“…As estruturas destas substâncias foram elucidadas a partir dos dados obtidos por análises espectroscópicas de RMN 1 H e 13 [20][21][22] . Análise dos espectros de RMN de 1 H e 13 C permitiram identificar a estrutura do triterpeno 2 como o ácido ursólico 23,24 .…”

“…Pesquisa bibliográfica sobre a constituição química de Styracaceae revelou a presença marcante de arilpropanóides monoméricos, lignóides [6][7][8][9][10][11][12][13][14][15] e triterpenóides [15][16][17][18] . O gênero Styrax , o mais importante da família e com maior volume de informações, caracteriza-se pelo acúmulo de norlignóides do tipo benzofurânicos, uma vez que os mesmos foram isolados em todas as espécies do gênero investigadas até o momento .…”

“…Dados fitoquímicos de espécies de Styrax registram a ocorrência de lignanas, norlignanas [6][7][8][9][10][11][12][13][14][15] e triterpenos [15][16][17][18] como constituintes predominantes no gênero. Em ensaios preliminares, visando a detecção de atividade antitumoral, o extrato bruto das folhas dessa planta apresentou atividade inibidora do crescimento de linhagens mutantes de Saccharomyces cerevisiae (Rad+, Rad 52Y e RS 321) que perderam a capacidade de regenerar o DNA.…”

Recebido em 27/11/00; aceito em 20/12/01 TRITERPENES FROM Styrax camporum (STYRACACEAE). Chemical investigation of the leaves of Styrax camporum (Styracaceae) resulted in the isolation of the lignan lariciresinol and six triterpenes: ursolic acid, 2a,3a-dihydroxy-urs-12-en-28oic acid and mixtures of uvaol and erythrodiol, as well as 3b-O-trans-p-coumaroyl-2a-hydroxy-urs-12-en-28-oic acid and 3b-Otrans-p-coumaroylmaslinic acid. The structures of these compounds were established by spectroscopic analysis. This paper deals with the first report of these compounds in S. camporum.

“…1a and 1b). As far as we know, since its characterisation by Ulubelen et al [42] in the aerial parts of S. officinalis, styraxin 42 has not been reported to occur in other Styrax species and in any other plants. Hence, styraxin 42 could represent a specific marker of S. officinalis and could be used as an indicator for the use of S. officinalis resin in an archaeological context, as attested by its identification in an 8000 years-old decorated skull [16].…”

Plant exudates have been extensively used in the past for different applications related to their olfactory, physical or medical properties. Their identification in archaeological samples relies, notably, on the characterisation of chemotaxonomic molecular markers but is often hampered by the severe alteration of their typical genuine molecular signature due to ageing. Among these exudates, those recovered from Styrax, Liquidambar and Myroxylon tree species-defined as balsams-have been exploited in the past for their pleasant scent and medical properties. They are characterized by a large variety of aromatic compounds, especially of the cinnamate and benzoate series, which can be used to assess their botanical source. These compound series may, however, be subject to alteration over time during exposure to environmental conditions in the case of archaeological material. As a result, their reliability as chemotaxonomic markers to characterise and discriminate archaeological balsams is problematic and questionable. We have, therefore, carried out a comparative analysis of various balsams (Styrax officinalis, S. paralleloneurum, S. tonkinensis, Liquidambar styraciflua, L. orientalis and M. balsamum var. pereirae) using gas chromatography-mass spectrometry to search for more reliable solid lipid markers. The results revealed that, even in the case of extended alteration/removal of cinnamic and benzoic acid derivatives, a distinction between styrax, liquidambars, Peru and Tolu balsams remains possible based on the distribution of pentacyclic triterpenes.

“…A species, Penstemon deustus, which belongs to the Family Scrophulariaceae contains a furofuranoid lignan liriodendrin which can be used as a cytotoxic agent (11). Styraxin, another a furofuran lignan, isolated from Styrax officinalis (Styraxaceae), also has antitumour activity (12). In 1989 Trumm and Eich reported that the two benzylbutyrolactones, arctigenin and trachelogenin, showed strong cytotoxic activity.…”
