Mexico is considered one of the countries with the greatest diversity of the Salvia genus. A significant percentage of its species are known for their use in traditional medicine, highlighting their use as an analgesic. The objective of this work was to determine the chemical composition of the methanolic extracts of S. cinnabarina, S. lavanduloides and S. longispicata through untargeted metabolomics, as well as the in vivo evaluation of the antinociceptive effect and acute oral toxicity. The chemical profiling was performed using ultra-high performance liquid chromatography coupled with a high-resolution mass spectrometry (UPLC-ESI+/−-MS-QTOF) system and tentative identifications were performed using a compendium of information on compounds previously isolated from Mexican species of the genus. Pharmacological evaluation was carried out using the formalin test and OECD guidelines. The analysis of the spectrometric features of the mass/charge ratios of the three salvias shows that a low percentage of similarity is shared between them. Likewise, the putative identification allowed the annotation of 46 compounds, mainly of diterpene and phenolic nature, with only four compounds shared between the three species. Additionally, the extracts of the three salvias produced a significant antinociceptive effect at a dose of 300 mg/kg administered orally and did not present an acute oral toxicity effect at the maximum dose tested, indicating a parameter of LD50 > 2000 mg/kg. The exploration of the chemical profile of the three salvias by untargeted metabolomics shows that, despite being species with antinociceptive potential, they have different chemical profiles and therefore different active metabolites.

The genus Salvia (Lamiaceae) is widely distributed in Mexico with approximately 300 species. Aerial parts, leaves, and branches of sages are prepared as infusions or decoctions in traditional Mexican medicine to treat conditions such as dysentery, diarrhea, gastritis, stomach-ache, headache, sore throat, cough, bronchitis, fever, diabetes, epilepsy, nerves, insomnia, anxiety, among other ailments. The aim of this review was to compile and resume relevant information from literature regarding the chemical constituents of the pimarane and labdane type isolated from Mexican salvias and their biological activities covering the period from 1986 to 2022. A total of 31 compounds of these types were registered with 24 pimaranes and 7 labdanes. It was noticed that scientific evidence of the participation in the medicinal effects of Salvia species has not yet been reported for most of these diterpenoids. However, those described as bioactive have shown antibacterial, anticancer, anti-inflammatory, antihypotensive, antimutagenic, and antidiabetic properties. The present review provides information on the chemical and biological properties of pimaranes and labdanes from Mexican Salvia species suggesting their potential to become an option of treatment for diabetes and cancer, among other common diseases of Mexican population and of all the world. Nevertheless, further research is encouraged to demonstrate the benefits of these chemical constituents for health. 25 26 Ortiz-Mendoza, N., et al. RESUMEN El género Salvia (Lamiaceae) está ampliamente distribuido en México con aproxima-damente 300 especies. Las partes aéreas, hojas y ramas de salvias son preparadas como infusiones o decocciones y se utilizan en la medicina tradicional mexicana para tratar padecimientos como disentería, diarrea, gastritis, dolor de estómago, dolor de cabeza, dolor de garganta, tos, bronquitis, fiebre, diabetes, epilepsia, ner-vios, insomnio, ansiedad, entre otras enfermedades. El objetivo de esta revisión fue compilar y resumir información de la literatura acerca de los constituyentes químicos de tipo pimarano y labdano aislados de salvias mexicanas cubriendo el periodo de 1986 a 2022, incluyendo aquellas con actividad biológica. Un total de 31 compuestos de este tipo fueron registrados como 24 pimaranos y 7 labdanos. La evidencia de la participación de estos diterpenoides en los efectos medicinales de las especies de Salvia aún no ha sido reportada para la mayoría de estos metabolitos. Sin embargo, los que se han descrito como bioactivos demostraron presentar pro-piedades antibacterianas, anticancerígenas, antiinflamatorias, antihipotensivas, antimutagénicas y antidiabéticas. La presente revisión proporciona información sobre la importancia química y biológica de los pimaranos y labdanos de salvias mexicanas sugiriendo a estos constituyentes como posibles alternativas para el tratamiento de la diabetes y el cáncer, entre otras enfermedades que son comunes en México y en todo el mundo. No obstante, más investigación es requerida para demostrar los beneficios de estos componentes químicos para la salud.

Antecedentes y Objetivos: Durante una excursión a Atoyac de Álvarez, una región poco explorada de Guerrero, se recolectaron especímenes de Salvia con características poco comunes en taxones mexicanos. El objetivo de este trabajo es describir e ilustrar a Salvia ayecarrenoi y discutir sus afinidades morfológicas. Métodos: Se emplearon claves de identificación para determinar los ejemplares colectados a nivel de sección. Se comparó morfológicamente con los taxones de la sección Siphonantha usando bibliografía disponible, colecciones de herbarios y bases de datos. El estado de conservación de la nueva especie se determinó con base en los criterios de la IUCN. Resultados clave: Salvia ayecarrenoi es una especie endémica de Guerrero, con una combinación única de caracteres: inflorescencias hasta de 46 cm de largo, flores de color violeta, tubo ventricoso, estambres exsertos y curvados. Esta última característica es común en especies sudamericanas, pero rara en taxones mexicanos. Por lo tanto, su morfología está cercana a la sección Siphonantha, un grupo de cinco taxones de los Andes septentrionales. La nueva especie comparte algunas características morfológicas con Salvia sigchosica. Sin embargo, difiere de ella principalmente por la ausencia de guías de néctar, el tubo de la corola ventricoso, el labio inferior de la corola cuculado y la rama estigmática superior bien desarrollada y más larga que la rama inferior. De acuerdo con los criterios de la IUCN, la nueva especie está en Peligro Crítico (CR B1a). Conclusiones: Con Salvia ayecarrenoi, el número de especies mexicanas de Salvia subgénero Calosphace aumenta a 311. Las afinidades morfológicas de la nueva especie la ubican en una sección sudamericana. Sin embargo, otras secciones con distribución disyunta han resultado no monofiléticas. Por ello, es necesario reevaluar la clasificación infragenérica del grupo y los caracteres morfológicos usados para circunscribir secciones, con el objetivo de obtener agrupaciones más naturales.

Salvia semiatrata Zucc. (Lamiaceae) is endemic to Oaxaca, Mexico, and is known for its analgesic properties. Terpenoids and phenolic compounds with antinociceptive potential have been characterised from this species. The aim of this research was to determine the variation in terpenoids and flavonoids in ethyl acetate extracts of S. semiatrata collected from ten different localities, as well as to evaluate the antinociceptive effect between plants with higher and lower contents of these secondary metabolites. Quantification of S. semiatrata compounds was performed via HPLC-DAD, whereas in vivo evaluation of the antinociceptive effect was performed via formalin test. The results showed that the most abundant groups of metabolites are oleanolic acid (89.60–59.20 µg/mg), quercetin (34.81–16.28 µg/mg), catechin (11.30–9.30 µg/mg), and 7-keto-neoclerodan-3,13-dien-18,19:15,16-diolide (7-keto) (8.01–4.76 µg/mg). Principal component and canonical correspondence analysis showed that the most contrasting localities in terms of compound content and climatic variables are Miahuatlán and Santiago Huauclilla. The differences in metabolite content between the two locations did not affect the antinociceptive effects evaluated at a dose of 300 mg/kg, p.o. In conclusion, the results indicate that S. semiatrata is effective in relieving pain, regardless of the site of collection, reinforcing its traditional use as analgesic.

... Lamiaceae fascicles for some regional Flora projects have been prepared: Flora de Jalisco y Áreas Colindantes (González-Gallegos et al. 2016), Flora Fanerogámica del Valle de México (Ramamoorthy 2005), Flora Mesoamericana (Klitgaard 2012) and Flora del Valle de Tehuacán-Cuicatlán (Martínez-Gordillo et al. 2019); together these cover 51 % national diversity (González-Gallegos et al. 2021a), including update descriptions, distribution maps, photographs or illustrations and sections about phenology, habitat, distribution and diagnostic discussions. Also, 74 new species have been described within the last 40 years and remain as accepted taxa , 2021a, 2021b, Martínez-Gordillo et al. 2023, contributing with an additional 13 % of the species diversity addressed through thorough descriptions according to current standards. Hence, a significant advance in documenting the taxonomic diversity of the genus in Mexico has been achieved, though, there is still the need to complete, compile and homogenize all this information in a single publication, and there are some species poorly understood due to the scarce herbarium specimens available. ...

... Elevated temperatures alter the stomata's opening and closing mechanism, which impacts carbon uptake, creating an imbalance, and directly impacts the activity of ribulose 1,5 biphosphate carboxylase/ oxygenase [40]. Numerous plant species have shown higher amounts of terpenoids and phenolic chemicals when exposed to higher levels of luminance, although plants do experience a modest decrease in their ability to grow vegetatively and reproduce due to the displacement of carbons for the synthesis of mentioned compounds [46]. Still, the formation of these molecules is necessary to shield the plant tissues from excessive solar radiation. ...
