PREFACE

Pharmacy is a profession which is concerned with the art and science of suitable and

convenient material for distribution and use in the treatment and prevention of disease, so it

is a fully technical profession where practical knowledge is much more important along with

theoretical knowledge. So being a Pharmacy student it is my pleasure and privilege to submit

this dissertation in its present form. The progress of scientific research has been increasing

sustainability in the last two decades particularly in the field of pharmacy. The ultimate

biochemical objective of all these are remain same, to develop better drugs for a specific

disease. Here I have tried to find out the protective effects of antimicrobial drugs.

In this literature review I have written an introduction part where the details about the

herbal drug with its advantage, disadvantage, and definition of antimicrobial activity is

summarized. In this literature review I have shown the reason why I have performed this

project work. The possible literature regarding Leucas plukenetii (Roth)Spreng are written

in literature review section. The reference of my work is given separately.

At last I expect this assignment can give some guidelines about further Phytochemical

and Pharmacological research.

AIM & OBJECTIVES

CHAPTER 1 AIM & OBJECTIVES 2016

GIPS Page 2

1.1. AIM:

Antimicrobial resistance is a growing problem due to overuse of antibiotics in

humans. Many of the currently used antibacterial are associated with adverse effects such as

toxicity, hypersensitivity, immune suppression, and tissue residues posing public health

hazard. As the global scenario is now changing towards the use of non- toxic and eco-friendly

products, development of modern drugs from traditional medicinal plants should be

emphasized for the control of various human and animal diseases. In the present study, the

selection of this plant for evaluation was based on its traditional usages.

So further new alternative remedies for treatment of bacterial diseases are usually

required. Although very few works have been done on the antimicrobial activity of his

medicinal plant, it needs further study for verification of its activity against disease causing

microorganisms. Thus the aim of this project work is the evaluation of the antimicrobial

potency of Leucas plukenetii (F-Laminaceae)

1.2. OBJECTIVES:

The present objective of the study is-

Extraction of active constituents from the dried leaves of Leucas plukenetii

Preliminary Phytochemical screening of the extract of leaves of Leucas plukenetii

Antimicrobial activity of the extract in comparison to suitable standard.

INTRODUCTION

CHAPTER 2 INTRODUCTION 2016

GIPS Page 4

2.1. INTRODUCTION:

The medicinal use of plants is very old. The writings indicate that therapeutic use of plants

is as old as 4000–5000 B.C. and Chinese used first the natural herbal preparations as

medicines. In India, however, earliest references of use of plants as medicine appear in

Rigveda, which is said to be written between 1600-3500 B.C.

Later the properties and therapeutic uses of medicinal plants were studied in detail and

recorded empirically by the ancient physicians in ‘Ayurveda’ which is a basic foundation of

ancient medical science in India [1]. The Hindu Physician, Susruta enlisted seven hundred

and sixty medicinal plant in Ayurveda in the 5th century AD. [2]

Antibiotic resistance is a growing problem. The widespread and indiscriminate use

of antibacterial agents resulted in development of drug resistance among many virulently

pathogenic bacteria species. Many of the currently used antibacterial are associated with

adverse effects such as toxicity, hypersensitivity, immune suppression, and tissue residues

posing public health hazard.

So, further new alternative remedies for treatment of bacterial diseases are usually

required. As the global scenario is now changing towards the use of non- toxic and eco-

friendly products, development of modern drugs from traditional medicinal plants should be

emphasized for the control of various human and animal diseases. [3]

LITERATURE

REVIEW

CHAPTER 3 LITEARATURE REVIEW 2016

GIPS Page 8

3.1. PHYTO-CHEMICAL EVALUATION:

3.1.1. Sadhu et al. (2003) isolated eight lignans namely nectandrin B , (-)-chicanine ,

meso-dihydroguaiaretic acid, macelignan , myristargenol B , erythro-2-(4-allyl-2,6-

dimethoxyphenoxy)-1-(4-hydroxy-3-methoxy phenyl) propan-1-ol, Machilin C, (7R,8R)-

and (7S,8S)-licarin from the methanol extract of the whole plant.

3.1.2. Manivannana and Sukumar (2007) reported free flavonoid ‘baicalein’ was reported in

the ethereal fraction of hydro methanolic extract of flower.

3.1.3. Gerige et al. 2007 & Mangathayaru et al. (2006) found to contain high amount of a-

farnesene, α-thujene and menthol.

3.1.4. A new type of diterpenes, leucasperones A and B ; leucasperols A and B, have been

reported by Sadhu et al. (2006).

3.1.5. Linoleic acid were found which was contingent upon crop variation by Chen et al.,

(1979).

3.1.6. Rajyalakshmi et al., (2001) found Leucas aspera and Leucas cephalotes contain

significant amounts of total carotenoid and β-carotene. [11]

3.2. PHARMACOLOGICAL ACTIVITY:

3.2.1 Antimicrobial activity: Mangathayaru et al., (2005) reported significant antimicrobial

activity was reported for the alkaloidal fraction and the total methanol extract the

flowers [12].

Satyal et al., (2013) reveals that the essential oil of the plant showed no activity

against E. coli, P. aeruginosa, and C. albicans (MIC ≥ 1250μg/mL). The oil did exhibit good

activity against S. aureus (MIC = 625 μg/mL), B. cereus (MIC = 313μg/mL), and A. niger


GIPS Page 9

(MIC = 313 μg/mL), most likely attributable to the sesquiterpenes present in the oil. Both

(E)-caryophyllene and α-humulene have shown antibacterial activity against B. cereus and

S. aureus, and α-humulene was antifungal to A. niger [13]

Ilango et al., (2008) evaluated and found that Ethyl acetate extract (EAE) of whole

plant exhibited moderate to significant and concentration dependent antibacterial activity

against all the tested microorganisms at the concentrations of 50, 100, 200, 300 and 400

µg/disc and comparable to the various antibiotics used for individual microorganism. This

study also reveals that EAE was found to be highly active against Staphylococcus

epidermidis and Klebsiella pneumoniae [14]

Chew et al. (2012) evaluated the antimicrobial activity of crude extracts of root,

flower, leaf having notable antibacterial activity. The root extract showed the highest mean

zone of inhibition ranging from 9.0–11.0 mm at a concentration of 100 mg/mL.[15]

Antony et al. (2013) describes green synthesis of silver nanoparticles (AgNPs)

utilizing the plant. Antimicrobial activity of the AgNPs was tested against Aeromonas

hydrophila. Catla catla, the model organism used for the experiment was divided into six

groups with 15 animals in each group. In vivo analysis of biochemical parameters and

histological architecture provided evidence for the antibacterial effect of AgNPs in the fish

model.[16]

3.2.2 Central nervous system activity: Rahman et al. (2007) found that ethanolic extract of

root showed significant peripheral antinociceptive activity at a dose of 400 mg/kg . [17]

3.2.3 Antioxidant activity: Rahman et al. (2007) reported significant activity was found in

the ethanolic extract of root (IC50 = 7.5 µg/ml) .[17]

Chew et al. (2012) evaluated antioxidant activity methanol extract of root and it

possessed antioxidant activity near the range of vitamin E and thus could be a potential rich

source of natural antioxidant.[15]


GIPS Page 10

3.2.4 Hepatoprotective activity: According to Thenmozhi et al (2013) the Hydroalcoholic

leaf extract has found to possess hepatoprotective property by suppressing the abnormal

elevation of liver enzymes induced by lead acetate . [18]

Mangathayaru et al.,(2005) showed The cold methanolic extract of the whole plant

of was found to exhibit significant hepato protection in CCl4 induced liver damage.[19]

Banu et al. (2012) found that d-galactosamin administration induced hepatotoxicity

in rats which was manifested by increased levels of alanine aminotransferase, aspartate

aminotransferase, alkaline phosphatase, total cholesterol, triglycerides, total bilirubin and

oxidative stress. Pre-treatment with LA extract significantly protected the liver in d-

galactosamin administered rats. LA extract significantly elevated antioxidant enzymes like

superoxide dismutase, catalase, glutathione peroxidase and decreased lipid peroxidation

levels in liver. The total phenolic and flavonoid content in LA aqueous extract was found to

be 28.33 ± 0.19 gallic acid equivalents mg/g of extract and 3.96 ± 0.57 rutin equivalent mg/g

of extract, respectively. LA extract (200 and 400 mg/Kg) treatment with CCl4 decreased the

hexobarbitone-induced sleeping time in mice by 56.67 and 71.30%, respectively, which

indicated the protective effect of LA on hepatic MDMEs. Histological studies showed that

LA at 400 mg/kg attenuated the hepatocellular necrosis in d-galactosamin intoxicated

rats.[20]

3.2.5 Anti-inflammatory activity: Reddy et al. (1986) reported that whole plant extract

have anti-inflammatory activity and caused degranulation of mast cells [17].

Reddy et al. (1986) reported anti-inflammatory activity of the yellow colored

chromatographic fraction of extract was observed in the chronic and acute models of

inflammation. It was observed that, the activity was due to the inhibition of histamine and

serotonin [21].


GIPS Page 11

Similar observations were made by Saundane et al., (2000) and concluded that, on

preliminary screening of ethanol and distilled water extracts exhibited significant anti-

inflammatory activity, whereas only ethanol (95%) extract produced long term analgesia in

the experimental animals. [22]

Srinivas et al. (2000) reported that the dried leaves of for the alcoholic and aqueous

extracts of the plant possessed significant anti-inflammatory activity against carrageenan-

induced paw oedema and cotton pellet induced granuloma. [23]

Goudgaon et al. (2003) concluded that the alkaloid fraction of the crude ethanolic

extract is accountable for the antiinflammatory activity. [24]

3.2.6 Cytotoxicity: Krishnaraju et al. (2005) proves that the hydro alcoholic extract of whole

plant exhibited cytotoxicity (LC50 = 1,900 µg/ml)[16] and this activity was more in the root

extract (LC50 = 52.8µg/ml) [25].

Chew AL et al. (2012) performed brine shrimp lethality bioassay , it was evident

that the methanol root extract did not show significant toxicity. The LC50 value for 12 h and

24 h observation was 2.890 mg/mL and 1.417 mg/mL, respectively. [15]

3.2.7 Larvicidal Activity: Maheswaram et al. (2008) The findings of the present

investigation revealed that L. aspera has good larvicidal activity of the plant activity against

Culex quinquefasciatus Say. and Aedes aegypti [26]

3.2.8 Antihyperglycemic Activity: Mannan et al. (2010) performed an experiment upon

antihyperglycemic activity of plant extract at mice. The methanol extract of leaves, when

administered to glucose-challenged mice demonstrated dose-dependent and significant

antihyperglycemic activity The stem extract also demonstrated significant and dose-

dependent antihyperglycemic activity in glucose tolerance tests in mice. [27]


GIPS Page 12

However, dose for the antihyperglycemic activity demonstrated by stem extract was

lower than that of leaf extract. At the highest dose of 400 mg extract per kg body weight,

serum glucose levels fell by 28.39% versus 34.01% obtained with the same dose of leaf

extract. To summarize, antihyperglycemic activity at a statistically significant level was

observed with leaf extract, when the extract was administered at doses of 200 mg per kg body

weight to glucose-loaded mice. [27]
