Uchenna AP, Charity ON, Abbey B. Effect of Simultaneous Snail Slime-aided Degradation and Yeast Fermentation on Terpenoid Composition of Plantain Pseudostem Waste. Curr Pharm Biotechnol 2019; 20:459-464. [DOI: 10.2174/1389201020666190408120018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2018] [Revised: 12/15/2018] [Accepted: 04/01/2019] [Indexed: 11/22/2022]
Abstract
Background:
In this study, local sustainable enzyme sources involving excised digestive
juice of African land snail and yeast were utilized to achieve the simultaneous saccharification (SSF)
and fermentation (SSF) of plantain pseudostem (PPS) waste, and afterwards their effects on terpenoids
using gas chromatography coupled to a flame ionization detector (GC-FID), were examined.
Methods:
The most abundant terpenoids were found in the order α-pinene > borneol > camphor > humulene
> β-caryophellene, while the least in abundance were cis ocimene (8.78x10-6 mg/100g), and
cyperene (1.81x10-5 mg/100g). The application of exclusive fermentation and SSF respectively elevated
azuluene by 95.46 and 99.6%, while pinene-2-ol was elevated by 83.02 and 98.57%, respectively.
Results:
Both exclusive fermentation and SSF had no effect on myrcene, cyperene, ethyl cinnamate,
germacrene b, valencene, beta selinene, aromadendrene, and taraxerol, while the degree of degradation
of some of the terpenoids by both processes was respectively as follows; gama muurolene (100%),
β-caryophyllene (97.60 and 93.14%), α-terpinenyl acetate (91.95 and 83.16%), geranyl acetate (94.81
and 43.87%), and terpinen-4-ol (94.40 and 57.00%).
Conclusion:
The findings of this study encourage the imminent application of simultaneous saccharification
and fermentation for the enhancement of bioactivities of terpenoids.

JOURNAL OF ASIAN NATURAL PRODUCTS RESEARCH 2017; 19:766-773. [PMID: 27967214 DOI: 10.1080/10286020.2016.1264394] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2016] [Accepted: 11/21/2016] [Indexed: 06/06/2023]
Abstract
Three new benzolactones (1-3), together with four known ones (4-7), were isolated from the whole herb of Lavandula angustifolia. Their structures were established on the basis of detailed spectroscopic analysis (1D- and 2D-NMR, HRESIMS, UV, and IR) and comparison with data reported in the literature. New compounds were evaluated for their anti-tobacco mosaic virus (TMV) activities and cytotoxic activities. The results revealed that compounds 1-3 showed obvious anti-TMV activities with inhibition rates of 26.9, 30.2, and 28.4%, which were at the same grade as positive control. Compounds 1-3 also showed weak inhibitory activities against some tested human tumor cell lines with IC50 values in the range of 32.1-7.6 μM.
