiological functions. This review considers their presence and extensively summarizes the 156 sesquiterpenes identified in Vitextaxa, emphasizing those with higher concentrations and frequency among species and correlating with the insecticidal activities and defensive responses reported in the literature. In addition, we classify the SS based on their chemical structures and addresses cyclization in biosynthetic origin. Most relevant sesquiterpenes of the Vitex genus are derived from the germacredienyl cation mainly via bicyclogermacrene and germacrene C, giving rise to aromadrendanes, a skeleton with the highest number of representative compounds in this genus, and 6,9-guaiadiene, respectively, indicating the production of 1.10-cyclizing sesquiterpene synthases. These enzymes can play an important role in the chemosystematics of the genus from their corresponding routes and cyclizations, constituting a new approach to chemotaxonomy. In conclusion, this review is a compilation of detailed information on the profile of sesquiterpene in the Vitex genus and, thus, points to new unexplored horizons for future research.

Moldenke in a mice experimental model. JOURNAL OF ETHNOPHARMACOLOGY 2018; 215:14-20. [PMID: 29274355 DOI: 10.1016/j.jep.2017.12.030] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2017] [Revised: 11/23/2017] [Accepted: 12/19/2017] [Indexed: 06/07/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Vitex megapotamica (Spreng.) Moldenke is a deciduous tree, native of South America. Its leaves are traditionally used to treat cardiovascular diseases. This activity is related to the presence of flavonoids, the major compounds of the crude extract. AIM OF THE STUDY This study investigated the effects of the oral administration of crude extract and standardized fractions from V. megapotamica leaves on lipid profile and on the formation of atherosclerotic plaque in C57BL/6 LDLr-KO mice treated with high-fat diet (HFD). MATERIALS AND METHODS Male C57BL/6 LDLr-KO mice were fed with HFD (cholesterol, 1.25%) for 30 days. They were treated with hydroethanolic extract (500 or 1000mg/kg/day) or fractions (125 or 250mg/kg/day). After 30 days of treatment, it was evaluated the serum lipid profile, atherogenic index, and atherosclerotic plaque. RESULTS All doses of the hydroethanolic extract reduced significantly the levels of total cholesterol, triglycerides, LDL-c and the atherogenic index. The n-butanolic fraction also reduced significantly the levels of total cholesterol, triglycerides, LDL-c and the atherogenic index, at all doses, with exception for the triglycerides, which only the lower dose was effective. The residual fraction reduced significantly the levels of total cholesterol, LDL-c and the atherogenic index, at all doses, with exception for the atherogenic index, which only the higher dose was effective. The atherosclerotic plaque formation was impaired only by the lower dose of the hydroethanolic extract. CONCLUSIONS Overall, our data suggest that V. megapotamica has potential for the treatment of dyslipidemias.

HPLC analysis of phenolics compounds and antioxidant capacity of leaves of Vitex megapotamica (Sprengel) Moldenke. Molecules 2013; 18:8342-57. [PMID: 23863774 PMCID: PMC6269793 DOI: 10.3390/molecules18078342] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2013] [Revised: 07/10/2013] [Accepted: 07/10/2013] [Indexed: 12/19/2022] Open
Abstract
Vitex megapotamica (Sprengel) Moldenke belongs to the Verbenaceae family and is popularly known as "tarumã". The antioxidant capacity of fractions and crude extract from the leaves of V. megapotamica were determined in this study through the capacity to remove reactive species and phenolic compounds were quantified in the various fractions. The IC50 (DPPH) ranged from 14.17 ± 0.76 to 37.63 ± 0.98 µg/mL. The ethyl acetate fraction might contain the strongest lipid peroxidation inhibitory compounds with an IC50 of 16.36 ± 5.09 µg/mL, being also the one with the highest content of polyphenols (522.4 ± 1.12 mg/g), flavonoids (220.48 ± 0.30 mg/g) and condensed tannins (3.86 ± 0.53 mg/g). Compounds quantified by HPLC/DAD in the crude extract and fractions were chlorogenic and rosmarinic acids. Higher dosages of the extracts were more effective in reducing levels of plasma protein carbonyls and were also shown to be able to remove reactive species by a 2',7'-dichlorofluorescein diacetate assay, reducing oxidative stress in all tested fractions. Results obtained indicated that V. megapotamica exhibits good potential to prevent diseases caused by the overproduction of free radicals and it might also be used as a potential source of natural antioxidant agents.
