“…Later on, in the year 1996, Nayar reported that S. kanarense was considered as a critically endangered species and last seen by Talbot discounting the collection of R. Sundararaghavan. After a long period of 47 years, this plant has been rediscovered from evergreen forests and belongs to the Myrtaceae family (Shenoy et al, 2015). Still, no data available in S. kanarense plant species.…”

Syzygium kanarense (Talbot) Raizada (Family: Myrtaceae), a rare plant tested for toxicity in order to explore therapeutic value. In the current study, the preliminary phytochemical screening, in vitro toxicity and acute toxicity of aqueous extract of Syzygium kanarense leaves (AESKL) were evaluated. Phytochemicals were screened and cytotoxicity was confirmed by MTT assay using NIH/3T3 cell line. For acute toxicity evaluation, female rats were divided into two equal groups; one group served as control while the other group received a single dose of AESKL at 2000mg/kg body weight (b.w) were treated and observed for 14 days. AESKL contains phenolics, tannins, terpenoids, saponins and steroids. The result showed the cytotoxicity value of inhibitory concentration (IC50) = 491.56 µg/ml of AESKL. Acute toxicity of AESKL established the Lethal Dose (LD50) more than 2000 mg/kg b.w and no mortality rate was observed. No changes in behavioural, b.w, relative organ weight, haematological, biochemical and histological were observed. Based on the results, it can be conclude that AESKL do not pose any risk when given orally to rats. To the best of our knowledge, this is the first report on evaluation of in vitro and in vivo toxicity of AESKL.

“…The flowers are white, 0.6-0.8 cm across, nearly sessile, buds globose, creamish white. The fruit is up to 2×1.2 cm with single seed, purple in color when mature, pulpy and crowned with the persistent calyx [1]. S. kanarense was described by Talbot in 1897 from the evergreen forests of the Gerusoppa Ghat in the North Kanara district of Karnataka.…”

“…S. kanarense was described by Talbot in 1897 from the evergreen forests of the Gerusoppa Ghat in the North Kanara district of Karnataka. The species was collected again in 1964 after a gap of 67 years, by R. Sundararaghavan from the Hulical Ghat forests of the adjoining Shimoga District in Karnataka [1]. Nayar (1996) considers this as a critically endangered species and to have last been seen by Talbot discounting the collection of R. Sundararaghavan [2].…”

The hydro-distilled essential oil obtained from the aerial parts of Syzygium kanarense (Talbot) Raizada (Myrtaceae) was investigated for the first time by gas chromatography equipped with flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS). Fifty-two constituents were identified, which represented 91.9% of the total oil. The major compounds were seychellene (7.3%), α-muurolol (5.4%), cis-cadinene ether (5.3%), βvetivenene (5.1%), 10 epi-γ-eudesmol (4.8%), guaiol (4.5%), longiborneol (4.1%), δ-elemene (4.1%) and α-muurolene (4.1%). The oil was found to be rich in sesquiterpene hydrocarbon (49.5%) type constituents.

Syzygium (Myrtaceae) consists of a lot of species which are widely distributed. One of the distribution areas is the Natural Park of Gunung Baung (TWA Gunung Baung) in Pasuruan, East Java. The results of exploration and characterization of known species show that there are six species of Syzygium known to grow in this region namely S. cumini, S. littorale, S. pycnanthum, S. polyanthum, S. racemosum, and S. samarangense. S. pycnanthum is the most frequently found in Gunung Baung. S. polyanthum and S. samarangense are the only species that are known to be cultivated. Four other species are wild and have not been explored for their potential utilization.
