Solanum aculeatissimum Jacq. is a shrub considered to have valuable medicinal potential in folk medicine in China and Nepal. The fruit extract is used for toothache, scabies, headache, dandruff and lice infestation. A limited number of reports address techniques of tissue culture for this plant. Therefore, the objective of the present study was to establish the species in vitro from seeds and subsequently to compare the production of primary and secondary metabolites in the plant's leaves in situ and in vitro and in calluses obtained from leaf segments. Seedlings were established from seeds in Murashige and Skoog (MS) medium with a 50% salt concentration.The seedlings were kept under a photoperiod of 16 h of photosynthetically active radiation at 45-55 µmol m -2 s -1 provided by fluorescent bulbs. The callus induction experiment followed a completely randomized design consisting of 2 doses of kinetin (KIN), 2.5 and 10 mg L -1 , in the absence or presence of light. Segments were inoculated in glass bottles containing 50% MS medium, 30 g L -1 of sucrose, 3.5 g L -1 of agar and 1 mg L -1 of 2,4-D (2,4-dichlorophenoxyacetic acid), with the pH adjusted to 5.7±0.03. We observed that in vitro cultivation of calluses resulted in greater secondary metabolite production and accumulation, regardless of KIN concentration. In calluses, the best alternative for potentiation occurred in cultivation in the absence of light when compared to the tissues of both in situ and in vitro leaves.

“…A atividade antiulcerogênica de triterpenos pentaciclícos foi relatada por Andrade et al (2008). Uma análise estrutural e histoquímica das folhas de S. stipulaceum revelou a presença de terpenos no parênquima foliar, bem como pronunciado acúmulo destes compostos em quase todos os órgãos desta espécie, indicando uma maior diferença estrutural em relação a outras espécies do gênero (Matias et al, 2016). Alguns constituintes desse grupo, os sesquiterpenos já foram estudados como agentes protetores contra úlcera gástrica, os quais demonstraram significativa proteção contra úlceras induzidas por diferentes modelos clássicos de indução de úlcera.…”

ResumoO saber popular sobre plantas medicinais tem auxiliado estratégias de bioprospecção de espécies e direcionado o estudo para a descoberta de novas atividades farmacológicas. O objetivo desta pesquisa foi identificar espécies medicinais utilizadas contra úlcera gástrica pela comunidade do Povoado Vila Capim, Arapiraca, Alagoas e, avaliar a atividade antiulcerogênica gástrica da espécie mais saliente. Para a seleção dos informantes-chave utilizou-se a técnica da bola de neve e aplicadas entrevistas semiestruturadas. A análise das falas foi pela técnica do Discurso do Sujeito Coletivo. Para os testes farmacológicos foram utilizados ratos Wistar machos no modelo de lesão gástrica aguda induzida por etanol absoluto. A toxicidade aguda foi avaliada. Dezessete informantes-chave indicaram os sintomas e plantas medicinais utilizadas contra a úlcera gástrica. A espécie com maior valor de saliência foi a Solanum stipulaceum (sacatinga), escolhida para testes químicos e farmacológicos. O extrato aquoso bruto (SSaq) apresentou atividade significativa na dose de 200 mg kg -1 (p<0,05), sendo capaz de inibir lesões (91,35%). O extrato etanólico (SSet) demonstrou atividade gastroprotetora nas doses de 200 e 400 mg kg -1 (p<0.01), com inibição de 71,12% e 76,38%, respectivamente. É necessário aprofundar os estudos para a elucidação dos compostos químicos das folhas da espécie, toxicologia e identificação dos mecanismos de ação subjacentes à atividade gastroprotetora de S. stipulaceum.Palavras-chave: Plantas medicinais, bioprospecção, análise de saliência, ensaios in vivo. Applied ethnobotany to gastric ulcer and pharmacological evaluation of Solanum stipulaceum AbstractThe popular knowledge about medicinal plants has helped the bioprospecting strategies of species and directed to a discovery of new pharmacological activities. The aim of this study was to identify medicinal species used against gastric ulcer in the Vila Capim village, Arapiraca, Alagoas, and it evaluating a gastric anti -inflammatory activity of the most salient species. For a selection of key informants has used a snowball technique. The TCLE was signed and semi-structured interviews were applied. The analysis of the speeches was done on the Discourse of the Collective Subject technique. For pharmacological experimental tests, plant extract was underwent the Acute Gastric Lesion Model induced by absolute ethanol and using Wistar male rats. Acute toxicity was evaluated. Seventeen key informants indicated the symptoms and the medicinal plants used against gastric ulcer. The species with the highest salience value was Solanum stipulaceum Roem & Schult (sacatinga), chosen for chemical and pharmacological tests. The crude aqueous extract (SSaq) presented significant activity at a dose of 200 mg kg -1 (p<0.05), being able to inhibit lesions (91.35%). Ethanolic extract (SSet) showed gastroprotective activity at doses of 200 and 400 mg kg -1 (p <0.01), with inhibition of (71.12% and 76.38%), respectively. Further studies will be need for analysis of toxicit y and id...

“…collection, we found a resistant species identified as S. palinacanthum, which is a wild relative of eggplant distributed in South America. 18,19 This plant has been studied exclusively for its metabolites and chemical components intended for medical or pharmaceutical use, [20][21][22][23] and there are few studies of its use in agriculture, such as host resistance for phytophagous nematode control. 24 We conducted the present study to evaluate host suitability for the most important species of RKN in Japan (M. incognita, M. arenaria genotypes A2-J and A2-O, M. javanica, and M. hapla) on S. palinacanthum, and to test the effectiveness of the resistance by cultivating S. palinacanthum under field conditions infested with natural populations of RKN.…”

BACKGROUND: Root-knot nematodes (RKN, Meloidogyne spp.) are harmful phytophagous pests of Solanum spp. Some RKN species are becoming worldwide problems because of their virulence to RKN-resistant Solanum species. A new Solanum species carrying broad-spectrum resistance to Meloidogyne spp. is required for the effective management of this pest. Here we sought to determine the host suitability of RKN to Solanum palinacanthum, a wild Solanum species, and to evaluate its potential effectiveness in RKN management. RESULTS: We identified an RKN-resistant Solanum species, S. palinacanthum, by screening Solanum accessions. We tested its spectrum of resistance to common Meloidogyne spp. in Japan. In pot tests inoculated with second-stage juveniles, S. palinacanthum showed poor host suitability for Melidogyne incognita, M. arenaria genotypes A2-J and A2-O, M. javanica and M. hapla, indicating broad-spectrum resistance to RKN. The development of M. incognita within S. palinacanthum roots was significantly poorer than that in susceptible S. melongena and S. lycopersicum at 10 and 21 days after inoculation. Microplot tests confirmed that the number of second-stage juveniles in plots where S. palinacanthum grew and root galling of the root system were significantly lower than those of susceptible S. melongena, suggesting that the resistance could be used to manage RKN under field conditions. CONCLUSION: S. palinacanthum showed poor host suitability to all Meloidogyne spp. tested in this study, and it thus has the potential to be used as a genetic resource with broad-spectrum RKN resistance, and it could be effective against multiple RKN species in a field.
