A B S T R A C TThis study describes the antioxidant, antibacterial activities of five different solvents [methanol, aqueous ethanol (ethanol-water, 70:30, v/v), acetone, ethyl acetate and water extracts of Passiflora wilsonii Hemsl. The results obtained in this study have considerable value with respect to various solvent extracts from Passiflora wilsonii Hemsl., showed varying degrees of antioxidant activity in different test systems in a dose-dependent manner. All solvent extracts of Passiflora wilsonii Hemsl. exhibited scavenging activities toward 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2-azinobis (3-ethyl-benzothiazoline-6-sulfonic acid) diammonium salt (ABTS), superoxide anion and hydroxyl radicals. On the other hand, the ethanol fraction showed the highest antioxidant and antibacterial activities in most instances. This study verified that the ethanol extract have strong antioxidant and antibacterial activities which were correlated with its high level of flavonoids.

“…Leaves are mashed into a plaster and used externally for sprains and strains of joints, tendon, and bone (Huai and Pei 2004). Plant extracts are used for treating rheumatoid arthritis and for postpartum convalescence (Li et al 2006). Some species of Aeschynanthus have been listed as threatened medicinal plants of the Darjeeling Himalayas (Chhetri et al 2005).…”

Plant regeneration through direct somatic embryogenesis in Aeschynanthus radicans 'Mona Lisa' was achieved in this study. Globular somatic embryos were formed directly from cut edges of leaf explants and cut ends or on the surface of stem explants 4 wk after culture on Murashige and Skoog (MS) medium supplemented with N-phenyl-N′-1, 2, 3-thiadiazol-5-ylurea (TDZ) with α-naphthalene acetic acid (NAA), TDZ with 2,4-dichlorophenoxyacetic acid (2,4-D), or 6-benzylaminopurine (BA) or kintin (KN) with 2,4-D. MS medium containing 9.08 μM TDZ and 2.68 μM 2,4-D resulted in 71% of stem explants producing somatic embryos. In contrast, 40% of leaf explants produced somatic embryos when induced in medium containing 6.81 μM TDZ and 2.68 μM 2,4-D. Somatic embryos matured, and some germinated into small plants on the initial induction medium. Up to 64% of stem explants cultured on medium supplemented with 9.08 μM TDZ+2.68 μM 2,4-D, 36% of leaf explants cultured on medium containing 6.81 μM TDZ and 2.68 μM 2,4-D had somatic embryo germination before or after transferring onto MS medium containing 8.88 μM BA and 1.07 μM NAA. Shoots elongated better and roots developed well on MS medium without growth regulators. Approximately 30-50 plantlets were regenerated from each stem or leaf explant. The regenerated plants grew vigorously after transplanting to a soil-less substrate in a shaded greenhouse with more than a 98% survival rate. Three months after their establishment in the shaded greenhouse, 500 plants regenerated from stem explants were morphologically evaluated, from which five types of variants that had large, orbicular, elliptic, small, and lanceolate leaves were identified. Flow cytometry analysis of the variants along with the parent showed that they all had one identical peak, indicating that the variant lines, like the parent, were diploid. The mean nuclear DNA contents of the variant lines and their parent ranged from 4.90 to 4.99 pg 2C −1 , which were not significantly different statistically. The results suggest that the regenerated plants have a stable ploidy level, and the regeneration method established in this study can be used for rapid propagation of ploidystable Aeschynanthus radicans.

“…Both qualitative and quantitative sampling methods may be used when samples are chosen purposively (Table 1, Campbell 1955), such as participant-observation studies (Walker et al 2004), ranking activities, questionnaires (Zhen et al 2006), participatory mapping (Parlee & Berkes 2006), direct observations (Martinez-Romero et al 2004) and interviews (Anderson 2004, Li et al 2006, Ramihantaniariyo et al 2003. Statistical analyses such as logistic regression models (Neupane et al 2002), frequencies, chi-square (Albertin and Nair 2004), analysis of variance (Belcher et al 2004), univariate analysis and cross tabulation (Bah et al 2006), among others, have also been used with purposive sampling.…”

“…Purposive sampling can be applied to research in a number of ways (Table 1), such as in preliminary studies where the researcher is still testing the feasibility of a proposed study (Poggie 1972), sampling informants with a specific type of knowledge or skill (Li et al 2006, Prance 2004, Vargas & van Andel 2005, comparisons of cultural practices (Neupane et al 2002), case studies (Dolisca et al 2007, Parlee & Berkes 2006, and when the population is too small for a random sample (Tran & Perry 2003). The following examples show the context in which purposive sampling has been used, discussing the problem, research method, and results obtained from the study.…”

Informant selection is highly relevant for ethnobotanical research, as people are constantly looked upon for knowledge and information. The purposive sampling technique is a type of non-probability sampling that is most effective when one needs to study a certain cultural domain with knowledgeable experts within. Purposive sampling may also be used with both qualitative and quantitative research techniques. The inherent bias of the method contributes to its efficiency, and the method stays robust even when tested against random probability sampling. Choosing the purposive sample is fundamental to the quality of data gathered; thus, reliability and competence of the informant must be ensured.
