Quantitative and Qualitative Assessment of Phytochemicals in Methanolic Extracts of Hurricane Weed ( Phyllanthus amarus Schumach. &Thonn) Plant
The phytocomponents of the leaf and root extracts of Phyllanthus amarus
(Euphorbiaceae) were studied. The constituents of the leaves and roots
were identified and quantified by using GC-MS. Result from the
phytochemical analyses showed the presence of saponins, tannins,
phenolics, anthocyanins, and glycosides in both leaves and root of the
plant. Alkaloids and triterpenoids were, however only absent in the
root of P. amarus but present in the leaves of the plant. Flavonoids,
coumarins and steroids were absent in the leaves but present in the
root part. The mean concentration of the phytochemicals investigated in
leaves are 0.73\ub10.01%, 1.85\ub10.03%, 1.12\ub10.01%,
1.80\ub10.01%, 1.59\ub10.50%, 0.13\ub10.10%, and 0.86\ub10.01%,
for saponins, tannins, phenolics, anthocyanins, alkaloids,
triterpenoids, and glycosides respectively, while the mean
concentration of the phytochemicals investigated in roots are
0.91\ub10.01%, 1.53\ub10.03%, 0.70\ub10.01%, 2.97\ub10.10%,
2.47\ub10.03%, 0.62\ub10.01%, 0.90\ub10.01% and 2.02\ub10.10%
for saponins, tannins, phenolics, steroids, flavonoids, anthocyanins,
glycosides and coumarins respectively. Furthermore, the GC-MS analysis
of methanol extracts of the leaves and root of P. amarus revealed the
presence of three medicinally important bioactive compounds, which are:
9-Octadecenoic acid which has percentage of abundance of 92.23% and
82.46% in leaves and roots of the plant respectively, followed by
n-Hexadecanoic acid and Tetradecanoic acid with their corresponding
percentage of abundance of 7.7% and 17.54% for leaves and root. These
analytical results suggest the plantto possess a significant role in
phyto-medicine. The importance of this plant was discussed in line with
the role they play in ethnomedicinal life of the people
Farmer perceptions and responses to soil degradation in Swaziland
Soil degradation is globally concerning due to its adverse effects on the environment and agricultural production. Much of Swaziland is at risk from degradation. This paper assesses farmer perceptions and responses to soil degradation in 2002 and 2014, focusing on two land uses that underpin rural livelihoods: arable land and rangeland areas. It uses repeat household surveys and semi-structured interviews, in two case study chiefdoms in the country’s middleveld (KaBhudla and Engcayini) in the first longitudinal study of its kind. We find that observations of land degradation are perceived mainly through changes in land productivity, with chemical degradation occurring predominantly on arable land and physical degradation and erosion mainly in rangeland areas. Changes in rainfall are particularly important in determining responses. While perceptions of the causes and impacts of degradation largely concur with the scientific literature, responses were constrained by poor land availability, shorter and more unpredictable cropping seasons because of changing rains and low awareness, access to or knowledge of agricultural inputs. We suggest that sustainable arable land management can be enhanced through improved access to alternative sources of water, use of management practices that retain soil and moisture and greater access to agricultural inputs and capacity building to ensure their appropriate use. We suggest collaborative management for settlement planning that integrates soil conservation and livestock management strategies such as controlled stocking levels and rotational grazing could improve land quality in rangeland areas. Together, these approaches can help land users to better manage change
Accidental Peno-Scrotal Degloving Injuries in a Child A Case Report and Literature Review
Injury to male external genitalia is very rare because of some intrinsic factors like location, strong investing tunica albuginea and cremasteric muscles. However, when it occurs it is considered a urological emergency. Child labour with poor understanding of risks and safety precautions, especially under harsh supervision, surely poses major challenges. This case illustrates degloving injury of the penis and avulsion of the scrotum in a young boy whileoperating a roller type machine used in palm trees plantation. The penis was primarily regloved and avulsed skin primarily repaired. A good cosmetic outcome was observed from this treatment. This case also illustrates theimportance of early presentation and emergency intervention in this condition.Keywords:- Child Labour, Industrial Accident, degloving Peno-scrotal injury, Urological emergenc
