BRINE SHRIMP LETHALITY TEST

A brine shrimp hatchery made from a plastic soap dish and placed in the light. The shrimp should hatch within 24-48h. Significant if LD50 <30 ug/mL. KUSMARDIYANI

BIOASSAY- Explain -

Adults have three eyes and 11 pairs of legs and can grow to about 15 millimetres in size.

Indeks ikan adalah bilangan atau angka yang menunjukkan pada pengenceranberapa larutan suatu zat membunuh 3 dari 5 ekor ikan yang panjangnya 2 – 4 cmdalam waktu satu jam.

Red blood cells without (left and middle) and with (right) hemolysis. Note that the hemolyzed sample is transparent,

because there are no cells to scatter light.

Chemical Groups

Alkaloid Flavonoid Tannin Quinone Steroid/Triterpenoid ……. …….

Nucleic acid – Plant identification

• RFLP (Restriction fragment length polymorphism)– DNA– Restrictive endonuclease– Gel Electrophoresis– Finger printing (DNA fragment profile)

• RAPD (Random amplified polymorphism of DNA)– DNA– PCR– Gel electrophoresis– Much more simple DNA fragment profile

PHYSICOCHEMICAL PARAMETERS

TO BE MEASURED

• Spectrophotometry/Spectrometry

• Chromatography

PHYSICOCHEMICAL PROPERTIES

• Spectrophotometry–UV-Vis– IR

• Spectrometry– Mass Spectrometry– NMR• Proton NMR• 13C-NMR

PHYSICOCHEMICAL PROPERTIES

--- get more recent information ---

UV-Vis Spectrophotometry

– Qualitative measurement– Quantitative measurement

• Chlorophyl• Carotenoid• Piperin• Curcuminoid


IR Spectrophotometry

• Not much use in analytical pharmacognosy• Suitable for volatile oils• IR profile can be used as one of identity

parameter.


Mass Spectrometry• Not much use in analytical pharmacognosy.

• Its combination with gas chromatography: very useful tool in volatile oil analysis.

• In addition to finger printing, mass spectrum of each component can be obtained and identified base on data base present in system.


NMR Spectrometry

• Not much use in analytical pharmacognosy.

• Very important instrument for structure elucidation of pure compound.


CHROMATOGRAPHY

• Paper chromatography• Thin layer chromatography• Column chromatography• HPLC• GC


Paper Chromatography

• Suitable for polar compound, such as: carbohydrates, phenolics, flavonoids.

• Limited variation of solvent can be used.


Thin Layer Chromatography• Very widely used in analytical pharmacognosy.• Finger printing of crude drug.• Determination of marker.• Chromatographic profiling.• Can be eluted vertically or circularly.• Various composition of solvent

can be used.


THIN LAYER CHROMATOGRAPHY OF CINCHONA BARKS

Developing system: chloroform - diethylamine (9:1) Spray reagent: (a) 10% H2SO4 in ethanol UV365nm

(b) 10% H2SO4, then iodoplatinate reagent visible light

1 = Cinchona calisaya extract 2 = Cinchona succirubra extract TC = a mixture of cinchona alkaloids

T1 = quinine T2 = sinchonidine T3 = quinidine T4 = sinchonine

ATLAS OF PLANT DRUG ANALYSIS

Wagner, TLC Atlas..

Column Chromatography• Suitable for sample preparation.• Mostly use to fractionate chemical

constituents.• Example:

– Analysis of pesticide residue.– Sample clearance

prior to HPLC analysis.


HPLC• High performance

liquid chromatography.• Very widely used in analytical

pharmacognosy.• Can be used for qualitative or

quantitative analysis.

• Detection system varies.• Coupled with Diode Array Detector

provide more information on identity of the peak.


HPLC hyphenated

• Combined with MS (LC-MS) provide better performance of the device.

• More versatile.

• Higher sensitivity for quantitative analysis.

• Better information on identity of each peak by the availability of the mass spectrum of each peak.


Gas Chromatography GC is very suitable for analysis of

volatile oil.

It is also used for the analysis of pesticide residue.

Example:Analysis of Peppermint Oil
