ABSTRACT
The chemical composition of the oil extracted from the seeds of Sapindus saponaria L., (Sapindaceae), was investigated. Cyanolipids constituted 5 percent hexane extract of the seeds, whereas triacylglycerols (TAG) accounted for 90 percent. The oil contains type III cyanolipids (CL) 1-cyano-2-hydroxymethylprop-1-en-3-ol-diesters. Structural investigation of the oil components was accomplished by chemical, chromatographic (TLC, CC, GC-MS), and spectroscopic (IR, NMR) means. GC-MS analysis showed that fatty acids were dominant in the CL components of the oil from S. saponaria L., with cis-11-eicosenoic acid, cis-11-octadecenoic acid and eicosanoic acid as the only esterified fatty acyl chains respectively. This being the first report of this kind of natural products (CL), located in the seeds of this plant.
La composición química del aceite de las semillas de Sapindus saponaria L., (Sapindaceae), fue investigada. Cianolípidos (CL) constituyen el 5 por ciento del extracto hexanico de las semillas, mientras que los triacilgliceroles (TAG) representaron el 90 por ciento. La fracción cianolipídica estaba compuesta por el CL tipo III, el diester de 1-ciano-2-hidroximetilprop-3-en-1-ol. La investigación estructural de los componentes del aceite se logró mediante técnicas cromatografícas, (CCF, CC, GC-MS), y espectroscópicas (IR, RMN). El análisis por GC-MS mostró que los ácidos grasos tales como: ácidos cis-11-eicosenoico, cis-11-octadecanoico y eicosanoico fueron los únicos ácidos grasos esterificados ubicados en el extracto rico en CL tipo III. Siendo este el primer reporte de esta clase de productos naturales (CL) ubicados en las semilla de esta planta.

Leishmaniasis and trypanosomiasis are parasitic diseases with a high infection rate, being a serious public health issue in the new world. Unfortunately, there are few available commercial drugs, poorly efficient and with increasing parasite resistance. Under these condi- tions, there is a need for new molecules to develop new and better drugs. One approach to carry out this search is using traditional medicine as information source to obtain new molecules or extracts to control these parasite diseases. Sapindus saponaria (Sapindaceae) fruit resin is used in Colombia to treat ulcers caused by Leishmaniasis. In a bioguided study, we have analyzed the in vitro effect of fruit resin, chroma- tographical fractions from fruit resin and also pure compounds against Leishmania species (L. panamensis, L. braziliensis, L. amazonensis and L. donovani) and Trypanosoma cruzi. The in vivo antileishmanial effect was established under the hamster model for cutaneous leish- maniasis by L. panamensis; refined extract of S. saponaria and pure saponins displayed high in vitro and in vivo activity as leishmanicides. In addition, extracts caused low viability on T. cruzi amastigotes. The use of the crude extract can be a good alternative against cutaneous leishmaniasis, due to its activity, reduced hemolytic effect, and easy production procedures.
La Leishmaniasis y la tripanosomiasis son enfermedades parasitarias con una alta incidencia, siendo un serio asunto de salud pública en el nuevo mundo. Desafortunadamente, hay pocas drogas comerciales disponibles, con pobre eficiencia y con una creciente resis- tencia parasitaria. Bajo esas condiciones, se necesitan nuevas moléculas para desarrollar nuevas y mejores drogas. Una aproximación para llevar a cabo esa búsqueda es usar la medicina tradicional como fuente de información para obtener nuevas moléculas o extractos para con- trolar esas enfermedades parasitarias. La resina de Sapindus saponaria (Sapindaceae) se usa en Colombia para tratar úlceras causadas por la Leishmaniasis. En un estudio bioguiado, se analizó el efecto in vitro de varios extractos de la resina, sus fracciones cromatográficas y algu- nos compuestos puros, contra varias especies de Leishmania (L. panamensis, L. braziliensis, L. amazonensis y L. donovani) panamensis y Trypanosoma cruzi. El efecto lesihmanicida in vivo fue establecido usando el modelo en hamster de leishmaniasis cutánea producida por L. panamensis; los extractos refinados de S. saponaria y las saponinas puras mostraron alta actividad in vitro e in vivo como leishmanicidas. Además, los extractos causaron una baja viabilidad en amastigotes de T. cruzi. El uso de extractos refinados en vez de saponinas puras podría ser una buena alternativa contra leishmaniasis cutánea debido a su actividad, poco efecto hemolítico y procedimientos de producción mucho más fáciles.

Extracts from the dried pericarp of Sapindus saponaria L. (Sapindaceae) fruits were investigated for their antifungal activity against clinical isolates of yeasts Candida albicans and C. non-albicans from vaginal secretions of women with Vulvovaginal Candidiasis. Four clinical isolates of C. albicans, a single clinical isolated of each of the species C. parapsilosis, C. glabrata, C. tropicalis, and the strain of C. albicans ATCC 90028 were used. The hydroalcoholic extract was bioactivity-directed against a clinical isolate of C. parapsilosis, and showed strong activity. The n-BuOH extract and one fraction showed strong activity against all isolates tested. Further column-chromatography on silica gel separation of this fraction afforded two pure triterpene acetylated saponins: 3-O-(4-acetyl-beta-D-xylopyranosyl)-(1->3)-alpha-Lrhamnopyranosyl-(1->2)-alpha-L-arabinopyranosyl-hederagenin (1) and 3-O-(3,4-di-acetyl-beta-D-xylopyranosyl)-(1->3)-alpha-L-rhamnopyranosyl-(1->2)-alpha-L-arabynopyranosyl-hederagenin (2). The structures of the compounds were based on spectral data (¹H and 13C NMR, HSQC, HMBC and MS), and on with literature. The saponins isolated showed strong activity against C. parapsilosis.
Extratos do pericarpo de frutos de Sapindus saponaria L. (Sapindaceae) foram testados para a atividade antifúngica sobre isolados clínicos de leveduras de Candida albicans e C. não-albicans obtidos de secreção vaginal de mulheres com Candidíase Vulvovaginal. Foram avaliados quatro isolados clínicos de C. albicans, um de cada uma das espécies C. glabrata, C. parapsilosis, C. tropicalis e uma cepa referência de C. albicans ATCC 90028. O extrato hidroalcoólico foi biomonitorado contra um isolado clínico de C. parapsilosis, apresentando forte atividade. O extrato butanólico e uma fração apresentaram forte atividade contra todos os isolados testados. Posterior análise desta fração via cromatografia em sílica gel (CHCl3:CH3OH, 1:1, v/v) resultou no isolamento de duas saponinas triterpênicas puras mono e diacetiladas, 3-O-(4-O-acetil-O-beta-D-xilopiranosil)-(1 -> 3)-alfa-L-ramnopiranosil-(1 -> 2)-alfa-L-arabinopiranosil-hederagenina (1) e 3-O-(3,4-di-O-acetil-beta-D-xilopiranosil)-(1 -> 3)-alfa-L-ramnopiranosil-(1 -> 2)-alfa-L-rabinopiranosil-hederagenina (2) respectivamente. A elucidação estrutural das substâncias foi baseada em dados espectrais (RMN de ¹H e de 13C, HSQC, HMBC, ESI/MS) e comparados com dados da literatura. As saponinas triterpênicas isoladas (1) e (2) apresentaram forte atividade contra C. parapsilosis.

Phytotherapies have offered alternative sources of therapy for migraine and gained much importance in prophylactic treatment. Sapindus trifoliatus is a medium-sized deciduous tree growing wild in south India that belongs to the family Sapindaceae. The pericarp is reported for various medicinal properties. A thick aqueous solution of the pericarp is used for the treatment of hemicrania, hysteria or epilepsy in folklore medicine. We have investigated the antihyperalgesic effects of the lyophilized aqueous extract of S. trifoliatus in animal models predictive of experimental migraine models using morphine withdrawal-induced hyperalgesia on the hot-plate test and on 0.3 percent acetic acid-induced abdominal constrictions in adult male Swiss albino mice. The extract significantly (N = 10, P < 0.05) increased the licking latency in the hot-plate test when administered ip at 10 mg/kg (6.70 ± 0.39 s in saline control vs 18.76 ± 0.96 s in S. trifoliatus-treated animals) and significantly (N = 10, P < 0.001) reduced the abdominal constrictions when administered ip at 2 and 10 mg/kg (40.20 ± 1.36 in saline control vs 30.20 ± 1.33 and 23.00 ± 0.98 for 2 and 10 mg/kg, ip, respectively, in S. trifoliatus-treated animals). Furthermore, when administered ip at 20 and 100 mg/kg, the extract significantly (N = 10, P < 0.05) inhibited the apomorphine-induced climbing behavior in mice (climbing duration 15.75 ± 5.0 min for saline control vs 11.4 ± 1.28 and 3.9 ± 1.71 min for 20 and 100 mg/kg, respectively, in S. trifoliatus-treated animals). In receptor radioligand-binding studies, the extract exhibited affinity towards D2 receptors. The findings suggest that dopamine D2 antagonism could be the mechanism involved in the antihyperalgesic activity of the aqueous extract of S. trifoliatus.
